title: Development, reliability, and validity assessment of a fall concerns scale for people who use wheelchairs and scooters (FCS-WC/S)

description: To evaluate the psychometric properties of a Fall Concerns Scale for people who use Wheelchairs and Scooters (FCS-WC/S). 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. 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 (<i>α</i> ≥ 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. 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. Measuring concerns about falling among full-time wheelchair and scooter users is crucial due to its potential negative impact on activity curtailment, which in turn may affect community participation and quality of life.Most validated tools, except for the Spinal Cord Injury-Falls Concern Scale, designed for manual wheelchair users with spinal cord injury, are primarily tailored for individuals who ambulate, highlighting the need for assessment tools specifically designed for full-time wheelchair and scooter users.Using the Spinal Cord Injury-Falls Concern Scale as a foundation, the Fall Concerns Scale for people who use Wheelchairs and Scooters was developed to measure fall concerns among full-time wheelchair and scooter users, irrespective of their specific health conditions.The Fall Concerns Scale for people who use Wheelchairs and Scooters has a good potential to offer clinicians a valid and reliable tool to systematically screen fall concerns across various health conditions, with further large-scale studies needed to validate the tool across a wider range of health conditions.
