Validity and Reliability of the Turkish Chronic Pain Acceptance Questionnaire

Background: Pain acceptance is the process of giving up the strugglewith pain and learning to live a worthwhile life despite it. In assessingpatients with chronic pain in Turkey, making a diagnosis and trackingthe effectiveness of treatment is done with scales that have beentranslated into Turkish. However, there is as yet no valid and reliablescale in Turkish to assess the acceptance of pain.Aims: To validate a Turkish version of the Chronic Pain AcceptanceQuestionnaire developed by McCracken and colleagues.Study Design: Methodological and cross sectional study.Methods: A simple randomized sampling method was used inselecting the study sample. The sample was composed of 201 patients,more than 10 times the number of items examined for validity andreliability in the study, which totaled 20. A patient identificationform, the Chronic Pain Acceptance Questionnaire, and the BriefPain Inventory were used to collect data. Data were collected byface-to-face interviews. In the validity testing, the content validityindex was used to evaluate linguistic equivalence, content validity,construct validity, and expert views. In reliability testing of the scale,Cronbach’s α coefficient was calculated, and item analysis and splittestreliability methods were used. Principal component analysis andvarimax rotation were used in factor analysis and to examine factorstructure for construct concept validity.Results: The item analysis established that the scale, all items, anditem-total correlations were satisfactory. The mean total score of thescale was 21.78. The internal consistency coefficient was 0.94, andthe correlation between the two halves of the scale was 0.89.Conclusion: The Chronic Pain Acceptance Questionnaire, which isintended to be used in Turkey upon confirmation of its validity andreliability, is an evaluation instrument with sufficient validity andreliability, and it can be reliably used to examine patients’ acceptanceof chronic pain.
