Abstract
The purposes of this study were to develop a self-efficacy scale and an intervention program for prevention of hyperlipidemia in adults in their 30s and 40s. The development of the self-efficacy scale consisted of 2 stages. The 1st stage defined health behavior for prevention of hyperlipidemia based on interviews and the creation of an original scale. Then, seven experts examined the original scale. As a result, the self-efficacy scale was modified to 40 items. In the 2nd stage, we asked local government officials in their 30s and 40s to answer a questionnaire. The questionnaire included items about health behavior and the 40 self-efficacy items for prevention of hyperlipidemia. A total of 594 valid responses were analyzed. As a result of factor analysis, the self-efficacy scale for prevention of hyperlipidemia for adults in their 30s and 40s was finalized at 3 factors and 16-items. The three factors were "exercise and activity modification without excess," "basis of behavior modification" and "active modification of diet." The internal consistency of the self-efficacy scale indicated by Cronbach's standardized alpha was 0.855. Test-retest reliability was 0.809. The self-efficacy scale was significantly associated with health behavior, and reflected health behavior for hyperlipidemia prevention. In addition, the reliability of the self-efficacy scale was indicated. However limitations of this study were that selection bias and response bias occurred.
