Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Insufficient information to make a judgement
Allocation concealment (selection bias) Unclear risk Insufficient information to make a judgement
Incomplete outcome data (attrition bias) 
 All outcomes Low risk Low attrition (16%). Full‐information maximum likelihood estimation with robust standard error estimation, which assumes data are missing at random, was used in both Parts 1 and 2
Selective reporting (reporting bias) Low risk All prespecified outcomes were reported
Blinding of participants and personnel (performance bias) 
 All outcomes High risk Not possible to blind participants to intervention. Insufficient information to make a judgement about blinding of therapists
Blinding of outcome assessment (detection bias) 
 All outcomes Low risk Interviewers were not members of the research team, were blind to experimental condition
Unit of Analysis issues Low risk Not applicable
