Predicting Post-School Outcomes in Autistic Young Adults One Year after High School Graduation.
Treating depression in autistic high-school seniors may be the fastest way to boost their jobs, friendships, and independent living one year later.
01Research in Context
What this study did
The team followed autistic high-school seniors for one year after graduation. They asked how senior-year depression and executive-function skills shape adult life.
No new treatment was tested. The study simply tracked mood, thinking skills, and later outcomes like jobs, friendships, and living on their own.
What they found
Students who felt more depressed in senior year had poorer adult outcomes twelve months later. Depression carried the full weight of the link between weak executive function and later struggles.
In plain words: poor planning or memory alone did not predict failure—depression did.
How this fits with other research
Chien et al. (2024) showed childhood inattention and social problems forecast later executive-function trouble. The new study flips the lens: it shows how senior-year mood turns those thinking problems into real-life setbacks.
Howard et al. (2023) and Ferraiolo et al. (2026) both found poor sleep raises depression in the same age group. Together the papers form a chain—sleep loss can deepen mood issues, and mood issues then block adult success.
Gilmore et al. (2022) add a warning: Black autistic youth already carry higher depression loads. The mediation effect seen here may hit them hardest, so culturally tailored mood screening is urgent.
Why it matters
You already check IEP goals and daily living skills. Add a quick depression screen each quarter of senior year. Treat mood first—through CBT, better sleep habits, or peer groups—before pouring hours into extra executive-function drills. A happier senior year may unlock the independence you and the family want after graduation.

03Original abstract
The aim of the present longitudinal study was to identify malleable factors during the last year of high school that predicted post-school outcomes in autistic youth one year after high school graduation. We then explored whether depressive symptoms in high school mediated the associations between other malleable factors and post-school outcomes. Thirty-two autistic youth and a parent completed surveys during the youth's final year of high school (T1) and one-year post-high school graduation (T2). Malleable factors measured at T1 included social communication skills, executive functions, responsibility for daily tasks, and depressive symptoms. The T2 young adult outcome measure included both objective and subjective indicators of productivity, social well-being, and autonomy in living situation. All malleable factors except social communication skills were significantly correlated with young adult outcomes. T1 executive functions, responsibility for daily tasks, and depressive symptoms jointly predicted 40.2% of the variance in young adult outcomes. Only depressive symptoms explained a significant amount of unique variance in young adult outcomes. In addition, depressive symptoms mediated the predictive association between executive functioning and young adult outcomes. The findings suggest that depressive symptoms may be a key intervention target for autistic high school students. Adapting cognitive behavioral approaches to comprehensively address multiple transdiagnostic factors such as executive functions, responsibility for daily tasks, and mental health may be a promising avenue to promote positive post-school outcomes in this population.
