Stress and social support as predictors of anxiety and depression during pregnancy.

Four groups, 153 high-risk women, 75 high-risk mates, 218 low-risk women, and 147 low-risk mates, were studied during the 24th to 34th weeks of pregnancy. Hierarchical regression analysis was used to study the effect of stress, social support (perceived, received, and network size), self-esteem, and mastery on anxiety and depression. These variables predicted 26.25% of anxiety among low-risk women, 44.70% among low-risk mates, 10.04% among high-risk women, and 16.00% among high-risk mates. Prediction of depression was better for all groups except high-risk mates (15.50%); 31.93% of the variance in low-risk women's depression was predicted, with 51.91% for low-risk mates and 29.63% for high-risk women. Neither received support nor network size entered the regression models for any of the groups.
