Objectives: This study considers the direct effects of familial support, social participation, and psychological well-being on the parenting efficacy of Vietnamese married immigrant women in rural South Korea. It also examines the indirect effects of social participation and psychological wellbeing, which mediate familial support and parenting efficacy. Methods: Questionnaires were administered to 198 married immigrant women from Vietnam who resided in rural communities across 20 cities in 9 provinces of South Korea, and data were analyzed to examine sequential mediation effects among variables using PROCESS MACRO methods. Results: Firstly, familial support had significant direct effects on parenting efficacy. Secondly, familial support indirectly affected parenting efficacy by mediating psychological well-being and yielding sequential mediation effects on social participation and psychological well-being. Conclusion: These findings indicate that it is necessary to adopt an integrated approach when analyzing the parenting efficacy of specific communities that considers personal psychological variables, familial relationships, and social relationships; this will lead to a more comprehensive understanding of and implications for the parenting efficacy of Vietnamese married immigrant women, who comprise the majority of rural residents.Keywords : married immigrant women, familial support, social participation, psychological wellbeing, parenting efficacy 1 , 2 , 3 ORCID In Ok Park
