摘要:
Self-efficacy has been documented as a strong predictor of health behaviors. Unfortunately, availability of reliable and valid measures of self-efficacy for a range of health behaviors is still limited. This study validated two measures of cardiac risk factor self-efficacy; the Cardiac Diet Self-Efficacy Instrument (CDSEI) and the Cardiac Exercise Self-Efficacy Instrument (CESEI). A sample of 370 cardiac rehabilitation participants provided data for principal factor analyses showing the unidimensionality of each instrument. Known groups construct validity was supported by a comparison of CDSEI and CESEI scores for cardiac rehabilitation participants and marathon runners. The value of CDSEI and CESEI scores in predicting subsequent exercise and diet performance was demonstrated with a third group of cardiac rehabilitation participants. Stability and internal consistency estimates in the .80s and .90s, respectively, support the scales' reliabilities.
