Digital voice assistants (DVAs) are application programs that can understand and interpret natural language voice commands. They are embedded in various products like smartphones and smart speakers and have thus become integral in everyday life, interpersonal communications, and social relationships. Despite users tend to humanize DVAs, emotions that arise in interpersonal interactions such as self-conscious emotions (i.e., pride, shame, guilt, and vicarious embarrassment) and their influence on human-machine interaction remain unstudied. Grounding on regulatory focus theory, we argue that these emotions are fundamental for promoting or preventing future DVA use. Additionally, drawing on social influence theory, we contend that the influence of self-conscious emotions on continuous DVA use varies across specific usage situations. Thus, we extend the expectation-confirmation model with self-conscious emotions and empirically compare user reactions between different social scenarios (alone and with friends in private vs. public places). Analyzing 860 DVA user responses through structural equation modeling and multigroup analysis, our findings reveal that pride consistently positively influences continuance intention across all social contexts. Furthermore, shame acts as an important inhibitor of continuance intentions in public, while guilt inhibits continuance intentions in private places. Vicarious embarrassment, however, does not exhibit significant effects in any scenario. These results carry valuable implications for both research and management in understanding and optimizing DVA user experiences.

Hand hygiene compliance is well known as an important measure in preventing the transmission of infectious disease. Even though general public was aware of this health message during the COVID-19 pandemic, sustaining such personal hygiene behavior is difficult. While personal hygiene virtual reality intervention via an immersive experience has been found as an effective health promotion strategy, its prior implementation was mostly among healthcare workers but not among people in the community. Using a mixed methods approach, this study draws on the theory of planned behaviors to design two experimental studies for testing this interventional approach's sustainability and applicability to the general population. The result confirmed the virtual reality scenario with both presence and embodiment demonstrated a more sustainable treatment effect in boosting individual's self-efficacy over other experimental arms. Post-hoc analysis revealed the reduction of perceived barrier after exposure to immersive environment was attributable to treatment effect. The findings were reconfirmed through triangulation in the qualitative post-intervention interviews. Finally, we highlight the theoretical and practical implication of the study for the future development of personal hygiene immersive environment-based intervention.

Background

Obesity is a global health issue affecting over 2 billion people. Mobile health apps, specifically nutrition apps, have been identified as promising solutions to combat obesity. However, research on adherence to nutrition apps is scarce, especially for publicly available apps without monetary incentives and personal onboarding. Understanding factors associated with adherence is essential to improve the efficacy of these apps. This study aims to identify such factors by analyzing a large dataset of a free and publicly available app (“MySwissFoodPyramid”) that promotes healthy eating through dietary self-monitoring and nutrition literacy delivered via a conversational agent.

Methods

A retrospective analysis was conducted on 19,805 users who used the app for at least two days between November 2018 and May 2022. Adherence was defined as completing a food diary by tracking dietary intake over a suggested period of three days. Users who finished multiple diaries were considered long-term adherent. The associations between the day and time of installation, tutorial use, reminder use, and conversational agent choice were examined regarding adherence, long-term adherence, and the number of completed diaries.

Results

Overall, 66.8% of included users were adherent, and 8.5% were long-term adherent. Users who started the intervention during the day (5 a.m.–7 p.m.) were more likely to be adherent and completed more diaries. Starting to use the intervention between Sunday and Wednesday was associated with better adherence and a higher number of completed diaries. Users who chose the female conversational agent were more likely to be adherent, long-term adherent, and completed more diaries. Users who skipped the tutorial were less adherent and completed fewer diaries. Users who set a follow-up reminder were more likely to be long-term adherent and completed more diaries.

Conclusions

This study demonstrates the potential of digital health interventions to achieve comparably high adherence rates, even without monetary incentives or human-delivered support. It also reveals factors associated with adherence highlighting the importance of app tutorials, customizable reminders, tailored content, and the date and time of user onboarding for improving adherence to mHealth apps. Ultimately, these findings may help improve the effectiveness of digital health interventions in promoting healthy behaviors.

Research on the use of digital devices to conduct tasks across work and non-work domains (i.e., boundary-crossing ICT use) grows rapidly. To gain an overview of this expanding field, we conducted a systematic search in 14 databases (e.g., WoS, PsycINFO) for studies examining the outcomes of performing 1) work-related tasks during non-work time and 2) non-work tasks during work time. After screening 17,388 abstracts, 398 were read in full text, and 159 publications were included. Most studies used cross-sectional interviews or self-report survey data of employees in high-income countries. The work-family interface, individual work and health outcomes were commonly studied, while family and organizational outcomes received little attention. Moreover, research with a multilevel perspective and studies examining objective outcomes (e.g., divorce, sick leave) were scarce and the performance of non-work tasks during work time was often ignored. Despite the burgeoning literature, there is an urgent need to arrive at a common conceptualization and operationalization of boundary-crossing ICT use to be able to compare findings across studies and disciplines. We suggest a new definition and future agenda to contribute to a deeper understanding of the field.

Voice notes, spoken messages recorded and sent via smartphones, have become a widespread means of communication. A likely consequence of this situation is that voice note users become more frequently exposed to recordings of their own voices (self-voices). This correlational study examined if frequent exposure to recordings of the self-voice via voice note replay was associated with improved self-voice recognition (accuracy and response latency) and self-voice liking. Participants (N = 128), regular voice note users, reported voice note replay frequency. They also reported self-voice satisfaction/liking. Finally, participants completed a novel self-voice recognition task, where, across 20 trials, they identified whether a recording was them (self-voice) or not (non-self-voice). The tendency to frequently replay voice notes was positively correlated with self-voice liking and recognition accuracy. These findings may have implications for the treatment of social anxiety disorder and auditory verbal hallucinations.

The main aim of this research was to explore how the digital proficiency of internal auditors impact the relationship between adopting cloud-based accounting and the digital efficiency of internal auditors in Jordanian-listed industrial firms. 98 questionnaires, gathered from internal audit managers in these companies, underwent analysis using Statistical Package for Social Sciences (SPSS) using descriptive-analytical methods. Results indicated that adopting cloud-based accounting significantly influences the effectiveness of internal auditors in these Jordanian-listed industrial companies. Moreover, the study found that the digital proficiency of internal auditors positively affects how much cloud-based accounting adoption impacts their effectiveness. These findings hold importance for regulators and decision-makers, offering insights to shape potential new regulations aimed at enhancing the use of cloud-based accounting in internal audit departments within Jordan's industrial sector. This could ultimately help internal auditors in overseeing public funds. Given the extensive impact of cloud technology on modern business, it's crucial to understand how these innovations can improve the precision and benefits of internal audit functions. Exploring the factors that drive the implementation of cloud technologies in internal audit is also essential. Notably, this study represents the initial attempt to examine existing research on the role of cloud-based accounting in enhancing internal audit effectiveness concerning the digital proficiency of auditors within Jordan's industrial sector.

People are increasingly open to sharing personal data collected by wearables, while concerns have emerged on how companies, governments and organisations process this data. This paper applies Nissenbaum's theory of contextual integrity to explore the perceived appropriateness of information flows linked to wearables. A vignette study was conducted (N = 500) to examine the influence of the type of data shared, its purpose, and the sender, on the appropriateness of different wearables' information flow scenarios. Results revealed a significant impact of information type, sharing purpose, and sender on the perceived appropriateness of data sharing. Notably, data collected for research purposes or to develop new functionalities was deemed most appropriate, while data used for advertising was viewed unfavourably. Further, the user-controlled sharing received higher appropriateness ratings. This research underscores the need for meaningful consent in data sharing and suggests that manufacturers of wearable devices should utilise user agency to supplement information flow automation based on societal and contextual privacy norms.

Imagery rescripting (IR) is a cognitive-experiential technique used for the treatment of various mental conditions through the re-working of aversive memories. It has been widely applied in psychotherapy to address Post-Traumatic Stress Disorder (PTSD) and personality, anxiety, and eating disorders. Despite usually being effective, IR's underlying mechanism has not been clarified yet. Consistently, different assumptions may correspond to different IR versions and outcomes. Among these versions, active IR (AIR) – meaning a rescripting where the patient is the active ‘rescriptor’ – seems to have particularly positive effects. So far, IR use has been almost exclusively limited to in vivo settings. But the increasing availability of Virtual Reality (VR) in the last few years has favored the in virtuo implementation of safe and effective psychological treatments. On these grounds – and given that virtual scenarios can offer the possibility to perform any necessary actions and even more than real ones – we hypothesize that implementing AIR in VR can be effective in treating psychological conditions. As a preliminary evaluation of this assumption, we systematically searched the literature and reviewed the studies concerning VR realizations of AIR addressing mental issues. Our literature analysis provides the first evidence supporting this hypothesis, yet urging further research and testing.

Adolescence is a critical developmental period of biological and social change during which 1 in 3 youth experience significant anxiety symptoms. The social-emotional lives of the majority of adolescents are largely conducted via digital media use (DMU; e.g., social media, text messaging). Yet the past decade of research on DMU and anxiety has yielded mixed results (e.g., Keles et al., 2020 review), leaving the complex role that DMU might play in the emergence and maintenance of anxiety poorly understood. A key step forward is to leverage psychophysiology to identify individual differences in cognitive and emotional processes that confer vulnerability to potential negative effects of DMU. Further, given the ubiquity of DMU, a greater focus is needed on measurements that move beyond sheer frequency to capture DMU in comparison to face-to-face (FTF) social interactions. This study examined attention bias (AB), characterized by selective and exaggerated attention toward or away from threat, as a moderator of the link between DMU and anxiety in adolescents (N = 75; 42 female) aged 12–14 years (M = 13.28, SD = 0.87). AB was indexed during a dot probe task using reaction time metrics (i.e., trial-level bias) and via ERPs capturing attentional selection and discrimination (N170) and cognitive control (N2) to threat compared to neutral faces. AB moderated associations between DMU and anxiety. A greater preference to use DMU vs FTF predicted greater anxiety among those with a greater behavioral bias away from threat, blunted N170, and blunted N2 in the presence of threat. Future research should examine potential causal and bidirectional links between DMU and anxiety and explore whether preferences for technology-mediated interactions and individual differences in threat processing increase risk.

The media's adherence to “if it bleeds, it leads” has resulted in global dominance of negative news (e.g., stories of corruption, fraud, shootings, terrorism, and war). The appetite for negative news is fueled by negativity bias, which compels people to prioritize negative over positive stories. This cross-cultural study, inspired by media effect theories such as Cultivation Theory, explored the links between problematic consumption of negative news (doomscrolling), existential anxiety, pessimistic views about human nature, and belief about a just world in two distinct cultures. Participants included convenience samples of Iranian (n = 620) and American (n = 180) university-student social media users. Doomscrolling was associated with elevated levels of existential anxiety in both samples. Additionally, misanthropy was positively associated with doomscrolling only in the Iranian sample. Aligned with the Media-induced PTSD Hypothesis and the Shattered Assumption Theory, our findings suggest that prolonged exposure to negative news can contribute to the development of existential anxiety. Current news framing with its overemphasis on negativity could fuel doomscrolling-inspired existential concerns.
