Methods	Design: single‐blind (participants) randomizedd clinical trial. Randomization: 2‐arm parallel group. Duration of study: not reported.
Participants	Number randomized: 20 participants living in community with moderate‐to‐severe acquired brain injury, aged 18‐55 years. Inclusion criteria: medically stable; oriented to person, time and community; independent in basic self‐care tasks as determined by FIM; problems with self‐awareness identified by treating therapist. Exclusion criteria: participants with aphasia, severe visual problems, primary psychiatric problems/substance abuse diagnosis based on reports by treating physicians and therapists.
Interventions	Intervention: self‐awareness training. Performance of instrumented activities of daily living: prepare a birthday gift; prepare a lunch box; pay a telephone bill; make a doctor appointment; arrange tablets in a tablet organizer; prepare a birthday cake. Participants were asked to predict the performance before completing each task and then asked to assess their performance immediately following the completion of each task. If a participant identified a specific problem, he/she was asked to think of a strategy for better and easier task performance. Duration: 6 individualized treatment sessions over 3 weeks, 1 session per day on 2 or 3 days every week. Each session consisted of a maximum of 45 minutes. Control: same ADL task as the treatment group, but participants were not given specific self‐awareness intervention by the therapist. They were given conventional practice of corrective feedback from the therapist. Duration: same as intervention group.
Outcomes	Community Integration Questionnaire (CIQ); Assessment of Motor and Process Skills (AMPS) to assess ADL and IADL. Awareness Questionnaire, Assessment of Awareness of Disability, Self‐Regulation Skills Inventory, Satisfaction with quality of care.
Notes	Setting: Cognitive Remediation Program at Kessler Institute for Rehabilitation, New Jersey. Country: US. Duration of follow‐up: none. Dropouts: none. Funding: National Institute on Disability and Rehabilitation Research; Mary E. Switzer Research Fellowship Program (Grant Award Number: H133F0400180).
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Quote: "Participants were then randomly assigned to either the control or experimental group by the second author of this paper." Comment: insufficient information about the method of randomization. The author could not provide further details.
Allocation concealment (selection bias)	High risk	Quote: "Participants were then randomly assigned to either the control or experimental group by the second author of this paper." Comment: insufficient allocation concealment since 1 of the authors was involved in the allocation process, and method of allocation concealment could not be verified.
Blinding of participants and personnel (performance bias) All outcomes	Low risk	Quote: "Participants remained blind to the group membership." Comment: blinding of participants was adequate. Blinding of personnel not reported.
Blinding of outcome assessment (detection bias) Objective outcomes	High risk	Comment: blinding of outcome assessment not reported.
Incomplete outcome data (attrition bias) All outcomes	Low risk	Comment: no dropouts.
Selective reporting (reporting bias)	Low risk	Comment: none identified.
Other bias	Low risk	Comment: no additional biases were detected.
