MethodsA total of 114 patients with chronic pain completed the questionnaire as well as other measures of pain, anxiety, depression, coping, and health-related quality of life. ResultsInternal consistency was satisfactory and the factorial analysis yielded a two-factor solution, confirming the original structure of the questionnaire. ConclusionThe psychometric properties of the Danish version of the 20-item CPAQ were satisfactory, showing that the Danish version of CPAQ is valid and reliable.
