Greater app engagement was weakly linked to improved depression and anxiety symptoms
A review found a small association between engagement and symptom improvement in app trials. Engagement was measured in many ways, complicating comparisons.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
People who engaged more with depression and anxiety apps tended to show greater symptom improvement, but the pooled association was small. Although the source studies were randomized trials, the analysis examined engagement–outcome relationships. It does not establish that increasing app use causes better outcomes or identify how much engagement is needed.
Studies used varied engagement measures and reporting methods. Some nonsignificant associations lacked numerical data, and only a few studies informed analyses of specific app features or outcomes.
What researchers found
Correlation of engagement with symptom improvement
Greater versus lower app engagement across trials; assessment timeframe not reported. Correlation coefficient averaged across engagement and symptom variables.
Engagement had several definitions
Researchers found many different ways of defining engagement, and some studies tested several measures. This makes it difficult to translate the pooled finding into a simple rule about sessions, time spent, or app activity.
How robust was the link?
The association remained statistically significant after checks addressing publication bias and missing numerical results from studies reporting nonsignificant associations. Those checks support the presence of a small link, while leaving its causal meaning unresolved.
