Mental Health Determinants Among a Psychiatric Outpatient Sample of Vietnamese Migrants in Germany

Cultural immersion, acculturation strategies, and depressive symptoms among first-generation Vietnamese migrants in Germany

BACKGROUND

Worldwide migration represents a major challenge of the 21st century. Despite the strong association between acculturation and mental health, research findings on underlining mechanisms remain inconsistent. Prior research urges to investigate sample characteristics in a more structured manner.

AIMS

The purpose of this study was to systematically investigate factors impacting acculturation and depressive symptoms in a large, not exclusively clinical, sample of Vietnamese migrants in Germany.

METHOD

This study investigated, with multiple regressions, factors (age at arrival, gender, education, religiousness, language skills, residence status, economic status, occupational status, migration motivation, duration of stay, and depressive symptoms) impacting the two dimensions of acculturation, dominant society immersion (DSI) and ethnic society immersion (ESI), in a not exclusively clinical sample (n = 582) of first-generation Vietnamese migrants in Germany. Further, this study examined the relationship between depressive symptoms, DSI and ESI with correlations and acculturation strategies with an ANOVA.

RESULTS

Integration (72.5%) was the most common acculturation strategy, followed by separation (26.8%). In contrast, assimilation (0.5%) and marginalization (0.2%) were very rare acculturation strategies. As predictive factors for DSI lower depressive symptoms scores, male gender, higher education, and better German language skills were found significant. For ESI, less German language skills and older age at arrival were found to be significant. Higher ESI and DSI were correlated to lower depressive symptom scores. Compared to the three other acculturation strategies, integration was linked to the lowest depressive symptoms scores.

CONCLUSIONS

The current study identified crucial factors in the acculturation process, such as depressive symptoms, language skills, education, gender, and age at arrival. Our findings emphasize that immersion into both the dominant and the ethnic culture plays an essential supportive role in the mental health of migrants.

Employment-related mental health outcomes among Australian migrants: A 19-year longitudinal study

BACKGROUND

Migrants experience various stressors at different stages of migration based on their country of origin, ethnic backgrounds, migration context and host country. Employment is one important post-settlement factor associated with mental health among migrant groups. The study investigates whether the country of origin modifies the association between employment and mental health for Australian migrants.

METHODS

Nineteen waves of data from the Household Income and Labour Dynamics in Australia Survey were used. Using fixed-effects regression, we examined the effects of within-person changes in employment status on mental health outcomes as measured by the Mental Health Inventory (MHI-5), controlling for time-varying confounders and stratified by sex and examined effect modification by country of origin.

RESULTS

The relationship between unemployment and mental health was modified by country of origin for men but not women. Unemployed men from Asian (β = -4.85, p < 0.001), African and Middle Eastern (β = -3.61, p < 0.05) countries had lower mental health scores compared to employed Australian-born men. For men, there was evidence of effect modification of the association between employment and mental health by country of origin, with the combined effect of being unemployed and being a migrant from an Asian country was almost three points lower than the summed independent risks of these factors (β = -2.72; p = 0.01). Also, for men, the combined mental health effect of not being in the labour force and coming from a non-English-speaking European country was greater than the summed effects of these factors (β = -2.33; p < 0.001).

CONCLUSION

Tailored employment-support programmes may be beneficial for migrants from ethnic minorities, particularly those from Asian, African and Middle Eastern countries in Australia. Further research is needed to understand why the mental health of migrant men from these countries is particularly vulnerable to unemployment.

Predictors for successful psychotherapy: Does migration status matter?

Background

We investigated, if migration status, and additional sociodemographic and clinical factors, are associated with somatization and depressiveness at admission and with remission after inpatient psychotherapy.

Methods

Multiple linear and binary logistic regression analyses were used to identify predictors for severity of somatoform and depressive symptoms at admission of inpatient psychotherapy (T0), and for remission after inpatient psychotherapy (T1). We tested the association between symptoms concerning somatization (PHQ-15: Patient-Health-Questionnaire Somatization Module) and depression (PHQ-9: Patient-Health-Questionnaire Depression Module) and several sociodemographic and clinical factors in 263 patients at admission. For remission after treatment, we additionally included severity of symptoms at admission, number of diagnoses and duration of treatment in the regression models. Remission after treatment was defined as response plus a post value of less than 10 points in the respective questionnaire. Clinical relevance was interpreted using effect sizes (regression coefficients, Odds Ratio (OR)) and Confidence Intervals (CI).

Findings

Significant and clinically relevant predictors for high symptom severity at T0 were lower education (β = -0.13, p = 0.04), pretreatment(s) (β = 0.205, p = 0.002) and migration status (β = 0.139, p = 0.023) for somatization, and potential clinically relevant predictors (|β|>0.1) for depression were living alone (β = -0.116, p = 0.083), pretreatment(s) (β = 0.118, p = 0.071) and migration status (β = 0.113, p = 0.069). At T1 patients with pretreatment(s) (OR = 0.284 [95% CI: 0.144, 0.560], p<0.001) and multiple diagnoses (OR = 0.678 [95% CI: 0.472, 0.973], p = 0.035) were significantly and clinically relevant less likely to show a remission of depressive symptoms. In addition, a potentially clinically meaningful effect of migration status on remission of depressive symptoms (OR = 0.562 [95% CI: 0.264, 1.198], p = 0.136) cannot be ruled out. For somatoform symptoms pretreatment(s) (OR = 0.403, [95% CI: 0.156, 1.041], p = 0.061) and education (OR = 1.603, [95% CI: 0.670, 3.839], p = 0.289) may be regarded as clinically relevant predictors for remission.

Conclusion

The results of our study suggest that migration status has a clinically relevant influence on severity of somatoform and depressive symptoms at admission. Clinical relevance of migration status can also be assumed regarding the remission of depression. Migration status and further factors affecting the effectiveness of the treatment should be analyzed in future research among larger samples with sufficient power to replicate these findings.
