The MacArthur Competence Assessment Tool for Treatment (MacCAT-T) is the product of an 8-year study of patients' capacities to make treatment decisions. It is a semi-structured interview that assists clinicians in assessing a patient's competence to consent to treatment. The process provides a patient with information about their medical/psychiatric condition, the type of treatment being recommended, its risks and benefits, as well as other possible treatments and their probable consequences. During this process, the MacCAT-T prompts the clinician to ask questions that assess the patient's understanding, appreciation, and reasoning regarding treatment decisions.
The MacCAT-T Manual is a large-format, examiner-friendly field manual for conducting actual competency assessments. The MacCAT-T Record Form is well designed for recording, rating, and summarizing patient responses. The training videotape, Administering the MacCAT-T, demonstrates an actual administration of the test with discussion, comments, and annotations by Drs. Grisso and Appelbaum.
