OBJECTIVE
To test a 17-item questionnaire, the WOrk-Related Questionnaire for UPper extremity disorders (WORQ-UP), for dimensionality of the items (factor analysis) and internal consistency.
DESIGN
Cross-sectional study.
SETTING
Outpatient clinic.
PARTICIPANTS
A consecutive sample of patients (N=150) consisting of all new referral patients (either from a general physician or other hospital) who visited the orthopedic outpatient clinic because of an upper extremity musculoskeletal disorder.
INTERVENTIONS
Not applicable.
MAIN OUTCOME MEASURES
Number and dimensionality of the factors in the WORQ-UP.
RESULTS
Four factors with eigenvalues (EVs) >1.0 were found. The factors were named exertion, dexterity, tools & equipment, and mobility. The EVs of the factors were, respectively, 5.78, 2.38, 1.81, and 1.24. The factors together explained 65.9% of the variance. The Cronbach alpha values for these factors were, respectively, .88, .74, .87, and .66.
CONCLUSIONS
The 17 items of the WORQ-UP resemble 4 factors-exertion, dexterity, tools & equipment, and mobility-with a good internal consistency.
目的
测试一个 17 项的问卷，即工作相关的上肢疾病问卷（WORQ-UP），以检验项目的维度（因子分析）和内部一致性。
设计
横断面研究。
地点
门诊。
参与者
连续样本的患者（N=150），包括所有因上肢肌肉骨骼疾病而从普通医生或其他医院转诊到骨科门诊的新就诊患者。
干预措施
不适用。
主要观察指标
WORQ-UP 的项目数量和维度。
结果
发现了 4 个特征值（EV）>1.0 的因子。这些因子分别命名为用力、灵巧性、工具和设备以及活动度。各因子的 EV 值分别为 5.78、2.38、1.81 和 1.24。这些因子共同解释了 65.9%的方差。这些因子的 Cronbach alpha 值分别为.88、.74、.87 和.66。
结论
WORQ-UP 的 17 项内容类似于 4 个因子，即用力、灵巧性、工具和设备以及活动度，具有良好的内部一致性。
