The study investigated the level, perception, and factors of perceived self-efficacy, outcome expectation, and self-care behavior in 3 categories (nutrition, physical exercise, and stress management) of hypertension patients. Sixty-two subjects with blood pressure controlled <160/100 mmHg receiving normal treatment and program were randomly selected from two settings.  Questionnaires with descriptive statistics, t-test and stepwise multiple regression were used to predict perceived self-efficacy and outcome expectations influencing self-care behavior.

          Most respondents perceived self-efficacy, outcome expectations, and self-care behavior in 3 categories (intermediate to the highest level).  The independent sample t-test demonstrated that self-efficacy in physical exercise of the sample at Langkao Hospital is significantly higher than that of Saonoi. The outcome expectation in nutrition aspects of the sample of Saonoi Hospital is significantly higher than that of Langkao. Perceived self-efficacy and outcome expectations in these 3 categories can significantly predict self-care behavior alone at the 95% (p < 0.05) level. The best factor significantly predicting self-care behavior (61.90%) is perceived self-efficacy in stress management (p < 0.05). These findings show that both hospitals should routinely offer health-related activities in the 3 categories. Information should be demonstrated with hands-on practice whenever possible. These findings reflect the initiative of Thai Public Health strategies and policies for non-communicable diseases (NCD).
