Assessing kinesiophobia related to heart problems is important in terms of cardiac rehabilitation. The Tampa Scale of Kinesiophobia Swedish Version for the Heart (TSK-SV Heart) is reliable and has been validated for cardiac diseases in the Swedish population. The aim of this study was to investigate the reliability, parallel-form validity, and exploratory factor analysis of the TSK for the Heart Turkish Version (TSK Heart Turkish Version) for evaluating kinesiophobia in patients with heart failure and pulmonary arterial hypertension.Methods: This cross-sectional study involved translation, back translation, and cross-cultural adaptation (localization). Forty-three pulmonary arterial hypertension and 32 heart failure patients were evaluated using the TSK Heart Turkish Version. The 17-item scale, originally composed for the Swedish population, has four factors: perceived danger for heart problem, avoidance of exercise, fear of injury, and dysfunctional self. Cronbach’s alpha (internal ­consistency) and exploratory factor analysis were used to assess the questionnaire’s reliability. Results of the patients in the 6-minute walk test, International Physical Activity Questionnaire, and Nottingham Health Profile were analyzed by Pearson’s correlation analysis with the TSK Heart Turkish Version to indicate the convergent validity.Results: Cronbach’s alpha for the TSK Heart Turkish Version was 0.75, indicating acceptable internal consistency. Although exploratory factor analysis showed a different subgroup ­distribution than the original questionnaire, the model was acceptable for the four-factor model hypothesis. Therefore, the questionnaire was rated as reliable.Conclusion: These results supported the reliability of the TSK Heart Turkish Version. Since the acceptable four-factor model fits the subgroups and measures of reliability are sufficiently high, the questionnaire seems reliable for pulmonary arterial hypertension and heart failure patients.
