Comparison of the relations between three dimensional personality frameworks and intra- and inter-personal functioning

Abstract

We aimed to understand which of the three personality frameworks including Criterion B of the DSM-5 model, Five-Factor Model (FFM), and affective temperaments was most overlapping with both intrapersonal and interpersonal dysfunctions (Criterion A). This cross-sectional study consisted of N = 496 people from western Iran. Pearson correlation and regression techniques were used for data analysis. Although all dimensional personality frameworks were related to both personality dysfunctions, Criterion B was a stronger predictor above and beyond the other frameworks. Our findings do not support the replacement of Criterion B by traditional personality and temperament constructs. The significant incremental validity of both the FFM and affective temperaments beyond the DSM-5 model addresses potential complementary constructs to enhance Criterion B to explain Criterion A.
