Summary
The Upper Extremity Questionnaire demonstrates good to excellent reliability for most items in workers. However, symptom severity and work interference reports were less stable, with demographic factors not significantly impacting reliability.
Area of Science:
- Occupational Health
- Epidemiology
- Psychometrics
Background:
- Limited validation of questionnaires in working populations.
- The Upper Extremity Questionnaire (UEQ) is a self-administered tool for epidemiological studies.
- This study evaluates the reliability of the UEQ in a worker cohort.
Purpose of the Study:
- To assess the test-retest reliability of the Upper Extremity Questionnaire.
- To identify factors influencing the reliability of the UEQ items.
Main Methods:
- Two-part assessment of 138 keyboard operators.
- Reliability analysis using kappa statistic, paired t-test, and intraclass correlation coefficient (ICC).
- Logistic regression to evaluate demographic and work-related factors' impact on reliability.
Main Results:
- Overall symptom reports showed stability (kappa 0.60-0.89).
- Hand diagram reliability varied (right: 0.57, left: 0.28).
- Perceived Stress and Job Dissatisfaction Scales showed high reliability (ICC=0.88), co-worker support was low (ICC=0.44).
Conclusions:
- The UEQ generally exhibits good to excellent reliability for its items.
- Symptom severity and work interference reporting demonstrated lower stability.
- Demographic and work-related factors did not significantly affect UEQ reliability.
