Risks Associated with Recent Self-Harm in Preadolescent and Adolescent Youth: Parent-Report

Abstract

Objective: Self-harm among children and adolescents is a global public health issue, with concerning trends of increased rates of hospital presenting self-harm in younger age groups (5–12 years). Few studies have investigated risk factors of emerging self-harm in preadolescent populations (<12 years). This study aimed to identify key factors associated with recent (past 12-months) self-harm in preadolescents (5–12 years) compared to adolescents (13–18 years). Method: This cross-sectional case-control study recruited 305 parents/guardians who had a child (aged 5–18 years) that had (i) recently engaged in self-harm (case group) or (ii) never engaged in self-harm (control group). Participants completed an online parent-report questionnaire that assessed demographic characteristics and self-harm, childhood adversity, child-parent relationships, peer relationships, and problematic digital media use. Data were analyzed using univariate and multivariate logistic regression analyses. Results: Poorer emotion regulation (OR = 1/0.76 = 1.32), lower parental age (OR = 1/0.83 = 1.20), lower household income (OR = 4.38), problematic peer relationships (OR = 1.38), and lifetime suicidal ideation (OR = 20.34) were associated with increased odds of self-harm among all youth ages. Higher parent education was associated with greater odds of self-harm among preadolescents (OR = 0.02). Lifetime mental health diagnosis (OR = 7.84) and lower levels of childhood adversity (OR = 0.60) were associated with greater odds of recent self-harm among adolescents. Conclusions: Coordinated multi-agency efforts are essential for holistically addressing common, modifiable individual, social, and socioeconomic risk factors of youth self-harm that may help to prevent onset in young people.
