EMPOWER PD - Feasibility of an Interdisciplinary Clinic for People With Parkinson's Disease

Feasibility is measured by attendance and retention and survey completion rates. Attendance reported for each component of the clinic (clinic, seminar, 1:1 meeting, and follow-up interview). Retention reflects the number of participants that participated in all 4 components. Survey completion rates reflect the number of participants that completed all self report measures at Baseline and End of Study.

A series of 12 statements regarding acceptability, process, barriers, and perception of experience of clinic will be scored by participants on a scale of 1 (disagree) to 5 (agree) with a higher score on each statement indicating more positive outcome. The average response per question is reported below.

Parkinson's Disease (PCOQ-PD) The PCOQ-PD evaluates treatment success and expectations from the patient's perspective across 10 motor and non-motor functional domains grouped into four sections. Patients are asked to rate for each domain with each section: (1) their usual levels of self-defined difficulty over the past week, (2) their success criteria for treatment outcomes, (3) their expectations for their treatment, regardless of their previous treatment experiences, and (4) how important it was for them to see improvement. Participants used a 101-point numerical rating scale to indicate their rating, anchored by 0 ("None") to 100 ("Worst Imaginable") for the first three sections and by 0 ("Not at All Important") to 100 ("Most Important") for the fourth section. The mean response and standard deviation are reported below.

Knowledge regarding Parkinson's disease as measured by the Parkinson's Disease Knowledge Questionnaire (PDKQ). Participants indicate their knowledge of 26 items related to Parkinson's disease with a true or false response.

Subjects score 42 items across 8 domains using a Likert-style question format indicated their strength of agreement by checking an option from 1 ("strongly disagree") through 5 ("strongly agree").

Self-Efficacy for Exercise scale consists of nine situations (weather, boredom, exercising alone, not pleasurable, too busy, feel tired, stress, depressed) that might effect participation in exercise For each situation, the subject uses the scale from 0 (not confident) to 10 (very confident) to describe their current confidence that they could exercise 3 times a week for 20 minutes each time. Total score is calculated by summing the responses to each question. This scale has a range of total scores from 0-90. A higher score indicates higher self-efficacy for exercise. Participants total score was then divided by 90 to convert to a percentage.

The ABC is The ABC is an 16 question survey and ratings should consist of whole numbers (0-100) for each item. Total the ratings (possible range = 0 - 1600) and divide by 16 to get each subject's ABC score which is a percentage of agreement out of 100%.

The PDQ-39 is a 39-item self-report questionnaire, which assesses Parkinson's disease-specific health related quality over the last month covering 8 dimensions scored on a 5 point ordinal system (0=never, 4=always). Dimension score = sum of scores of each item in the dimension divided by the maximum possible score of all the items in the dimension, multiplied by 100. Each dimension total score range from 0 (never have difficulty) to 100 (always have difficulty). Lower scores reflect better QoL. Overall score can be summarized in the Parkinson's Disease Summary Index (PDSI) or PDQ-39 Summary Index (PDQ-39 SI).PDSI or PDQ-39 SI = sum of dimension total scores divided by 8 which then reflects a mean score ranging from 0 to 19.5 with a lower number reflecting better quality of life.

The PFS-16 is a 16-item patient rated scale based on feelings and experiences over the past two weeks. Seven items tap the presence or absence of the subjective experience of fatigue with an emphasis on the physical effects of fatigue and nine items address the impact of fatigue on daily functioning and activities, including socialization and work but not exercise specifically. Scoring options range from 1 ("strongly disagree") to 5 (strongly agree"). A total ordinal PFS score ranging from 16-80 based on the sum of the scores will be used.
