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 erse cultural, political, and social contexts. To address this gap, we used data from the Evidence for Better Lives Study-Foundational Research (EBLS-FR) project to examine the internal consistency reliability, nomological network validity, and cross-country measurement invariance of the nine-item version of the Patient Health Questionnaire (PHQ-9) in antenatal s les 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 erse 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 conceptualizations and manifestations of antenatal depressive symptoms are adequately reflected.

Abstract: Measures that produce valid and reliable antenatal depressive symptom scores in low resource country contexts are important for research efforts to better understand risk factors, outcomes, and effective interventions in these contexts. Establishing the psychometric comparability of scores across countries also facilitates cross-country analysis of similarities and differences across contexts. To date, however, very few studies have evaluated the psychometric properties and comparability of widely used antenatal depressive symptom measures across erse 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 reliability, validity, and cross-country invariance of the 9-item version of the Patient Health Questionnaire (PHQ-9) in antenatal s les across eight low- and middle-income countries (LMICs). We found that the PHQ-9 scores had good internal consistency and construct validity across all eight countries. However, in measurement invariance analyses, only partial metric invariance held and only across four of the countries. Further, there were some notable between-site contrasts in the nomological networks of PHQ-9 scores. Our results suggest that the PHQ-9 yields reliable scores when administered in antenatal populations however, the meaning of the scores varies by country. Thus, interpretation of PHQ scores should consider local meanings of depression to ensure that local conceptualisations and manifestations of antenatal depressive symptoms are adequately reflected.

Abstract: Aims This paper explores the number and characterization of latent classes of adverse childhood experiences across the Evidence for Better Lives Study cohort and investigates how the various typologies link to prenatal substance use (i.e., smoking, alcohol, and illicit drugs) and poor infant outcomes (i.e., infant prematurity and low birth weight). Participants and setting A total of 1,189 mother-infant dyads residing in eight erse low- and middle-income countries (LMICs) were recruited. Methods Latent class analysis using the Bolck, Croon, and Hagenaars (BCH) 3-step method with auxiliary multilevel logistic regressions with distal outcomes were performed. Results The LCA identified three high-risk classes and one low-risk class, namely: (1) highly maltreated (7%, n = 89), (2 ) emotionally and physically abused with intra-familial violence exposure (13%, n = 152), (3), emotionally abused (40%, n = 474), and (4) low household dysfunction and abuse (40%, n = 474). Overall, across all latent classes, there were low probabilities of prenatal substance use and poor infant outcomes. However, pairwise comparisons between classes indicate that class 1 and 3 had higher probabilities of prenatal illicit drug use compared to class 4. Additionally, class 2 had higher probability of low birth weight compared to the three remaining classes. Conclusion The results further our understanding of the dynamic and multifaceted nature of ACEs. More research grounded on LMICs is warranted with more attention to various parameters of risk exposure (i.e., severity, duration, chronicity).
