Mental disorder trajectories and quality of life among youth residential care leavers: a longitudinal study.

BACKGROUND

Adults formerly placed out-of-home (care leavers) often accumulate multiple psychosocial adversities that can lead to poor quality of life (QoL) and place them at high risk for developing mental disorders persisting into adulthood. This study examines the development of mental disorders among care leavers and their QoL, differentiating by disorder groups.

METHODS

The sample consisted of 119 young adults formerly placed out-of-home (Mage at baseline = 15.0 years; Mage at follow-up = 25.4 years). Mental disorders were assessed at baseline using the Kiddie Schedule for Affective Disorder and Schizophrenia-Present and Lifetime Version and at a 10-year follow-up with the Structured Clinical Interview for DSM-5 Disorders-Clinician Version. Personality disorders were evaluated at both time points using the Structured Clinical Interview for DSM-IV-TR Axis II. QoL was measured at follow-up using the World Health Organization QoL-BREF questionnaire.

RESULTS

Four groups based on the presence or absence of mental disorders at baseline and follow-up were identified: resilient (n = 24, 20.2%), persistent (n = 56, 47.0%), remitted (n = 25, 21.0%), and newly occurring (n = 14, 11.8%). Regarding the mental disorder groups, internalizing disorders at baseline (β = -0.44, p < .05, 95% CI [-0.85, -0.04]) and internalizing (β = -0.78, p < .001, 95% CI [-1.14, -0.43]) and externalizing disorders (β = -0.50, p < .01, 95% CI [-0.86, -0.13]) at follow-up were negatively associated with QoL in young adulthood.

CONCLUSIONS

Mental disorder trajectories from childhood to young adulthood can negatively impact care leavers' QoL. Prevention and early intervention, as well as addressing mental health during out-of-home placement and transition into young adulthood, are important to reduce the risk of persistent psychopathology and lower QoL.
