The goal of this study was to develop a reliable and valid tool for quantifying patient-rated wrist pain and disability.
Survey, tool development, reliability, and validity study.
Upper extremity unit.
One hundred members of the International Wrist Investigators were surveyed by mail to assist in development of the scale. Patients with distal radius (n = 64) or scaphoid (n = 35) fractures were enrolled in a reliability study, and 101 patients with distal radius fractures were enrolled in a validity study.
Information from the expert survey, biomechanical literature, and patient interviews was used as a basis for item generation and definition of structural limitations for a scale that would be practical in the clinic. Patients with distal radius or scaphoid fractures completed the Patient-Rated Wrist Evaluation (PRWE) on two occasions to determine test-retest reliability. Patients with distal radius fractures (n = 101) completed the PRWE and the SF-36 and were tested with traditional impairment measures at baseline and at two, three, and six months after fracture to determine construct and criterion validity.
Reliability coefficients (ICCs) and validity correlations (Pearson product moment correlations).
Patient opinions on pain and on ability to do activities of daily living and work were thought to be the most important dimensions to include in subjective outcome tools. Brevity and simplicity were seen as essential in the clinic environment. A fifteen-item questionnaire (the PRWE) was designed to measure wrist pain and disability. Test-retest reliability was excellent (ICCs > 0.90). Validity assessment demonstrated that the instrument detected significant differences over time (p < 0.01) and was appropriately correlated with alternate forms of assessing parameters of pain and disability.
The PRWE provides a brief, reliable, and valid measure of patient-rated pain and disability.

调查、工具开发、可靠性和有效性研究。
上肢科。
通过邮件对100名国际腕关节研究人员进行了调查，以协助量表的开发。纳入64例桡骨远端骨折或35例舟骨骨折患者进行可靠性研究，纳入101例桡骨远端骨折患者进行有效性研究。
专家调查、生物力学文献和患者访谈所得信息被用作生成条目的基础，并为临床实用的量表定义结构限制。桡骨远端或舟骨骨折患者两次完成患者自评腕关节评估（PRWE）以确定重测信度。桡骨远端骨折患者（n = 101）完成PRWE和SF-36，并在骨折后基线、2个月、3个月和6个月时采用传统损伤测量方法进行测试，以确定结构效度和效标效度。
信度系数（组内相关系数）和效度相关性（Pearson积矩相关性）。
患者对疼痛以及进行日常生活和工作能力的看法被认为是主观结局工具中最重要的维度。在临床环境中，简洁性被视为至关重要。设计了一份包含15个条目的问卷（PRWE）来测量腕部疼痛和功能障碍。重测信度极佳（组内相关系数> 0.90）。效度评估表明，该工具随时间检测到显著差异（p < 0.01），并且与评估疼痛和功能障碍参数的其他形式适当相关。
PRWE提供了一种简短、可靠且有效的患者自评疼痛和功能障碍测量方法。
