Abstract: "Measures that produce valid and reliable antenatal depressive symptom scores in low resource country contexts are important for efforts to illuminate risk factors, outcomes, and effective interventions in these contexts. Establishing the psychometric comparability of scores across countries also facilitates analyses of similarities and differences across contexts. To date, however, few studies have evaluated the psychometric properties and comparability of the most widely used antenatal depressive symptom measures across diverse cultural, political and social contexts. To address this gap, we used data from the Evidence for Better Lives Study – Foundational Research (EBLS-FR) to examine the internal consistency reliability, nomological network validity, and cross-country measurement invariance of the 9-item version of the Patient Health Questionnaire (PHQ-9) in antenatal samples across eight low- resource contexts. We found that the PHQ-9 scores had good internal consistency across all eight countries. Correlations between PHQ-9 scores and constructs conceptually associated with depression were generally consistent, with a few exceptions. In measurement invariance analyses, only partial metric invariance held and only across four of the countries. Our results suggest that the PHQ-9 yields internally consistent scores when administered in culturally diverse antenatal populations; however, the meaning of the scores may vary. Thus, interpretation of PHQ-9 scores should consider local meanings of symptoms of depression to ensure that context-specific conceptualisations and manifestations of antenatal depressive symptoms are adequately reflected."
