Since SEC has been recognized as a critical component of future talent development, numerous studies have examined the relationship between family emotional expression, parenting behaviors, parent-child interactions, and the development of young children's SEC. Drawing on the theory of mentalizing, this study aims to construct and validate a moderated chain mediation model to investigate the impact of family emotional expression on children's SEC, with a particular focus on the moderating role of parenting stress.MethodA total of 522 families and their children from three rural counties in western China participated in this study. The children's SEC was assessed using the Bayley-III scale, while parents completed the Family Emotional Expression Questionnaire, Parent Impulsivity Questionnaire, Parent Acceptance-Rejection Questionnaire, and Parenting Stress Scale. In order to analyze the mediating and moderating effects, SPSS 27.0 and Process were used for statistical processing.ResultEmotional valence shaped SEC outcomes divergently, with parental impulsivity and acceptance-rejection behaviors sequentially mediating this relationship, particularly in un-left-behind children. Parenting stress mitigated negative emotions' effects on impulsivity while moderating mediation strength. Left-behind families exhibited cultural adaptation through suppressed negative emotional expression, contrasting with un-left-behind dynamics.ConclusionThese findings underscore the critical role of fostering a positive family emotional climate in promoting children's SEC development. From the perspective of ecosystem theory, parents should provide a good family environment for preschool children, so as to improve their emotional awareness and emotional expression, and ultimately improve their socio-emotional ability.
