Overview

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.

Outcomes

Primary Outcomes

Internal Consistency of the Turkish Pictorial Pain Interference Questionnaire

Internal consistency will be assessed using Cronbach's alpha coefficient.

Time frame: At the first assessment (Baseline)

Test-Retest Reliability of the Turkish Pictorial Pain Interference Questionnaire

Test-retest reliability will be assessed using the Intraclass Correlation Coefficient (ICC) based on assessments performed 7 days apart.

Time frame: Baseline and 7 days

Construct Validity of the Turkish Pictorial Pain Interference Questionnaire

Construct validity will be evaluated by examining the correlations between the questionnaire scores and scores from the Brief Pain Inventory.

Time frame: Baseline

Construct Validity of the Turkish Pictorial Pain Interference Questionnaire

Construct validity will be evaluated by examining the correlations between the questionnaire scores and scores from the Pain Disability Index.

Time frame: Baseline

Construct Validity of the Turkish Pictorial Pain Interference Questionnaire

Construct validity will be evaluated by examining the correlations between the questionnaire scores and scores from the Oswestry Disability Index.

Time frame: Baseline

Construct Validity of the Turkish Pictorial Pain Interference Questionnaire

Construct validity will be evaluated by examining the correlations between the questionnaire scores and scores from the Short-Form McGill Pain Questionnaire.

Time frame: Baseline

Secondary Outcomes

Discriminant Validity of the Turkish Pictorial Pain Interference Questionnaire

Discriminant validity will be assessed by examining correlations with concepts expected to have weak associations with pain, including positive affect.
