Psychometric properties of the PID-5-BF in an undergraduate sample of South African university students

Abstract

Assessments are regularly used amongst clinicians within Psychology, yet many are deemed too time-consuming and expensive. The Personality Inventory for DSM-5 Brief Form (PID-5-BF) was developed to measure maladaptive personality traits (Negative Affect, Detachment, Antagonism, Disinhibition, and Psychoticism), based on the "hybrid model" for personality disorders included in the DSM 5 Section III. Literature indicates that reliability and validity for the PID-5-BF has been established in other countries. We explored these psychometric properties within a South African population using the NEO Personality Inventory Revised and MINI Subscale K: Psychotic disorders and mood disorder with psychotic features, as measures for comparison. Our results indicated support for the PID-5-BF with sufficient reliability, convergent and discriminant validity. More research is needed on the PID-5-BF, especially in South Africa, but our findings indicate it to be a promising assessment tool that could greatly benefit clinicians in the mental health sector.
