Objective: The purpose of this study was to examine the psychometric properties of the multi-dimensional Psychological Ownership Questionnaire when applied in an organisational context. Method: A cross-sectional survey research design was employed (N = 953) to investigate the factorial validity, internal consistency, measurement invariance, and concurrent validity of the instrument. Results: The results showed that the five-dimensional factor structure of the Psychological Ownership Questionnaire could be confirmed. No configural, scalar, and metric invariances among different age cohorts were shown. The instrument showed reliability at both a lower (Cronbach's alpha) and upper (composite reliability) limit level. In relating the instrument to turnover intention, its concurrent validity was established. Conclusion: The Psychological Ownership Questionnaire seem to be a useful, valid, and reliable self-report questionnaire for the assessment of psychological ownership within a South African organisational context.
