An Investigation of the Validity and Reliability of Turkish Tampa Kinesiophobia Scale-Short Form in Individuals with Low Back Pain

Abstract

The aim of this study was to investigate the validity and reliability of the Turkish Tampa Kinesiophobia Scale-Short Form in individuals with low back pain. A total of 111 volunteer patients aged between 30 and 65 years (mean 48±12 years) and diagnosed with mechanical low back pain were included in the study. Explanatory factor analysis (EFA) and confirmatory factor analysis (CFA) were applied to the data to test the construct validity. Item-total correlations were calculated to test item discrimination and Cronbach-α values were calculated to test reliability. To determine the criterion validity, the Turkish versions of the Visual Analog Scale (VAS), the SF-36, the Fear-Avoiding Beliefs Questionnaire (FABQ), and the Roland-Morris Disability Questionnaire (RMDQ) as well as the TSK-11, which was translated into Turkish, were administered. There was no difference between the TSK-11 test and retest measurement results (P>0.05). Cronbach α levels for test and retest were calculated as 0.74 and 0.81. The variance of the first factor in the factor analysis was 35.372%, indicating that the Turkish version of the TSK-11 consisted of one dimension. As a result of DFA, the TSK-11 fit index criteria in other fit indices. In the test-retest analyses of the Turkish version of TSK-11, intraclass correlation coefficient (ICC) values ranged from 0.403 to 0.479, while TSK-11 Cronbach's alpha values were 0.727-0.748. There was a positive relationship between TSK-11 and FABQ, RMDQ, and VAS (r=436**, 589**, 589**, respectively), and a moderate negative relationship between TSK-11 and SF-36. In our study, the Turkish version of the TSK-11 was found to be valid and reliable. The TSK-11 can be used in clinical practice and research to evaluate fear of movement in individuals with low back pain in Turkish society.
