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 ( ≥ 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.
评估轮椅和踏板车使用者跌倒担忧量表（FCS-WC/S）的心理测量特性。
FCS-WC/S由跌倒预防专家开发，通过跨学科评审以及与研究人员、临床医生和全职使用轮椅和踏板车的个体进行焦点小组讨论进行完善。心理测量评估纳入了在2022年4月至9月期间招募的成年轮椅和踏板车使用者，这些使用者使用轮椅和踏板车≥1年且在过去3年中至少有过1次跌倒。
FCS-WC/S评估了全职使用轮椅和踏板车的各种健康状况人群在33项日常活动中的跌倒担忧。124名参与者完成了基线调查。其中63人组成的一个亚组在一周后再次进行了FCS-WC/S评估。FCS-WC/S显示出优异的内部一致性和良好的重测信度（≥0.90，组内相关系数ICC = 0.86 - 0.9），以及与脊髓损伤跌倒担忧量表（SCI-FCS）的同时效度（斯皮尔曼相关系数rho = 0.72）。它能有效地将跌倒恐惧水平与既定测量方法区分开来（比值比分别为4.1、25.8、46.7）。因子分析和平行分析揭示了三个因子，其中两个因子被保留用于进一步分析。
初步研究结果支持FCS-WC/S在评估使用轮椅和踏板车的各种状况个体跌倒担忧方面的效度和信度。建议进一步进行量表构建分析。
