Official Title

Turkish Cultural Adaptation and Psychometric Properties of the Pain and Smoking Inventory in Individuals With Chronic Pain

Brief Summary

The purpose of this study is to perform the Turkish cross-cultural adaptation of the Pain and Smoking Inventory (PSI) and to comprehensively evaluate its reliability, validity, and psychometric properties among daily cigarette smokers with chronic pain.

Detailed Description

This methodological and cross-sectional study consists of two primary phases: (1) the cross-cultural adaptation of the Pain and Smoking Inventory (PSI) into Turkish, and (2) the evaluation of the psychometric properties, reliability, and validity of the Turkish version (PSI-TR). The study will be conducted at the Bingöl University Faculty of Physical Therapy and Rehabilitation and the Bingöl State Hospital Physical Medicine and Rehabilitation Outpatient Clinic. Data collection will be carried out using printed forms and an online survey platform (Kobotoolbox).

Translation and Cultural Adaptation Process

The cultural adaptation process of the PSI will be performed in accordance with the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) guidelines. The process involves five distinct stages:

Forward translation from English to Turkish by two independent translators. A reconciliation meeting to merge the translations into a single synthesis version.

Backward translation of the synthesized version into English by two independent translators who are blind to the original scale.

Review of the backward translation by the original scale developer. A pilot test with 10 individuals to assess semantic clarity and comprehensibility before finalization.
