Reliability and Validity of the Turkish Version of Work-Related Questionnaire for Upper Extremity Disorders (WORQ-UP)

Area of Science:

• Musculoskeletal Disorders
• Rehabilitation Medicine
• Occupational Health

Background:

• The Work-Related Questionnaire for Upper Extremity Disorders (WORQ-UP) is a patient-reported outcome measure for work-related limitations.
• Upper extremity musculoskeletal disorders significantly impact work capacity.
• A validated Turkish version of the WORQ-UP is needed.

Purpose of the Study:

• To adapt the WORQ-UP into Turkish.
• To evaluate the validity and reliability of the Turkish WORQ-UP.
• To provide a tool for assessing work-related limitations in Turkish-speaking populations.

Main Methods:

• The Turkish WORQ-UP and Turkish Quick DASH were administered to 136 patients.
• Test-retest reliability was assessed over a 7-14 day interval.
• Internal consistency, ICC, Spearman correlation, EFA, and CFA were used for reliability and validity.

Main Results:

• A 12-item Turkish WORQ-UP was developed after excluding items with low item-total score correlation.
• The adapted questionnaire showed high internal consistency (Cronbach's alpha = 0.895) and test-retest reliability (ICC = 0.879).
• Factor analysis confirmed a two-factor structure, and strong correlation with Quick DASH (r = 0.754) supported validity.

Conclusions:

• The 12-item Turkish WORQ-UP possesses adequate psychometric properties.
• It is a valid and reliable tool for identifying work-related limitations in upper extremity musculoskeletal disorders.
• This adapted instrument can be utilized in clinical and research settings for Turkish-speaking individuals.
