Quality of Life in Heterogeneous Anxiety Disorders: Changes Across Cognitive-Behavioral Treatments.
CBT boosts quality of life for adults with mixed anxiety disorders, regardless of specific protocol.
01Research in Context
What this study did
Arwert et al. (2020) split anxious adults into three groups. One group got the unified transdiagnostic CBT. One got single-disorder CBT. One waited with no treatment. The team tracked quality of life before, after, and six months later.
What they found
Both CBT groups felt better than the wait-list. Their gains in quality of life stayed strong six months later. The exact CBT flavor—unified or single-disorder—did not matter.
How this fits with other research
Dudley et al. (2019) ran the child version of the same unified protocol. Kids aged 7-13 also beat the control on anxiety and mood, showing the idea works across ages.
Perihan et al. (2020) pooled 23 studies of CBT for anxious children with ASD. They saw moderate anxiety drops, especially when parents joined. Arwert et al. (2020) now shows similar benefit in neurotypical adults, widening the evidence base.
Byiers et al. (2025) went further by letting caregivers pick the top three problems for autistic 5- to 11-year-olds. That tweak sped improvement. Together the papers say: CBT works for anxiety, and small customizations can make it work faster.
Why it matters
You can use either unified or single-disorder CBT with anxious adults and still expect better life quality that lasts. If you work with kids or autism, borrow the caregiver-goal trick from Byiers et al. (2025) to speed gains. One size fits most, but a quick tailor job fits better.

03Original abstract
Quality of life is lower among individuals with anxiety disorders; however, this construct is rarely a focus in treatment research. This study explores changes in quality of life in a randomized, controlled trial of several cognitive-behavioral treatments (CBTs) for anxiety disorders. Adults with heterogeneous anxiety disorders (N = 223) were randomly assigned to (a) unified protocol for transdiagnostic treatment of emotional disorders, (c) a single-disorder protocol targeting their principal diagnosis, or (c) a waitlist control condition, and assessed at baseline, posttreatment, and 6-month follow-up. At baseline, the sample evidenced deficits in quality of life, with no significant differences in quality of life across diagnoses or condition. Results suggest improved quality of life among participants in treatment, at similar rates across treatment condition and diagnostic category, and at levels significantly higher than the waitlist. Improvements were maintained through 6-month follow-up. This study supports CBT as effective in promoting quality of life.
