ICF Domain:

Number of Items:

199 Items

Brief Instructions for Administration and Scoring:

Scores are derived by summing sub-scale items; a “percentage achieved” is also calculated for each of the 9 sub-scale’s ranging from 0-100% with higher scores indicating greater independence.

Interpretability:

MCID: not established for SCI
SEM: not established for SCI
MDC: not established for SCI

Languages:

English.

Measurement Property Summary:

# of studies reporting psychometric properties: 2

Reliability:

  • Test-retest reliability of the COPM is Low to High overall (alpha=0.8238) and for the subscales (alpha=0.694-0.904).
  • Internal consistency of the COPM is Low to High overall (alpha=0.83) and for the subscales (alpha=0.6729-0.9467).

[Kennedy et al. 2003, Barry and Kennedy 2002]

Validity:

  • There is High correlation between the NAC ADL with SCIM-II (r = 0.873), the NAC Bladder & Bowel with SCIM-II (r = 0.754), and the NAC Mobility with SCIM-II (r = 0.696)
  • There is High correlation between the NAC psychological issues (mood subsection) with HADS (r = -0.726)
  • There is Moderate to High correlation between the NAC psychological issues (full subscale) with HADS (r = -0.523)
