This study examined sex differences in domain and facet scores from six personality tests in various large adult samples. The aim was to document differences in large adult groups which might contribute new data to this highly contentious area. We reported on sex differences on the Myers-Briggs Type Indicator (MBTI); the Five Factor NEO-PI-R; the Hogan Personality Indicator (HPI); the Motives and Values Preferences Indicator (MVPI); the Hogan Development Survey (HDS) and the High Potential Trait Indicator (HPTI). Using multivariate ANOVAs we found that whilst there were many significant differences on these scores, which replicated other studies, the Cohen’s d statistic showed very few (3 out of 130) differences >.50. Results from each test were compared and contrasted, particularly where they are measuring the same trait construct. Implications and limitations for researchers interested in assessment and selection are discussed.
