Abstract:
This study examined the latent factor structure of the General Health Questionnaire-28 (GHQ-28) in a Black South African sample (N = 523). Results of the single-group confirmatory factor analysis support the universal four-factor structure of general psychological health observed in Western samples. However, multigroup confirmatory factor analyses (i.e. split-sample cross-validation approach, conducted with invariance analyses) for a three-factor structure suggest that psychological health could have a less differentiated dimensional structure in some African populations. Theoretical and practical implications of the study results are discussed.
