Reliability and Validity of the Turkish Version of the 6-item Carpal Tunnel Syndrome Symptoms Scale
Study Details
Study Description
Brief Summary
Carpal tunnel syndrome (CTS) is a common condition that affects the median nerve that usually cause numbness, tingling, pain, and weakness in the hand and fingers. While definitive diagnosis is made with nerve conduction studies, the patient's history and physical examination findings lead the clinician to the diagnosis of CTS. Using factor analysis and item response theory methodology, Atroshi et al. developed a short 6-item version of the symptom severity scale to ease respondent burden while maintaining the psychometric properties of the Boston Carpal Tunnel Questionnaire. It has been demonstrated that the 6-item CTS Symptom Scale has good reliability, validity and responsiveness.
The aim of this study was to evaluate the reliability and construct validity of the Turkish version of the 6-item CTS symptoms scale for CTS.

Detailed Description
Carpal tunnel syndrome (CTS) is a common condition that affects the median nerve that usually cause numbness, tingling, pain, and weakness in the hand and fingers. While definitive diagnosis is made with nerve conduction studies, the patient's history and physical examination findings lead the clinician to the diagnosis of CTS. The use of patient-completed disease-specific scales is increasing in clinical research and patient follow-up. Various scales have been developed to question symptoms related to hand problems. The Boston Carpal Tunnel Questionnaire and the 6-item CTS Symptom Scale are the scales that have been shown to be used to assess symptom severity and for diagnostic screening. Using factor analysis and item response theory methodology, Atroshi et al. developed a short 6-item version of the symptom severity scale to ease respondent burden while maintaining the psychometric properties of the Boston Carpal Tunnel Questionnaire . It has been demonstrated that the 6-item CTS Symptom Scale has good reliability, validity and responsiveness.
The aim of this study was to evaluate the reliability and construct validity of the Turkish version of the 6-item CTS symptoms scale for CTS.
Study Design
Outcome Measures
Primary Outcome Measures
- 6-item CTS Symptom Scale (CTS-6) [baseline]
The CTS-6 is a scale designed to measure the severity of CTS symptoms. It consists of six items, five of which are similar to those on the symptom severity subscale of the Boston CTS Scale, while the sixth item is a combination of two items from the same subscale.
- Boston Carpal Tunnel Questionnaire (BCTQ) [baseline]
The BCTQ consists of two subscales, the Symptom Severity Scale and the Functional Status Scale. The Functional Status Scale contains eight items assessing activities such as "writing, buttoning clothes, holding a book while reading, grasping a telephone handle, opening a jar, doing housework, carrying grocery bags, bathing and dressing" whereas the 11-item Symptom Severity Scale assesses pain, paresthesia, numbness, weakness, nocturnal symptoms and grip difficulty.
- The Michigan Hand Outcomes Questionnaire (MHQ) [baseline]
MHQ is a standardized instrument designed to quantify outcomes in patients with a range of hand conditions. The MHQ consists of 6 subscales: hand function, activities of daily living, pain, satisfaction, aesthetics and work performance. A cumulative score is calculated to provide an indication of overall function.
