Objective: University of Washington Concerns About Pain Scale is an Item Response Theory-based scale to measure pain catastrophizing. The aim of this study was to develop the Turkish version of the 6-item University of Washington Concerns About Pain Scale-Turkish Version by adapting it linguistically and to examine the construct validity and reliability of the current version.
Methods: The methodology of this study was based on the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) guideline. Participants with chronic low back pain were administered University of Washington Concerns About Pain Scale-Turkish Version, the Turkish version of the Pain Catastrophizing Scale, and the Turkish version of the Fear-Avoidance Beliefs Questionnaire. Cronbach’s alpha coefficient and item analysis were used to assess internal consistency of University of Washington Concerns About Pain Scale-Turkish Version. The intra-class correlation coefficient was used to determine test–retest reliability of University of Washington Concerns About Pain Scale-Turkish Version. The confirmatory factor analysis and the Rasch analysis of University of Washington Concerns About Pain Scale-Turkish Version were also undertaken.
Results: The study was completed with 100 participants with chronic low back pain with a mean age 43.59 ± 14.83 years. University of Washington Concerns About Pain Scale-Turkish Version was found to have good internal consistency (Cronbach’s alpha=0.85) and excellent test–retest reliability [intra-class correlation coefficient(2.1): 0.97; P < .01]. University of Washington Concerns About Pain Scale-Turkish Version had a strong positive correlation with Turkish version of the Pain Catastrophizing Scale (r = 0.73, P < .01), a moderate positive correlation with Turkish version of the Fear-Avoidance Beliefs Questionnaire-physical activity (r = 0.46, P < .01), and a weak positive correlation with Turkish version of the Fear-Avoidance Beliefs Questionnaire-work (r = 0.37, P < .01).
Conclusion: University of Washington Concerns About Pain Scale-Turkish Version was shown to be a short, effective, valid, and reliable measurement method that can be used in both clinical and research settings to assess pain catastrophizing in Turkish individuals with chronic low back pain.
