A model of maternal postpartum depression was tested in which difficult infant temperament was construed as a stressor and supportive interpersonal relationships were construed as a protective resource. It was hypothesized that both infant temperamental difficulty and level of social support would affect maternal depression through the cognitive mediation of perceived self-efficacy in the parenting role. Participants were 55 married women who were assessed during pregnancy and again 3 months postpartum. Infant temperament was assessed through observation, maternal crying records, and the Revised Infant Temperament Questionnaire. Results of a path analysis indicated that infant temperamental difficulty was strongly related to the mothers' level of postpartum depression, both directly and through the mediation of parenting self-efficacy. Consistent with predictions, social support appeared to exert its protective function against depression primarily through the mediation of self-efficacy. Both practical implications for identifying women at risk for postpartum depression and theoretical implications for understanding the mechanisms through which stressful events and social support affect adjustment are discussed.

This study examined the extent to which childbearing increases vulnerability to clinical depression and depressive symptomatology among primiparous adolescent girls (ages 14 to 18). Childbearing Ss (n = 128) were assessed during pregnancy, 6 weeks postpartum, and 1 year postpartum. Matched nonchildbearing Ss (n = 114) were assessed at corresponding time points. Six weeks postpartum, 6% of the childbearing adolescents met Research Diagnostic Criteria for major depression and 20% for minor depression. These rates were not significantly different from those found for nonchildbearing Ss (4% major depression, 10% minor depression). However, higher rates of somatic symptoms of depression were found among the childbearing Ss than among the nonchildbearing Ss.

Maternal parenting self-efficacy (PSE) is a potential target for infant mental health interventions because it is associated with a number of positive outcomes for children and mothers. Understanding the development of maternal PSE under conditions of increased parenting stress, such as parenting an infant who is easily distressed and difficult to soothe, will contribute to providing more effective interventions. This study examines the development of maternal PSE in mothers of infants with high negative emotionality (NE). The Neonatal Behavioral Assessment Scale (NBAS; T. Brazelton, 1973) was administered twice to 111 infants to select a sample of irritable (n = 24) and nonirritable (n = 29) infants for a prospective study comparing the development of PSE in mothers of infants differing in neonatal NE. Consistent with our hypotheses and previous research, at 8 weeks’ postpartum, mothers of irritable infants have significantly lower domain-specific PSE than do mothers of nonirritable infants. Contrary to our predictions, mothers of irritable infants exhibit a significant increase in domain-specific and domain-general PSE from 8 to 16 weeks’ postpartum. The implications of these results for infant mental health screening, infant mental health interventions, and research on self-efficacy theory are discussed.
