The purpose of the South African Personality Inventory (SAPI) project is to develop a personality measure that can be used within the South African context and that can account for the diversity that exists within the South Africa. This study is intended at validating the Conscientiousness scale of the SAPI as well as considering how well the measure replicated across language groups (Germanic, Nguni and Sotho) in South Africa. The data utilised in this study was collected from working individuals from a number of different organisations in South Africa (N = 890). The Conscientiousness scale consists of 36 items that yielded a five factor structure namely, Dedication, Discipline, Commitment, Orderliness, Organised. It was found that the Conscientiousness scale is a valid and reliable measure of the personality trait Conscientiousness scale. The results indicated that the general factor, Conscientiousness replicated well across the different language groups in South Africa, but the five factor solution did not yield conclusive results. Furthermore, the results of the Differential Test Functioning (DTF) analysis revealed that the scale had a significant effect size and upon further investigation it was shown that two of the items that had significant Differential Item Functioning (DIF) effect sizes could be removed in order to obtain a non-bias measure of Conscientiousness on the SAPI.
