Abstract
The present study uses a prospective longitudinal study design to investigate the development of maternal self-efficacy in the transition phase to parenthood, drawing on a large sample of socially and/or culturally disadvantaged families (N = 292). Parity, maternal education, migration, informal and formal social support are considered as potential predictors. Results indicate that previous birth experience, being born abroad, and higher levels of formal and informal social support during pregnancy jointly predict higher levels of maternal self-efficacy three months after birth. First-time mothers and mothers born in Germany (where the study was conducted) benefit more from formal support than mothers with previous experience and mothers born outside of Germany. Overall, maternal self-efficacy increases significantly. Implications for prenatal maternal care are discussed.
