Research on the role of acceptance in adjustment to persisting pain has been facilitated by the development
of the Chronic Pain Acceptance Questionnaire (CPAQ). However, the CPAQ has not yet been
validated amongst Iranian patients with chronic pain. To examine the psychometric properties of the
Persian version of the CPAQ (P-CPAQ), 245 Persian-speaking chronic pain patients completed a battery
of questionnaires, including: the P-CPAQ, a Pain Self-Efficacy Questionnaire, a slightly modified Roland
and Morris Disability Questionnaire, the Catastrophizing Scale of the Coping Strategies Questionnaire,
the Depression and Anxiety Scales of the Depression Anxiety And Stress Scale-21 and the Pain-Related
Interference and Pain Intensity Scales of the Multidimensional Pain Inventory. Furthermore, to evaluate
the reliability of the P-CPAQ, the measure was completed by 24 chronic pain patients, on two occasions
that are 2weeks apart. The results of the principal component analysis and confirmatory factor analysis
yielded a two-factor solution. Furthermore, the reliability and construct validity of the P-CPAQ were
confirmed. In general, consistent with studies in other countries, the results of the present study indicate
that pain acceptance plays an important role in adjustment to chronic pain regardless of cultural and
language differences between countries.
