The Greek Version of the Chronic Pain Grade Questionnaire (CPGQ)

Validity, Reliability and Responsiveness of the Greek Version of the Chronic Pain Grade Questionnaire (CPGQ) in Chronic Hip Pain Sufferers

The aim of the present study is to investigate and report on the psychometric properties of a Greek version of the Chronic Pain Grade Questionnaire (CPGQ).

Study Overview

• Status: Completed
• Conditions: Chronic Hip Pain

Detailed Description

The Chronic Pain Grade Questionnaire (CPGQ) is designed to evaluate overall severity of chronic pain based on two dimensions, pain intensity and pain-related disability. Currently, there is no reliable, valid and sensitive to change self-report instrument as brief and easy to understand and complete as the CPGQ available in Greek. A culturally adapted version of the CPGQ would facilitate the study of chronic pain and its implications in the Greek population and allow for cross-cultural comparisons. The aim of the present study is to examine the validity, reliability and responsiveness of a Greek version of the CPGQ in chronic hip pain sufferers.
