Depression and its measurement in verbal adolescents and adults with autism spectrum disorder.
Standard depression questionnaires give fuzzy results for verbally fluent clients with ASD—verify with an interview before labeling.
01Research in Context
What this study did
Gotham et al. (2015) tested how well common depression questionnaires work for verbally fluent teens and adults with autism.
They gave several standard scales to a small group and checked if scores matched clinical interviews.
What they found
The tools caught some depression signs, but none gave a clear yes-or-no answer.
Cognitive items like "I blame myself" were often high even when full depression was absent.
How this fits with other research
Young et al. (2025) later pooled many studies and reached the same warning: usual depression scales lack validity for autistic youth.
Gotham et al. (2014) had already shown that rumination and feeling different track with these shaky scores, so the weak tools may still point to real distress.
Stanford et al. (2026) give a bright spot: anxiety scales like GAD-7 hold up well in the same population, showing the problem is specific to depression measures, not self-report in general.
Why it matters
If a teen with ASD scores high on the PHQ-9, treat it as a yellow flag, not a diagnosis. Follow up with an interview, ask about sleep and bullying, and consider autism-friendly tools like the EDA. Your caution prevents both missed depression and overtreatment.

03Original abstract
In a sample of 50 verbally fluent adolescents and adults with autism spectrum disorders (age: 16-31 years; verbal IQ: 72-140), we examined the pattern of response and associations between scores on common measures of depressive symptoms, participant characteristics, and clinical diagnosis of depressive disorders. Beck Depression Inventory-Second Edition item descriptives in this autism spectrum disorder sample were compared to previously published data from a large typically developing sample, with results suggesting that cognitive-attributional symptoms of depression may be particularly prevalent in autism spectrum disorder. Scores on a variety of self- and parent-report depression measures were not associated with chronological age or verbal IQ, and were relatively highly correlated with each other and with clinical diagnosis of a mood disorder. The Beck Depression Inventory-Second Edition and the Adult Self-Report "Depressive" scale best identified both depressed and non-depressed participants in this sample, though neither was particularly strong. Validation studies of depression measures in the autism spectrum disorder population are necessary to advance research into this prevalent and impairing comorbidity.
