ObjectiveTo 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.DesignMethodological research (cross-sectional study).SubjectsA 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.MethodsThe 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.ResultsIn 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.ConclusionThese 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.
