For new mothers, coping with infant distress is challenging. Mothers' self-efficacy in emotion-related parenting plays critical roles in shaping their adaptation and children's development. Research on antecedents of maternal parenting self-efficacy has been predominantly based on the global self-efficacy theory outlined by Bandura in the 1970s. Despite the utility of Bandura's theory, subsequent research on emotion-related parenting has highlighted avenues for extending and adapting his model to more adequately elucidate the cognitive, affective, and behavioral processes underlying the development of maternal emotion-related parenting self-efficacy. In view of the basic and applied value of a clearer account of how new mothers' emotion-related parenting self-efficacy emerges and evolves, the increasing amount of research on this topic, and the absence of syntheses of extant studies, we reviewed relevant literature. First, constructs and propositions in prevailing theoretical perspectives are examined for their utility to elucidate the development of new mothers' emotion-related parenting self-efficacy, particularly the implicated cognitive, affective, and behavioral mechanisms and how they work together. Second, a framework is outlined that integrates strengths of various theories to delineate processes underlying the emergence and evolution of new mothers' emotion-related parenting self-efficacy. Third, findings across disparate studies are summarized to provide a foundation for the offered framework. To better inform future research, we demonstrated how to build testable mid-range models with substantive constructs and hypotheses from the proposed framework through deductive theorizing process. We also evaluated the utility of the proposed model for studying new fathers. Last, implications for future research and practice are discussed.
