Psychometric evaluation of the exercise self-efficacy scale among Korean adults with chronic diseases

The purpose of this study was to assess the psychometric properties, approp riateness, and demographic response patterns of an exercise self-efficacy s cale for Korean adults with chronic diseases. After assessment of face vali dity by an expert Korean panel, 249 Korean adults with chronic diseases, ag es 18-79 years, were recruited from hospitals or health centers in five Kor ean cities and surrounding rural areas to complete the questionnaire. in a factor analysis the original 18-item exercise self-efficacy scale conversed to one factor without rotation and to three subfactors with rotation: situ ational/interpersonal factor, competing demands factor, and internal feelin gs factor. Descriptive analysis showed that Korean adults with chronic dise ases perceived they had relatively low exercise self-efficacy, with the sit uational/interpersonal factor as the lowest factor. Exercise self-efficacy was significantly correlated with sender, education, regular exercise, and frequency of exercise. The exercise self-efficacy scale was shown to be a u seful measure of exercise beliefs of Korean adults with chronic diseases. ( C) 2001 John Wiley & Sons, Inc.
