To study the psychometric qualities of a perceived self-efficacy in wheeled mobility scale.
Questionnaires.
Forty-seven wheelchair basketball players with spinal cord injury (elite n=25, recreational n=22, from 6 different countries).
Based on the literature, and expert's and wheelchair user's comments, a new Self-Efficacy in Wheeled Mobility Scale (SEWM)1 was developed. Internal consistency (split-half and Cronbach's alpha) and concurrent validity (correlating the Self-Efficacy in Wheeled Mobility Scale with the Generalized Perceived Self-efficacy Scale (GSE) and the spinal cord injury Exercise Self-Efficacy Scale (ESES)) were assessed. To evaluate the construct validity, age, lesion level and completeness and time since injury between groups of participants and their total scores were compared statistically.
Cronbach's alpha for the SEWM was 0.91, internal consistency was r=0.90. Significant correlations between pairs of scales of the entire sample (SEWM-ESES: 0.60; SEWM-GSE: 0.50 (p<0.05; n= 47, 2-tailed) and of the sub-group comparison (SEWM-ESES recreational r=0.61; elite r=0.73), demonstrated fair construct and concurrent validity of the SEWM.
The SEWM was found to be reliable and valid in active spinal cord injury. A larger more diverse sample is needed to support the psychometric qualities of the SEWM scale.
研究轮椅移动感知自我效能感量表的心理测量学质量。
问卷调查。
47 名脊髓损伤的轮椅篮球运动员（精英组 n=25，娱乐组 n=22，来自 6 个不同的国家）。
根据文献，以及专家和轮椅使用者的意见，开发了一种新的轮椅移动感知自我效能感量表（SEWM）1。评估内部一致性（分半信度和克朗巴赫α）和同时效度（将自我效能感量表与广义感知自我效能感量表（GSE）和脊髓损伤运动自我效能感量表（ESES）相关联）。为了评估结构效度，对参与者的年龄、损伤水平和损伤的完全性以及伤后时间进行了统计比较。
SEWM 的克朗巴赫α为 0.91，内部一致性为 r=0.90。整个样本的量表对之间存在显著相关性（SEWM-ESES：0.60；SEWM-GSE：0.50（p<0.05；n=47，双尾）和亚组比较（SEWM-ESES 娱乐组 r=0.61；精英组 r=0.73），表明 SEWM 的结构和同时效度良好。
在活跃的脊髓损伤中，SEWM 被发现是可靠和有效的。需要更大、更多样化的样本来支持 SEWM 量表的心理测量学质量。
