PURPOSE: To evaluate the psychometric properties of a Fall Concerns Scale for people who use Wheelchairs and Scooters (FCS-WC/S).
MATERIALS AND METHODS: Developed by fall prevention experts, FCS-WC/S underwent refinement through interdisciplinary reviews and focus groups with researchers, clinicians, and individuals who use WC/S full-time. The psychometric evaluation involved adults who used WC/S for ≥1 year and had ≥1 fall in the previous 3 years, recruited between April and September 2022.
RESULTS: The FCS-WC/S evaluates fall concerns among people with various health conditions who use WC/S full-time across 33 daily activities. One hundred and twenty-four participants responded to the baseline survey. A subgroup of 63 people repeated the FCS-WC/S a week later. The FCS-WC/S demonstrated excellent internal and good test-retest reliability (α ≥ 0.90, ICC = 0.86-0.9), as well as concurrent validity (Spearman's rho = 0.72) with the Spinal Cord Injury Falls Concern Scale (SCI-FCS). It effectively differentiated fear of falling levels from an established measure (ORs 4.1, 25.8, 46.7). Factor and parallel analysis revealed three factors, two of which were retained for further analysis.
CONCLUSIONS: Preliminary findings support FCS-WC/S validity and reliability for assessing fall concerns among individuals with various conditions who use WC/S. Further scale construction analysis is recommended.
