Homework assignments extend therapy impact. This study investigated the role of reviewing action recommendations from therapy sessions in subsequent sessions and its impact on patient outcomes. Real-world data from 2,444 therapy sessions were analyzed. Machine learning and natural language processing techniques were used to detect action recommendations and their review. The proportion of session dialogues that included a review of action recommendations served as an indicator of review intensity. Using Generalized Estimating Equations modeling, we examined the association between this review metric and changes in clients' depression and anxiety scores. Therapists in community-based programs typically provided clients with one to eight activity recommendations per session to engage in outside of therapy; however, about half of the sessions included a review of previously assigned action recommendations. A significant interaction between the initial depression score and the percentage of activity recommendations reviews emerged (p=. 045). After controlling for this interaction, this review percentage was significantly associated with changes in depressive symptoms (p=. 032). Post-hoc analyses revealed a significant positive association between the review percentage and changes in score within the mild depression category (p=. 024). We found no such associations for anxiety or moderate to severe depressive symptoms. Therapists' review of action recommendations from previous sessions may positively impact depression outcomes, particularly for clients with mild depression …
