Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Probability of assignment to the nonresidential group was set at twice that of the other groups. Random assignment was made within two blocking variables, gender and primary type of mental disorder.
Allocation concealment (selection bias)	Unclear risk	Allocation concealment not reported
Blinding of participants and personnel (performance bias)	High risk	Participants and personnel could not be blinded to the intervention.
Blinding of outcome assessment (detection bias)	Unclear risk	Blinding of outcome assessment not reported.
Incomplete outcome data (attrition bias)	High risk	Rates of completed follow‐up were 79% for the 3‐month follow‐up, 76% for the 6‐month follow up, 70% for the 9‐month follow‐up, and 58% completed all three follow ups. At the 9‐month follow‐up the completion rate among those assigned to the control group (57%) was significantly lower than among those assigned to nonresidential treatment (76%).
Selective reporting (reporting bias)	Low risk	No evidence of selective outcome reporting.
