Methods	Trial design: 3‐arm RCT Follow‐up: baseline, post, 4, 8, 12 months Loss to follow‐up: minimal loss to follow‐up, ITT analysis done
Participants	Population: 247 HIV‐positive men (N = 117) and women (N = 130), intervention = 124, control = 123 Inclusion: sexual abuse as a child (age 12 and under) and/or adolescent (age 13 to 17 years); current age of 18 or older; HIV serostatus Exclusion: acute distress due to sexual revictimization experienced within past month; presence of impaired mental status; extreme distress or depressive symptomatology

Random sequence generation (selection bias)	Unclear risk	The trial authors described the trial as 'randomized' but did not provide any further details.
Allocation concealment (selection bias)	Unclear risk	The trial authors did not describe the method of allocation concealment, if any.
Blinding of participants and personnel (performance bias) Anxiety	Unclear risk	The trial authors did not describe the method of blinding, if any.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	The trial authors did not describe the method of blinding, if any.
Incomplete outcome data (attrition bias) All outcomes	High risk	Losses to follow‐up: 16.5% Intervention group versus 33.3% control. The trial authors conducted an intention‐to‐treat analysis.
Selective reporting (reporting bias)	Low risk	We did not detect any other sources of selective reporting bias.
