Multilevel context of depression in two American Indian tribes

Depression is a major debilitating disease. For American Indians living in tribal reservations, who endure disproportionately high levels of stress and poverty often associated with depression, determining the patterns and correlates is key to appropriate clinical assessment and intervention development. Yet little attention has been given to the cultural context of correlates for depression, including the influence of family, cultural traditions or practices, or community conditions.

We used data from a large representative psychiatric epidemiological study among American Indians in 2 reservation communities to estimate nested individual and multilevel models of past-year major depressive episode (MDE) accounting for family, cultural, and community conditions.

We found that models including culturally informed individual-level measures significantly improved the model fit over demographics alone. We found significant community-level variation in the probability of past-year MDE diagnosis in 1 tribe even after accounting for individual-level characteristics.

Accounting for culture, family, and community context will facilitate research, clinician assessment, and treatment of depression in diverse settings.
