Background Regarding 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.
Objectives The 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.
Methods 47 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.
Results There 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<0.01), and BAS (r=0.545, p<0.01).
Conclusions Test-retest reliability of the Turkish version of the PASS-20 was found to be good in our study and it was seen that this scale could be used in clinics for patients with rheumatic diseases. This study is considered as a preliminary report in terms of validation of the PASS-20 because of the lack of participated patients number. However, pre-results indicates that PASS-20 scale is usefull for rheumatic patients with pain in Turkey.
