Network analysis of perception of exercise benefits/barriers and kinesiophobia among patients with cardiovascular diseases.

BACKGROUND: Perception of exercise benefits/barriers and kinesiophobia are important predictors of low exercise behaviors in patients with cardiovascular diseases (CVDs). Little is known about the complex intercorrelations between different components of perception of exercise benefits/barriers and kinesiophobia. OBJECTIVES: To identify the central components of kinesiophobia and to explore the interconnectedness between perception of exercise benefits/barriers and kinesiophobia. METHODS: A total of 258 patients with CVDs were recruited in this study. The Tampa Scale for Kinesiophobia Heart and the Exercise Benefits/Barriers Scale were used to assess kinesiophobia and perception of exercise benefits/barriers. R software was used to visualize the networks and analyze the centrality of the networks. The index "expected influence" and "bridge expected influence" were employed to identify the central components and the bridge components of the networks. RESULTS: In the item network of kinesiophobia, three items ("It is really not safe for a person in my condition to be physically active/exercise", "I cannot do the same things as others because there is a too big risk that I will get heart problems", and "If I tried to be physically active/exercise my heart problem would increase") had the highest expected influence. In the exercise benefits/barriers-kinesiophobia network, the dimension of physical exertion had the highest positive bridge expected influence, while psychological outlook had highest negative value. CONCLUSIONS: The three central components of kinesiophobia and the two bridge components (perception exercise barriers of physical exertion and perception exercise benefits of psychological outlook) should be targeted in specific intervention for relieving kinesiophobia and further promoting exercise behaviors.

Needs and Constraints for Cardiac Rehabilitation Among Patients with Coronary Heart Disease Within a Community-Based Setting: A Study Based on Focus Group Interviews.

Objective: This study aimed to explore the needs and constraints to cardiac rehabilitation (CR) among patients diagnosed with coronary heart disease (CHD) in a community-based setting, and thereby facilitating the implementation of effective CR programs for this population. Methods: Focus group interviews were used as the primary research methodology. A total of 11 community-dwelling individuals diagnosed with CHD were selected from a community hospital to participate in in-depth interviews, aiming to discern and analyze their requirements and constraints experienced concerning medical resources and healthcare agency. The textual data underwent examination using Colaizzi's method of descriptive data analysis. Results: Deficits existed in the perceptions of patients with CHD within a community-based setting about their condition and CR, and in the social support for this disease. Patients expressed expectations for professional guidance during CR, gained an understanding about the beneficial effects of emotional stability on cognitive function. Patients expressed their thoughts and feelings regarding the diversity of physical exercise options. Two main themes and seven sub-themes were identified: (a) "Insufficient CR resources for patients": Lack of awareness about CHD; inadequate knowledge about secondary prevention/CR; insufficient support from family and friends. (b) "Patient CR initiative": Patient self-adjustment; expectation of professional rehabilitation guidance; stable emotions improving cognition; diverse attitudes and awareness of exercise. Conclusion: For more effective CR, community-based medical teams should provide more comprehensive and individualized rehabilitation programs. They should focus on individual variations and preferences of patients, as well as enhance the autonomy of patients and improve their self-care ability through effective empowerment measures.
