Optimism and other psychosocial influences on antenatal depression: A systematic review

Antenatal depression is a debilitating experience for many women with significant personal and familial sequelae. Low-income pregnant women living in rural settings are especially vulnerable because of isolation, decreased resources, and stressful living environments. This systematic review summarizes what is known about antenatal depression and synthesizes the evidence regarding the role psychosocial variables could play in the development of safe, effective, and culturally-acceptable non-pharmacological interventions. Searches of the CINAHL, MEDLINE, PSYCHINFO, and ERIC databases, as well as the Cochrane Library, were conducted in September 2010 to identify articles relevant to our topic of study. Psychosocial variables have a significant association with antenatal depression. Optimism has been shown to be inversely correlated with depression, and directly correlated with improved birth outcomes. Optimism is a potentially modifiable variable that could be used to design antenatal prevention and treatment programs. As depression continues to increase in prevalence, and treatment options for pregnant women remain limited, effective interventions must be developed that address the psychosocial variables examined in this review.
