Introduction 

The personality construct of Machiavellianism captures a tendency to exploit, deceive, and distrust



others (Christie & Geis, 1970) 

Research has been inconsistent regarding Christie and Geis’ (1970) assumption that Machiavellians



must be free of psychopathology

Individuals who are higher in Machiavellianism tend to engage in interpersonal exploitation (tactics



The inconsistent relationship between Machiavellianism and psychopathology may be due to treating Machiavellianism as unitary, despite evidence of multidimensionality (Rauthmann & Will, 2011)

Psychopathology could result from their antisocial behaviours, rejection and alienation from peers,

dimension), hold a cynical view of human nature (views dimension), and lack the conventional morality

cynical view of humanity, and overestimation of interpersonal threat (e.g., McHoskey, 2001; Wilson,

that would condemn their actions (morality dimension)

Near, & Miller, 1998)



In the absence of clear and consistent dimensions, factor analytic studies tend to differentiate Machiavellian views from tactics regardless of the factor solution (Fehr, Samsom, & Paulhus, 1992)

Aims AIM 1: To develop a psychometrically sound multidimensional version of the Mach-IV (the most commonly employed measure of Machiavellianism)

AIM 2: To investigate whether psychopathology is associated with perpetrating exploitative behaviours and holding a cynical view of others

1. Scale Development I: Analysis of Items and Structure

2. The Relationship with Psychopathology



First, we developed a psychometrically sound multidimensional measure of Machiavellianism using a sample of US undergraduate students (N = 1,478)



Confirmatory factor analysis (CFA) showed the Mach-IV factor structure (tactics, views, and morality) was poorly specified and could not be appropriately estimated because of a non-positive definite matrix







We identified six key psychopathology domains from the literature: depression, fear, anxiety, impulsivity, externalising psychopathology, and thought dysfunction (Kotov et al., 2011; Krueger & Markon, 2006)



Structural equation modelling (SEM) was used to test the relationship between the latent psychopathological domains and Machiavellian views and tactics. Manifest

Item analysis compared each item’s corrected item-total correlation with its subscale to its correlation with the other two subscales and only retained items that

indicators were created from scales that have been widely used in both research and clinical practice, such as the Minnesota Multiphasic Personality Inventory-2-RF,

discriminated between the subscales and strongly correlated with the Mach-IV. We retained four tactics items (α = .70) and six views items (α = .61)

Beck’s Depression Inventory – II, and the Barratt Impulsivity Scale –11 (see figure below) 

The final scale was called the Multidimensional Mach-IV (MDM-IV) (α = .66) and

of Machiavellian tactics, predicts all areas of psychopathology (see Table 1 below)

correlated strongly with the Mach-IV (r = .90) 

Findings indicated that holding Machiavellian views, even when controlling for effects



CFA showed that the MDM-IV’s two factor structure fitted the data well (see right)

Machiavellian tactics predicted externalising psychopathology and impulsivity

Machiavellianism consists of two dimensions, namely Machiavellian views and tactics

A longitudinal CFA indicated that there were equivalent factor loadings over time, CFI = .008, RMSEA = .002, and estimates of temporal stability between the latent variables

Machiavellianism is best viewed as a two-dimensional construct consisting of views and tactics

The MDM-IV captures the multidimensional structure of Machiavellianism

Conclusions

Above: A structural equation model (SEM) of Machiavellian views and tactics predicting an endogenous psychopathology construct. Ellipses represent latent factors and rectangles represent manifest indicators. n = the number of manifest indicators for the psychopathology construct. All measurement and structural models had good fit.



The 10-item MDM-IV scale replicated the Mach-IV, was temporarily stable, and discriminated between both dimensions of Machiavellianism



Machiavellian views and tactics significantly predicted major psychopathological constructs, contradicting original assumptions. Holding Machiavellian views was highly conducive to psychopathology, whereas employing Machiavellian tactics was, although to a lesser degree, related to externalising disorders

Individuals holding Machiavellian views are not free of psychopathology, but manipulate others amidst all dimensions of psychological distress
