AB1240-HPR Turkish Version of the Short Version of the Pain Anxiety Symptom Scale (PASS-20) and its Test-Retest Reliability and Validity: Preliminary Report

BackgroundRegarding to determine pain-related anxiety of patients in clinical trials, there are sufficient number of tools in the literature (1). On the other hand there is a lack of internationally accepted measures which adapted in Turkish population to assess pain-related anxiety.ObjectivesThe aim of this study was to translate the short version of the Pain Anxiety Symptom Scale (PASS-20) into Turkish, assess its test-retest reliability and validate the use of PASS-20 among patients.Methods47 patients with different rheumatic diseases (ankylosing spondylitis, rheumatoid arthritis…) aged between 21-71 years (mean 47.91±48.00 years) participated in this study. Translation/re trans-lation of the English version of the PASS-20 was done blindly and independently by four different individuals and adapted by a team. After the translation, 34 patients was performed Turkish PASS-20 with an interval of a week for the test/retest reliability. And also, all patients were asked to fill Tampa Kinesiophobia Scale (TKS) (2)and Beck Anxiety Scale (BAS) (3)for validation.ResultsThere was no difference between test and retest results (p>0.05). The test-retest reliability was found to be 0.864 (95% CI=0.706-0.937). Cronbach's alpha was 0.864. Construct validity, tested by determining the correlation between the Turkish PASS-20 and the Turkish adaptation of the TKS (r=0.554, p
