The study aimed to examine the psychometric properties of the MHC-SF within selected organisational contexts. Specifically, the aim was to determine the factorial validity, measurement invariance, and reliability of the instrument for South African organisations. A cross-sectional online survey-based research design was employed, coupled with a convenience sampling strategy (N = 624). The results showed that the original three-dimensional factor structure of the MHC-SF fitted the data the best. Items loaded statistically significantly on all three subscales (emotional, psychological, social wellbeing). Further, the scale showed full configure, convergent and metric invariance between males and females. However, invariance was not established in either age cohorts, language groups, or marital status. The instrument proved to be reliable at both a lower (Cronbach Alpha) and upper level (Composite reliability) limit within South African organisational contexts.
