["Child &Family Social Work, EarlyView. ", "\nABSTRACT\nPrevious research indicates that parental rearing behaviours and the quality of the parent–child relationship significantly influence individual participation in volunteer services. However, such investigations are limited within the Chinese cultural context. This study utilized data from the Digital Society Minor Survey (N = 8321) and employed Stata 15.0 to conduct multiple ordinal regression analysis and bootstrap mediation effect testing. Within the framework of socialization theory, the research systematically explored the effects of parental discipline, parental support and the parent–child relationship on adolescents' participation in volunteer services. In addition, it examined the mediating role of adolescent subjective well‐being in this process. The findings reveal that parental discipline and parental support are positively correlated with adolescents' participation in volunteer services. Moreover, the effect of the parent–child relationship is moderated by educational stage. Specifically, the interaction between the parent–child relationship and educational stage positively influences adolescents' participation in volunteer services. Adolescent subjective well‐being significantly mediates the effects of parental discipline, parental support and the parent–child relationship on the frequency of volunteer service participation.\n"]
