Abstract
Personality assessment plays a crucial role in various domains in South Africa. Both personality traits and values dimensions have been shown to be reliable predictors of performance and behaviour. Research on personality in South Africa is lacking, as is research on values. Assessment use in South Africa is governed by legislation, requiring evidence of reliability, validity, fairness, and a lack of bias. Most objective, self-report personality assessments are based on the Five Factor Model (FFM), which is widely accepted in personality as being universal. However, evidence on personality in South Africa suggests that there are additional elements to these factors. This study explored the applicability of the Personality and Values Questionnaire (PVQ) for use in the South African context. This was done by investigating internal consistency reliability, construct validity, and aspects of construct bias as they pertain to the potential for adverse impact. A non probability convenience sample of 288 participants completed the PVQ. The study took the form of a non-experimental, cross-sectional design. From the results, it was evident that the scales of the PVQ demonstrated adequate internal consistency reliability. In assessing construct validity, the five factor structure replicated similarly with regards to the Extraversion and Neuroticism domains, but the domains of Agreeableness, Openness, and Conscientiousness loaded differently to that proposed by the FFM and the test developers and more in line with other research on personality in South Africa. Evidence for construct bias was found. Women were likely to be more considerate of others, and concerned with how they appear to others. Black participants appeared more inclined towards harmony in interpersonal relationships and traditionalism. The differences for the language subgroups were small. The results suggest that the PVQ would have some suitability for use in South Africa depending on the context and sample. More research with larger and more diverse samples is needed.
