Abstract

Introduction: Using Boston questionnaire (BQ) is common to evaluate the severity and functional ability in patients with carpal tunnel syndrome (CTS). This study aimed to translate and adapt the Persian version of BQ for the assessment of the severity and investigation of its validity and reliability. Materials and Methods: BQ has two parts: first part with 11 questions evaluates the severity of symptoms (BQ-SS) and the other part with 8 questions evaluates the functional status (BQ-FS) of patients. After translation and preparing the Persian version of BQ by two translators, it has been re-translated to English and matched to the original. For content and construct validity evaluation, the opinions of 15 patients with CTS and 20 specialist medical doctors were used. They were asked to complete the final Persian version of BQ. To investigate the reliability, 45 CTS patients (age ranged 20-60 years old, 86 affected wrists) in two groups low-literate and literate, completed Persian BQ in two different sessions with at least 2 weeks interval for each affected hand. Results: Using Cronbach's alpha, showed excellent internal consistency for both literate (BQ-SS= 0.88, BQ-FS= 0.90) and low-literate (BQ-SS= 0.90, BQ-FS= 0.90) subjects. The intraclass correlation oefficients were also excellent in both literate (BQ-SS= 0.834, P
