Two occupational health surveillance cohorts (<i>N</i> = 730 and <i>N</i> = 128) representing diverse occupational fields completed the GHQ-12 together with validated measures of common mental disorders, psychological resilience, emotional wellbeing and mental toughness. Confirmatory factor analyses supported a bifactor model comprising a strong general factor with minimal unique variance attributable to the positive and negative item subfactors. Internal consistency was high across samples. The GHQ-12 total scores correlated positively with depression, anxiety and adjustment disorder symptoms, and negatively with psychological resilience, emotional wellbeing and mental toughness, supporting convergent validity. Test-retest reliability was moderately strong, with a minority showing marked deterioration of mental health under more stressful operational conditions, indicating the tool's potential sensitivity to environmental stressors. The GHQ-12 total scores differentiated between individuals with and without common mental disorders, and receiver operating characteristic analyses indicated acceptable sensitivity and specificity at optimal thresholds. Introducing a 'grey-zone' approach with lower and upper thresholds enhanced its practical application for surveillance and triage, by improving risk identification and decision-making for occupational health practitioners.</p><p><strong>Contribution: </strong>This study provides the first large-scale evaluation of the GHQ-12 in ICUE occupational environments in southern Africa.

Without such a measure, competence on this construct cannot be assessed, nor can the effectiveness of interventions designed to enhance compassion be determined. The aim of this study was to develop and validate a self-assessment measure of medical practitioner compassion competence (the Medical Practitioner Compassion Competency Questionnaire [MPCCQ]). The MPCCQ was administered to a sample of 234 medical practitioners in South Africa. They represented three healthcare system levels, namely, the primary level (healthcare centres and clinics), the secondary level (district and regional hospitals) and the tertiary level (central, specialised and sub-specialist hospitals). The quantitative data were analysed with statistical packages, namely, Statistical Package for the Social Sciences (SPSS) version 25 and LISREL 8.8, and structural equation modelling was used to fit the MPCCQ measurement model and structural model. Dimensionality and item analyses returned generally positive results. Fit statistics and criteria used to judge the fit of the models included Chi-square (χ²), goodness of fit index (GFI), adjusted goodness of fit index (AGFI), root mean square error of approximation (RMSEA), root mean square residual (RMR) and the standardised root mean square residual (SRMR).

This study examines the factor structure of the PHQ-9 among South African first responders using exploratory factor analysis (EFA), confirmatory factor analysis (CFA) with ancillary bifactor indices, parallel analysis and Mokken analysis. A cross-sectional study design was used with data collected from police officers (<i>n</i> = 309) and paramedics (<i>n</i> =120). Although the EFA identified a two-factor structure, this was not supported by the other analyses.

Ancillary bifactor and parallel analysis also did not support the interpretation of the PHQ-9 as multidimensional. Lastly, Mokken scale analysis confirmed that the PHQ-9 is a strong and reliable unidimensional scale of depression. These findings suggest that the PHQ-9 predominantly measures a single construct of depression, consistent with the unidimensional view of the disorder.</p><p><strong>Contribution: </strong>The present study provides evidence from different measurement perspectives that the commonly used PHQ-9 measures a single construct of depression and not two separate components as some studies suggested.
