Coaching vs recommendations in IntelliCare
In a factorial RCT, coaching lowered anxiety more than self-guided use, while weekly app recommendations boosted depression improvement and app sessions.

Comparison of the Effects of Coaching and Receipt of App Recommendations on Depression, Anxiety, and Engagement in the IntelliCare Platform: Factorial Randomized Controlled Trial
Study at a glance
- Design
- RCT — 2×2 factorial: coaching vs self-guided × weekly app recommendations vs none
- N
- N=301 · Adults with elevated PHQ-9 or GAD-7 using IntelliCare suite
- Population
- Adults with elevated depression or anxiety symptoms using IntelliCare Android apps
- Outcome
- PHQ-9/GAD-7 change and app engagement over ~8 weeks

What they did
Adults with elevated PHQ-9 or GAD-7 scores used the IntelliCare Android app suite in a 2×2 factorial randomized trial crossing human coaching versus self-guided use with weekly app recommendations versus none. Engagement and symptom outcomes were tracked over about 8 weeks.
What they found
PHQ-9 and GAD-7 fell significantly over time across arms. Coaching produced larger GAD-7 reductions than self-guided care; recommendations interacted with time to strengthen PHQ-9 gains and raised median app sessions. Engagement was high (median 216 sessions; median last use day 56).
The limits
What it doesn't show
Effects are platform-specific to IntelliCare Android users meeting symptom thresholds. Follow-up loss differed by cell, and coaching did not clearly beat self-guidance on depression. Results do not identify which individual mini-apps drive benefit.
