Bolton 2007.

Methods	RCT
Participants	Acholi adolescents 14 to 17 years of age, living in 2 camps for internally displaced persons near Gulu, Uganda. The war in Northern Uganda represents one of the most violent and persistent complex humanitarian emergencies in the world. Over 1.8 million individuals, mainly ethnic Acholi, have been internally displaced during 20 years of conflict between the government of Uganda and the Lord's Resistance Army. Eligible participants scored greater than 32 on the depression symptom scale and greater than 0 on the function scale; had symptoms for at least 1 month; and resided in the camps during the preceding month. Exclusion criteria were inability to be interviewed due to a cognitive or physical disability and severe suicidal ideation or behaviour
Interventions	Group interpersonal psychotherapy (IPT‐G): 105 participants Wait list: 104 participants Creative play (CP): 105 participants
Outcomes	Depressive symptoms; anxiety symptoms; conduct problems; functioning. Recovery, defined as a reduction of 50% or more of an individual's baseline symptom severity score; remission, defined as at or less than a predefined cutoff score of 15.6 points (mean score of non‐cases in the validation study)
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "Random allocation was done by computerized generation of a random number between 1 and 400 for each eligible participant, ordering them by number and assigning the first third to IPT‐G, the second third to CP and the final third to the wait‐control group"
Allocation concealment (selection bias)	Unclear risk	No information provided
Blinding of participants and personnel (performance bias) All outcomes	High risk	Quote: "Informed consent included advising each youth of the study group to which he or she had been allocated"
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Quote: "Interviewers were blinded to interviewees’ intervention status"
Incomplete outcome data (attrition bias) All outcomes	Low risk	Dropouts reported at study endpoint (17/105 missing from creative play group; 9/105 missing from interpersonal psychotherapy group; 16/104 missing from control group)
Selective reporting (reporting bias)	Low risk	All outcomes are correctly reported
Therapist qualification	Unclear risk	Interventions were delivered by trained facilitators
Treatment fidelity	Unclear risk	Quote: "IPT supervisors also provided weekly written reports that were reviewed and discussed with study staff during the phone meetings for adherence to the treatment model and to monitor human subject protection"
Therapist/investigator allegiance	High risk	Manualised IPT was developed in the United States, and study authors were involved in training facilitators
Other bias	Unclear risk	No information provided
