Hopelessness as a Mediator of the Association Between Parenting Factors and Adolescent Suicidality and Substance Use Among Juvenile Justice‐Referred Youth

Youth involved in the juvenile justice system are more likely to have a substance use disorder and/or suicidality (e.g., suicidal thoughts and behavior) compared to other youth. Although parental support and monitoring may play an important role in youth substance use and suicidality outcomes, the potential mechanisms have not been elucidated. Our purpose was to evaluate the extent to which parental support and monitoring were associated with latent, continuous construct scores of suicidality and substance use and to determine whether youths' hopelessness may indirectly affect these relationships among a sample of youth referred to the juvenile justice system. The sample included juvenile justice-referred youth aged 14-17 (<i>N</i> = 77; 69% White, 58% male, 74% non-Hispanic). The primary predictors of interest were parental support and monitoring, measured by the Parent Support Scale and Parental Monitoring Scale. The primary potential mediator of interest was hopelessness. Linear regression was used to model continuous suicidality and substance use severity scores, measured via a computer adaptive test, on parental support and monitoring. We tested hopelessness as a potential mediator. All analyses controlled for age, sex assigned at birth, race, ethnicity, and family income. After adjustment, parental support was associated with decreased suicidality severity (<i>β</i> = -0.30, <i>p</i> = 0.002). Parent support and monitoring were associated with youth-reported hopelessness. The indirect mediation effects of hopelessness in the relationship between parental support (<i>β</i> = -0.18 [SE, 1.73]), as well as parental monitoring (<i>β</i> = -0.17 [SE, 0.20]), and suicidality severity were statistically significant. Parental support and youth hopelessness may be important intervention targets for improving and addressing disparities in substance use and suicidality among juvenile justice-referred youth. Hope-based interventions may be effectively integrated into existing juvenile justice programs, and their potential to improve both mental health and behavioral outcomes among justice-involved youth should be examined.
