Brief summary

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).

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.

Design outcomes

Primary

Measure	Time frame	Description
Correlations between the CPGQ items, total, subscale scores and the SF-12 PCS, MCS scores	At recruitment (baseline)	—

Change in CPGQ total scale and subscale scores	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.
Factor analysis of the Greek version of the CPGQ	At recruitment (baseline)	—
Cronbach's alpha values for the total scale and each subscale of the Greek version of the CPGQ	At recruitment (baseline)	—

Secondary

Measure	Time frame
Time employed in filling out the Greek version of the CPGQ	At recruitment (baseline)
Percentage of patients who were able to complete the Greek version of the CPGQ by themselves	At recruitment (baseline)
