Participants (N = 557) completed pre-test measures of planning, motivation and behaviour with respect to increasing their fruit and vegetable intake before being randomised to a 3 (intervention format: control vs. &lsquo;if-then&rsquo; vs. &lsquo;global&rsquo; implementation intentions) x 2 (pre-intervention instruction vs. no pre-intervention instruction) between-participants design. Results revealed a significant intervention format by time interaction, such that intake significantly increased by 0.50 portions in the if-then format condition compared with 0.31 in the global format and 0.01 in the control condition. These results suggest that &lsquo;if-then&rsquo; manipulations are superior in promoting behaviour change in an applied setting. The use of pre-intervention instructions had no additional effect on behaviour, providing evidence for the efficacy of implementation intentions even when experimenter demand is reduced. Evidence is also presented to suggest that reported increases in intake are not related to demand characteristics.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-39200","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Psychology, University of Sheffield, Sheffield, S10 2TP, UK.\r\n\r\n","annee":"2009","mois":"3","numero":"24:3","page":"317-332","auteurs":[{"ID":30684,"post_author":"0","post_date":"2018-12-03 23:35:07","post_date_gmt":"2018-12-03 22:35:07","post_content":"","post_title":"Paul Norman","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"paul-norman","to_ping":"","pinged":"","post_modified":"2018-12-03 23:35:07","post_modified_gmt":"2018-12-03 22:35:07","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/paul-norman\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":29919,"post_author":"0","post_date":"2018-12-03 23:25:26","post_date_gmt":"2018-12-03 22:25:26","post_content":"","post_title":"K J Chapman","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"k-j-chapman","to_ping":"","pinged":"","post_modified":"2018-12-03 23:25:26","post_modified_gmt":"2018-12-03 22:25:26","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/k-j-chapman\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":27809,"post_author":"0","post_date":"2018-12-03 22:58:12","post_date_gmt":"2018-12-03 21:58:12","post_content":"","post_title":"Christopher J Armitage","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"christopher-j-armitage","to_ping":"","pinged":"","post_modified":"2018-12-03 22:58:12","post_modified_gmt":"2018-12-03 21:58:12","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/christopher-j-armitage\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":37111,"post_author":"0","post_date":"2018-12-04 01:11:37","post_date_gmt":"2018-12-04 00:11:37","post_content":"","post_title":"PSYCHOL HEALTH.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"psychol-health-2","to_ping":"","pinged":"","post_modified":"2018-12-04 01:11:37","post_modified_gmt":"2018-12-04 00:11:37","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/psychol-health-2\/","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) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Comparing implementation intention interventions in relation to young adults&#039;
