After translation and cultural adaptation according to the Beaton method (approved by the American Surgeon Association), the pilot test was performed on patients with wrist injuries (fractures of the distal radius, scaphoid fractures and carpal tunnel syndrome). To assess content and face validity, the questionnaire was given to 10 specialists (6 of whom were occupational therapists, 2 were physiotherapists, and 2 were orthopaedic surgeons), and 20 patients with wrist injuries.
The qualitative content and face validity of the questionnaire for wrist injuries was appropriately reported good. Each item of the content validity ratio was slightly higher than 0.75 and this justified the necessity to include all items. Each item of the content validity index was slightly higher than 0.79. Therefore, all the items were approved in terms of their simplicity, clarity, and relevance.
