To evaluate the measurement properties of the Wheelchair Use Confidence Scale for power wheelchair users (WheelCon-P).
One-month test-retest design, using data from a longitudinal study of power wheelchair use.
Volunteer sample of 73 community dwelling, older adult experienced power wheelchair users who had a mean age of 60.5 ± 7.1 years.
Participants completed the WheelCon-P twice to assess retest reliability. Concurrent validity was assessed by evaluating hypothesized relationships between the WheelCon-P and relevant variables.
The baseline mean (standard deviation) WheelCon-P score was 78.8 ± 14.5. Cronbach's α was 0.92. The one-month test-retest intraclass correlation coefficient was 0.85 (CI 0.77-0.90). Correlations ranging from r = 0.26 (social support) to r = 0.49 (wheelchair skills) were found between the WheelCon-P and the validation outcome measures.
The WheelCon-P has high internal consistency, strong retest reliability and evidence supporting its validity. Although further work is needed, the WheelCon-P may serve as a useful clinical and research tool for measuring power wheelchair confidence. Implications for rehabilitation The WheelCon-P is a reliable and valid outcome measure for assessing wheelchair confidence. This tool can be used to identify individuals with low power wheelchair confidence who require a confidence-enhancing intervention.
评估电动轮椅使用者轮椅使用信心量表（WheelCon-P）的测量属性。
采用为期一个月的重测设计，使用电动轮椅使用纵向研究的数据。
73名居住在社区的老年电动轮椅使用者志愿者样本，平均年龄为60.5±7.1岁。
参与者两次完成WheelCon-P以评估重测信度。通过评估WheelCon-P与相关变量之间的假设关系来评估同时效度。
基线时WheelCon-P的平均（标准差）得分为78.8±14.5。克朗巴哈α系数为0.92。为期一个月的重测组内相关系数为0.85（95%CI 0.77 - 0.90）。WheelCon-P与验证结果指标之间的相关性范围为r = 0.26（社会支持）至r = 0.49（轮椅技能）。
WheelCon-P具有较高的内部一致性、较强的重测信度以及支持其效度的证据。尽管还需要进一步的研究，但WheelCon-P可能是测量电动轮椅信心的一种有用的临床和研究工具。对康复的启示 WheelCon-P是评估轮椅信心的可靠且有效的结果指标。该工具可用于识别电动轮椅信心较低且需要增强信心干预的个体。
