About this study

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.

Treatment and study plan

Primary outcomes

  1. Factor analysis of the Greek version of the CPGQ

    Time frame: At recruitment (baseline)

  2. Correlations between the CPGQ items, total, subscale scores and the SF-12 PCS, MCS scores

    Time frame: At recruitment (baseline)

  3. Cronbach's alpha values for the total scale and each subscale of the Greek version of the CPGQ

    Time frame: At recruitment (baseline)

  4. Intraclass correlation coefficient (ICC) values for the total scale and each sub scale of the Greek version of the CPGQ

    Time frame: 48 hours

  5. Change in CPGQ total scale and subscale scores

    Time frame: At recruitment (baseline) and 6 months following total hip replacement surgery

    Recruited subjects who will undergo total hip replacement surgery will complete the Greek version of the CPGQ and report their improvement using a dichotomous variable (Yes or No improvement) six months postoperatively.

Secondary outcomes

  1. Percentage of patients who were able to complete the Greek version of the CPGQ by themselves

    Time frame: At recruitment (baseline)

  2. Time employed in filling out the Greek version of the CPGQ

    Time frame: At recruitment (baseline)
