The need for validated outcome measures is increasing. The purpose is to translate and validate the Patient Rated Wrist Evaluation (PRWE) in Danish. Translation was done by an expert panel followed by evaluation of a lay panel and a field test on 10 patients. Sixty patients with wrist fractures were included. Both lay panel comments and field test revealed issues not dealt with by the expert panel, and a final version of the Danish PRWE was made. The validation process then continued and reliability results. were presented as Cronbach's alpha = 0.94, describing the homogeneity and the intraclass correlation coefficient = 0.88 and difference of mean = 5.7 (CI = 1.12-10.37, p = 0.017), describing the concordance of the results. Convergent validity at first and last control was for pain, 0.51 and 0.46, and physical mobility, 0.56 and 0.64, respectively, describing the correlation with a gold standard questionnaire. A minor floor effect was noticed, but not enough to indicate a lack of sensitivity of the PRWE. Effect size, the ability to measure sensitivity to change, was 0.62, also described as responsiveness. The translation resulted in a questionnaire that represents correct easy-understandable Danish. It is concluded that the modified Danish version is a valid questionnaire for patients with wrist fractures.
对经过验证的结果测量指标的需求日益增加。目的是将患者自评腕关节评估量表（PRWE）翻译成丹麦语并进行验证。由一个专家小组进行翻译，随后由一个外行小组进行评估，并对10名患者进行现场测试。纳入了60名腕部骨折患者。外行小组的意见和现场测试都揭示了专家小组未处理的问题，于是形成了丹麦语PRWE的最终版本。然后继续进行验证过程并给出可靠性结果。克朗巴哈系数α = 0.94，描述了同质性；组内相关系数 = 0.88，平均差异 = 5.7（置信区间 = 1.12 - 10.37，p = 0.017），描述了结果的一致性。首次和末次对照时的收敛效度，疼痛方面分别为0.51和0.46，身体活动方面分别为0.56和0.64，描述了与金标准问卷的相关性。发现有轻微的地板效应，但不足以表明PRWE缺乏敏感性。效应大小，即测量对变化敏感性的能力，为0.62，也称为反应性。翻译后的问卷能用正确且易懂的丹麦语表述。结论是，修改后的丹麦语版本对于腕部骨折患者是一个有效的问卷。
