Interpretability
Higher scores indicate higher levels of participation.
MCID: not established in SCI
SEM: not established in SCI
MDC: not established in SCI
Typical Values
Mean (SD) Scores:
- Frequency: 34.2 (12.2)
- Restrictions: 70.0 (21.7)
- Satisfaction: 69.3 (18.0)
(Mader et al. 2016; n=1549; 1107 males, 442 females; injury level: 474 tetraplegia, 1063 paraplegia; 646 complete, 894 incomplete injury; mean (SD) time post-SCI = 16.9 (12.7) years)
Reliability – Moderate to High
Internal consistency is Moderate to High:
- USER-P Frequency: α = 0.51 – 0.70
- USER-P Restrictions: α = 0.89 – 0.91
- USER-P Satisfaction: α = 0.78 – 0.90
(Mader et al. 2016; n=1549; 1107 males, 442 females; injury level: 474 tetraplegia, 1063 paraplegia; 646 complete, 894 incomplete injury; mean (SD) time post-SCI = 16.9 (12.7) years)
(van der Zee et al. 2014; n=157; 104 males, 53 females; 69.4% complete injury; mean (SD) time post-SCI = 25.3 (26.8) years)
(Post et al. 2012; n=395; 211 males, 184 females; participants with MSK disease, TBI, stroke, neuromuscular disease (such as SCI), chronic pain, and heart failure)
Validity – Moderate to High

- USER-P Satisfaction: rs = -0.52
(van der Zee et al. 2014; n=157; 104 males, 53 females; 69.4% complete injury; mean (SD) time post-SCI = 25.3 (26.8) years)
- Moderate to High correlation with Frenchay Activities Index (FAI):
- USER-P Frequency: rs = 0.59
- USER-P Restrictions: rs = 0.51

- USER-P Frequency: rs = -0.40
- USER-P Restrictions: rs = -0.71
- USER-P Satisfaction: rs = -0.73
(Post et al. 2012; n=395; 211 males, 184 females; participants with MSK disease, TBI, stroke, neuromuscular disease (such as SCI), chronic pain, and heart failure)
Responsiveness
