Persons with metabolic syndrome are at high risk of cardiovascular disease, diabetes and non-communicable diseases. Perceived self-efficacy in health behavior modification is essential. This quasi-experimental study aimed to examine the effects of self-efficacy promotion on health behaviors, body weight, body mass index, and waist circumference among persons with metabolic syndrome. The participants were persons with metabolic syndrome who attended the Out Patient Department, Srisangwan Hospital, Meahongson province, from March to April 2015. Fifty-four of participants were purposively selected and randomly assigned to experimental and control groups with 27 participants in each group. Participants in the experimental group received self-efficacy enhancement from the researcher, while those in the control group received routine service care. Research instruments consisted of a demographic data recording form, a Health Behaviors of Metabolic Syndrome Persons questionnaire, a Perceived Self-efficacy of Metabolic Syndrome Persons questionnaire, a Metabolic Syndrome Persons Self-efficacy Enhancement Plan, and a Health Behaviors of Metabolic Syndrome Persons handbook. Data were analyzed by using descriptive statistics and the t-test for independent sample.

The results revealed that: 1. The health behaviors of persons with metabolic syndrome who received self-efficacy enhancement were significantly better than those who received routine service care (p< .001) 2. The body weight of persons with metabolic syndrome who received self-efficacy enhancement was significantly less than those who received routine service care (p< .001) 3.The body mass index of persons with metabolic syndrome who received self-efficacy enhancement was significantly less than those who received routine service care (p< .001) 4.The waist circumference of persons with metabolic syndrome who received self-efficacy enhancement was significantly less than those who received routine service care (p< .001).

               The results from this study demonstrated that self-efficacy enhancement among persons with metabolic syndrome yielded desired outcomes. Therefore, self-efficacy enhancement is suggested as one of the means to improve quality of care  among the population per se.
