Background and objective: To validate the MacArthur Competence Assessment Tool for Treatment (MacCAT-T) Spanish version, which assesses the mental capacity of patients to consent treatment, by examining 4 areas (Understanding, Appreciation, Reasoning and Expressing a choice). %26lt;br%26gt;Patients and method: Sample: 160 subjects (80 Internal Medicine inpatients, 40 Psychiatric inpatients and 40 healthy controls). Instruments: MacCAT-T, Mini-Mental Status Examination (MMSE). Procedure: Feasibility study, reliability and validity calculations (against to gold standard of clinical expert). %26lt;br%26gt;Results: Mean duration of the MacCAT-T interview was 18 min. Inter-rater reliability: Intraclass correlation coefficient for Understanding = 0.98, Appreciation = 0.97, Reasoning = 0.98, Expressing a choice = 0.91. Internal consistency (Cronbach%26apos;s alpha): Understanding = 0.87, for Appreciation = 0.76, for Reasoning = 0.86. Patients considered to be incapable (gold standard) scored lower in all the MacCAT-T areas. Poor performance on the MacCAT-T was related to cognitive impairment assessed by MMSE. %26lt;br%26gt;Conclusions: Spanish version of the MacCAT-T is feasible, reliable, and valid for assessing the capacity of patients to consent treatment.
