Conceptualizing depression in Vietnam: Primary health care providers' explanatory models of depression.

The purpose of this qualitative study was to elicit the explanatory models (EMs) of primary healthcare providers (PHPs) in Vietnam in order to (a) understand if and how the concept of depression is understood in Vietnam from the perspective of nonspecialist providers and community members, and (b) to inform the process of introducing services for depression in primary care in Vietnam. We conducted semistructured interviews with 30 PHPs in one rural and one urban district of Hanoi, Vietnam in 2014. We found that although PHPs possess low levels of formal knowledge about depression, they provide consistent accounts of its symptoms and aetiology among their patient population, suggesting that depression is a relevant concept in Vietnam. PHPs describe a predominantly psychosocial understanding of depression, with little mention of either affective symptoms or neurological aetiology. This implies that, with enhanced training, psychosocial approaches to depression care would be appropriate and acceptable in this context. Distinctions were identified between rural and urban populations in both understandings of depression and help-seeking, suggesting that enhanced services should account for the diversity of the Vietnamese context. Alcohol misuse among men emerged as a considerable concern, both in relation to depression and as stand-alone issue facing Vietnamese communities, indicating the need for further research in this area. Low help-seeking for depression in primary care implies the need for enhanced community outreach. The results of this study demonstrate the value of eliciting EMs to inform planning for enhanced mental health service delivery in a global context.
