Relationship of self-effecacy to cholesterol lowering and dietary change in hyperlipidemia

Abstract

This study examined whether self-efficacy was associated with lipid lowering and dietary change among men undergoing dietary counseling to lower cholesterol levels. Twenty-five hyperlipidemic men (total cholesterol ≧220 mg/dL) participated in four weeks of dietary instruction. Plasma lipids were measured prior to treatment, at posttreatment, and at three- and twelvemonth follow-up. Dietary intake and self-efficacy as measured by the revised Eating Self-Efficacy Scale (ESES-R) were assessed at pretreatment, posttreatment, and three-month follow-up. Pre-treatment to posttreatment increases in self-efficacy in situations characterized by negative affect were related to extent of lipid lowering and dietary change. Although subjects showed significant reductions in cholesterol levels following treatment, by one year, lipid levels had returned to pretreatment values. Factors related to long-term maintenance of dietary change and lipid lowering among hyperlipidemics merit further research.
