The impact of depressive and anxious symptoms on quality of life in adults on the autism spectrum.
Depression—not autism—drives most of the quality-of-life deficit in autistic adults, so screen and treat depression first.
01Research in Context
What this study did
Thiel et al. (2024) compared quality of life in autistic adults and neurotypical adults. They used surveys to measure mood and daily satisfaction.
What they found
Autistic adults rated their lives lower than neurotypical adults. Depressive feelings, not autism traits, explained most of the drop.
How this fits with other research
Burrows et al. (2018) saw the same pattern in kids: sleep, gut, and mood issues dragged quality of life down more than autism itself.
Yamashiro et al. (2019) showed that brooding rumination fuels depression in autistic adults. The new study adds that this depression then erodes life satisfaction.
Totsika et al. (2010) looked at adults 50-plus with autism plus intellectual disability. After accounting for daily-living skills, autism added no extra quality-of-life hit. The 2024 study focused on adults without ID and still found a hit—because depression was present. The two papers agree: skills and mood matter more than the label.
Why it matters
Screen every autistic adult for depression first. Treating sad mood, sleep, or brooding thoughts can lift life satisfaction faster than autism-specific coaching. Add a short mood checklist to your intake packet and link clients to CBT or medical care when scores are high.

03Original abstract
Quality of life (QoL) is lower in adults on the autism spectrum (AS) compared with typically developing (TD) adults. In this context, recent studies have examined the role of depression and anxiety in reducing QoL in AS adults. The aim of this study was to (1) replicate these findings of lower QoL and (2) assess the negative influence of depressive and anxious symptoms on QoL in an adult AS (N = 86) and TD (N = 87) German sample with a broad age range (18-70 years). For this, we used questionnaires that have been validated for the AS and TD population: the World Health Organization Quality of Life Brief Version, the Autism-Specific QoL items, and the Hospital Anxiety and Depression Scale. We replicated previous findings and extended them to autism-specific QoL. Our AS sample had lower QoL compared with the TD adults. However, depressive symptoms were the largest contributor to lower QoL in both samples, more so than group membership and anxious symptoms. We conclude that interventions to improve QoL in AS adults should specifically target depressive symptoms and for this, improvements to the diagnostic process and treatment of depression in AS are necessary.
