Abstract
\nPURPOSE: Test the applicability of the transtheoretical model (TTM) to adult fruit\/vegetable consumption. DESIGN: Cross-sectional random-digit dial survey. SETTING: Hawaii. SUBJECTS: 700 (62.6% female; age [mean +\/- SD], 47 +\/- 17.1 years; education [mean +\/- SD], 14.6 +\/- 2.8 years; 35.0% white, 31.1% Asian, 22.1% native Hawaiian\/Pacific Islander, 11.8% other). MEASURES: Stages, processes, self-efficacy, decisional balance, and self-reported fruit\/vegetable consumption. ANALYSIS: Confirmatory factor analysis tested the factor structure. Analyses of variance were used to explore stage differences in constructs. RESULTS: Stage distribution was precontemplation (33%), contemplation (4%), preparation (37%), action (3%), and maintenance (23%). A 10-factor process model with two higher-order correlated factors (experiential and behavioral) provided the best data fit (chi2 = 1446.12; df = 366; p < .0001; comparative fit index [CFI] = .89; standardized root mean square residual [SRMR] = .05). The self-efficacy structure fit the data well (chi 2 = 81.86; df = 9; p < .0001; CFI = .94; SRMR = .04), as did the decisional balance structure (chi2 = 37.42; df = 19; p = .007; CFI = .99; SRMR = .02). Processes, self-efficacy, decisional balance, and fruit\/vegetable consumption behavior differed significantly by stage, with medium effect sizes for most variables. CONCLUSION: The variables revealed adequate fit to the theorized measurement models. TTM predictions regarding stage differences in self-efficacy, pros and cons, and fruit\/vegetable consumption were confirmed; however, most experiential and behavioral processes increased in the early stages and then leveled off.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-41787","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Human Nutrition, University of Otago, Dunedin, New Zealand.","annee":"2010","mois":"5","numero":"24:5","page":"324-33","auteurs":[{"ID":34964,"post_author":"0","post_date":"2018-12-04 00:37:15","post_date_gmt":"2018-12-03 23:37:15","post_content":"","post_title":"Caroline C Horwath","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"caroline-c-horwath","to_ping":"","pinged":"","post_modified":"2018-12-04 00:37:15","post_modified_gmt":"2018-12-03 23:37:15","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/caroline-c-horwath\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":22460,"post_author":"0","post_date":"2018-12-03 21:04:53","post_date_gmt":"2018-12-03 20:04:53","post_content":"","post_title":"Claudio R Nigg","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"claudio-r-nigg","to_ping":"","pinged":"","post_modified":"2018-12-03 21:04:53","post_modified_gmt":"2018-12-03 20:04:53","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/claudio-r-nigg\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":34965,"post_author":"0","post_date":"2018-12-04 00:37:16","post_date_gmt":"2018-12-03 23:37:16","post_content":"","post_title":"Motl","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"motl","to_ping":"","pinged":"","post_modified":"2018-12-04 00:37:16","post_modified_gmt":"2018-12-03 23:37:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/motl\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1422,"post_author":"0","post_date":"2018-12-03 15:59:13","post_date_gmt":"2018-12-03 14:59:13","post_content":"","post_title":"Am J Health Promot.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"am-j-health-promot","to_ping":"","pinged":"","post_modified":"2018-12-03 15:59:13","post_modified_gmt":"2018-12-03 14:59:13","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/am-j-health-promot\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nInvestigating fruit and vegetable consumption using the transtheoretical model. -
