Stress, social support, and emotional distress in a community sample of pregnant women.

Emotional distress in women during pregnancy has been shown to increase the risk of adverse outcomes for women and newborns. Increasingly, assessment and management of mood and anxiety problems during pregnancy entail consideration of life stress and interpersonal relationships with partners, friends, and family members. This study describes cross-sectional relations between life stress, perceived social support, and symptoms of depression and anxiety as well as the mediating influence of social support on relations between stress and symptoms. A community sample of women (N = 2,052) provided self-report data during their second trimester of pregnancy. Empirical fit was found for a structural equation model that depicted the combined influences of sociodemographic factors (i.e., socioeconomic status, age, parity), stress (partner conflict and life events), and social support on symptoms of depression and anxiety, chi2 (df 51) = 310.65, p <.05; CFI=.91. Women who reported low levels of social support showed stronger relations between stress and symptoms than women who reported high levels of social support--indicative of a mediating effect of social support. Consistent with previous studies, results suggest that dyadic psychosocial assessment of pregnant women and their partners may facilitate interventions to augment support networks, thereby reducing the risk of emotional distress.
