Pilot test
Once the translated instrument was developed, a pilot study using subjects selected from the target population was undertaken to test the psychometric properties of equivalency,
reliability and score distribution. The translated version was piloted among 30 patients. Changes in wording recommended by the patients were incorporated in the final version of the tool. The reliability and the construct validity of the Turkish version of the SF-MPQ did not indicate any problematic items in this preliminary testing. Therefore, additional investigations to assess the psychometric performance of the Turkish version of the SF-MPQ were undertaken.
