Despite the importance that is attributed to coping as a factor in psychological and somatic health outcomes, little is known about actual coping processes, the variables that influence them, and their relation to the outcomes of the stressful encounters people experience in their day-to-day lives. This study uses an intraindividual analysis of the interrelations among primary appraisal (what was at stake in the encounter), secondary appraisal (coping options), eight forms of problem- and emotion-focused coping, and encounter outcomes in a sample of community-residing adults. Coping was strongly related to cognitive appraisal; the forms of coping that were used varied depending on what was at stake and the options for coping. Coping was also differentially related to satisfactory and unsatisfactory encounter outcomes. The findings clarify the functional relations among appraisal and coping variables and the outcomes of stressful encounters.

Prenatal psychosocial predictors of infant birth weight and length of gestation were investigated in a prospective study of 120 Hispanic and 110 White pregnant women. Hypotheses specifying that personal resources (mastery, self-esteem, optimism), prenatal stress (state and pregnancy anxiety), and sociocultural factors (income, education, ethnicity) would have different effects on birth outcomes were tested using structural equation modeling. Results confirmed that women with stronger resources had higher birth weight babies ((3 = .21), whereas those reporting more stress had shorter gestations (|3 =-.20). Resources were also associated with lower stress ((3 =-.67), being married, being White, having higher income and education, and giving birth for the first time. There was no evidence that resources buffered the effects of stress. The importance of personal resources in pregnancy is highlighted along with implications for understanding the etiology of adverse birth outcomes.

This prospective study examined the effects of prenatal social support on maternal and infant health and well-being in a sample of low-income pregnant women (N = 129). Three aspects of support (amount received, quality of support received, and network resources) and four outcomes (birth weight, Apgar scores, labor progress, and postpartum depression) were studied. Results indicated that women who received more support had better labor progress and babies with higher Apgar scores. Women with higher quality support had babies with higher Apgar scores and experienced less postpartum depression. Also, women with larger networks had babies of higher birth weight. Further analyses indicated that the outcomes as a whole were more consistently predicted by instrumental rather than emotional forms of support. Finally, although there was some evidence for stress-buffering eifects of support, the overall findings were more consistent with a main effect model.

Independent of biomedical risk, maternal prenatal stress factors are significantly associated with infant birth weight and with gestational age at birth.

As pregnancy advances, women become decreasingly sensitive to the effects of stress. This decrease in vulnerability may reflect increasing protection of the mother and fetus from adverse influences during pregnancy.
