| OUTCOME | DESCRIPTION AND PROPERTIES | TIMING |
|---|---|---|
| Performance Quality Rating Scale (PQRS) |
The PQRS rates video recorded performance of participant-selected activities on a 10-point scale, with a score of 1 indicating “can’t do the skill at all” and 10 indicating “does the skill very well”.15 The activities performed and video recorded are determined using the COPM, and most, but not all, goals selected by participants are amenable to video recording. The PQRS has substantial test-retest reliability and good internal responsiveness.26 |

| Canadian Occupational Performance Measure (COPM) |
The COPM is a standardized instrument for eliciting performance issues from the client perspective, and for capturing perceived changes in performance over time.25 The COPM was used to elicit 4–6 participant-selected goals, as well as for rating self- perceived performance and performance satisfaction for each goal on a 10-point scale, for each participant. The COPM has demonstrated test-retest reliability of 0.89 in people with stroke.27 A change of 2 points or more on the COPM is considered clinically significant.25 |

| Community Performance Indicators (CPI) |
The CPI is a complex self-report measure of community participation. In this study, we analyzed two enfranchisement factors, importance of participation (14 items) and control over participation (13 items). Participants rate items on a 5 point scale, which are converted using a Rasch-based key form to a score of 0- 100 28,29 There is good evidence of validity and reliability for these factors. |
Times 2 & 3 |
| Stroke Impact Scale (SIS) |
The SIS30 is a 59-item questionnaire based measure of the perceived impact of stroke on function and everyday life. The SIS evaluates eight domains including participation. Each item is scored on a 5-point Likert scale related to the degree of difficulty the person with stroke is experiencing. The SIS is widely used in stroke intervention studies as an outcome measure and the psychometric properties of the instrument are well- defined.30–32 |

| Self-Efficacy Gauge (SEG) |
The SEG was designed to measure an individual’s confidence in his or her ability to perform daily occupations that span a range of self-care, productivity, and leisure activities. Participants are asked to rate their confidence in their ability to perform 28 items, each on a 10-point scale, with 1 representing “not confident at all” and 10 representing “completely confident”. The SEG has very high internal consistency (0.94) and test-retest reliability (0.90).33 |
