Adolescence internalizing problems as a mediator between autism diagnosis in childhood and quality of life in emerging adults with and without autism: a 10-year longitudinal study.

The team tracked the same kids for ten years. They started when the children were about twelve. Some had autism, some did not.

At age twenty-two everyone answered questions about life satisfaction. The study asked whether teen anxiety and depression explained why autistic young adults felt lower quality of life.

Teen anxiety and depression fully explained the link. Autism itself did not directly lower adult life satisfaction. Acting-out behaviors had no mediating role.

In plain words: treat the worry and sadness in high school and you may protect adult well-being.

Gillberg et al. (2016) watched fifty males with Asperger syndrome for twenty years. Almost every man later had extra disorders, especially depression. Andersen’s new data say that those teen mood problems are the very bridge to poor adult life quality.

Golubović et al. (2013) showed that teens with intellectual disability and their parents often disagree on quality-of-life ratings. Andersen used only self-reports at twenty-two, following that caution to let the young adult speak for themself.

Hume et al. (2018) found that parents, teachers, and autistic teens rate transition skills differently. Andersen’s study moves past ratings to show why those skills matter: less teen anxiety means better adult outcomes.

You can’t change an autism diagnosis, but you can treat anxiety and depression. Screen every autistic teen for internalizing problems and run evidence-based CBT or ACT groups. Targeting worry and low mood now may pay off in life satisfaction a decade later.
