Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	High risk	Quote: "Participants were assigned through a random selection procedure of participants name‐cards to one of two treatment groups: NET and PED." Comment: It is unclear how exactly this was performed.
Allocation concealment (selection bias)	Unclear risk	Comment: The authors do not report any methods of allocation concealment.
Incomplete outcome data (attrition bias) All outcomes	Low risk	Comment: No drop‐outs.
Selective reporting (reporting bias)	Low risk	Comment: All specified and expected outcomes appear to have been reported.
Other bias	High risk	Comment: Very small sample size
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: "Our intent was to perform a blinded assessment by keeping the interviewers unaware of the treatment condition and pre‐test scores of the individual patients and by instructing the patients not to inform the interviewers about their treatment. However, due to the large differences in procedures and number of sessions between the two treatment conditions, it was not possible for us to achieve complete blindness in all cases. Occasionally, a patient revealed details about his treatment that might have affected the blindness of the interviewer."
