An evaluation of intervention research for transition-age autistic youth.
Most studies targeting autistic teens and young adults are too weak to trust—insist on stronger evidence before you act.
01Research in Context
What this study did
Bottema-Beutel et al. (2023) hunted for every published intervention study aimed at autistic youth aged 14-22.
They screened hundreds of papers and kept only the ones that tested a program meant to help these teens and young adults move into adult life.
Then they graded each study for scientific rigor and looked for any mention of side effects or harm.
What they found
Most studies were small, short, and poorly designed. Many lacked control groups or clear outcome measures.
Almost none checked whether the intervention caused stress, anxiety, or other unwanted effects.
The authors conclude the evidence base is too shaky to trust.
How this fits with other research
Broadstock et al. (2007) said the same thing sixteen years earlier about drug studies in the same age group. The problem is old, not new.
Whiting et al. (2015) warned that adult autism research was weak; Kristen shows the teen side is still weak too.
Adams (2026) found almost no data on single-session mental-health programs for autistic people. Kristen’s team found almost no solid data on full transition programs. Both reviews end with the same empty shelf.
Kim et al. (2024) reviewed stigma-reduction trainings and also saw mostly one-shot, low-quality designs. The pattern repeats across topics.
Why it matters
Before you adopt a new transition program, demand proof. Ask for a control group, long-term follow-up, and harm checks. If the study can’t provide them, treat the program as experimental. Your clients deserve no less.

03Original abstract
In this study, we assess the quality of intervention research that focuses on autistic youth who are 14-22 years old. We found 193 different studies on this topic, and carefully reviewed them. Most of these studies tested strategies that were behavioral. This means that they used procedures like prompting and rewards to change participants' behavior. We found that the majority of studies had problems that make it hard to determine whether or not the intervention worked. The problems related to how researchers designed their studies, and how they measured the study outcomes. We also found that researchers rarely tried to find out if the strategies they studied had unintended negative effects for participants. Because of these issues, we make suggestions for how researchers might design better studies that will let people know how well the strategies worked.
