Cross-sectional design.
This study examined the translated English to Polish version of the Patient-Rated Ulnar Nerve Evaluation (PRUNE) for its internal consistency, test-retest reliability, and construct validity.
During the first assessment validity testing, a total of 39 consecutive patients with cubital tunnel syndrome completed the PRUNE, Michigan Hand Outcome Questionnaire, Disabilities of the Arm, Shoulder, and Hand questionnaire, and Patient Evaluation Measure in conjunction with the grip and key pinch tests and pain score (by Visual Analogue Scale). Cronbach's alpha (CA), intraclass correlation coefficient (ICC), and the Bland-Altman plot were used to evaluate internal consistency, test-retest reliability, and agreement, respectively. Analysis of variance compared the PRUNE score with the McGowan clinical stages.
After a 1-day interval, 19 patients completed the PRUNE for the second time. The total PRUNE score was 44.4 ± 20.4, CA = 0.93, and ICC = 0.921. The total PRUNE score limits of agreement varied from -9.87 to 7.55 points. PRUNE subscale CA ranged from 0.79 to 092; the ICC varied from 0.738 to 0.911. The construct validity revealed a strong association with Michigan Hand Outcome Questionnaire (R = -0.83; P < .000), and moderate with Disabilities of the Arm, Shoulder, and Hand (R = 0.75; P < .000), Patient Evaluation Measure (R = 0.75; P < .000), and Visual Analogue Scale (R = 0.69; P < .000). The grip and pinch tests had low and no correlation with the total PRUNE score, respectively.
The Polish version of PRUNE showed good psychometric properties for use in both clinical and research practice in patients with cubital tunnel syndrome of varying intensity.
横断面设计。
本研究旨在检验经翻译后的波兰语版患者尺神经评估量表(PRUNE)的内部一致性、重测信度和结构效度。
在首次评估有效性测试中,共 39 例肘管综合征患者完成了 PRUNE、密歇根手功能问卷、上肢功能障碍问卷、患者评估量表,并结合握力和捏力测试以及疼痛评分(视觉模拟评分)进行了测试。采用克朗巴赫系数(CA)、组内相关系数(ICC)和 Bland-Altman 图分别评估内部一致性、重测信度和一致性。方差分析比较了 PRUNE 评分与 McGowan 临床分期。
1 天后,19 例患者再次完成 PRUNE。PRUNE 总评分 44.4±20.4,CA=0.93,ICC=0.921。PRUNE 总分的一致性界限从-9.87 到 7.55 分不等。PRUNE 分量表的 CA 范围为 0.79 到 0.92;ICC 范围为 0.738 到 0.911。结构效度显示与密歇根手功能问卷(R=-0.83;P<0.000)有很强的关联,与上肢功能障碍问卷(R=0.75;P<0.000)、患者评估量表(R=0.75;P<0.000)和视觉模拟评分(R=0.69;P<0.000)有中度关联。握力和捏力测试与 PRUNE 总分的相关性较低或无相关性。
波兰语版 PRUNE 具有良好的心理测量学特性,可用于不同严重程度肘管综合征患者的临床和研究实践。
