Conclusions/limitations
- CBT delivered via the Perspectives app and a coach proved to be effective treatment for adults with BDD.
- Adoption of the application was relatively high; 86% of Perspectives users were very or mostly satisfied.
- Limitations: Because the participants in this study were predominantly female and White, the findings might not be generalizable to other populations.

Insomnia remains a substantial problem among military veterans. First-line treatments for the disorder are sleep hygiene modification and CBT. Access to CBT is limited, especially for veterans. Kuhn et al11 studied the effectiveness of using Insomnia Coach, a CBT for insomnia–based app, to improve insomnia symptoms.
Study design
- Fifty US veterans who were mostly male (58%) with a mean age of 44.5 and moderate insomnia symptoms were randomized to use Insomnia Coach (n = 25) or to a waitlist control group (n = 25) for 6 weeks.
- All participants completed self-report measures and sleep diaries at baseline, posttreatment, and follow-up (12 weeks). Those who used the app (n = 15) completed a qualitative interview at posttreatment.
Outcomes
- At posttreatment, 28% of participants who used Insomnia Coach achieved clinically significant improvement, vs 4% of waitlist control participants. There was also a significant treatment effect on daytime sleep-related impairment (P = .044, d = -0.6).
- Additional treatment effects emerged at follow-up for insomnia severity, sleep onset latency, global sleep quality, and depression symptoms.
- Based on self-reports and qualitative interview responses, participants’ perceptions of Insomnia Coach were favorable. Three-fourths of participants used the app through 6 weeks and engaged with active elements.
