Longitudinal Effects of Adolescent Abuse on Relationship Quality and Posttraumatic Stress Symptoms in Mother-Adolescent Dyads.

The current study examined dyadic reports of mother-adolescent relationship quality (RQ) as a mechanism by which emotional, physical, and sexual abuse affect posttraumatic stress symptoms (PTSS) over time from a family systems perspective. We used three waves of data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN), including 321 mother-adolescent dyads observed when adolescents were approximately 12, 14, and 16 years old. We used an extended version of the actor-partner interdependence mediation model to analyze the effect of emotional, physical, and sexual abuse on adolescents' PTSS through dyadic reports of mother-adolescent RQ. Results yielded significant indirect effects between sexual and emotional abuse, but not physical abuse, and PTSS 4 years later through adolescent perceptions of RQ. Maternal perceptions of RQ were not directly associated with adolescents' PTSS; however, maternal perceptions of RQ positively contributed to future adolescent perceptions of RQ. Clinical implications are discussed.
