This study compared the reliability, validity, and responsiveness of self-reported measures of health related quality of life in recipients and non-recipients of workers' compensation who have carpal tunnel syndrome.
Patients with carpal tunnel syndrome complete questionnaires at study enrollment and 6 months later scales measuring symptom severity functional status, and satisfaction were included. The scales internal consistency, validity, and responsiveness were assessed.
The internal consistencies for each scale were high (Cronbach's alpha .88 to .96) and virtually identical in recipients and nonrecipients of workers' compensation. The correlations between self-reported and objectively measured grip strength were .32 in recipients and .30 in nonrecipients; these correlations were not influenced by whether workers' compensation recipients were out of work. Correlations between changes in scale scores and three indicators of perceived improvement were higher in recipients (.48 to .69) than in nonrecipients (.19 to .41)
The reliability, validity, and responsiveness of these measures were comparable in nonrecipients and recipients of workers compensation, these data support the use of self-report measures in studies of workers.
本研究比较了患有腕管综合征的工伤赔偿接受者和非接受者自我报告的健康相关生活质量测量指标的可靠性、有效性和反应性。
患有腕管综合征的患者在研究入组时及6个月后完成问卷调查，纳入测量症状严重程度、功能状态和满意度的量表。评估量表的内部一致性、有效性和反应性。
每个量表的内部一致性都很高（克朗巴赫α系数为0.88至0.96），在工伤赔偿接受者和非接受者中几乎相同。自我报告的握力与客观测量的握力之间的相关性在接受者中为0.32，在非接受者中为0.30；这些相关性不受工伤赔偿接受者是否失业的影响。量表分数变化与感知改善的三个指标之间的相关性在接受者中（0.48至0.69）高于非接受者（0.19至0.41）。
这些测量指标的可靠性、有效性和反应性在工伤赔偿非接受者和接受者中具有可比性，这些数据支持在工伤工人研究中使用自我报告测量指标。
