by (Christopher Mark) Reinold, Christopher M.

Abstract (Summary)
This study developed and validated the Youth-Directed Obesity Counseling Selfefficacy (Y-DOCS) Scale to evaluate the self-efficacy of registered dietitians (RDs) working with childhood overweight. The specific purpose of this study was to create an evaluation instrument that can measure the effectiveness of continuing education (CE) that provides behavioral counseling training. Two research questions guided this investigation into measuring the self-efficacy of RD’s: (a) Is the Y-DOCS scale for dietitians a reliable instrument for assessing selfefficacy among dietitians who receive training? (b) Is the Y-DOCS scale for dietitians a valid instrument for assessing self-efficacy among dietitians who receive training? The population for the study consisted of a convenience sample of 132 RDs who volunteered to take part in the survey. Analysis revealed the Y-DOCS Scale to be a reliable and valid scale. Reliability was measured by paired sample t-tests on individual items and the entire scale, and by Cronbach’s alpha. There was no significant difference in the total item scale and the pretest-posttest correlation of the scale was .939. Cronbach’s alpha was .963 (p < 0.01). Validity was determined by expert panel review, exploratory factor analysis (EFA), and iii
