Abstract: BACKGROUND: Previous work on the reliability of mental capacity assessments in patients with psychiatric illness has been limited. AIMS: To describe the interrater reliability of two independent assessments of capacity to consent to treatment, as well as assessments made by a panel of clinicians based on the same interview. METHOD: Fifty-five patients were interviewed by two interviewers 1-7 days apart and a binary (yes/no) capacity judgement was made, guided by the MacArthur Competence Assessment Tool for Treatment (MacCAT-T). Four senior clinicians used transcripts of the interviews to judge capacity. RESULTS: There was excellent agreement between the two interviewers for capacity judgements made at separate interviews (kappa=0.82). A high level of agreement was seen between senior clinicians for capacity judgements of the same interview (mean kappa=0.84). CONCLUSIONS: In combination with a clinical interview, the MacCAT-T can be used to produce highly reliable judgements of capacity.
