Abstract Background Relying solely on altruistic appeals may fail to fulfil the increasing demand for blood supplies. Current research has largely been attempted to determine and understand motives that serve as blood donation drivers. The Trans-Theoretical Model of behaviour change (TTM) can be used to conceptualise the process of intentional blood donation behaviour. Methods A cross sectional survey of Spanish adults was conducted. The final sample consisted of 504 individuals who were administered a self-report questionnaire including the measures of demographic characteristics, Stages of Change, Processes of Change, Self-efficacy and Decisional Balance. Data were analysed by frequency analysis, MANOVA/ANOVA and correlation analysis. Results Findings indicated that most of the behavioural and cognitive processes of change, self-efficacy and physical cons differentiated participants across the stages of change of blood donation. In contrast, eligibility cons and pros were less influential in stage transitions. Furthermore, significant correlations were observed between TTM constructs except for the physical cons and the processes of change. Conclusions The present study extensively supports and replicates the applicability of the TTM to blood donation behaviour change and offers important implications for the development of effective stage-matched interventions to increase blood donation.

An intervention to promote use of food thermometers when cooking small cuts of meat was conducted using the Transtheoretical Model. Objectives were to (i) increase use of food thermometers by home food preparers, (ii) improve consumers' attitudes regarding use of a food thermometer, and (iii) examine relationships between stages of change and decisional balance, self-efficacy, and processes of change. A randomly selected group of residents of Washington and Idaho (n = 2,500) were invited to participate in the research; 295 persons completed all phases of the multistep intervention. Following the intervention program, there was a significant increase in food thermometer use when cooking small cuts of meat (P < 0.01); those persons classified in action and maintenance stages increased from 9 to 34%. Ownership of thermometers also significantly increased (P < 0.05). The three constructs related to the Transtheoretical Model that were used in the study (decisional balance, self-efficacy, and processes of change) were very useful for examining differences among people at different stages of change because the responses for each set of questions differed positively and significantly (P < 0.01) as stages of change classifications advanced from precontemplation (no interest in thermometer use) to action and maintenance (individuals who use food thermometers). Additional educational campaigns designed to increase use of food thermometers are needed. Because most consumers are currently in the precontemplation stage, food thermometer campaigns will be most effective when they are focused on raising awareness of the food safety risks and the benefits of using food thermometers when cooking small cuts of meat.

A high proportion of individuals with disabilities remain physically inactive. Therefore, this study (web-based survey) investigated the relationships between the Transtheoretical Model (TTM) and physical activity among 224 adults with physical disabilities (M age = 45.4 years, SD = 10.78, females = 71%). Additionally, the most important TTM predictors of the stages of change and physical activity were examined. Standardized self-report scales of the TTM constructs and physical activity were completed. The study findings supported the theorized relationships between the TTM constructs and physical activity. The behavioral and cognitive processes of change distinguished the stages of change. These two constructs and self-efficacy mostly predicted physical activity (R2total = .18). The assessment methodology of the TTM constructs needs to be revisited.

Purpose Regular breakfast with a variety of nutrients can lead to improving educational performance, learning ability, reducing behavioral problems in elementary students. This study aims to use the Trans-Theoretical Model (TTM) to assess the mediating effect of self-efficacy in regular breakfast consumption among children of Ardabil elementary schools. Design/methodology/approach This cross-sectional study was performed between 300 students from elementary schools of different regions of Ardabil city by cluster sampling method. The instrument used in this study was the TTM standard questionnaire. Data was analyzed with Spearman correlation and regression using SPSS v18 software to identify the mediating effects of self-efficacy. Findings The mean age (SD) OF children was 11.2 (1.26) and 50% of them were female. Self-efficacy was the strongest predictor in stage promotion (ß = 0.44, P = 0.001), as well as had a mediating effect on the impact of other constructs of the model such as experiential processes (ß = 0.35, P = 0.04) and pros (ß = 0.44, P = 0.03) with stages of change. Pros were a significant predictor of self-efficacy in the first equation (ß = 0.17, P = 0.001) and Pros were a significant predictor of stages of change in the second equation when mediated by self-efficacy (ß = 0.11, P = 0.03). In the third equation, both the mediator, myself-efficacy and the predictor, Pros of breakfast consumption, were significantly associated with stages of change. The mediating effects of self-efficacy on the association between experiential processes and stages of change were also confirmed. The increased standardized beta coefficients of experiential processes between equations 3(ß = 0.35) and 2(ß = 0.29). Originality/value Due to the importance of eating a healthy breakfast regularly in children, this study aimed to use TTM to assess mediating effects of self-efficacy in regular breakfast consumption in Ardabil elementary students.

<em>Background</em>. The Trans-Theoretical model (TTM) and Theory of Planned Behaviour (TPB) may be promising models for understanding and predicting reduction in the consumption of fast food. The aim of this study was to examine the applicability of the Trans-Theoretical model (TTM) and the additional predictive role of the subjective norms and perceived behavioural control in predicting reduction consumption of fast food in obese Iranian adolescent girls. <br /><em>Materials and methods</em>. A cross sectional study design was conducted among twelve randomly selected schools in Sabzevar, Iran from 2015 to 2017. Four hundred eighty five randomly selected students consented to participate in the study. Hierarchical regression models used to predict the role of important variables that can influence the reduction in the consumption of fast food among students. using SPSS version 22. <br /><em>Results</em>. Variables Perceived behavioural control (r=0.58, P&lt;0.001), Subjective norms (r=0.51, P&lt;0.001), self-efficacy (r=0.49, P&lt;0.001), decisional balance (pros) (r=0.29, P&lt;0.001), decisional balance (cons) (r=0.25, P&lt;0.001), stage of change (r=0.38, P&lt;0.001), were significantly and positively correlated while experiential processes of change (r=0.08, P=0.135) and behavioural processes of change (r=0.09, P=0.145), were not significant.<br /><em>Conclusions</em>. The study demonstrated that the TTM (except the experiential and behavioural processes of change) focusing on the perceived behavioural control and subjective norms are useful models for reduction in the consumption of fast food.

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.
