Self-leadership has been recognised as a fundamental competency for effective learning and job performance. The primary goal of this study was to validate the Abbreviated Self-leadership Questionnaire on a South African sample. Numerous questionnaires have been developed to measure self-leadership, with the Revised Self-leadership Questionnaire being the most widely used questionnaire. However, the Revised Self-leadership Questionnaire has been deemed too long; hence, the authors abbreviated the measure. Therefore, there is a need to assess the reliability and construct validity of the abbreviated Self-leadership Questionnaire on a South African sample. A non-probability sample consisting of 400 students drawn from a university in the Western Cape was used. The reliability of the Abbreviated Self-leadership Questionnaire was evaluated using SPSS, while construct validity was assessed via confirmatory factory analyses in the LISREL program. Moderate levels of reliability were found for the subscales of the Abbreviated Self-leadership Questionnaire. Reasonable model fit with the data was found for the first-order measurement model. The study contributes to the requirements of the Amended Employment Equity Act of South Africa (Republic of South Africa, 1998) which promotes the use of reliable and valid instruments in South Africa by confirming the psychometric properties of the Abbreviated Self-leadership Questionnaire.
