Eliciting affect via immersive virtual reality: a tool for adolescent risk reduction

Insights from user experience and evaluation of a mobile health nutrition intervention for children with autism: A qualitative study

BACKGROUND

Children with autism spectrum disorder (ASD) experience high rates of atypical eating behaviours, such as food neophobia. Mobile health (mHealth) interventions have been found to improve communication, behaviour and social skills for children with ASD. However, there is limited evidence examining mHealth nutrition interventions among children with ASD.

METHODS

The present study comprised a qualitative descriptive study that used qualitative content analysis to explore parent and child experiences with a novel mHealth nutrition intervention. Ten parent-child dyads provided user feedback and evaluation of the intervention. Data collection tools included a semistructured interview guide and a quantitative questionnaire with open-ended questions. Data analysis of the interview transcripts and open-ended questionnaire responses was an iterative process that continued until saturation was achieved. Descriptive statistics were used to analyse quantitative questionnaire data.

RESULTS

Analysis of the qualitative semistructured interviews led to emergence of three themes: (1) positive intervention outcomes; (2) parent suggestions for improvement; and (3) barriers to engagement. Each theme included subthemes. Questionnaire data revealed the ability to pick rewards and the virtual character that reinforced dietary goals ("Nutrition Ninja") were the most liked components of the application. Sending messages within the application and the Nutrition Ninja game were the least liked components of the application.

CONCLUSIONS

Collectively, findings indicated that the app served as an interactive tool prompting dietary change and conversations within families. Yet, for some families, the intervention design, resistance to change or child disinterest hindered use and implementation of the intervention.

The Male Domain-Digital Game-Based Learning for Human Papillomavirus Vaccination Among Young Males

Background: Human papillomavirus (HPV) is the most common sexually transmitted disease, with the highest infection rates among those sexually active under 25. Although vaccination can reduce HPV cancers among men, public health interventions have primarily targeted females. Increased gaming rates among men provide innovative opportunities to motivate behavior change. This study sought to explore which game development and design strategies are most effective in a game for sexual health, specifically focused on HPV. We also sought to capture information relevant to preferred gaming platforms and game mechanics (health messages, avatars, and visual imagery). Materials and Methods: Twenty-two (n = 22) qualitative interviews were conducted with experts. Using grounded theory, interview data was coded, and emergent themes were identified. Results: Game mechanics most mentioned included simulation/role-playing, social interaction, narrative, and rewards. Experts felt it was important to keep the game in the context of the target audience and integrate the game into an existing game/game scenario or application. Experts also felt the game should link to external resources and enlist partnerships or collaborations with external health agencies. Moreover, while there are benefits to each gaming platform, games on mobile phones and tablets are most appropriate. Conclusion: Digital games are a nonconfrontational approach to discussing HPV and can increase knowledge/awareness and positively influence behavior change toward vaccine uptake. Digital games present a safe environment for role-playing through simulated activities without real-world consequences.

Efficacy of the Virtual Reality Intervention VR FestLab on Alcohol Refusal Self-Efficacy: A Cluster-Randomized Controlled Trial

It is currently unknown whether a virtual social environment can support young people in building their skills to overcome peer pressure when offered alcohol. This study evaluated the efficacy of the newly developed virtual reality simulation game VR FestLab on the refusal self-efficacy regarding social pressures to drink of Danish male and female students aged 15-18. VR FestLab features a party setting where adolescents can "steer" their own party experience. Eleven schools were included in a cluster-randomized controlled trial and allocated to either the intervention (n = 181) or the active control group (n = 191). Students in intervention schools played VR FestLab, while those in the control group played the VR game Oculus Quest-First Steps. The primary outcome measure was the social pressure subscale of the drinking refusal self-efficacy scale (DRSEQ-RA). The intervention effects were measured immediately after the intervention/control session (T1) and after a 6-week follow-up (T2). Data were examined using linear mixed regression models. Our study did not demonstrate a significant effect of drinking refusal self-efficacy at T1. For all secondary outcomes, we observed no substantial differences between the intervention and control groups. This study provides new insights into the feasibility and effectiveness of an innovative virtual reality alcohol prevention tool. VR FestLab can be an innovative and promising contribution to complement existing school-based alcohol prevention, but more research is needed to improve its effectiveness.

Virtual Reality-Based Alcohol Prevention in Adolescents: A Systematic Review

Virtual Reality-simulations offer new opportunities for alcohol prevention in adolescents. As an innovative medium, Virtual Reality can be attractive for the target group, and avatar-based pathways allow tailoring prevention in a gender-specific manner. However, tailoring may reproduce gender stereotypes and be exclusive. Therefore, this systematic review aims to summaries existing evidence regarding Virtual Reality-simulations for alcohol prevention targeting adolescents and to examine how gender is considered. A systematic search was conducted in seven databases. Two reviewers independently performed screening, data extraction, and quality assessment. Out of 224 search hits, four publications derived out of an Australian, a Danish, and a US-American project met the inclusion criteria. Research designs included qualitative (2), quantitative (1), and mixed-method approaches (1). Qualitative methods focused on development, evaluation, and participatory methods in the creation process, demonstrating adolescents’ involvement in Virtual Reality design. Adolescents appreciated the realism and the exposure to peer pressure and to negative alcohol consequences. Quantitative designs focused mainly on measuring alcohol-related outcomes (e.g., attitude and behavioral intentions towards binge drinking), and positive changes were found. In all studies, gender was assessed in the male-female dichotomy. Further gender-sensitive research is needed to develop and test the possibilities and pitfalls of tailoring Virtual Reality-simulations.

Head-Mounted Virtual Reality and Mental Health: Critical Review of Current Research

BACKGROUND

eHealth interventions are becoming increasingly used in public health, with virtual reality (VR) being one of the most exciting recent developments. VR consists of a three-dimensional, computer-generated environment viewed through a head-mounted display. This medium has provided new possibilities to adapt problematic behaviors that affect mental health. VR is no longer unaffordable for individuals, and with mobile phone technology being able to track movements and project images through mobile head-mounted devices, VR is now a mobile tool that can be used at work, home, or on the move.

OBJECTIVE

In line with recent advances in technology, in this review, we aimed to critically assess the current state of research surrounding mental health.

METHODS

We compiled a table of 82 studies that made use of head-mounted devices in their interventions.

RESULTS

Our review demonstrated that VR is effective in provoking realistic reactions to feared stimuli, particularly for anxiety; moreover, it proved that the immersive nature of VR is an ideal fit for the management of pain. However, the lack of studies surrounding depression and stress highlight the literature gaps that still exist.

CONCLUSIONS

Virtual environments that promote positive stimuli combined with health knowledge could prove to be a valuable tool for public health and mental health. The current state of research highlights the importance of the nature and content of VR interventions for improved mental health. While future research should look to incorporate more mobile forms of VR, a more rigorous reporting of VR and computer hardware and software may help us understand the relationship (if any) between increased specifications and the efficacy of treatment.

Utility of virtual reality environments to examine physiological reactivity and subjective distress in adults who stutter

PURPOSE

Virtual reality environments (VREs) allow for immersion in speaking environments that mimic real-life interactions while maintaining researcher control. VREs have been used successfully to engender arousal in other disorders. The purpose of this study was to investigate the utility of virtual reality environments to examine physiological reactivity and subjective ratings of distress in persons who stutter (PWS).

METHOD

Subjective and objective measures of arousal were collected from 10PWS during four-minute speeches to a virtual audience and to a virtual empty room.

RESULTS

Stuttering frequency and physiological measures (skin conductance level and heart rate) did not differ across speaking conditions, but subjective ratings of distress were significantly higher in the virtual audience condition compared to the virtual empty room.

CONCLUSION

VREs have utility in elevating subjective ratings of distress in PWS. VREs have the potential to be useful tools for practicing treatment targets in a safe, controlled, and systematic manner.
