Digital Nudging

Digitale Nudges stellen Elemente von User Interfaces dar, die Nutzerverhalten sanft in eine bestimmte Richtung lenken sollen. In unserer Forschung untersuchen wir, wie sich die Gestaltung von User Interfaces auf das Entscheidungs- und Nutzungsverhalten von Nutzer*innen auswirkt. Dabei greifen wir auf Erkenntnisse der Psychologie und Verhaltensökonomie zurück. Im Rahmen von angewandten Forschungsprojekten unterstützen wir Unternehmen bei der Entwicklung und Evaluation digitaler Nudges.

Wearables provide great opportunities for improving personal health, but research challenges their capacity to evoke behavioral change effectively. Realizing the full potential of wearables requires a better understanding of users’ behavior change processes. Based on self-efficacy theory, we investigate how wearables influence users’ perceptions of their self-efficacy and subsequent health behavior. Using narrative interviews with twenty-five long-term wearable users, we show that wearables can have both positive and negative effects on users’ perceptions of their self-efficacy and that these perceptions are subject to internal and external contexts, which can positively or negatively affect users’ compliance. We also find that the internal context may have a compounding or neutralizing effect on self-efficacy, despite an adverse external context. Our study shows the contextual and transient nature of self-efficacy, thus contributing to self-efficacy theory and research on wearables and offering practical design implications.

Business ecosystems are dynamic structures of various actors who co-create value. By combining complementary and substitute services, these actors create integrated offerings. This paper proposes a conceptual model which supports the analysis of ecosystems by de- composing the offering into distinct modules. Each mod- ule represents a beneficiary-provider duality with a specific value proposition and activities to be performed. It further describes, how different service modules con- tribute and may change the network-level purpose. The research follows design science and was facilitated in a consortium setup to integrate practitioners’ insights. The paper contributes by developing design principles for a service configuration model, identifying relevant activities to describe service creation, providing a logic to configure distinct services into a whole, and introducing the concept of substitutes into the discussion.

The use of persuasive technologies to improve users’ personal health outcomes are becoming increasingly pervasive in the health context. While early research on persuasive technologies highlighted the technology’s individual and societal potential, recent empirical evidence has hinted about the adverse effects of their use. However, little is known about the causes of, experiences with, and coping reactions to these adverse effects. To fill this gap, we conduct an exploratory study of wearable technologies’ adverse effects on users based on twenty-five narrative interviews. Employing a technostress lens, we find two distinct patterns–control stress and validation stress–that show that users experience these adverse effects by revolving through a circular process of technostress and relying on various mechanisms to cope with it. We describe contributions to the literature and implications for research and practice.

Digitale Nudges nutzen psychologische Prinzipien, um Nutzerverhalten im digitalen Raum zu beeinflussen. Um als Unternehmen wirksame digitale Nudges zu entwickeln, ist ein systematisches Vorgehen notwendig. Zu diesem Zweck wird in diesem Artikel die Digital Nudge Design-Methode vorgestellt, die das Entwickeln von digitalen Nudges in vier Phasen unterstützt. Die in den einzelnen Phasen angewendeten Techniken und Prozessschritte werden am Beispiel der Hero AG illustriert, die jüngst mit der Methode eigene digitale Nudges zur Nutzungsintensivierung einer Business Intelligence-Software entwickelt hat.

Wearable Activity Trackers (WATs) are often ascribed the ability to reduce health risks by promoting physical activity and healthful eating habits. However, research has shown that their use does not always lead to behavior changes. Using the affordance lens, this study investigates how WATs’ material features facilitate behavioral outcomes, as users interpret WATs in light of their personal health-related goals. Using narrative interviews with twenty-five WAT users, we found two catego-ries of affordances—learning affordances and behavior-focused affordances—leading to three behavioral outcomes: behavior change, compliance change, and remaining with the status quo. Moreover, we identified four types of users (based on their goal configurations) that actualized different affordances and showed different behavioral outcomes. While some types of users fundamentally changed their daily routines as a result of using WATs, others simply complied with technology cues or did not change their behavior at all. Our results have several implications for re-search on WATs and WATs’ design.

Wearables have the potential to optimize health-related behaviors like physical activity and nutritional intake and to improve individual health outcomes. However, researchers are still doubtful about wearables’ capacity to induce behavior change in users. Research that has built on self-efficacy theory has shown that using wearables can influence the users’ perceptions of self-efficacy and behavioral responses both positively and negatively, indicating that there is little stability over time. This study will investigate the factors that cause instability in users’ situational perceptions of self-efficacy and behavioral reactions. We plan to conduct a longitudinal, quasi-experimental field study with wearable users who self-report in weekly intervals on action-related restrictiveness, contextual restrictiveness, personal restrictiveness, situational self-efficacy, and their behavioral responses over eight weeks. Preliminary results from a pilot study with a reduced sample showed promising results. We will contribute to self-efficacy research by clarifying the factors that cause variations in behavioral responses and finding quantitative support for a situationally varying construct of self-efficacy. We will contribute to practice by deriving implications for the design of wearable devices.

Business ecosystems have recently attracted a growing interest. Scholars are working on various approaches to describe actors, their relationships, and the implications of this dynamic organizational structure. Value co-creation among these interdependent actors, including customers, based on shared technologies, standards, and rules leads to the emergence of ecosystems. Using the design science research (DSR) approach, this paper presents and evaluates propositions for value co-creation leading to the emergence of business ecosystems. They provide structuring guidelines for academic research and build the basis for the design of a model aiming to explain the actors’ collaborative activities of value co-creation in ecosystems.

Although Behavior Change Support Systems (BCSS) are gaining ground in the field of health in-terventions, we lack an empirically grounded understanding of how the behavior change tech-niques (BCTs) that are implemented in BCSS influence behavioral outcomes. Based on the self-efficacy theory, we conduct narrative interviews to investigate the process along which BCTs ap-plied in wearable activity trackers (WATs) influence users’ perceived self-efficacy and behaviors. We find three patterns that show how WATs’ BCTs feed certain information sources on which users build their self-efficacy beliefs. We identify a positive path (i.e., high self-efficacy, leading to com-pliant behavior) and a negative path (i.e., low self-efficacy, leading to non-compliant behavior) for each of these patterns. Our findings indicate that, under certain circumstances and/or at a cer-tain level of task difficulty, BCTs inflict adverse effects on users’ perceptions of their self-efficacy and their subsequent behavioral responses. Our results provide insights for theory and practice into how BCSS affect perceptions of self-efficacy and behavior change.
