Adolescent-Mother Attachment and Dyadic Affective Processes: Predictors of Internalizing and Externalizing Symptoms

Given that adolescence is a critical period for socioemotional development, marked by shifting dynamics in the parent-child relationship, parent-adolescent dyadic regulation may serve as a key mechanism linking the quality of the parent-adolescent relationship to adolescent mental health. The current study investigated two dyadic regulatory processes during mother-adolescent conflictual interactions as interpersonal mechanisms underlying the link between adolescent-mother attachment security and adolescents' internalizing and externalizing symptoms: (a) mutual engagement in positive affect (i.e., dyadic positivity) and (b) mutual engagement in re-coordination following relational mismatches (i.e., dyadic repair). Eighty-six adolescents (M_age = 13.3 years, SD = 0.6, 37% girls) and their mothers participated. Path models revealed that attachment security was associated with greater engagement in dyadic positivity and repair. Moreover, the indirect effect of attachment security on adolescents' symptoms (i.e., internalizing symptoms at age 13 and externalizing symptoms at age 14) was significant via dyadic positivity, but not dyadic repair. Dyadic positivity during mother-adolescent conflictual interactions may be one interpersonal process that underlies the link between a secure child-mother attachment and mental health during adolescence.
