Turkish Version of the Pictorial Pain Interference Questionnaire

This study aims to culturally adapt the Pictorial Pain Interference Questionnaire into Turkish and evaluate its psychometric properties in individuals with chronic pain. The study will assess the validity and reliability of the Turkish version for evaluating the functional impact of chronic pain on daily life activities. Reliability will be examined through internal consistency and test-retest reliability, while validity will be assessed by examining the relationships between the questionnaire and established pain-related assessment tools. The study will determine whether the Turkish version provides a valid, reliable, and practical instrument for assessing functional interference associated with chronic pain in Turkish-speaking individuals.
