Risk of bias
Bias	Authors' judgement	Support for judgement
Allocation concealment (selection bias)	Unclear risk	It is unclear from the study text whether allocation was concealed
Blinding (performance bias and detection bias) All outcomes	Low risk	"Scoring was primarily conducted by a therapist who was not involved in the programme implementation and blinded to the grouping of participants," which indicates low risk but "primarily conducted" may imply that not all assessments were conducted by this therapist. The study was single‐blind as the participants were not blinded to their allocation
Incomplete outcome data (attrition bias) All outcomes	Low risk	Complete data on 21 participants were presented
Other bias	Low risk	No other sources of bias identified
