| Summary: | 碩士 === 高雄醫學大學 === 心理學研究所 === 100 === Objective: To assess predictive factors important to clients with Metabolic Syndrome regarding intention to eat a healthful diet and do exercise within the Theory of Planned Behavior.
Design: A survey based on the Health Belief Model and Theory of Planned Behavior in addition of ISSB and a Physician-Patient Relationship questionnaire was administered at two hospitals in southern Taiwan in 2010.07-2011.10.
Participants: 250 clients (mean age [SD] age 55.32 [10.71]) with Metabolic Syndrome.
Analysis: Descriptive statistics, t test, correlation analysis, regression analysis, and path analysis was used to assess how well the variables of Health Belief Model and the Theory of Planned Behavior predicted behavioral intention to eat a healthful diet and do exercise.
Results: Perceived susceptibility, perceived barriers, behavioral models, self-efficacy, internal locus of control, and social support variables accounted for 32% of the variance in behavioral intention to eat a healthful diet; perceived susceptibility, perceived barriers, self-efficacy, internal locus of control, and social support variables accounted for 46% of the variance in behavioral intention to do exercise. Social support had the greatest influence on behavioral intention to eat a healthful diet (β =.228, p < .01), and self-efficacy had the greatest influence on behavioral intention to do exercise (β =.340, p < .01). Perceived barriers, cognitive norms, behavioral models, external (powerful others) locus of control, social support, and physician-patient relationship variables accounted for 26% of the variance in behavior to eat a healthful diet; Perceived barriers, behavioral models, self-efficacy, and behavioral intention variables accounted for 58% of the variance in behavior to do exercise. Social support had the greatest influence on behavior to eat a healthful diet (β =.210, p < .01), and self-efficacy had the greatest influence on behavior to do exercise (β =.407, p < .01). By all accounts, perceived barriers and social support had the biggest impact on intention to health behaviors, and self-efficacy to health behaviors.
Conclusions and Implications: Medical professionals must provide strategies and supports for clients with Metabolic Syndrome to conquer the perceived barriers of preventive actions, and therefore improve clients’ self-efficacy to health behaviors.
