PROCESSES OF CHANGE ASSOCIATED WITH THE FRUIT AND VEGETABLE CONSUMPTION ACROSS STAGES OF CHANGE IN WOMEN- APPLICATION OF TRANSTHEORETICAL MODEL

Purpose. To examine the application of the transtheoretical model (TTM) to fruit and vegetable consumption among economically disadvantaged African-American adolescents. Methods. Scales for measuring decisional balance, situational self-efficacy, and processes of change for fruit and vegetable consumption were developed and pretested with 57 economically disadvantaged African-American adolescents. The scales and measures for assessing stages of change, demographic variables, and fruit and vegetable consumption were administered to a separate sample of 262 participants. t-tests for independent samples and analysis of variance were used to examine differences in TTM variables and fruit and vegetable consumption across stages of change. Results. Two-factor solutions for decisional balance and processes of change and a three-factor solution for situational self-efficacy provided the best fit to the data. Alpha coefficients of reliability for the scales ranged from .77 (experiential change processes) to .91 (pros). Participants in action-maintenance stages evidenced higher pros, self-efficacy, and fruit and vegetable consumption and significantly lower cons than did participants in precontemplation and contemplation-preparation stages. Also, participants in action-maintenance stages used processes of change more frequently than did those in precontemplation-contemplation-preparation stages. The use of experiential and behavioral processes within these stages did not differ significantly, as posited. Discussion. Observed differences in TTM variables and fruit and vegetable consumption by stage of change in this sample of economically disadvantaged African-American adolescents were consistent with theory and previous applications of the model to fruit and vegetable consumption in adults. With replication studies, the TTM may be appropriate for designing interventions to increase fruit and vegetable consumption among this population.

The Mean

Introduction: The World Health Organization recommended consuming at least 5 servings of fruits and vegetables (FV) per day in order to reduce the risk of non-communicable diseases (NCDs). The purpose of this study is to determine the influential factors related to intake of FV among adults in Kermanshah city based on Transtheoritical Model.Material and Methods: This is a cross-sectional study which is conducted in Kermanshah city. Participants (n=1230) are selected by multi stage sampling; 30-50 year olds people covered by health centers. In order to collect data, we used a TTM-based questionnaire. The results are analyzed using SPSS-16 and Lisrel 8, with P< 0.05 as statistically significant level.Results: The mean age of the participants is 37.75 and 65% of them are women .The mean score of knowledge is 2.4; that is, 80% of men and 78% of women in this study are in poor knowledge about FV consumption. In case of fruit and vegetable consumption behavior, 50% and 61% of participants are in pre-contemplation/contemplation stage, respectively. The average number of fruit servings is 1.42 and the average number of vegetable servings is 0.99 per day. Also, ANOVA test results showed a significant correlation between constructs of TTM and stages of change so that individuals' progress through stages of change from pre-contemplation to maintenance added on the scores of self-efficiency, processes of change, and decisional balance.Conclusion: This study indicated that, TTM constructs such as self-efficacy, processes of change, and decisional balance are good predictors for FV consumption.

The Impact

AbstractObjective:The present study aimed to evaluate the impact of a Transtheoretical Model-based programme titled ‘Fruit & Vegetable-Friendly’ on the fruit and vegetable (F&V) consumption of adolescents.Design:A quasi-experimental study. The ‘Fruit & Vegetable-Friendly’, a multicomponent intervention based on the Transtheoretical Model, was completed in eight weeks. The data were collected one week before the intervention, one week after the completion of the intervention and six months after the post-test with an F&V intake questionnaire and the stages of change, processes of change (α = 0·91), situational self-efficacy (α = 0·91) and decisional balance (α = 0·90 for pros, α = 0·87 for cons) scales. Data were analysed with the Friedman, Wilcoxon and marginal homogeneity tests.Setting:A public secondary school in Istanbul, Turkey.Participants:Seven hundred and two adolescents.Results:The mean (sd) F&V intake of adolescents in the passive stages rose from the daily average at the time of the pre-test of 3·40 (1·79) portions to 5·45 (2·54) portions on the post-test and to 5·75 (2·70) portions on the follow-up test (P < 0·01). While the students in the passive stages represented 41·6 % of the participants prior to the programme, this rate fell to 23·7 % at the post-test and to 22·7 % at the follow-up. Students in the active stages first represented 58·5 % of the participants; this rate rose to 76·4 % at the post-test and to 77·2 % at the follow-up test.Conclusions:The programme was effective in increasing the amount of F&V the adolescents consumed on a daily basis.

Behavior Change Theories

Abstract Background Literature has shown a tendency of inadequate dietary intake among youth, consequently, nutritional interventions are required. The transtheoretical model (TTM) classifies individuals based on their readiness to change. This model is widely used for health education interventions with proven efficacy. Purpose This review aimed to weigh the strength of evidence about the TTM usage in nutritional interventions for adolescents and its effectiveness regarding dietary intake. Methods This study followed the PRISMA guidelines. Eligible studies were input into Mendeley software. The Adolec, Google Scholar, LILACS, PsycINFO, PubMed, Science Direct and Web of Science databases were searched. Only full original articles written in English, Spanish or Portuguese on randomized controlled trials and quasi-experimental designs that applied the TTM in the design of nutritional interventions targeting adolescents were included, with no restrictions on publication date. The quality and risk of bias was evaluated with the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Results The initial search yielded 3779 results. Three studies were rated as strong, six as moderate and five as weak. The final sample of 14 articles included adolescents that were mostly recruited from schools, with interventions ranging from one month to three years. The TTM was used alone or combined with other behavior-change theories and most of the interventions involved digital technology. The nutritional topics covered included fruit and vegetable consumption, low-fat diet, and cooking skills. Four studies presented improvement in fruit and vegetable consumption and four progressed through stages of change. Participants from two interventions reduced fat intake. At the end of one intervention, all the participants were in action and maintenance stages. Conclusion The TTM seems to be a successful strategy for nutritional intervention aiming at improving dietary intake in adolescents. Its application in different contexts shows that the TTM is flexible and possible to be implemented in many settings. The use of the model is shown to be restricted to the stage of change’ construct. Further studies should use all constructs of the TTM in the design and compare the TTM with other behavior-change theories to better understand its effectiveness.
