PTSD and timing of trauma exposure in shaping the HPA-axis profile in depression

Abstract

Drawing upon Berry’s (1980) bi-dimensional model of acculturation and using data from a community-based sample of adults in Miami-Dade, Florida, the current investigation compared various immigrant acculturation profiles in their levels of depressive symptoms and assessed the mediating role of social support in explaining mental health differences across these acculturation profiles. Latent class analysis specified separated, partial separated, bicultural and marginal profiles of acculturation among Latino immigrants. Notably, our findings identified a small, albeit significant, marginal class among Latino immigrants, and both bivariate and multivariate findings demonstrated that those in marginal class reported the poorest mental health. Our findings further revealed that the observed mental health disadvantage among the marginal class relative to other immigrants was due to their disadvantage in family support . Overall, this investigation further underscores the importance of family support as an element of immigrant acculturation experience and mental health. From a policy perspective, social support, specifically family support, is critical for immigrant mental health, and a lack of family support may increase the risk for developing a marginal experience and mental health problems among a growing population of Latino immigrants in the United States.
