Stroke: (Kersey J, Terhorst L, Hammel J, et al, 2022; n = 237)

• MDC for Control subscale of 9 and MDC for Importance subscale of 11 led to achievement of statistically and clinically meaningful changes, suggesting adequate sensitivity to change.

TBI: (Kersey et al., 2021; n = 44; mean age = 49.0 (16.1); age range = 22-90)

• Control Subscale: 2.90
• Importance Subscale: 3.0

TBI: (Kersey et al., 2021)

• Control Subscale: 8
• Importance Subscale: 8

TBI: (Kersey et al., 2021)

• Control Subscale: 5
• Importance Subscale: 5

Predictive validity:

Wheelchair Usage: (Rice et al, 2019; n = 20; mean age = 47(13); 55% male)

• Poor correlation between falls experience and items on Control subscale (r = 0.110)
• Poor correlation between falls experience and items on Importance subscale (r = 0.000)
• Poor correlation between lie time (following a fall) and items on Control subscale (r = -0.192)
• Adequate correlation between lie time (following a fall) and items on Importance subscale (r = -.310)
• Significantly lower CPI scores (mean = 56.70 (17.66) among participants who required assistance to recover compared to participants who were able to recover from a fall independently (mean = 88.93 (22.13), p < 0.05.

Concurrent Validity:

Pulmonary Diseases (COPD): Malaguti et al., 2021; n = 99 w/COPD; mean age = 67(9); 53% (n = 52) male; 27% lived in rural areas)

• Poor negative correlation between CPI and HADS_Anxiety (r = -0.04)
• Poor negative correlation between CPI and HADS_Depression (r = -0.16)
• Poor correlation between CPI and Total Physical Activity (r = 0.28)
• Poor correlation between CPI and Light Intensity Physical Activity (LIPA) (r = 0.26)
• Poor correlation between CPI and Moderate-Vigorous Physical Activity (MVPA) (r = 0.27)

Predictive Validity:

Pulmonary Diseases (COPD): Malaguti et al., 2021)

• Older age and moderate-vigorous physical activity were independent predictors of community participation, explaining 8% of the variance in CPI ratio score [F(_2,85) = 4.51; p = 0.14; R² = 0.075]

Multiple Sclerosis: (Plow et al, 2015; n = 335; mean age = 53.0(10.2); 79.7% female)

• Adequate test-retest reliability over a 2.5-month period (r = 0.84)

Convergent validity:

Multiple Sclerosis: (Plow et al, 2015)

• Significant (p < 0.01) correlations between Community Participation Ratio and:
  • Symptoms of Multiple Sclerosis Scale (r = -0.243)
  • Perceived Deficit Questionnaire (r = -0.354)
  • Stages of change for physical activity (r = 0.225)
  • Emotional management (r = -0.176)
  • Nutritional behaviors (r = 0.159)
  • Craig Hospital Inventory of Environmental Factors-Short Form (CHIEF-SF) (r = -0.308)
  • Self-efficacy self-management symptoms (r = 0.306)

Adequate correlations between subscales of the Enfranchisement scale of the community participation indicators and associated measures (Spearman¡¯s Rho correlations, p < 0.05)

• Adequate correlation with depression items on Importance subscale (r = 0.54)
• Adequate correlation with system, services, policies items on Importance subscale (r = 0.50)
