The objective of this study is to examine the construct validity of the Openness scale in the South African Personality Inventory (SAPI). The SAPI project aims to develop a personality questionnaire that is applicable in the multicultural South African context. A total of 891 students and working adults, of different race groups (White, Black, Indian and Coloured), with a minimum of Grade 12 or equivalent and speaking eleven different languages participated in the study. A cross sectional design was used to collect data using paper and pencil questionnaires administered in English. The Openness scale consisted of 23 items. A hierarchical Schmid-Leiman factor solution was used to investigate if a strong general Openness factor could be retrieved from participants’ responses. Tucker’s phi coefficient was used to determine factor congruence across language groups. The results suggest that more work is needed to improve validity and reliability of the current SAPI Openness scale, as it failed to produce a general Openness factor. Results show that it is difficult to attach meaningful psychological interpretations to scores on the Openness scale can be made.
