“…Prominent theories of health behavior change defend that first individuals need to become motivated to change their health behaviors and only after they need to acquire the right skills to implement the intended changes (Schwarzer, 2008;Weinstein & Sandman, 1992), but virtually no prior studies have directly tested this assumption. In the present study, two different interventions providing the same contents (i.e., motivational and self-regulatory), but in two different sequences (Sequence 1: first motivational followed by self-regulatory versus Sequence 2: self-regulatory followed by motivational) were compared in terms of their efficacy on the promotion of FV intake.…”

A B S T R A C T Background and Purpose:To evaluate the effectiveness of two subsequent intervention components (motivational and self-regulatory components), placed in different order, to promote fruit and vegetable (FV) intake. Methods: After baseline assessment, university students (N = 205, aged 18-26 years) were allocated to two groups. One group received a motivational intervention (outcome expectancies, risk perception, and task self-efficacy) followed by a self-regulatory intervention (planning and dietary selfefficacy) after 17 days. The second group received the same intervention conditions in the opposite order. Follow-up assessments were done after another 17 days. Results: Both intervention sequences yielded gains in terms of FV intake and self-efficacy. However, this gain was only due to the self-regulatory component whereas the motivational component did not contribute to the changes. Moreover, changes in intention and self-efficacy mediated between intervention sequence and follow-up behavior, suggesting that improving these proximal predictors of FV intake was responsible for the behavioral gains. Conclusions: Findings highlight the superiority of a self-regulatory intervention over a motivational intervention when it comes to dietary changes in this sample of young adults. Moreover, changes in dietary selfefficacy may drive nutritional changes.© 2014 Elsevier Ltd. All rights reserved. IntroductionUnderscoring the benefits of consuming a sufficient amount of fruit and vegetables (FV), a World Health Organization (WHO) review on the effectiveness of interventions and programs promoting FV intake showed that consumption of FV reduces cardiovascular diseases, cancers, diabetes, obesity and prevents several micronutrient deficiencies, especially in less developed countries (Pomerleau, Lock, Knai, & McKee, 2005). However, most people do not attain the recommendation of a minimum of 400 g of FV per day (i.e., approximately five portions). Moreover, this review highlights the need for data collection on FV intervention effectiveness in the majority of countries. India is a vast subcontinent covering 2.4% of the global landmass, it is inhabited by more than one-sixth of the world's population. Currently, the country is undergoing a rapid socio-economic, demographic, and health transition. For instance, over the last two decades, preventive nutrition has emerged as a public health concern; there have been increases in the prevalence of obesity, diabetes, and cardiovascular diseases, especially in urban areas (Ramachandran, 2006). Thus, evidence-based interventions are needed for the promotion of FV intake, as well as an understanding of the underlying working mechanisms of intervention effectiveness. In addition to basic nutritional knowledge, both motivation and self-regulation are required for people to change their habitual dietary patterns (Adriaanse, Vinkers, De Ridder, Hox, & De Wit, 2011;Verhoeven, Adriaanse, Evers, & De Ridder, 2012). Motivational and self-regulational mechanisms of health behavio...

“…Although incorporation of relevant theories into applications does not necessarily guarantee the success of applications in inducing changes of behaviour, there is a strong likelihood that such a system would likely be more capable in achieving this through design. For instance, in Mobile Snack, Khan et al [63] incorporated the Transportation Theories [112,13] and Precaution Adoption Process Model [114] by providing an immersive animation-based narrative that depicted the game characters' progressive life stages based on their eating behaviour. They also applied Social Cognitive Theory [115] by allowing users to view their eating behaviour history and compare themselves with other users.…”

Evidence has shown that the trend of increasing obesity rates has continued in the last decade. Mobile phone applications, benefiting from their ubiquity, have been increasingly used to address this issue. In order to increase the applications' acceptance and success, a design and development process that focuses on users, such as User-Centred Design, is necessary. This paper reviews reported studies that concern the design and development of mobile phone applications to prevent obesity, and analyses them from a User-Centred Design perspective. Based on the review results, strengths and weaknesses of the existing studies were identified. Identified strengths included: evidence of the inclusion of multidisciplinary skills and perspectives; user involvement in studies; and the adoption of iterative design practices. Weaknesses included the lack of specificity in the selection of end-users and inconsistent evaluation protocols. The review was concluded by outlining issues and research areas that need to be addressed in the future, including: greater understanding of the effectiveness of sharing data between peers; privacy; and guidelines for designing for behavioural change through mobile phone applications. Keywords: obesity, user-centred design, mobile phone, ubiquitousRecent evidence shows that the worldwide obesity rate is increasing and has more than doubled since 1980 [1]. The latest data from the Centres for Disease Control and Prevention (CDC) showed that more than one third of US adults were obese, with adults aged 60 and over more likely to be obese than younger adults [2]. Similar trends have been reported in Europe, where between 30% and 80% of adults are obese with higher prevalence of obesity among men than women [3]. Obesity and being overweight have considerable effects on morbidity and mortality through various diseases such as type-2 diabetes, cardiovascular diseases and metabolic syndrome [3]. Obesity yields neg...

“…However, evidence suggests that it is important to ensure that individuals are motivated before they are provided with volitional strategies and techniques (e.g. planning) to promote the translation of this motivation into health behaviour change (Schwarzer, 2008;Sheeran, Webb, & Gollwitzer, 2005;Weinstein & Sandman, 1992). With this in mind, the present intervention drew on the HAPA to identify the putative determinants of motivation (e.g.…”
