Introduction

chronic pain grade questionnaire (CPG),a questionnaire for grading pain, was established several years ago before the publication of the World Health Organization's International Classification of Functioning Disability and Health (ICF). The purpose of the ICF was to give doctors a standard with which to work when comparing pain and health. The researchers in this study wanted to see if the two could be used together in assessing pain and disability. 

Purpose

The CPGS is a multidimensional measure that assesses 2 dimensions of overall chronic pain severity: pain intensity and pain-related disability. It is suitable for use in all chronic pain conditions, including chronic mus-culoskeletal (MSK) and low back pain (90)

Content 

Subscale scores for pain intensity and dis-ability are combined to calculate a chronic pain grade that enables classification of chronic pain patients into 5 hierarchical categories: grades 0 (no pain) to IV (high disability-severely limiting) (90).

Items

The CPGS is comprised of 7 items: 

1- How would you rate your pain on a 0-10 scale at the present time, this is right now, where 0 is 'no pain' and 10 is 'pain as bad as it could be'?
2- In the past 6 months, how intense was your worse pain rated on a 0-10 scale (rated as above)?
3- In the past 6 months, on average, how intense was your pain rated on a 0-10 scale (rated as above)? (That is your usual pain at times you were experiencing pain.)
4- About how many days in the last 6 months have you been kept from your usual activities (work, school, housework) because of this pain?
5- In the past 6 months, how much has this pain interfered with your daily activities on a 0-10 scale where 0 is 'no interference' and 10 is 'extreme change'?
6- In the past 6 months, how much has this pain changed your ability to take part in recreational, social, and family activities where 0 is 'no change' and 10 is 'extreme change'?
7- In the past 6 months, how has this pain changed your ability to work (including housework) where 0 is 'no change' and 10 is 'extreme change'?

Score

All items are scored on an 11-point Likert scale, with responses ranging from 0–10.

Recall Period

Pain in the past 3–6 months
