- ItemCommon mental disorders in Peruvian immigrant in Chile: a comparison with the host population(BMC, 2023) Errazuriz, Antonia; Schmidt, Kristin; Valenzuela, Paulina; Pino, Rodolfo; Jones, Peter B. B.BackgroundThe Inner Santiago Health Study (ISHS) aimed to (i) estimate the prevalence of common mental disorders (CMD; i.e. depressive and anxiety disorders) among immigrants of Peruvian origin in Chile; (ii) determine whether such immigrants are at higher risk of CMD when compared with the native-born geographically matched population (i.e. non-immigrants); and (iii) identify factors associated with higher risk of any CMD among this immigrant group. A secondary aim was to describe access to mental health services by Peruvian immigrants meeting criteria for any CMD.MethodsFindings are based on a population-based cross-sectional household mental health survey of 608 immigrant and 656 non-immigrant adults (18-64 years) residing in Santiago de Chile. Diagnoses of ICD-10 depressive and anxiety disorders and of any CMD were obtained using the Revised Clinical Interview Schedule. The relationships between demographic, economic, psychosocial, and migration-specific predictor variables, and risk of any CMD were analyzed with a series of stepwise multivariate logistic regression models.ResultsThe one-week prevalence of any CMD was 29.1% (95% CI: 25.2-33.1) among immigrants and 34.7% (95% CI: 30.7-38.7) among non-immigrants. Depending on the statistical model used in the pooled sample, we found the prevalence of any CMD among non-immigrants to be higher (OR=1.53; 95% CI: 1.05-2.25) or similar (OR=1.34; 95% CI: 0.94-19.2) when compared with immigrants. In the multivariate stepwise regression of any CMD in immigrants only, the prevalence was higher for females, those with primary compared to higher education, in debt and exposed to discrimination. Conversely, higher levels of functional social support, sense of comprehensibility, and manageability were associated with a lower risk of any CMD in immigrants. In addition, no differences were observed between immigrants and non-immigrants reporting any CMD in mental health service utilization.ConclusionOur results evidence high levels of current CMD in this immigrant group, particularly amongst women. However, lower adjusted prevalence of any CMD in immigrants compared to non-immigrants was limited to preliminary statistical models, thus failing to provide clear support for a "healthy immigrant effect". The study sheds new light on differences in CMD prevalence by immigrant status in Latin America by examining differential exposure to risk factors in immigrant versus non-immigrant groups.
- ItemThe Validity and Reliability of the PHQ-9 and PHQ-2 on Screening for Major Depression in Spanish Speaking Immigrants in Chile: A Cross-Sectional Study(MDPI, 2022) Errazuriz, Antonia; Beltran, Rodrigo; Torres, Rafael; Passi Solar, AlvaroBackground: The study aimed to explore the psychometric properties of two versions of the Patient Health Questionnaires (PHQ-9 and PHQ-2) on screening for Major Depressive Disorder (MDD) among Spanish-speaking Latin American adult immigrants in Santiago, and to explore factors associated with a higher risk of occurrence of MDD among them. Methods: A representative sample of 897 Spanish-speaking immigrants completed the PHQ-9. The Composite International Diagnostic Interview (CIDI) was employed to evaluate MDD. Internal consistency and structural validity were evaluated using Cronbach's oc coefficient and confirmatory factor analysis (CFA). Convergent validity with the 7-item General Anxiety Disorder Scale (GAD-7) was assessed using Spearman's correlations. Sensitivity, specificity, positive predictive values, and area under the receiver operating characteristic (ROC) curve were calculated for different cut-off points. Logistic regression analysis was used to identify factors associated with the risk of MDD. Results: Cronbach's oc coefficient of the PHQ-9 was 0.90; item-total correlation coefficients ranged from 0.61 to 0.76 and correlation with the GAD-7 was moderate (r = 0.625; p < 0.001). CFA on three alternative models suggests a plausible fit in the overall sample and among two of the subsamples: Peruvians and Venezuelans. Taking the results of CIDI as the gold standard for MDD, the area under the ROC curve was 0.91 (95% confidence interval (CI): 0.83-1.0). When the cut-off score was equal to 5, values of sensitivity, specificity, and Youden's index were 0.85, 0.90, and 0.75, respectively. Multivariate logistic regression analyses showed that the influence of having three or more children (OR = 3.91, 95% CI: 1.20-12.81; p < 0.05), residency in Chile of up to three years (OR = 1.79, 95% CI: 1.07-3.00; p < 0.05), active debt (OR = 2.74, 95% CI: 1.60-4.70; p < 0.001), a one (OR = 2.01, 95% CI: 1.03-3.94; p < 0.05) and two or more events of adversity during childhood (OR = 5.25, 95% CI: 1.93-14.3; p < 0.01) on the occurrence of MDD was statistically significant. Reliability (a = 0.62), convergent (r = 0.534; p < 0.01) and criterion (AUC = 0.85, 95% CI: 0.67-1.00) validity coefficients of the PHQ-2 were weaker than for the PHQ-9. Conclusions: The PHQ-2 and the PHQ-9 are reliable and valid instruments for use as screeners for MDD among Spanish-speaking populations of Latin America.
