This research sought to iteratively develop a theory-driven mobile app, Vegethon, to increase vegetable consumption.<\/p>\n<p style=\"text-align:justify\"><strong>METHODS<\/strong><br \/>\nDevelopment of Vegethon followed phases outlined by the IDEAS framework: 1) empathize with users (qualitative interviews, n&thinsp;=&thinsp;18); 2) specify target behavior; 3) ground in behavioral theory; 4) ideate implementation strategies; 5) prototype potential products; 6) gather user feedback (qualitative interviews, n&thinsp;=&thinsp;14; questionnaire, n&thinsp;=&thinsp;41); 7) build minimum viable product; and 8) pilot potential efficacy and usability (pilot RCT, n&thinsp;=&thinsp;17). Findings from each phase informed subsequent phases. The target population that informed intervention development was 18-50 years of age, had BMIs of 28-40 kg\/m(2), and lived in the geographical area surrounding Stanford University. A full description of the final version of Vegethon is included in the paper.<\/p>\n<p style=\"text-align:justify\"><strong>RESULTS<\/strong><br \/>\nQualitative findings that shaped initial intervention conception were: participants&#039; interests in accountability without judgment; their desire for simple and efficient dietary self-monitoring; and the importance of planning meals in advance. Qualitative findings identified during intervention refinement were the need for a focus on vegetable self-monitoring; inclusion of vegetable challenges; simplification of features; advice and inspiration for eating vegetables; reminder notifications; and peer comparison. Pilot RCT findings suggested the initial efficacy, acceptance, and feasibility of the intervention. The final version of Vegethon enabled easy self-monitoring of vegetable consumption and included a range of features designed to engage the user (e.g., surprise challenges; leaderboard; weekly reports). Vegethon was coded for its inclusion of 18 behavior change techniques (BCTs) (e.g., goal setting; feedback; social comparison; prompts\/cues; framing\/reframing; identity).<\/p>\n<p style=\"text-align:justify\"><strong>CONCLUSIONS<\/strong><br \/>\nVegethon is a theory-based, user-informed mobile intervention that was systematically developed using the IDEAS framework. Vegethon targets increased vegetable consumption among overweight adults and is currently being evaluated in a randomized controlled efficacy trial.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-17799","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Behavioural Science Group, Institute of Public Health, University of Cambridge, Cambridge, UK. sm885@cam.ac.uk","annee":"2016","mois":"8","numero":"13:","page":"90","auteurs":[{"ID":11393,"post_author":"0","post_date":"2018-12-03 18:34:46","post_date_gmt":"2018-12-03 17:34:46","post_content":"","post_title":"Stephen Sutton","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"stephen-sutton","to_ping":"","pinged":"","post_modified":"2018-12-03 18:34:46","post_modified_gmt":"2018-12-03 17:34:46","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/stephen-sutton\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":11394,"post_author":"0","post_date":"2018-12-03 18:34:46","post_date_gmt":"2018-12-03 17:34:46","post_content":"","post_title":"Christopher D Gardner","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"christopher-d-gardner","to_ping":"","pinged":"","post_modified":"2018-12-03 18:34:46","post_modified_gmt":"2018-12-03 17:34:46","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/christopher-d-gardner\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":17797,"post_author":"0","post_date":"2018-12-03 19:56:38","post_date_gmt":"2018-12-03 18:56:38","post_content":"","post_title":"Abby C King","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"abby-c-king","to_ping":"","pinged":"","post_modified":"2018-12-03 19:56:38","post_modified_gmt":"2018-12-03 18:56:38","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/abby-c-king\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":17798,"post_author":"0","post_date":"2018-12-03 19:56:38","post_date_gmt":"2018-12-03 18:56:38","post_content":"","post_title":"Sarah A Mummah","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"sarah-a-mummah","to_ping":"","pinged":"","post_modified":"2018-12-03 19:56:38","post_modified_gmt":"2018-12-03 18:56:38","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/sarah-a-mummah\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1610,"post_author":"0","post_date":"2018-12-03 16:00:56","post_date_gmt":"2018-12-03 15:00:56","post_content":"","post_title":"The international journal of behavioral nutrition and physical activity","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"the-international-journal-of-behavioral-nutrition-and-physical-activity","to_ping":"","pinged":"","post_modified":"2018-12-03 16:00:56","post_modified_gmt":"2018-12-03 15:00:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/the-international-journal-of-behavioral-nutrition-and-physical-activity\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
