High-risk substance use and psychosocial functioning in young adult care leavers: Findings from a 10-year follow-up study

Abstract

BackgroundCare leavers transitioning into adulthood represent a highly vulnerable population, confronted with usual developmental tasks under difficult predisposing conditions. Early-risk and persistent substance use may be an obstacle for care leavers transitioning from youth residential care settings into an independent adult life. ObjectivesThis study aims to address the following questions: (1) How stable is high-risk substance use from within care to after youth residential care? (2) Are there differences between longitudinal substance use risk pathways and sociodemographic characteristics, placement history, and adverse exposures? (3) Is the persistency of high-risk substance use associated with impaired young adult psychosocial functioning?Method:In a prospective longitudinal design, with a baseline in youth residential care (t1) and a follow-up ten years later (t2), we investigated the courses of substance use in 182 young adult care leavers in Switzerland (32.4 % women; Meanage = 26.7 years). Psychosocial functioning was assessed across health, legal, educational, and financial domains. ResultsWe found large prevalence rates of high-risk substance use in and after residential youth care (41.2 % in residential care; 46.2 % after leaving care). Of those care leavers who reported earlier high-risk substance use, 61.3 % persisted, while 38.7 % remitted. Four substance risk pathways were identified longitudinally: low (N = 69, 37.9 %), remitted (N = 29, 15.9 %), newly-developed (N = 38, 20.9 %), and persistent risk (N = 46, 25.3 %). Persistent high-risk substance use was associated with higher rates of adverse functional outcomes in young adulthood. ConclusionsFindings of this study shed light on the high prevalence of earlier and persistent high-risk substance use in youth residential care leavers. High-risk substance use appears to have the potential to coincide with impaired psychosocial functioning during and after the transition to young adulthood. Implications for educational and vocational paths as well as harm-reducing interventions are discussed. More research disentangling risk pathways and intervention research in at-risk populations is warranted.
