Purpose: Approximately one third of US adults are candidates for a cholesterol-lowering diet; however, less than 50% follow cholesterol-lowering dietary guidelines. Self-efficacy is one of many factors that may influence dietary adherence. Because self-efficacy is domain specific, it requires specificity in its measurement. We undertook a study to shorten the original 57-item Cholesterol-Lowering Diet Self-Efficacy Scale (CLDSES) and to evaluate the psychometric properties of the Short Form (CLDSES-SF). The purpose of this study was to examine: (1) internal consistency reliability; (2) dimensionality; (3) operating characteristics; and (4) criterion validity of the CLDSES-SF. Method: A survey design was used to administer three questionnaires: the CLDSES-SF, the Connor Diet Habit Survey (DHS), and a Three-Day Food Record, the latter two provided data on dietary adherence. Internal consistency reliability was assessed using coefficient alpha. Factor analytic procedures were used to examine the dimensionality of each subscale. For sensitivity and specificity we conducted a series of receiver operating characteristic (ROC) curve analyses; and for criterion validity evidence, we examined the relationship of the CLDSES-SF with the Connor DHS and Three-Day Food Record adherence scores.
