Purpose

To examine the measurement properties of the Nepali version of the Quick-Disabilities of the Arm, Shoulder and Hand (QuickDASH-NP).

Materials and methods

The Nepali DASH and Shoulder Pain and Disability Index (SPADI) were completed at baseline assessment, and again at follow-up with the Nepali Global Rating of Change (GROC-NP) score. The 11 items of the QuickDASH-NP were extracted from the DASH and tested for confirmatory factory analysis (CFA), exploratory factor analysis (EFA), internal consistency (α), item-total correlation (ITC), test-retest reliability (ICC), measurement errors, hypothesis testing (correlation with DASH and SPADI) and responsiveness (effect size-ES, standardised response mean-SRM).

Results

A total of 156 participants completed questionnaires at baseline and 121 at follow-up with all questionnaires valid (no participant leaving more than one question blank). CFA suggested a poor fit for the single-factor model. The EFA demonstrated two factors with acceptable internal consistency (α = 0.79 and 0.75) for each factor. The test-retest reliability was excellent (ICC = 0.94; 95%CI:0.92–0.98), correlation was positive and very strong with the DASH-NP (r = 0.96) and strong with the SPADI-NP (r = 0.81). The Standard Error of Measurement was 2.83 and Smallest Detectable Change 7.84/100. The ES and SRM were moderate to high.

Conclusions

The QuickDASH-NP is reliable, valid, and able to detect change in shoulder symptoms among Nepali participants. It offers a short, easy to complete self-reporting tool for clinical use and research.

尼泊尔版 Quick-DASH 在肩痛患者中的测量特性

目的

检查尼泊尔版本的手臂、肩部和手部快速残疾 (QuickDASH-NP) 的测量特性。

材料和方法

尼泊尔 DASH 和肩部疼痛和残疾指数 (SPADI) 在基线评估时完成，并在尼泊尔全球变化评级 (GROC-NP) 评分的随访中再次完成。从 DASH 中提取 QuickDASH-NP 的 11 个项目，并进行验证性工厂分析（CFA）、探索性因素分析（EFA）、内部一致性（α）、项目总相关（ITC）、重测信度（ICC）测试。 )、测量误差、假设检验（与 DASH 和 SPADI 的相关性）和反应性（效应大小-ES、标准化反应均值-SRM）。

结果

共有 156 名参与者完成了基线调查问卷和 121 名后续调查问卷，所有问卷均有效（没有参与者留下超过一个问题的空白）。CFA 建议单因素模型拟合不佳。对于每个因素，全民教育证明了两个因素具有可接受的内部一致性（α = 0.79 和 0.75）。重测信度非常好 (ICC = 0.94; 95%CI:0.92–0.98)，与 DASH-NP (r = 0.96) 呈正相关且非常强，与 SPADI-NP (r = 0.81) 相关。测量的标准误差为 2.83，最小可检测变化为 7.84/100。ES 和 SRM 为中到高。

结论

QuickDASH-NP 可靠、有效，并且能够检测尼泊尔参与者肩部症状的变化。它为临床使用和研究提供了一个简短、易于完成的自我报告工具。
