Investigating the Related Factors and Outcome of Kinesiophobia and the Effects of Multidimensional Interventions in Cardiac Surgery Patients

Tampa Scale of Kinesiophobia for Heart (TSK Heart) was used for measuring kinesiophobia in this study. The TSK Heart developed by Bäck et al. (2012), assesses fear of movement in patients with coronary artery disease. It comprises four dimensions: exercise avoidance, fear of injury, dysfunctional self-perception, and perceived risk of heart problems, with 17 items. Each item is scored on a 4-point Likert scale (1 = strongly disagree to 4 = strongly agree), and items 4, 8, 12, and 16 are reverse scored. The total score ranges from 17 to 68, with higher scores indicating greater fear of movement. A TSK Heart score below 37 indicates a low fear of movement, while a score of 37 or higher indicates a high fear of movement. The scale's intra-class correlation coefficient is 0.83, and its internal consistency (Cronbach's alpha) is 0.78 (Bäck et al., 2012).

This study uses the short form of the Taiwan version of the IPAQ, developed in collaboration with Liu Ying-Mei and the World Health Organization. It consists of 7 items assessing physical activity over the past week across work, household chores, transportation, and leisure activities, including time and frequency of walking, moderate and vigorous activities, and time spent sitting. The total physical activity is calculated by multiplying each activity category by its corresponding Metabolic Equivalent (MET), execution time, and activity days. An IPAQ score below 600 indicates low physical activity, 600-3000 indicates moderate physical activity, and above 3000 indicates high physical activity. The scale's content validity is 0.994, and its intra-class correlation coefficient is 0.704 (Liou et al., 2008).

Professor Yao Kai-Ping developed this questionnaire after obtaining authorization; this questionnaire assesses the quality of life across four domains: physical health, psychological well-being, social relationships, and environment, with 28 items. Each item is scored on a 5-point scale. Scores for each domain are calculated by averaging the scores of the items within that domain and multiplying by 4. Items 3, 4, and 26 are reverse-scored by subtracting the original score from 6. Higher scores indicate a better quality of life. The internal consistency is 0.91, and the content validity of the domains ranges from 0.51 to 0.64 (Taiwan WHOQOL Group, 2000; Yao Kai-Ping, 2002).
