Abstract
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.

One of the cruxes of psychologists is formulating diagnoses to enable the application of effective treatment
The objectives of this study were to examine the construct validity, as well as convergent and discriminant validity of the measuring instrument compared with similar constructs of the NEO Personality Inventory Revised (NEO-PI-R) and the Mini International Neuropsychiatric Interview’s (MINI) Subscale K: Psychotic disorders and mood disorder with psychotic features
For each NEO-PI-R factor, for example, Neuroticism, it was estimated as a single factor with the PID-5-BF represented by its individual components
Summary
One of the cruxes of psychologists is formulating diagnoses to enable the application of effective treatment. Much like the DSM5, the ICD-10 provides health care professionals with a framework regarding the organization and decision-making of health care services, as well as an administrative structure for reimbursement and claims for billing, tracking, and outcome assessment (Bach & First, 2018; Keeley et al, 2016; Reed, 2010). Psychometric assessments are important tools as a further aid in making correct diagnoses. These assessments need to be of high quality and standardized within a South African context to yield valid and reliable results (Foxcroft et al, 2004; Foxcroft & Roodt, 2009)
