Psychometric Properties of Measuring Tools for Depression in Autistic Youths: A Systematic Review.
Use the PHQ-9, HADS, or EDA when screening depression in autistic youth — standard scales miss the mark.
01Research in Context
What this study did
Young et al. (2025) hunted for every paper that checked if depression questionnaires work for autistic young people.
They read the fine print on how each tool was built and if it really measures low mood in this group.
Only studies that reported reliability, validity, or sensitivity in autistic youth were kept.
What they found
Most common scales like the CDI and BDI lack autism-focused norms or items.
Tools that center on behavior, sleep, or irritability — or were written with autistic voices — held up better.
The PHQ-9, HADS, and the newer EDA came out on top for balanced accuracy.
How this fits with other research
Gotham et al. (2015) already warned that standard depression questions are only modestly valid in verbally fluent autistic teens and adults. The new review widens the lens and names the same problem, so the two papers agree.
Stanford et al. (2026) show that anxiety scales (GAD-7, DASS-21) are internally solid for autistic adults. Héloïse et al. now show the mirror picture for depression tools in youth: some work, many don’t — a helpful side-by-side reminder to pick the right construct-specific tool.
Garrison et al. (2025) found most autistic adolescents with intellectual disability can still self-report anxiety when given support. This supports Héloïse’s takeaway that youth can complete the PHQ-9 or HADS if you accommodate language level — no need to skip self-report entirely.
Why it matters
Before you treat depression you have to spot it. Swap in the PHQ-9, HADS, or EDA first, then watch scores alongside sleep and behavior data. If a teen has limited verbal skills, shorten items, offer visuals, and keep the parent scale as backup. Good measurement keeps medical providers, families, and insurers on the same page and prevents both missed depression and false positives.

03Original abstract
While autistic individuals are 4 times more likely to have depression compared to non-autistic individuals, depression remained largely undetected in this group resulting in significant unmet needs. A systematic literature review was conducted to determine the psychometric properties of measuring tools for depressive symptoms in autistic children and adolescents. The review followed the PRISMA 2020 guideline (PROSPERO: CRD42023423377) based on the search of several databases from 1980 until November 2024. The COnsensus-based Standards for the Selection of health status Measurement INstruments (COSMIN) checklist was used to assess for each tool: internal consistency, reliability, measurement error, content validity, structural validity, hypothesis testing, criterion validity, responsiveness to change and cross-cultural validity. The review found 15 empirical studies evaluating the properties of twelve measuring tools for depression in autistic youths. The validities of standards screening scales were low, but better for questionnaires with items focusing on behavioral aspects of depression, i.e., the Patient Health Questionnaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS). The evidence supporting the quality of the instrument was much better for those developed for subjects with neurodevelopmental divergences, such as The Evaluation of Depressive symptoms in Autism (EDA), with five domains of psychometric properties rated as strong or moderate. To determine the optimal approach for the use of consensual instruments, further research should include more individuals with co-occurring neurodevelopmental conditions, a risk factor for a more resistant form of depression, and examine the instruments' capacity to detect clinically significant changes during an intervention.
