Participants with Parkinson's disease will be participating in up to 12 one-on-one treatment sessions with 2 sessions per week, for up to 6 weeks. Each session will last 45-60 minutes. During these treatment sessions, each participant will be taught a problem-solving strategy that teaches individuals to monitor and adjust their own actions. Participants will be guided by the principal investigator to select 5 individual treatment goals to work on during treatment. Sessions will continue until all 5 treatment goals have been met or until 12 sessions have been completed, whichever occurs earlier. Initially, each participant's respective primary caregiver will be required to attend treatment sessions, so that the caregiver may be familiar with the treatment strategy in order to coach the participant with Parkinson's disease when you he or she uses the strategy at home.

The COPM is a semi-structured interview focusing on client-centred problem identification that is founded on the Canadian guidelines for client-centred occupational therapy practice and requires approximately 30-40 minutes to administer. The COPM consists of three sections: self-care (basic and instrumental activities of daily living); productivity (education and work); and leisure (play, leisure, and social participation). The assessment begins with self-report of occupational performance issues. The identified occupational performance issues are then rated by the client according to importance on a 10-point Likert scale. The five issues identified as most important to the client are then rated again according to the client's self-determined performance level and satisfaction. Since the COPM is designed to be used as a measure of change, performance and satisfaction levels are scored again after a period of time, (usually during which an intervention has been administered).

The PDQ-39 is the most widely used Parkinson's-specific measure of health-related quality of life. It is a self-administered questionnaire containing thirty nine questions that cover eight aspects of health-related quality of life: mobility (10 items), activities of daily living (6 items), emotional well-being (6 items), stigma (4 items), social support (3 items), cognition (4 items), communication (3 items), and bodily discomfort (3 items). Patients are asked to select the frequency of each problem item occurring over the past month on a 5-point scale (never / occasionally / sometimes / often / always or cannot do at all). The PDQ-39 requires approximately 10-20 minutes to administer.
