The relationship between parenting behavior, suicidal ideation, and suicide attempt across two population-based...

We examined the relationship between parenting, suicidal ideation (SI), and the transition from SI to suicide attempt (SA), and whether parenting behaviors moderate the associations of genetic liability for SA and/or painful and provocative events (PPEs) with SA risk. Participants included 6153 adolescents (48.3 % female, M_age at baseline = 9.47 years, followed over 3 years) from the Adolescent Brain Cognitive Development Study (ABCD) and 5942 adolescents (52.1 % female, M_age at baseline = 15.55 years, followed over 1 year) from the National Longitudinal Study of Adolescent to Adult Health (Add Health). We used logistic regression to test associations between parenting and SI/SA. Genetic liability and PPEs were included as potential predictors of SA. In ABCD, higher parental acceptance and monitoring were associated with lower risk for SI (odds ratios [ORs] = 0.7-0.9, ps < .01) but not SA (ORs = 0.9, ps > .05). Non-suicidal self-injury and parental knowledge of child SI were associated with elevated risk for SA (ORs = 2.6-2.8, ps < .01), but their interaction was non-significant (OR = 0.9, p = .85). In Add Health, maternal support was related to reduced SI risk (OR = 0.8, p < .01), but paternal support, and both parents' involvement and presence at home, were not (ORs = 0.9-1.0, ps > .05). Several PPEs were associated with higher SA risk (ORs = 1.3-2.0, ps < .05). These findings suggest that the parent-adolescent relationship may be more relevant to SI, rather than the transition from SI to SA.
