Healthy Minds: Group Cognitive-Behavioral Intervention for Sustainable Return to Work After a Sick Leave Due to Depression.
Marc Corbière, Jean-Philippe Lachance, Francelyne Jean-Baptiste and 3 others
PMID 34279759WHAT IT FOUND
In a small pilot, the work-focused group CBT did not clearly reduce depressive or anxiety symptoms more than control.
Work productivity scores improved in the intervention group from baseline to post-intervention and six-month follow-up, but this was a pilot with 30 participants.
Key findings
01The between-group comparison for depressive and anxiety symptoms was inconclusive.
02Work productivity had a significant time-by-group interaction, with post-hoc differences in the intervention group from baseline to post-intervention and six-month follow-up.
03Participants attended most sessions, averaging 6.5 of 8 sessions.

What it does not show
The study had 30 participants, and the paper says a post-hoc power analysis suggested 66 participants would be needed. The design was quasi-experimental, with participants approached by week rather than through a conventional random allocation process. Control participants were not told they were in a control condition. The intervention group started with more severe symptoms and lower work productivity than the control group, so room for improvement may affect the results. Other services received by participants were not documented. Work accommodations were discussed in the intervention but were not measured, so their role in outcomes cannot be determined. Groups were offered in the evening, which may have deterred participants with lower energy. The authors reported difficulty recruiting and keeping people in the control condition.
Declared interests
The paper names Healthy Minds Canada as funder.
The easy way to misread this
Do not conclude that Healthy Minds reduces depression or anxiety more than the control condition. The between-group symptom comparisons were inconclusive, and the study was a small pilot with baseline differences between groups.
