The Needs Assessment Checklist (NAC) is an interview-based assessment, measuring patient perception of independence in a range of tasks from 9 SCI-specific rehabilitation domains: activities of daily living (ADL, 29 items), skin management (14 items), bladder management (10), bowel management (7), mobility (17), wheelchair and equipment (33), community preparation (24), discharge coordination (32) and psychological issues (19).
ICF Domain
Activities ▶ Self Care
Administration
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.

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; Berry 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).
(Berry and Kennedy 2002)
Responsiveness
No values were reported for the responsiveness of the NAC for the SCI population at this time.
Floor/Ceiling Effect
No values were reported for the presence of floor/ceiling effects in the NAC for the SCI population.
