Objective: To investigate the validity and reliability of the Tampa Scale for Kinesiophobia Heart (TSK-SV Heart), a brief questionnaire to detect kinesiophobia (fear of movement) in patients with coronary artery disease. Design: Methodological research (cross-sectional study). Subjects: A total of 332 patients, mean age 65 years (standard deviation 9. 1) diagnosed with coronary artery disease at a university hospital were included in the study. Methods: The psychometric properties of the TSK-SV Heart were tested. The tests of validity comprised face, content, and construct validity. The reliability tests included composite reliability, internal consistency and stability over time. Results: In terms of reliability, the TSK-SV Heart was found to be stable over time (intra-class correlation coefficient 0. 83) and internally consistent (Cronbach?s alpha 0. 78). Confirmatory factor analysis provided acceptable fit for a hypothesized 4-factor model with inclusion of a method factor. Conclusion: These results provide support for the reliability of the TSK-SV Heart. The questionnaire appears to be valid for use in patients with coronary artery disease. However, some items require further investigation due to low influence on some sub-dimensions of the test. The sub-dimensions of kinesiophobia require future research concerning their implications for the target group.Downloads
