Abstract
Occupational therapy was provided to a prisoner (A) with a developmental disorder and disabilities in interpersonal interaction by considering A’s “thoughts.” Therapy was conducted at the prison, which is a unique environment with many restrictions. The treatment resulted in A being able to undergo job training and guidance reform before being released, and his attitudes and motivation for reform changed remarkably. The factors that facilitated A’s treatment included the occupational therapists’ (OT) individualized and flexible interactions with A as a medical professional, the OT’s search for ways by which A could easily express his thoughts, and the timely sharing of information between OT and the staff in charge of job training and reform guidance through improving recording methods. The factors were facilitated because the OT worked in a section that supported collaboration between staff members.
