Validation of a queationnaire to detect kinesiophobia (fear of movement) in patients with coronary artery disease

• Purpose The aim of the study was twofold; firstly to examine the reliability and validity of the Tampa Scale for Kinesiophobia Heart (TSK-SV Heart), and secondly to investigate the occurrence of kinesiophobia among patients with coronary artery disease (CAD). Relevance Kinesiophobia, i.e. debilitating fear of movement, in relation to cardiac disease is a well-known clinical phenomenon. So far, however, there is not known which role kinesiophobia, plays for the level of physical activity in patients with CAD. Participants The study consisted of 331 patients (75 women), age 65±9.1 years, with CAD who attended the medical department at Sahlgrenska University Hospital between year 2007–2009. Exclusion criteria were death during the hospital period, serious diseases interfering participation in the study and inability to understand the Swedish language. Methods The patients were asked to fill in the TSK-SV Heart, which comprises of 17 items that assess the patient’s subjective rating of kinesiophobia. An operational definition of kinesiophobia was defined as TSK-SV Heart >37 points. The reliability test included stability over time, internal consistency and homogeneity. The test of validity comprised face validity, content validity and construct validity. Results In terms of reliability the TSK-SV Heart was found to be stable over time (Intraclass Correlation Coefficient 0.84) and internal consistency measured with Cronbach’s alpha was 0.84. The TSK-SV Heart was considered to have face, content and construct validity. Twenty percentage of the patients had kinesiophobia (TSK-SV Heart >37 points). Conclusion: TSK-SV Heart seems to be a reliable and valid and could be used to detect kinesiophobia in patients with CAD. Impact: One third of a sample of patients with CAD suffered from kinesiophobia, which might negatively impact the patients’ future level of physical activity.
