Overview

AI-generated summary, not a substitute for reading the source.

This secondary analysis of the RESiLIENT trial examines how smartphone-based behavioral activation engagement relates to depressive symptom changes in 298 adults. It categorizes lesson and worksheet completion into four patterns to assess their impact on PHQ-9 scores at weeks 6 and 26. The study finds that early lesson engagement is associated with sustained symptom reduction, while higher worksheet engagement provides benefits primarily in the short term.
