Mobile technology boosts the effectiveness of psychotherapy and behavioral interventions: a meta-analysis.

Oliver and colleagues looked at 25 therapy trials that added mobile tech. The tech was apps, texting, or old-school PDAs.

All studies mixed different diagnoses. The team asked one question: does adding a phone boost the main treatment?

Yes. The phone add-ons gave a small but steady lift in client outcomes across every trial.

The boost showed up no matter what the main therapy was. Mobile tech is a reliable side-kick, not a star.

EGranieri et al. (2020) later checked 18 social-skills trials for autism. They saw no difference between app-based and face-to-face SST. That seems to clash with Oliver’s small boost, but the two meta-analyses asked different things. Oliver looked at any therapy plus tech; EE compared tech-only against live coaching. The small boost may come from the extra reminders, not from replacing the coach.

Single studies keep extending the idea. Zohrabi et al. (2025) used a BCBA-managed video app to teach self-care to kids with autism. The app worked as well as live modeling, matching EE’s finding. Zhou et al. (2018) added live coaching inside the same app and parents hit over 85 % fidelity. The pattern: apps alone equal live, apps plus coach beat live.

Dallery et al. (2021) pushed the ceiling even higher. Their smoking-cessation app paired large cash rewards with photo-verified CO samples. Abstinence jumped from 4 % to 89 %—a huge leap, not a small one. The takeaway: mobile tech can give either a small nudge or a giant shove; size depends on what you bolt onto the phone.

You don’t need to rebuild your whole program. Slip a phone piece into what you already do and you should see a small, reliable gain. Try daily text reminders, five-minute video models, or quick pulse surveys. If you want more than a nudge, pair the app with high-value rewards or live BCBA check-ins. Rural families, busy parents, and older kids with phones are perfect first targets.
