| Abstract: | Research shows that people, who are at the contemplation stage of Transtheoretical Model of Behavior Change (TTM), experience multiple personal challenges, and therefore, need more guidance and knowledge in the process of adopting new behavior. In 2017, design researchers from the University of Twente (Ludden, Ozkaramanli, Karahanoglu 2017) proposed three possible strategies (guided flexibility, accounting for emotional gains and losses, dynamics of interventions) which could help people to overcome those challenges. This thesis further investigates the applicability of the aforementioned strategies that also work as the guidance of the intervention design proposed in this thesis. The goal of the thesis is to propose an interactive intervention concept to be used by people who experience challenges at decision making moments in the domain of healthy eating. In this thesis, complying with the knowledge gained from literature and multiple theories, a theoretical framework is presented in order to shed light on the process of self-initiated change of snacking at home. The framework includes constructs from Social Cognitive Theory (SCT) and delivers strategies in regard to a dynamic interplay of personal, behavioral, and environmental influences of behavior change. This framework combines three strategies proposed by the previously mentioned research. Following these, personal intentions, attitudes, feelings and common dilemma scenarios of unhealthy eating behavior are investigated. The results show that “snacking at home” is a commonly mentioned unhealthy eating behavior, especially among young adults, which is difficult to overcome even if desired. Based on the theoretical framework, accompanied by user research and design workshops, a set of smart intervention concepts are proposed. These suggest a deeper understanding of the combined effect of self-efficacy, self-regulation and facilitation strategies, in order to motivate people to gradually adopt healthy snacking habits. In the end, the thesis proposes one final interactive intervention concept which could help people to progress through the contemplation stage, and pursue a long-term goal of healthy snacking at home. |
