| Summary: | Assessments are regularly used among clinicians within psychology, yet many are deemed too time-consuming and expensive. The Personality Inventory for— Diagnostic and Statistical Manual of Mental Disorders (5th ed.; 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 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 International Neuropsychiatric Interview’s (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.
