Psychological Strengths and Cognitive Vulnerabilities: Are They Two Ends of the Same Continuum or Do They Have Independent Relationships with Well-being and Ill-being? Veronika Huta Æ Lance Hawley

Abstract Research programs examining psychological strengths and vulnerabilities have remained largely separate, making it difficult to determine the relative contributions of strengths and vulnerabilities to well-being. Two studies (241 normals, 54 depressed outpatients) compared certain psychological strengths (Transcendence subscales, Values In Action Inventory of Strengths) and cognitive vulnerabilities (Dysfunctional Attitudes Scale). In multiple regression, strengths usually related more to positive well-being—life satisfaction, positive affect, vitality, meaning, elevating experience—though vulnerabilities also related to the first three variables; vulnerabilities related more to illbeing— negative affect, depression—though hope, humor, enthusiasm, and forgiveness sometimes also showed relationships. Pre-treatment strengths (hope, spirituality, appreciation of beauty and excellence) predicted post-treatment recovery from depression; cognitive vulnerabilities did not. Strengths and vulnerabilities sometimes interacted, with strengths weakening the relationship between vulnerabilities and well-being. Our findings indicate that strengths and vulnerabilities are not mere opposites (correlating at most moderately) and deserve study as distinct contributors to well-being.

Recently, there has been tremendous growth in research on character strengths and their role in personal well-being—variables such as hope, gratitude, and spirituality have been associated with a variety of well-being outcomes (e.g., Emmons et al. 1998; Emmons and V.

McCullough 2003; Park et al. 2004; Peterson 2006; Peterson et al. 2007; Scheier et al. 2001; Snyder 2000). At the same time, there is a vast and long-standing literature on individual differences in cognitive vulnerabilities—variables such as perfectionism/selfcriticism and excessive need for approval are well known to foster psychological ill-being (e.g., Antony et al. 1998; Blatt 2004; Blatt et al. 1995; Blatt and Zuroff 1992; Brown and Beck 2002; Hawley et al. 2006; Zuroff et al. 2004). To date, these two bodies of literature have remained largely separate. It is therefore unclear how psychological strengths and cognitive vulnerabilities relate to each other, and what their independent relationships are with positive well-being and ill-being. The purpose of the present article was to address these two questions. A review of the existing literature suggests what pattern of results might be expected. Previous research examining cognitive vulnerabilities has largely focused on negative outcomes, such as negative affect and depression (Beck et al. 1983; Flett and Hewitt 2002; Scher et al. 2005). In contrast, the majority of research on character strengths has focused on positive well-being such as life satisfaction, positive affect, and self-esteem (Peterson and Seligman 2004), though there has been some work on their links with ill-being (see review below). If we assume that these two literatures were guided by clinical experience and by other expert observation, then we would expect that vulnerabilities will indeed relate mainly to ill-being, while strengths will primarily relate to positive well-being. Also, a number of studies have examined neuroticism and extraversion simultaneously in relation to well-being. The operationalization of these traits includes characteristics that are strengths and vulnerabilities, such as activity/enthusiasm as a facet of extraversion, and self-consciousness/self-criticism as a facet of neuroticism. Studies comparing neuroticism and extraversion have often found that neuroticism was more related to ill-being, while extraversion was more related to positive well-being (e.g., Costa and McCrae 1980; McCrae and Costa 1991). Furthermore, there is evidence to suggest that the psychological and brain mechanisms underlying positive affect and negative affect are to some degree distinct (Davidson and Irwin 1999; Davidson et al. 2000; Diener and Emmons 1984; Diener and Iran-Nejad 1986; Elliot and Thrash 2002; Watson and Tellegen 1985). This lends further support to the idea that positive and negative well-being may have different correlates, and raises the possibility that strengths primarily interact with the mechanisms involving positive experiences, while vulnerabilities primarily interact with negative experiences. Based on these considerations, we had the following predictions for the studies presented here: (1) strengths and vulnerabilities will not correlate strongly enough to suggest that they are simply opposite ends of the same continuum; (2) strengths will more consistently and more strongly have independent relationships with positive well-being than will vulnerabilities; (3) vulnerabilities will more consistently and more strongly have independent relationships with ill-being than will strengths. There were two additional topics we wished to investigate in this research. First, one of our samples consisted of clinically depressed outpatients whom we assessed before and after they received a standardized cognitive behavior therapy intervention. We were therefore in a position to study the power of pre-treatment strengths and vulnerabilities to predict post-treatment reduction of depression symptoms. Quite a few studies have examined the influence of pre-treatment cognitive vulnerabilities or changes in cognitive vulnerabilities early in treatment on the level of symptoms later in treatment or at the end of treatment—the majority have found a significant effect (Blatt et al. 1995, 1998; DeRubeis et al. 1990; Hamilton and Dobson 2002; Hawley et al. 2006; Shahar et al. 2003), although a few have found no effect (Jarrett et al. 2007; Kwon and Oei 2003; Otto et al.

2007). We therefore hypothesized that pre-treatment vulnerabilities would predict degree of depression recovery at post-treatment. We also expected strengths to play a predictive role—while we expected strengths to relate less to initial depression severity than vulnerabilities would, we thought that strengths may play some role in depression recovery, to the degree that recovery represents active movement towards positive well-being. Although little research has examined the impact of strengths on depression reduction in a therapy setting, several studies have shown that: character strengths predict a decrease in depression symptoms over time (Braam et al. 1997, 2004; Nezu et al. 1988; Orcutt 2006); interventions aimed at promoting strengths can significantly reduce depression symptoms (Cheavens et al. 2006; Gillham 2000; Reed and Enright 2006; Seligman et al. 2005, 2006); and strengths can reduce the toll of mental illness on life satisfaction (Peterson et al. 2006). Thus, we expected both pre-treatment vulnerabilities and strengths to predict post-treatment depression improvement, though we did not have a prediction about the relative magnitudes of these influences. The final topic we wished to address concerned the interaction of strengths and vulnerabilities when predicting well-being. Little work has specifically focused on this question. Strengths and vulnerabilities might interact in different ways: (1) vulnerabilities may undermine the benefits of strengths, such that strengths have weaker links with wellbeing among highly vulnerable individuals; (2) alternatively, strengths may be especially important in cases of high vulnerability, such that strengths have stronger links with wellbeing among highly vulnerable individuals. We planned to test these competing hypotheses in our studies. Psychological strengths were assessed using the transcendence scales of the Values in Action Inventory of Strengths (VIA-IS) (Peterson and Seligman 2001, 2004), which is the most comprehensive cross-culturally validated measure of psychological strengths. The VIA-IS measures a total of 24 psychological strengths and virtues. However, in one of the populations we planned to study, a clinically depressed sample, we could not assess all 24 VIA-IS strengths due to time constraints. We therefore focused on a subset of strengths throughout this article—the subset that Seligman (2002) identified as representing a capacity for transcendence, i.e., having a broader perspective beyond immediate concerns. The transcendence strengths are hope, enthusiasm, humor, gratitude, appreciation of beauty and excellence, spirituality, and forgiveness. We chose the transcendence group because it includes the majority of strengths most related to positive well-being in past research, including hope, enthusiasm, gratitude, and spirituality (Park et al. 2004; Peterson et al. 2007; Peterson 2006). In addition, more often than any other cluster of VIA-IS strengths, the strengths in the transcendence cluster have been linked with depression and negative affect (see review below). We might also expect a relationship between transcendence and ill-being from a conceptual standpoint—negative affect and depression are related to a narrow and rigid attentional focus, which is the opposite of a transcendent perspective (Compton 2000; Ingram 1990; Nolen-Hoeksema 2000; Seligman 1990). We assessed psychological vulnerabilities using the Dysfunctional Attitudes Scale (DAS) (Weissman and Beck 1978), the most widely used measure of cognitive vulnerability, which has been studied in relation to a variety of mental disorders, most often major depression (e.g., Brown and Beck 2002; DeRubeis et al. 1990; Golden et al. 2006; Rector 2004; Wright et al. 2005; Zuroff et al. 1999. The DAS measures individual differences in various dysfunctional tendencies, including perfectionism and excessive need for approval from others (Cane et al. 1986; Imber et al. 1990). We tested our hypotheses in two populations, using several different well-being variables. In our first study, we investigated psychologically healthy individuals to compare

strengths and vulnerabilities in relation to several positive well-being measures, as well as negative affect and depression. The positive outcomes included those most commonly studied—life satisfaction, positive affect, and self-esteem. They also included several other outcomes, in the interest of assessing well-being more broadly: vitality, a positive feeling of aliveness and energy (Ryan and Frederick 1997); a sense of meaning as a well-being outcome (Huta and Ryan 2008); and elevating experience, which includes awe, moral elevation and inspiration, and a sense of connection with a greater whole (Huta and Ryan 2008). All three of these additional well-being variables have proven to be distinct from more routinely assessed concepts, and have contributed important information about the well-being benefits of various individual differences (Huta and Ryan 2008; Huta and Grouzet 2008; McGregor and Little 1998; Nix et al. 1999; Prosnick 1997; Ryan and Frederick 1997). In our second study, we expanded our analysis of negative outcomes by following clinically depressed clients and measuring their depression severity both before and after they received therapy. In addition to testing our general hypotheses about strengths, vulnerabilities, and wellbeing, the present research permitted us to address several specific gaps in the literature, regarding zero-order correlations between certain well-being variables and certain strengths or vulnerabilities. While the transcendence strengths have been related to life satisfaction, positive affect, and self-esteem (Peterson and Seligman 2004), less is known about their links with vitality, meaning, and elevating experience, though a few of these links have been established. Vitality is related to enthusiasm (Peterson and Seligman 2004), meaning has often been linked with spirituality (e.g., Park 2006; Steger and Frazier 2005; Wong 1998), and aspects of elevating experience have been related to both spirituality (Emmons 2000; Keltner and Haidt 2003; Underwood and Teresi 2002; Seidlitz et al. 2002) and appreciation of beauty and excellence (Haidt 2000, 2003; Keltner and Haidt 2003; Peterson and Seligman 2004). However, little is known about the remaining links between the transcendence strengths and vitality, meaning, and elevating experience. Depression and negative affect have been linked with most of the transcendence strengths, though little work has addressed their links with appreciation of beauty and excellence. Depression and negative affect have clearly shown negative links with hope/ optimism (e.g., Abramson et al. 1989; Chang 2001; Chang and DeSimone 2001; Cheavens et al. 2006; Gillham 2000), spirituality (e.g., Baetz et al. 2002; Braam et al. 2004; Kendler et al. 2003; Mofidi et al. 2006; Park et al. 1990; Smith et al. 2003), forgiveness (e.g., Brown 2003; Lawler-Row and Piferi 2006; Orcutt 2006; Reed and Enright 2006; Thompson et al. 2005), and humor (e.g., Kuiper et al. 2004; Martin et al. 2003; Nezu et al. 1988; Thorson et al. 1997). A number of studies have shown negative links of depression and negative affect with gratitude (McCullough et al. 2002; Seligman et al. 2005, 2006; Wood et al. 2007). Also, though little research has explicitly studied the correlations of depression and negative affect with enthusiasm, the related concept of low interest and pleasure in life is a diagnostic symptom of depression (Diagnostic and Statistical Manual of Mental Disorders, DSM-IV-TR). Perfectionism, need for approval, and dysfunctional attitudes in general have clearly been linked to depression and negative affect, but less is known about their relationship with certain forms of positive well-being. These vulnerabilities have often been linked with low self-esteem (e.g., Ashby and Rice 2002; Flett and Hewitt 2002; Grzegorek et al. 2004; Rice et al. 1998; Stumpf and Parker 2000). In addition, a number of studies have shown links with low positive affect (Besser et al. 2004; Dunkley et al. 2003, 2006; Frost et al. 1993; Kobori and Tanno 2005; Molnar et al. 2006; Saboonchi and Lundh 2003) and low life satisfaction (Chang 2000; Gilman and Ashby 2003; Gilman et al. 2005; Rice and

Ashby 2007). However, no research has been conducted on the relationship of dysfunctional attitudes with vitality, meaning, or any of the aspects of elevating experience. In sum, our research was an opportunity to more fully address the links between strengths, vulnerabilities, and different forms of well-being.

1 Study 1: Strengths versus Vulnerabilities in a Normal Sample Our first study was conducted in a non-depressed sample and focused on a variety of positive well-being variables as well as on negative affect and depression. 1.1 Method 1.1.1 Participants Participants were 241 undergraduates at a private university in the northeast U.S. Their mean age was 19.61 years (SD = 1.45); 66% were female; and 66% were White, with 17% Asian, 6% Hispanic, 5% Black, 3% East Indian/Pakistani, 1% Middle Eastern, and 1% of mixed ethnic origin. 1.1.2 Procedure Participants completed the study as a 30-min web-based survey. The survey was one of many studies that participants could choose from on a standardized web-based system, to obtain credit in psychology courses. 1.1.3 Measures 1.1.3.1 Values in Action Inventory of Strengths (VIA-IS); Peterson and Seligman 2001) This measure was developed to assess psychological strengths that are valued across different cultures. Each strength is represented by a 10-item scale. We assessed the seven transcendence strengths: enthusiasm (Cronbach’s alpha a = .83 in the present study), hope (a = .84), humor (a = .87), gratitude (a = .84), appreciation of beauty and excellence (a = .85), spirituality (a = .88), and forgiveness (a = .87). Participants are asked to describe ‘‘what you are like.’’ Items are rated on a 5-point Likert-type scale from ‘‘very much unlike me’’ to ‘‘very much like me.’’ 1.1.3.2 Dysfunctional Attitudes Scale (DAS; Weissman and Beck 1978) This scale was originally developed to assess cognitive vulnerabilities that predispose people to depression and has since been used in research on depression and many other disorders. Form A of the DAS was used in this research, which has 40 items and has demonstrated good psychometric properties (Dobson and Breiter 1983; Weissman and Beck 1978). There are two subscales that researchers often employ, originally derived by principal components analysis with Varimax rotation: a 15-item subscale measuring perfectionism (a tendency to engage in an overly harsh, self-critical style when failing to meet self-imposed standards), and an 11-item subscale measuring need for approval (a tendency to place excessive importance on other peoples’ judgments) (Imber et al. 1990). In the current research, the full 40-item DAS Total scale as well as the perfectionism and need for approval subscales

were employed. The items were scored on a 7-point scale from ‘‘totally disagree’’ to ‘‘totally agree.’’ In the present study, Cronbach’s alpha for the DAS Total was .93, for perfectionism was .91, and for need for approval was .80. 1.1.3.3 Beck Depression Inventory, Second Edition (BDI-II; Beck et al. 1996) This is the most widely used measure of depression severity. It is a self-report questionnaire consisting of 21 multiple-choice questions about key depression symptoms such as sadness, pessimism, and loss of pleasure, rated from 0 (absence of symptom) to 3 (severe manifestation of symptom). We used 20 of the items, omitting one item inquiring about suicidal ideation, because this research was conducted in a non-clinical setting and there was not adequate clinical support to deal with reports of suicidality. Participants indicated how they felt during the past month. The BDI-II has very good psychometric properties (e.g., Beck et al. 1996; Steer et al. 1997). The alpha for the 20 items in the present study was .89. 1.1.3.4 Satisfaction with Life Scale (SWLS; Diener et al. 1985) This 5-item scale measures global satisfaction with one’s life. Sample items are: ‘‘I am satisfied with my life’’ and ‘‘in most ways, my life is close to my ideal.’’ The scale is rated from 1 (strongly disagree) to 7 (strongly agree). The alpha was .87. 1.1.3.5 Positive Affect and Negative Affect (Diener and Emmons 1984) These were assessed by a commonly used set of nine items. Positive affect was assessed with ‘‘happy,’’ ‘‘joyful,’’ ‘‘pleased,’’ and ‘‘enjoyment/fun;’’ negative affect items was assessed with ‘‘unhappy,’’ ‘‘depressed,’’ ‘‘worried/anxious,’’ ‘‘angry/hostile,’’ and ‘‘frustrated.’’ For these and all remaining well-being items below, participants were asked to report ‘‘how you typically feel.’’ The items were rated from 1 (not at all) to 7 (extremely). Alphas were .86 for positive affect and .82 for negative affect. 1.1.3.6 Self-Esteem (Robins et al. 2001) This was assessed using a well-validated singleitem measure that reads ‘‘I have high self-esteem,’’ rated from 1 (not at all true) to 7 (very much true). 1.1.3.7 Subjective Vitality Scale (Bostic et al. 2000) This was assessed using the 6-item version of the trait Subjective Vitality Scale from Bostic et al. (2000), which omits one item from the scale originally developed by Ryan and Frederick (1997). The Bostic et al. (2000) version correlates .98 with the original scale and produces a better-fitting model. Sample items are: ‘‘I have energy and spirit,’’ and ‘‘I feel energized.’’ The items are rated from 1 (not at all true) to 7 (very much true). The alpha was .92. 1.1.3.8 Meaning (Huta and Grouzet 2008) This concept was assessed as a well-being outcome state rather than a way of life (e.g., having a framework for interpreting events, having a purpose) (Huta and Ryan 2008). It was assessed using a 12-item scale by Huta and Grouzet (2008) which consists of three facets: how meaningful one feels that one’s activities and experiences have been, how valuable one feels they have been, and how broad one feels that their implications have been. The items are ‘‘meaningful,’’ ‘‘full of significance,’’ ‘‘making a lot of sense to me,’’ ‘‘I could see how they all added up,’’ ‘‘valuable,’’ ‘‘precious,’’ ‘‘something I could treasure,’’ ‘‘dear to me,’’ ‘‘playing an important role in some broader picture,’’ ‘‘contributing to various aspects of myself,’’ ‘‘I could see where they fit into the bigger picture,’’ and ‘‘they contributed to my community

or the broader world.’’ The items are rated from 1 (not at all) to 7 (extremely). Huta and Grouzet (2008) showed that all 12 items load onto a single factor that is distinct from factors representing other forms of well-being, including positive affect, negative affect, life satisfaction, self-esteem, vitality, and elevating experience. The alpha in the present study was .95. 1.1.3.9 Elevating Experience (Huta and Grouzet 2008) This concept—which includes feelings of awe, inspiration and moral elevation, and connection with a greater whole— was proposed by Huta and Ryan (2008) as an important form of well-being that provides valuable information about the benefits of certain individual differences. We used the 12item version from Huta and Grouzet (2008), who showed that the items load onto a single factor that is distinct from factors representing other forms of well-being, including positive affect, negative affect, life satisfaction, self-esteem, vitality, and meaning. The items are ‘‘in awe,’’ ‘‘in wonder,’’ ‘‘deeply appreciating,’’ ‘‘profoundly touched by experiences,’’ ‘‘emotionally moved,’’ ‘‘inspired,’’ ‘‘enriched,’’ ‘‘spiritually uplifted,’’ ‘‘part of some greater entity,’’ ‘‘part of something greater than myself,’’ ‘‘connected with a greater whole,’’ and ‘‘like I was in the presence of something grand.’’ They are rated from 1 (not at all) to 7 (extremely). The alpha in the present study was .91. 1.2 Results and Discussion Of the 33 analyses examining links between the demographic variables and the DAS subscales, the DAS Total score, the seven transcendence scales, and their composite, 28 (85%) were non-significant. The exceptions were as follows: age was negatively related to humor (r = -.14, p \ .05); females reported higher gratitude than males (t = 2.01, p \ .05); and Whites reported higher humor (t = 2.63, p \ .01), lower spirituality (t = 3.36, p \ .01), and lower perfectionism (t = 2.26, p \ .05) than Non-Whites. The left half of Table 1 shows the Study 1 zero-order correlations between the two DAS subscales, the DAS total score which served as a proxy for ‘‘vulnerabilities in general,’’ the seven VIA-IS transcendence scales, and a composite of the transcendence scales which Table 1 Zero-order correlations of strengths and vulnerabilities Study 1—normal sample Perfectionism Need approval

served as a proxy for ‘‘strengths in general’’ and which was computed by taking the mean of the seven transcendence scales. A total of 22 of the 24 correlations were significantly negative, indicating some shared variance between strengths and vulnerabilities—vulnerabilities may undermine or limit the development of strengths to some extent, or strengths may provide some resilience against vulnerabilities. However, the correlations were at most moderate, ranging from -.03 to -.43. Thus, the correlations were not strong enough to suggest that any of the strengths are simply the opposite of certain vulnerabilities. This provided one form of evidence for the distinctiveness of strengths and vulnerabilities. Furthermore, an exploratory principal components analysis of the seven transcendence scales and the perfectionism and need for approval scales showed that two factors had eigenvalues of 1 or greater, and together accounted for 62% of the variance. The solution was Varimax rotated and the seven strength scales and the two vulnerability scales separated cleanly onto the two factors. Table 2 shows the zero-order correlations between the strengths and the well-being and ill-being variables. All of the transcendence strengths correlated with each positive wellbeing variable. Thus, we replicated past research showing their links with life satisfaction, positive affect, and self-esteem, as well as the links between vitality and enthusiasm, between meaning and spirituality, and between elevating experience and both spirituality and appreciation of beauty and excellence. In addition, our data revealed that vitality, meaning, and elevating experience related to all of the other transcendence strengths. In Table 2, the strengths of hope, enthusiasm, humor, gratitude, and forgiveness related negatively to both negative affect and depression, replicating past research showing their links with ill-being. The one result that differed from past research was the absence of a relationship between ill-being and spirituality. We are unsure why this was a null result. Perhaps it occurred because of the particular constellation of items on the VIA-IS spirituality scale—past findings have varied depending on the elements of spirituality measured, such as public versus private spirituality (Baetz et al. 2002, 2004; Bosworth et al. 2003; Braam et al. 2004). Past studies have not examined a link between ill-being and appreciation of beauty and excellence—our finding suggests that the two constructs are unrelated. Table 2 also shows the zero-order correlations between vulnerabilities and well-being. DAS vulnerabilities correlated positively with both measures of ill-being, as in past research. The vulnerabilities also had significant negative relationships with each measure of positive well-being. Past studies have already shown that vulnerabilities relate to life satisfaction, positive affect, and self-esteem. However, little research has studied their links with vitality, meaning, or elevating experience—our findings show that vulnerabilities relate to these well-being states as well. The findings in Table 3 address our general hypotheses about the relative roles of strengths and vulnerabilities in well-being. The first eight rows show the partial correlations of strengths with well-being when controlling for the DAS total score. These partial correlations are estimates of how much strengths relate to well-being beyond the role of vulnerabilities. About 43 of the 48 links between positive well-being and strengths remained significant, though appreciation of beauty and excellence and spirituality ceased to relate to life satisfaction or self-esteem, and forgiveness ceased to relate to life satisfaction. Thus, strengths usually had relationships with positive well-being that extended over and above the relationship that vulnerabilities had with positive well-being. This supported our expectation that strengths would have a unique relationship with positive outcomes that cannot be reduced to the role of vulnerabilities. Four well-being variables consistently had unique links with all of the transcendence strengths—positive affect,

vitality, meaning, and elevating experience. The links with elevating experience were especially strong. Thus, the less commonly studied outcomes—vitality, meaning, and elevating experience—proved to be important markers of psychological strengths and virtues. While the strengths retained most of their links with positive well-being when controlling for vulnerabilities, exactly half of their correlations with ill-being ceased to be significant. More specifically, gratitude, appreciation of beauty and excellence, and spirituality did not relate to the ill-being variables beyond vulnerabilities. Nevertheless, several strengths did show unique relationships with at least one of the ill-being measures—hope, enthusiasm, and humor related to depression, and humor and forgiveness related to negative affect. While each of these strengths have shown zero-order correlations with distress in past research, our findings demonstrate that they retain these links even when controlling for well-known vulnerabilities. These results strengthen the argument that certain strengths warrant attention in the distress literature, and that an exclusive focus on vulnerabilities would be incomplete. The last three rows of Table 3 show the partial correlations of DAS vulnerabilities with well-being when controlling for the transcendence composite. These partial correlations are estimates of how much vulnerabilities relate to well-being beyond the role of strengths. While five of the six links with ill-being remained significant, eight of the 18 links with positive well-being ceased to be significant. Thus, we found support for our predictions that strengths would have more consistent unique relationships with positive well-being, while vulnerabilities would have more consistent unique relationships with ill-being. Vulnerabilities no longer had unique relationships with vitality or elevating experience, though they did show some unique relationships with life satisfaction, positive affect, self-esteem, and meaning. This raised the possibility that vulnerabilities may undermine some positive outcomes and are worthy of study in the positive well-being literature, where they are usually ignored. Our finding that need for approval did not show a unique relationship with one of the ill-being variables, depression, was unexpected. Our pattern of findings did, however, parallel most past research in the sense that perfectionism was the vulnerability that related more strongly to distress (e.g., Blatt et al. 1995, 1998). To compare the unique contributions of strengths and vulnerabilities numerically, we conducted multiple regressions with the transcendence composite and the DAS total as the independent variables and each well-being variable as the dependent variable, with all variables standardized. We then used a t-test to compared the regression coefficients for the transcendence composite and the DAS total, dropping negative signs so that only the magnitudes of the coefficients were compared. The formula used to compare the coefficients for variables A and B was as follows: Coefficient A  Coefficient B t ¼ pffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi VarianceCoefficient A þ VarianceCoefficient B  2CovarianceCoefficients AB Compared to the DAS total, the transcendence composite had significantly greater unique relationships with all of the positive well-being variables except self-esteem: life satisfaction (t = 2.66, p \ .01), positive affect (t = 4.38, p \ .01), self-esteem (t = 1.94, p [ .05), vitality (t = 8.52, p \ .01), meaning (t = 7.31, p \ 01), and elevating experience (t = 9.20, p \ .01). Compared to the transcendence composite, The DAS total had significantly greater unique relationships with both ill-being variables: negative affect (t = 3.76, p \ .01), and depression (t = 2.47, p \ .05). This supported our prediction that

123

strengths would have greater unique relationships with positive outcomes, while vulnerabilities would have greater unique relationships with negative outcomes. Finally, we tested whether strengths and vulnerabilities interact when predicting wellbeing. The DAS total score was again used as an estimate of ‘‘vulnerabilities in general’’ and the transcendence composite was used as an estimate of ‘‘strengths in general.’’ Multiple regressions were conducted, where each well-being variable standardized was regressed on the DAS total standardized, the transcendence composite standardized, and the product of the DAS total standardized and the transcendence composite standardized. The interaction term was significant in the case of self-esteem (unstandardized B = .14, p \ .05), meaning (B = .12, p \ .05), and depression (B = -.19, p \ .01), but not in the case of life satisfaction (B = .00, p [ .05), positive affect (B = .08, p [ .05), vitality (B = .05, p [ .05), elevating experience (B = .01, p [ .05), or negative affect (B = -.04, p [ .05). To further investigate the interactions that were significant, we used a median split on the transcendence composite to divide the sample into two groups, and then regressed each well-being variable standardized on the DAS total score standardized. We report the results separately for the positive well-being variables (self-esteem and meaning) and the ill-being variable (depression), as the patterns of results were slightly different. Among participants who were low on the transcendence composite, DAS vulnerabilities had a significant negative impact on self-esteem (B = -.52, p \ .01) and meaning (B = -.30, p \ .01). However, among those who were high on transcendence strengths, DAS vulnerabilities had no impact on self-esteem (B = -.11, p [ .05) or meaning (B = .05, p [ .05). Thus, for these positive outcomes, strengths and vulnerabilities interacted such that a high degree of character strengths eliminated the negative impact of vulnerabilities. Conversely, a high degree of vulnerability did not entirely undermine the beneficial effects of strengths—in fact, strengths showed their greatest benefit among those who were high on vulnerability. We found this when we regressed the well-being variables standardized on the transcendence composite standardized: strengths significantly predicted self-esteem and meaning both when the individual was below the median on the DAS total (B = .23, p \ .01, and B = .36, p \ .01, respectively) and above the median (B = .54, p \ .01, and B = .63, p \ .01, respectively), and the effects were particularly strong for individuals who were high on vulnerabilities. Parallel analyses were carried out for the negative outcome of depression. DAS vulnerabilities had an impact whether people were low on strengths (B = .62, p \ .01) or high on strengths (B = .20, p \ .05), though high strengths did weaken the link between vulnerabilities and depression to some degree. Transcendence strengths only predicted reduced depression when vulnerabilities were high (B = -.42, p \ .01), but not when vulnerabilities were low (B = -.03, p [ .05). Overall, our findings demonstrate that strengths and vulnerabilities do in some cases interact. A high degree of strengths eliminated the relationship between vulnerabilities and the positive outcomes of self-esteem and meaning. High strengths also reduced the link between vulnerability and depression, but did not eliminate it, reinforcing the conclusion that vulnerabilities play a key role in ill-being. On the other hand, a high degree of vulnerability did not undermine the relationship between strengths and self-esteem, meaning, or depression. On the contrary, it was in the case of high vulnerability that strengths had their greatest relationship with well-being. Though the findings were correlational, they suggest that strengths may immunize people against the detrimental effects of vulnerabilities, especially when it comes to positive outcomes, while vulnerabilities do

123

not undermine the benefits of strengths. In fact, strengths may be all the more important for highly vulnerable individuals.

2 Study 2: Strengths versus Vulnerabilities in a Clinically Depressed Sample While Study 1 examined a healthy population and a variety of positive well-being variables, our second study focused on a clinically depressed population and provided a more detailed analysis of ill-being. We assessed clients’ depression severity, DAS vulnerabilities, and VIA-IS transcendence strengths both before and after therapy. Thus, we could conduct correlational analyses with pre-treatment depression severity as well as longitudinal analyses to predict post-treatment depression reduction. 2.1 Method 2.1.1 Participants Participants were adult outpatients at the Allan Memorial Hospital in Montreal, Canada who attended group cognitive behavioral therapy for major depression. Following referral by a physician, the Structured Clinical Interview for DSM-IV (SCID-IV; First et al. 1996) was administered to clients by trained clinical psychology doctoral students, and a diagnosis was assigned. Clients were excluded from the group therapy if they had ever met a SCID-IV diagnosis of Bipolar Disorder, Schizoaffective Disorder, Schizophrenia, or Substance Abuse Disorder. All clients consented to participate in research at the beginning of their assessment. Of the 76 clients participating in the group therapy, 54 were included in our analyses because they met the following criteria: (a) their intake score on the BDI-II was at least 14, the cut-off used to indicate at least mild depression (Beck et al. 1996); (b) Major Depressive Disorder was their primary diagnosis; and c) they received and completed the questionnaires we planned to analyze. Of the 54 participants, 66% were female, their mean age was 46.40 years (SD = 12.44); and their mean score on the BDI-II was in the moderate to severe range (28.53, SD = 8.23). The cognitive-behavioral group treatment was based on the standardized ‘‘Mind Over Mood’’ protocol (Greenberger and Padesky 1995) involving weekly sessions of 2 h each. Treatment consisted of psychoeducation regarding the nature of depression, behavioral activation (e.g., engaging in pleasant events), cognitive restructuring, behavioral experiments and action plans, as well as core belief work (e.g., identifying and challenging entrenched patterns of depressive thinking). These activities were practiced both during therapy sessions and as homework exercises between sessions. There were four to seven clients per therapy group and different therapists lead different groups. Data were collected over 4 years in a total of 12 therapy groups. 2.1.2 Procedure Prior to the first therapy session and again at termination, clients completed the following battery of questionnaires.

2.1.3 Measures 2.1.3.1 Values in Action Inventory of Strengths (VIA-IS; Peterson and Seligman 2001) We administered the seven transcendence scales of the VIA-IS as in Study 1. 2.1.3.2 Dysfunctional Attitudes Scale (DAS; Weissman and Beck 1978) was the same as in Study 1.

This measure

2.1.3.3 Beck Depression Inventory, Second Edition (BDI-II; Beck et al. 1996) This measure was the same as in Study 1, except that clients completed all 21 items, including the one inquiring about suicidal ideation, and they indicated how they felt during ‘‘the past 2 weeks, including today’’ rather than during the past month. 2.2 Results and Discussion The right half of Table 1 shows the Study 2 pre-treatment zero-order correlations between the DAS subscales, the DAS total score, the VIA-IS scales, and the transcendence composite. While all but two of the correlations in Study 2 appeared smaller than the corresponding correlations in Study 1, t-tests showed that these differences were not statistically significant, with the exception of the correlations between humor and perfectionism (z = 2.13, p \ .05) and between gratitude and the DAS total (z = 2.32, p \ .05). Thus, future research will be needed to determine whether correlations between strengths and vulnerabilities differ in magnitude across different populations. Nevertheless, the main hypothesis of interest here was supported: the correlations in Study 2 ranged from .02 to -.30, providing further evidence that strengths and vulnerabilities are distinct and cannot be considered opposite ends of a single dimension. The last column of Table 2 shows the Study 2 pre-treatment zero-order correlations of depression with VIA-IS strengths and DAS vulnerabilities. None of the correlations with strengths were significant. This differed from our findings in Study 1, where depression correlated with hope, enthusiasm, humor, gratitude, and forgiveness. However, t-tests comparing corresponding correlations in the two studies showed that none of them differed significantly. Also, the magnitudes of most of the correlations in Study 2 were great enough that they may have reached significance with a larger sample size. Thus, perhaps the non-significance of the correlations between depression and strengths was a matter of sample size. The Study 2 correlations between depression and vulnerabilities were all significant, as in Study 1, and t-tests showed that none of the corresponding correlations in the two studies differed significantly. This replicated many past findings that DAS vulnerabilities are related to the severity of major depression. The last column of Table 3 shows the Study 2 pre-treatment partial correlations of depression with strengths when controlling for the DAS total score (first eight rows), and with vulnerabilities when controlling for the transcendence composite (last three rows). None of the strengths showed a unique relationship with depression. This differed from Study 1, where hope, enthusiasm, and humor did show unique relationships. Although t-tests indicated that none of the partial correlations with strengths differed from the corresponding ones in Study 1, the magnitudes of these partial correlations in Study 2 were quite small. This raised the possibility that strengths play a weaker role in clinically significant depression than they do in milder depression symptoms—further research will be needed to address this possibility with greater certainty. The vulnerability measures did

123

Strengths versus Vulnerabilities

85

show unique relationships with depression, and t-tests showed that the partial correlations did not differ from the corresponding ones in Study 1. This reinforced past findings on the link between vulnerabilities and distress, showing that this link exists even when controlling for several important strengths. In addition, the overall pattern of results in the last column of Table 3 supported our prediction that vulnerabilities would have more consistent unique relationships with ill-being than would strengths. To compare the unique contributions of strengths and vulnerabilities numerically, we conducted a multiple regression with the transcendence composite and the DAS total as the independent variables and depression as the dependent variable, with all variables standardized. We then computed a t-test to compare the magnitudes of the regression coefficients for the transcendence composite and the DAS total, as in Study 1. The DAS total had a significantly greater unique relationship with depression than did the transcendence composite (t = 2.39, p \ .05), supporting our prediction that distress would have a stronger unique relationship with vulnerabilities than with strengths. We also tested whether strengths and vulnerabilities interacted when predicting depression. We regressed pre-treatment depression standardized on the pre-treatment DAS total standardized, the pre-treatment transcendence composite standardized, and the product of the pre-treatment DAS total standardized and the pre-treatment transcendence composite standardized. The interaction term was not significant (B = .21, p [ .05). This differed from Study 1, where strengths and vulnerabilities did interact to predict depression. The interaction analysis in Study 2, like the partial correlations, raises the possibility that strengths may play less of a role in clinically severe depression than they do in milder depression symptoms (compared to the mean BDI-II score of 28.53 in Study 2, which fell in the moderate to severe depression range, the mean BDI score in Study 1 was only 9.79, in the non-depressed range). In our final set of analyses, we tested whether strengths and vulnerabilities could be used to predict degree of recovery from depression. In these analyses, we included only participants who completed an adequate number of therapy sessions, so that they could be viewed as having truly participated in an effort at recovery. We considered clients who completed at least eight of the 12 sessions as treatment completers. There were 38 completers in total. A number of significant findings emerged. The first column of Table 4 shows the partial correlations of post-treatment depression with pre-treatment strengths when controlling for pre-treatment depression. This approach permitted an assessment of depression improvement, regardless of initial depression severity. The strengths of hope, appreciation of beauty and excellence, and spirituality, as well as the transcendence composite, predicted a reduction in depression symptoms. In contrast, none of the vulnerability measures predicted a reduction in depression. The latter result differed from the majority of past studies which did find that initial vulnerabilities predicted later treatment outcome. Past results have not been unequivocal, however: several studies found no relationship between pretreatment dysfunctional attitudes and depression reduction, and researchers have generally found that vulnerabilities are better at predicting initial depression symptoms than degree of recovery (Barnett and Gotlib 1988; Jarrett et al. 2007; Kwon and Oei 2003; Otto et al. 2007). Our results fit with this general pattern. The middle column of Table 4 shows the contribution of pre-treatment strengths to depression improvement beyond the role played by pre-treatment vulnerabilities. Hope, appreciation of beauty and excellence, spirituality, and the transcendence composite still showed significant effects. This contributed important new evidence that pre-existing strengths can influence the success of cognitive-behavioral therapy for depression. It also

provided data to support recent arguments that therapy should help clients to actively use and develop their strengths (Karwoski et al. 2006; Linley and Joseph 2004; Seligman et al. 2006). Interestingly, one of the two past studies which used spirituality to predict depression change (Braam et al. 1997) found that spirituality predicted depression reduction in those who were depressed to begin with, but did not predict depression onset in those who were non-depressed to begin with—this paralleled our findings to some degree. Finally, the last column of Table 4 shows that pre-treatment vulnerabilities made no contribution to the improvement of depression symptoms beyond the role of pre-treatment strengths. Overall, therefore, while initial depression severity was more tied to vulnerabilities, a reduction in depression was related to strengths.

3 General Discussion The purpose of our research was to investigate the relationship between psychological strengths and vulnerabilities and to study the relative roles they play in well-being. We therefore employed two leading measures in the strengths and vulnerabilities literatures— the transcendence scales of the Values In Action Inventory of Strengths (VIA-IS) and the Dysfunctional Attitudes Scale (DAS). In both a normal sample and a clinically depressed sample, the correlations between the strengths and vulnerabilities on these measures were at most moderate. Thus, these strengths and vulnerabilities did not appear to be mere opposites. This finding is especially important for the relatively new field of positive psychology, showing that its contributions are not redundant with the well-established literature on maladaptive characteristics.

Strengths versus Vulnerabilities

87

Zero-order correlations of strengths and vulnerabilities with the well-being variables addressed a number of gaps in the literature. We found that vitality, meaning, and elevating experience were related to all seven transcendence strengths, as well as to each of the measures of cognitive vulnerability. The partial correlations revealed the relative contributions of strengths and vulnerabilities to well-being. Generally, as we had predicted, the strengths had stronger and more consistent unique relationships with positive well-being, while the vulnerabilities had stronger and more consistent unique relationships with ill-being. This suggests that, compared to vulnerabilities, strengths may more directly interact with the mechanisms implicated in positive emotions, while vulnerabilities more directly interact with mechanisms involved in negative emotions. The two psychological and neurological systems that have been identified as underlying positive affect/approach motivation versus negative affect/avoidance motivation (e.g., Davidson and Irwin 1999; Diener and Emmons 1984; Elliot and Thrash 2002) may each be part of even broader complexes: a strengths/positive affect/approach motivation complex, and a vulnerabilities/negative affect/avoidance motivation complex. Further psychological and neurological research will be needed to more fully test this hypothesis. A more specific examination of the partial correlations revealed that, in many cases, strengths and vulnerabilities both had unique relationships with well-being. The vulnerabilities sometimes made incremental contributions to life satisfaction, positive affect, selfesteem, and meaning, while the strengths—namely hope, enthusiasm, humor, and forgiveness—sometimes made incremental contributions to negative affect and depression symptoms. This suggests that the division which exists between the literatures on positive well-being and ill-being is not warranted. While strengths may play the primary role in positive well-being, research on vulnerabilities can make a valuable contribution; similarly, though vulnerabilities play a key role in ill-being, research on strengths is also informative. It is noteworthy, though, that two well-being variables in our data showed unique relationships only with strengths, not vulnerabilities: vitality and elevating experience. The fact that these well-being states distinguished so clearly between strengths and vulnerabilities contributes evidence for their usefulness in well-being research. We also found some interactions between strengths and vulnerabilities, providing further evidence that the combined study of strengths and vulnerabilities is important. There was an interaction for two positive outcomes—self-esteem and meaning—such that vulnerabilities ceased to relate to these outcomes in individuals with high transcendence strengths, and strengths were especially related to these outcomes in individuals with high DAS vulnerabilities. There was also an interaction for the negative outcome of depression, though only in the non-depressed sample. Thus, at least for milder depression symptoms, we found that the relationship between vulnerabilities and depression was reduced, though not eliminated, among people with high strengths; also, the negative relationship between strengths and depression was increased among people with high vulnerabilities. Overall, these findings suggest that strengths may buffer people from the detrimental effects of vulnerabilities, but vulnerabilities do not undermine the beneficial effects of strengths. On the contrary, strengths may be especially beneficial among individuals who are highly vulnerable. Finally, we think that our most striking and revealing finding was the predictive role that strengths played in the improvement of depression symptoms. Three strengths in particular promoted recovery beyond the role played by vulnerabilities: hope, appreciation of beauty and excellence, and spirituality. Our result suggests that strengths may play a substantial role in movement towards recovery. If our finding is replicated in future

research, it will have tremendous implications for clinical practice. Today’s leading therapeutic interventions, cognitive therapy and behavioral therapy, focus primarily on reducing vulnerabilities. Our findings suggest that harnessing strengths can make a significant incremental contribution to recovery. For example, in the early stages of cognitive therapy for depression, clients are guided to engage in regular self-monitoring, with the aim of increasing awareness of their depressive thinking (e.g., ‘‘I’m a failure because I didn’t do this task perfectly’’) and how it affects their mood. Therapists could build upon this framework and have clients take notice of their daily use of strengths as well, and to recognize how these strengths affect their well-being; this could include the use of a checklist of VIA-IS strengths. Further, in the process of what is called cognitive restructuring, cognitive therapists teach clients to collect objective evidence to help them evaluate the validity of their maladaptive beliefs (e.g., ‘‘Do others do this task perfectly?’’). This skill might also be applied to challenge negativistic thinking about strengths (e.g., ‘‘Have others benefited from forgiving someone for this kind of transgression?’’). During the final stages of cognitive therapy, clients begin to identify and challenge maladaptive core beliefs, which represent longstanding patterns of thought and behavior. Typically, depressive core beliefs contain themes of perfectionism and/or need for approval involving the self (e.g., ‘‘I’m defective’’), others (e.g., ‘‘Nobody cares for me’’), and the world (e.g., ‘‘The world is a hostile place’’). Clients are lead to actively seek out evidence which disconfirms these beliefs, and actively generate adaptive alternative beliefs (e.g., ‘‘I have my flaws but overall I’m a good person’’). Clients could actively develop beliefs regarding strengths as well, involving the self (e.g., ‘‘I’m a compassionate, caring person’’), others (e.g., ‘‘Others are worthy of forgiveness, and genuine capable of forgiveness’’), and the world (e.g., ‘‘The world is filled with subtle beauty’’). The research presented here is only an initial step in bringing the literatures on strengths and vulnerabilities closer together. It will be important to extend this research to a more diverse sample than the college population of Study 1, and to disorders other than major depression. Other strengths and vulnerabilities have yet to be compared, such as hardiness (Kobasa 1979) and attributional style (Abramson et al. 1978), and additional well-being outcomes need to be studied, such as physical health and interpersonal functioning. Our present research clearly indicates, however, that strengths and vulnerabilities are not redundant concepts, and that both deserve attention in the literature on well-being and illbeing.
