Psychometric Properties of the Personality Inventory for DSM-5 Brief Form in an Undergraduate Sample of South African University Students

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.

Automated summary

Assessments are widely used in psychology among clinicians, with PID-5-BF developed to measure maladaptive personality traits. Reliability and validity have been established in other countries, with South African research confirming its effectiveness. Further research is needed in South Africa, but PID-5-BF shows promise as an assessment tool for mental health clinicians.
