The South African Personality Inventory (SAPI) was developed with the aim of producing a personality measurement that is valid, reliable, fair, and unbiased, as required by the South African legislation. The Relationship Harmony cluster is one of the nine identified personality clusters in the SAPI. The objectives of this study were to investigate the construct validity of the Relationship Harmony cluster by (1) exploring the factor structure of the preliminary developed Relationship Harmony Scale, (2) determining whether the Relationship Harmony Scale can be correlated with or distinguished from the popular Five Factor Model (FFM) factors, and (3) determining whether the Relationship Harmony cluster can act as a valid predictor for Prosociality. A Relationship Harmony questionnaire developed for the South African Personality Inventory (SAPI), the shortened version of the Basic Traits Inventory (BTI-S), and the Prosocialness Scale were utilised. The sample consisted of (N=435) students from tertiary institutions within the Gauteng and North-West provinces of South Africa. The results indicate that the Relationship Harmony measuring instrument represents five reliable factors. Furthermore, the results suggest that Agreeableness from the FFM and the Relationship Harmony cluster converge. Lastly, Relationship Harmony proved to be a valid predictor of Prosociality with three factors of the Relationship Harmony Scale playing an important role in predicting Prosociality.
