- *Values referred to as Minimally Worthwhile Treatment Effect
(Boswell-Ruys et al. 2010; n=30, 25 males, 5 females; AIS-A/B only; motor level T1-12; mean (SD) 14.5 (12.3) years post-SCI)
- SEM: not established for SCI population
- MDC: not established for SCI population
Reliability – High
Number of studies reporting reliability data: 1
- High internal consistency:
- COPM performance: α = 0.93
- COPM satisfaction: α = 0.89
- High test-retest reliability:
- COPM performance: ICC = 0.99
- COPM satisfaction: ICC = 0.98
(Berardi et al. 2019; n=39, 71% males; mean (SD) age: 53 (15) years; time since injury: 15±14; level of injury: C4-L3)
Validity – Low to Moderate
Number of studies reporting validity data: 3
- Moderate correlation with the COPM subscales and the Functional Independence Measure (FIM) Motor subscale: (r = 0.388-0.514)
(Donnelly et al. 2004; n=41; missing demographic info for 3; 29 males; 18 paraplegia, 20 tetraplegia; 27 complete, 11 incomplete; traumatic and non-traumatic; mean (SD, range) 52 (73.1, 11-364) days post-SCI)
- Low correlation with the COPM and the Klein-Bell ADL Scale: ρ = 0.07
- Low correlation with the COPM and the SCIM III: r = 0.22-0.30, ρ = 0.17-0.30
(Berardi et al. 2019; n=39, 71% males; mean (SD) age: 53 (15) years; time since injury: 15±14; level of injury: C4-L3)
