Parents and friendships: a longitudinal examination of interpersonal mediators of the relationship between child maltreatment and suicidal ideation.

This study examined parental relationship quality, friendship quality, and depression as mediators of the association between child maltreatment (CM) and adolescent suicidal ideation (SI). Participants were 674 adolescents (46% female; 55% African American) involved in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Data were collected via youth self-report at ages 12, 16, and 18. CM before age 12 predicted poor parental relationships and depression, but not poor friendships, at age 16. Age 16 depression was negatively associated with parental relationship quality and positively associated with SI at age 18. An indirect path from CM to SI via depression was significant, suggesting that the early CM affects depression severity, which in turn is associated with SI. Strong friendship quality (age 16) was associated with SI at age 18; however, there was no significant indirect path from CM to SI via friendships. Results suggest that: 1) CM before age 12 affects parental relationships in adolescence; 2) depression and friendships are related to suicide ideation in later adolescence; and 3) depression partially mediates the association between CM and SI. Results highlight the importance of assessing for a history of CM, quality of interpersonal relationships, and depression severity among youth reporting SI.
