Real-time mobile-based ecological momentary assessments (mEMAs) may result in decreased measurement biases and minimize participant burden.<\/p>\n<p style=\"text-align:justify\"><strong>OBJECTIVE<\/strong><br \/>\nThe aim was to examine the validity of a mEMA methodology to assess dietary and physical activity levels compared to 24-hour dietary recalls and accelerometers.<\/p>\n<p style=\"text-align:justify\"><strong>METHODS<\/strong><br \/>\nThis study was a pilot test of the SPARC (Social impact of Physical Activity and nutRition in College) study, which aimed to determine the mechanism by which friendship networks impact weight-related behaviors among young people. An mEMA app, devilSPARC, was developed to assess weight-related behaviors in real time. A diverse sample of 109 freshmen and community mentors attending a large southwestern university downloaded the devilSPARC mEMA app onto their personal mobile phones. Participants were prompted randomly eight times per day over the course of 4 days to complete mEMAs. During the same 4-day period, participants completed up to three 24-hour dietary recalls and\/or 4 days of accelerometry. Self-reported mEMA responses were compared to 24-hour dietary recalls and accelerometry measures using comparison statistics, such as match rate, sensitivity and specificity, and mixed model odds ratios, adjusted for within-person correlation among repeated measurements.<\/p>\n<p style=\"text-align:justify\"><strong>RESULTS<\/strong><br \/>\nAt the day level, total dietary intake data reported through the mEMA app reflected eating choices also captured by the 24-hour recall. Entr&eacute;es had the lowest match rate, and fruits and vegetables had the highest match rate. Widening the window of aggregation of 24-hour dietary recall data on either side of the mEMA response resulted in increased specificity and decreased sensitivity. For physical activity behaviors, levels of activity reported through mEMA differed for sedentary versus non-sedentary activity at the day level as measured by accelerometers.<\/p>\n<p style=\"text-align:justify\"><strong>CONCLUSIONS<\/strong><br \/>\nThe devilSPARC mEMA app is valid for assessing eating behaviors and the presence of sedentary activity at the day level. This mEMA may be useful in studies examining real-time weight-related behaviors.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-18743","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Arizona State University, Phoenix, AZ, United States. meg.bruening@asu.edu","annee":"2016","mois":"7","numero":"18:7","page":"e209","auteurs":[{"ID":2323,"post_author":"0","post_date":"2018-12-03 16:54:29","post_date_gmt":"2018-12-03 15:54:29","post_content":"","post_title":"Meg Bruening","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"meg-bruening","to_ping":"","pinged":"","post_modified":"2018-12-03 16:54:29","post_modified_gmt":"2018-12-03 15:54:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/meg-bruening\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":5665,"post_author":"0","post_date":"2018-12-03 17:30:16","post_date_gmt":"2018-12-03 16:30:16","post_content":"","post_title":"Melissa N Laska","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"melissa-n-laska","to_ping":"","pinged":"","post_modified":"2018-12-03 17:30:16","post_modified_gmt":"2018-12-03 16:30:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/melissa-n-laska\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":15716,"post_author":"0","post_date":"2018-12-03 19:30:01","post_date_gmt":"2018-12-03 18:30:01","post_content":"","post_title":"Irene van Woerden","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"irene-van-woerden","to_ping":"","pinged":"","post_modified":"2018-12-03 19:30:01","post_modified_gmt":"2018-12-03 18:30:01","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/irene-van-woerden\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":8301,"post_author":"0","post_date":"2018-12-03 17:58:37","post_date_gmt":"2018-12-03 16:58:37","post_content":"","post_title":"Michael Todd","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"michael-todd","to_ping":"","pinged":"","post_modified":"2018-12-03 17:58:37","post_modified_gmt":"2018-12-03 16:58:37","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/michael-todd\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":11155,"post_author":"0","post_date":"2018-12-03 18:31:51","post_date_gmt":"2018-12-03 17:31:51","post_content":"","post_title":"Stephanie Brennhofer","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"stephanie-brennhofer","to_ping":"","pinged":"","post_modified":"2018-12-03 18:31:51","post_modified_gmt":"2018-12-03 17:31:51","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/stephanie-brennhofer\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":13690,"post_author":"0","post_date":"2018-12-03 19:01:04","post_date_gmt":"2018-12-03 18:01:04","post_content":"","post_title":"Genevieve Fridlund Dunton","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"genevieve-fridlund-dunton","to_ping":"","pinged":"","post_modified":"2018-12-03 19:01:04","post_modified_gmt":"2018-12-03 18:01:04","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/genevieve-fridlund-dunton\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1226,"post_author":"0","post_date":"2018-12-03 15:57:29","post_date_gmt":"2018-12-03 14:57:29","post_content":"","post_title":"Journal of medical Internet research","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-medical-internet-research","to_ping":"","pinged":"","post_modified":"2018-12-03 15:57:29","post_modified_gmt":"2018-12-03 14:57:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-medical-internet-research\/","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) -
