Abstract Background Literature has shown a tendency of inadequate eating habits 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 and it has been associated with positive results. Purpose This review aimed to describe how the TTM has been applied to nutritional interventions for adolescents. Methods 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 to nutritional interventions targeting adolescents were included, with no restrictions on publication date. Results The initial search yielded 3779 results, of which 13 were included. Two more articles were added after a search update, totaling 15 articles. The included adolescents were mostly recruited from schools, and the duration of the studies ranged from one month to three years. The TTM was used alone or combined with other behavior-change theories. Nine interventions had positive results. The participants in six studies progressed through stages of change or improved decisional balance. Conclusion There are some limitations related to the studies included in this review, such as the differences in design and intervention exposure time, as well as using the TTM in association with other behavior-change theories. Nevertheless, the TTM seems to be a successful strategy for nutritional intervention in adolescents. Further studies comparing the TTM with other behavior-change theories should be conducted to better understand its effectiveness.

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.

At Risk Populations

The transtheoretical model posits that health behavior change involves progress through six stages of change: precontemplation, contemplation, preparation, action, maintenance, and termination. Ten processes of change have been identified for producing progress along with decisional balance, self-efficacy, and temptations. Basic research has generated a rule of thumb for at-risk populations: 40% in precontemplation, 40% in contemplation, and 20% in preparation. Across 12 health behaviors, consistent patterns have been found between the pros and cons of changing and the stages of change. Applied research has demonstrated dramatic improvements in recruitment, retention, and progress using stage-matched interventions and proactive recruitment procedures. The most promising outcomes to date have been found with computer-based individualized and interactive interventions. The most promising enhancement to the computer-based programs are personalized counselors. One of the most striking results to date for stage-matched programs is the similarity between participants reactively recruited who reached us for help and those proactively recruited who we reached out to help. If results with stage-matched interventions continue to be replicated, health promotion programs will be able to produce unprecedented impacts on entire at-risk populations.

Theoretical Approaches

The Transtheoretical Model (TTM) is an integrative health behavior change theory that describes the process of how people change their behavior. The central organizing construct in the theory is stages of change, which are five distinct stages of readiness to change behavior, ranging from not ready to change (precontemplation), thinking about change (contemplation), preparing to change (preparation), changing (action), and maintaining the change (maintenance). Movement through the stages may be nonlinear, and cycling and recycling through the stages is viewed as a natural part of the change process. Other model constructs explain what drives individuals forward through the stages of change. Decisional balance involves a weighing of pros and cons of changing behavior, while self-efficacy involves situation-specific confidence that one can change. Increases in pros, deceases in cons, and increases in self-efficacy propel people forward through the stages of change. The processes of change are experiential and behavioral strategies that people use to change their behavior. In early stages of change, people use experiential strategies while they use behaviorally oriented strategies in later stages of change. The TTM holds significant implications for message design. Most notably, messages should be targeted and tailored to stages of change, and where possible, to other model variables as well. Studies indicate that the TTM has been successfully applied to health communication campaigns, and to a larger extent, to computer-tailored interventions to change health behavior. Meta-analyses indicate that scores of computer-tailored interventions have been efficacious, including many based upon the TTM and stages of change. New applications of the model include a focus on novel health behaviors, multiple behavior change, and advancing an understanding of message design in the context of the TTM in combination with other theoretical approaches.

This article profiles the travel behavior of sport fans against the transtheoretical model of change (TTM) and its application to sport events. Using the four constructs of the TTM, we distributed a self-reporting survey to sport fans prior to home fixtures. There is some synergy with the theorized stages of change and processes of change in this context. Notwithstanding, the results showed a high level of commitment to others in the early stages of change—a movement away from the prescribed theory. Results from decisional balance and self-efficacy items reaffirmed the congruence with theory and the application of the TTM to sport fans and their travel behavior. This study assessed the application of a stage-based model of change within a sport event context; it provides an exploration of the antecedents of behavior change indicators relevant to sport fans, thus enabling policy makers to make informed decisions about future travel behavior change.

AbstractThis review provides a rigorous investigation of the question of whether the transtheoretical model (TTM) (or stages of change model) is applicable to eating behaviour change. The TTM is currently the most popular of a number of stage theories being used to examine health behaviour change. Stage theories specify an ordered set of ‘stages of readiness to change’ into which people can be classified and identify the factors that can facilitate movement from one stage to the next. If eating behaviour change follows a stage process, then nutritionists could identify the predominant stage or stages in a population and focus resources on those issues most likely to move people to the next stage (e.g. from no intention of changing, to thinking about changing). In addressing this question, the review draws on the defining characteristics of stage theories as clarified by Weinstein et al. (1998), provides an in-depth coverage of methodological considerations, and a detailed summary table of dietary studies applying the TTM. Specific recommendations are made for improving the accuracy of dietary stage classifications. Among the key conclusions are: (1) dietary studies using the TTM have been hampered by a focus on nutritional outcomes such as dietary fat reduction, rather than clearly understood food behaviours (e.g. five servings of fruit and vegetables per day); (2) accurate stage classification systems are possible for food-based goals, but major misclassification problems occur with nutrient-based goals; (3) observation of an association between stage and dietary intake is not sufficient to demonstrate the validity of the model for dietary behaviour; (4) there is a need for valid questionnaires to measure all aspects of the TTM, and more research on the whole model, particularly the ‘processes of change’, rather than on single constructs such as ‘stage’ (5) cross-sectional studies generally support the predicted patterns of between-stage differences in decisional balance, self-efficacy, and processes of change; (6) studies which test the key hypothesis that different factors are important in distinguishing different stages are rare, as are prospective studies and stage-matched interventions. Only such studies can conclusively determine whether the TTM is applicable to eating behaviour. Since the ultimate test of the TTM will be the effectiveness of stage-matched dietary interventions, the review ends by exploring the requirements for such studies.

Partner Violent Men

The Transtheoretical Model (TTM) of behavior change predicts that patients go through different stages of change prior to changing their problematic behavior. This study aims to evaluate the utility and validity of this model in a sample of 549 court-ordered partner violent men. Three types of perpetrators with respect to their readiness to change were revealed. Those in more advantage stage of change use more processes to change their problem and present with higher levels of intimate partner violence (IPV). Low readiness to change levels and treatment drop-out predict short-term criminal justice recidivism, while treatment drop-out predicts medium and long-term recidivism. Results highlight the applicability of the TTM in IPV and its usefulness in designing behavioral interventions with this population.
