The purpose of this study was to assess the psychometric properties, appropriateness, and demographic response patterns of an exercise self‐efficacy scale for Korean adults with chronic diseases. After assessment of face validity by an expert Korean panel, 249 Korean adults with chronic diseases, ages 18–79 years, were recruited from hospitals or health centers in five Korean cities and surrounding rural areas to complete the questionnaire. In a factor analysis the original 18‐item exercise self‐efficacy scale converged to one factor without rotation and to three subfactors with rotation: situational/interpersonal factor, competing demands factor, and internal feelings factor. Descriptive analysis showed that Korean adults with chronic diseases perceived they had relatively low exercise self‐efficacy, with the situational/interpersonal factor as the lowest factor. Exercise self‐efficacy was significantly correlated with gender, education, regular exercise, and frequency of exercise. The exercise self‐efficacy scale was shown to be a useful measure of exercise beliefs of Korean adults with chronic diseases. © 2001 John Wiley & Sons, Inc. Res Nurs Health 24, 68–76, 2001
