Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Quote: "After these assessments, the women were randomly assigned to either an Immediate or a Delayed CTT‐BW condition." Comment: The method of random sequence generation was not reported,
Allocation concealment (selection bias)	Unclear risk	Comment: There is no mention of any measures taken to conceal allocation.
Incomplete outcome data (attrition bias) All outcomes	Low risk	Comment: ITT analyses. 1 participant dropped out from the treatment group and 4 from the waitlist.
Selective reporting (reporting bias)	Unclear risk	Comment: All specified outcomes were reported.
Other bias	High risk	Comment: The issue of researcher allegiance cannot be ruled out. Lead author originated CTT‐BW and conducted all therapy.
Blinding of participants and personnel (performance bias) All outcomes	High risk	Comment: Participants were aware of their allocation.
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Quote: "The assessors were blind to participants’ condition assignments."
