Abstract

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.
