ASSESSING THE BIG FIVE: DEVELOPMENT AND VALIDATION OF THE OPENNESS CONSCIENTIOUSNESS EXTRAVERSION AGREEABLENESS NEUROTICISM INDEX CONDENSED (OCEANIC) RALF SCHULZE & RICHARD D. ROBERTS A BSTRACT. A new measure of the Big Five personality constructs, the Openness Conscientiousness Extraversion Agreeableness Neuroticism Index Condensed (OCEANIC), was developed and validated. In Study 1 (N = 166), the convergent validity with the Big Five as assessed by the NEO-FFI was established. Study 2 (N = 3 808) served to investigate the structure of the instrument with stepwise exploratory factor analysis and confirmatory factor analysis. The incremental predictive validity with respect to objective university grades was examined in Study 3 (N = 145). The results show that a) the scales of the initial item pool converge with those of an established measure of the Big Five, b) the Big Five factor model fits the data both at the item and facet level and both for subsamples of students and workers, and c) consistent with previous research, the Conscientiousness factor of the OCEANIC predicts university grades beyond intelligence measures.
