ABSTRACT This study examined the unique and interaction effects of adult attachment and filial piety among Chinese young adults on three selected interpersonal functioning variables (i.e. social self-efficacy, constructive conflict resolution, and interpersonal difficulties). Findings from a sample of 231 university students recruited from Beijing, China indicated that both attachment avoidance and anxiety were negatively associated with social self-efficacy and constructive conflict resolution and positively associated with interpersonal problems. Reciprocal filial piety was found to not only contribute to significant increment above and beyond what was explained by adult attachment variables but also be a significant moderator for the attachment avoidance-constructive conflict resolution and attachment avoidance-social self-efficacy links. Implications of the findings are discussed from the attachment perspective and Chinese cultural contexts.
