The structure of self-reported behaviour and its relations with SNAP-2 personality scales

Abstract

This study investigates the structure of self reported daily behaviours and their relations to personality traits measured by SNAP-2 in a sample consisting of university students and community dwelling adults, as well as in a psychiatric patient sample. In addition, the behaviour structure is studied separately in participants who score low or high on SNAP personality disorder scales. The results suggests that individual behavioural items form relatively coherent scales that are related to negative emotion expression, socializing, assertive behaviours, rule following, and avoidance behaviours. These scales show somewhat differential correlation patterns with SNAP trait and temperament scales. While behaviour reports in this study add no additional value to personality scales in predicting patient status, they are strongly related to predicting high scorers on personality disorder scales.
