The Chronic Pain Grade Questionnaire (CPGQ) is a seven item instrument designed to evaluate overall severity of chronic pain based on two dimensions, pain intensity and pain-related disability, in individuals who suffer from chronic pain that has lasted for at least six months. The notion of graded classification of chronic pain severity was derived from the dysfunctional chronic pain concept provided by Turk and Rudy (1988). The two disability items were adopted from the Multidimensional Pain inventory (Von Korff et al 1992).
