Two research instruments were used for data collection. Attitude change, the dependent variable, was determined through the retrospective post- and then pretest questionnaire. A P value of less than .05 was applied to identify statistical significance. The best model developed from this study indicated that, for an effective nutritional attitudinal change, the messages should be composed of both emotion and logic in addition to credibility. This study reinforces not only the importance of message credibility and content but also the role that digital technology plays in nutrition intervention and counseling. © 2018 Wolters Kluwer Health, Inc.
