Assessment and treatment of mental health conditions in children and adolescents: A systematic scoping review of how virtual reality environments have been used

BACKGROUND

There is growing interest in the use of virtual reality environments (VREs) in psychological treatment and assessment. Most research has focused on the application of VREs in adult psychological disorders with fewer studies focusing on its applicability with children and adolescents. A systematic scoping review was undertaken of research assessing how VREs have been used in the treatment and assessment of childhood mental health disorders to provide an overview of the current state of the literature and identify future research directions.

METHOD

Systematic searches of online databases were conducted in PsycInfo, PubMed, Embase, Scopus, and Web of Science.

RESULTS

Eleven studies met eligibility criteria and were included in this review, with the majority focusing on VRE interventions for anxiety-related disorders. There is also emerging support for VRE deep breathing training for anxiety, VRE assisted treatment of internet gaming disorder and anorexia nervosa, and VRE assessment of body image evaluation in anorexia nervosa. Most studies were pilot and feasibility studies with only three randomised-controlled trials (RCT).

CONCLUSIONS

The current literature shows some promise for the use of VRE assessments and interventions of childhood mental health problems, particularly for anxiety-related disorders such as social anxiety and specific phobias. However, high-quality RCTs are now needed to establish effectiveness of VREs in this population, and how it compares to existing evidence-based approaches, given its promise to improve both engagement and outcomes.

Looking fear in the eye: Gamified virtual reality exposure towards spiders for children using attention based feedback

Many children around the globe suffer from spider phobia. Virtual reality exposure therapy is an effective phobia treatment, but so far predominantly tailored for adults. A gamified approach utilizing gaze interaction would allow for a more child-friendly and engaging experience, and provide the possibility to foster working mechanisms of exposure therapy. We developed an application in which children make spiders change in positively connoted ways (e.g., make them dance or shrink) if sufficient visual attention towards them is captured via eye tracking. Thereby, motivation for and positive affects during exposure towards spiders are aspired. In this pilot study on 21 children without (n = 11) and with fear of spiders (n = 10), we examined positive and negative affect during exposure to a virtual spider and to different gaze-related transformations of the spider within a quasi-experimental design. Within a one-group design, we additionally examined fear of spiders in spider fearful children before and one week after the intervention. We found that significantly more positive than negative affect was induced by the spiders' transformations in children without and with fear of spiders. Fear of spiders was furthermore significantly reduced in spider-fearful children, showing large effect sizes (d > .80). Findings indicate eligibility for future clinical use and evaluation in children with spider phobia.

Digital Health Interventions for Delivery of Mental Health Care: Systematic and Comprehensive Meta-Review

BACKGROUND

The COVID-19 pandemic has shifted mental health care delivery to digital platforms, videoconferencing, and other mobile communications. However, existing reviews of digital health interventions are narrow in scope and focus on a limited number of mental health conditions.

OBJECTIVE

To address this gap, we conducted a comprehensive systematic meta-review of the literature to assess the state of digital health interventions for the treatment of mental health conditions.

METHODS

We searched MEDLINE for secondary literature published between 2010 and 2021 on the use, efficacy, and appropriateness of digital health interventions for the delivery of mental health care.

RESULTS

Of the 3022 records identified, 466 proceeded to full-text review and 304 met the criteria for inclusion in this study. A majority (52%) of research involved the treatment of substance use disorders, 29% focused on mood, anxiety, and traumatic stress disorders, and >5% for each remaining mental health conditions. Synchronous and asynchronous communication, computerized therapy, and cognitive training appear to be effective but require further examination in understudied mental health conditions. Similarly, virtual reality, mobile apps, social media platforms, and web-based forums are novel technologies that have the potential to improve mental health but require higher quality evidence.

CONCLUSIONS

Digital health interventions offer promise in the treatment of mental health conditions. In the context of the COVID-19 pandemic, digital health interventions provide a safer alternative to face-to-face treatment. However, further research on the applications of digital interventions in understudied mental health conditions is needed. Additionally, evidence is needed on the effectiveness and appropriateness of digital health tools for patients who are marginalized and may lack access to digital health interventions.

Virtual Reality Exposure Treatment in Phobias: a Systematic Review

We compare the relative efficacy of virtual reality therapy exposure (VRET) versus in vivo therapy exposure among individuals suffering from phobias. A systematic search was completed up to 03 April 2020, using the following databases: ACM Digital Library, ResearchGate, IEEE, Science Direct, MIT PressJournals, Center for Direct Scientific Communication (CCSD) and Mary Ann Liebert Publishers. Five authors searched the databases using the following terms: Virtual Reality, Phobia, Mental health, Computing, Therapy, HMD, CAVE, Virtual ambient, in virtuo, Avoidance, Exposure, VRET, in vivo, Anxiety, Agoraphobia, Social Phobia, Stimuli, Cognitive-behaviour. All studies that evaluate the effect of in virtuo exposure towards phobia rehabilitation were selected. By reviewing the article, each author then applied the inclusion and exclusion criteria, and 30 articles were selected. Data extracted included the number of samples, amount of sessions, study variables that may affect the final outcome, therapy technology. The data provided was synthesized using a meta-analysis based on the results. The results demonstrated a positive outcome of Virtual Reality Exposure Treatment in the treatment of most phobias. In contrast, some of these treatments did not work for a few specific phobias in which the standard procedures were more effective. The findings suggest that for some specific phobias treatment, Virtual Reality Exposure Treatment does not reach the in vivo exposure level of immersion and presence. Further research is needed to perform studies with higher-dimension samples, since many papers report a low sample size and that is probably why many of them have inconclusive results.

Real and virtual classrooms can trigger the same levels of stuttering severity ratings and anxiety in school-age children and adolescents who stutter

PURPOSE

Many school-age children and adolescents who stutter experience the fear of public speaking. Treatment implications include the need to address this problem. However, it is not always possible to train repeatedly in front of a real audience. The present study aimed to assess the relevance of using a virtual classroom in clinical practice with school-age children and adolescents who stutter.

METHODS

Ten children and adolescents who stutter (aged 9-17 years old) had to speak in three different situations: in front of a real audience, in front of a virtual class and in an empty virtual apartment using a head-mounted display. We aimed to assess whether the self-rated levels of anxiety while speaking in front of a virtual audience reflect the levels of anxiety reported while speaking in front of a live audience, and if the stuttering level while speaking to a virtual class reflects the stuttering level while speaking in real conditions.

RESULTS

Results show that the real audience creates higher anticipatory anxiety than the virtual class. However, both the self-reported anxiety levels and the stuttering severity ratings when talking in front of a virtual class did not differ from those observed when talking to a real audience, and were significantly higher than when talking in an empty virtual apartment.

CONCLUSION

Our results support the feasibility and relevance of using a virtual classroom to expose school-age children and adolescents who stutter to a feared situation during cognitive behavioral therapy targeting the fear of public speaking.

Spider Phobia: Neural Networks Informing Diagnosis and (Virtual/Augmented Reality-Based) Cognitive Behavioral Psychotherapy-A Narrative Review

Recent fMRI studies on specific animal phobias, particularly spider phobia (arachnophobia), have identified a large variety of specific brain regions involved in normal and disturbed fear processing. Both functional and structural brain abnormalities have been identified among phobic patients. Current research suggests that both conscious and subconscious fear processing play a crucial role in phobic disorders. Cognitive behavioral therapy has been identified as an effective treatment for specific phobias and has been associated with neuroplastic effects which can be evaluated using current neuroimaging techniques. Recent research suggests that new approaches using virtual (VR) or augmented reality (AR) tend to be similarly effective as traditional "in vivo" therapy methods and could expand treatment options for different medical or individual scenarios. This narrative review elaborates on neural structures and particularities of arachnophobia. Current treatment options are discussed and future research questions are highlighted.

Technology Use for Adolescent Health and Wellness

As avid users of technology, adolescents are a key demographic to engage when designing and developing technology applications for health. There are multiple opportunities for improving adolescent health, from promoting preventive behaviors to providing guidance for adolescents with chronic illness in supporting treatment adherence and transition to adult health care systems. This article will provide a brief overview of current technologies and then highlight new technologies being used specifically for adolescent health, such as artificial intelligence, virtual and augmented reality, and machine learning. Because there is paucity of evidence in this field, we will make recommendations for future research.

Cyber Health Psychology: The use of new technologies at the service of psychologycal well being and health empowerment

Man and technology seem to co-evolve into a process of reciprocal conditioning. On the one hand, the man modifies (and evolves) the technology according to his needs, on the other the technology revolutionates the man and the way in which it lives. Psychology, therefore, as a discipline afferent to the human sciences, is called to take an interest in this relationship and to understand its complexity. A fundamental role in this sense is covered by "cyberpsychology" which investigates all those psychological phenomena that are associated with technology and aims to analyse the processes of change triggered by the interaction between man and the new media. From the psychological point of view, if on the one hand it is important to understand how man changes in contact with the new technologies and to what problems he is meeting. On the other hand, there is a need to understand how new technologies, given their transformative potential, can find a place within the therapeutic practice. In this regard, some of the technologies used in the clinical field have been analysed including: virtual reality, biosensors, artificial intelligence and affective computing. With the aim of understanding to what extent and how technological progress and the emergence of new technologies can contribute and generate value within the psychological panorama. Following the PRISMA statement a bibliographic research was carried out, which provided for consultation of the Medline and PsycINFO databases. The criteria according to which works have been selected rather than others refer to their precision and sensitivity with which they propose to treat technological applications in the field of health psychology and from this the emergence of the new theme "CYBER HEALTH PSYCHOLOGY". The results of the research suggest that the integrated use of psychological techniques and new technologies is extremely productive in terms of potential improvement of health and therefore of "health empowerment". In this vision, new technologies are not intended to replace traditional procedures but to integrate them by making available features and potential that man does not have in nature. Given the great potential of the instruments analyzed that still today continue to evolve and refine it is advisable to know them, validate their effectiveness and adapt our operational models to new realities.

Allocating less attention to central vision during vection is correlated with less motion sickness

Visually induced motion sickness (VIMS) is a common discomfort response associated with vection-provoking stimuli. It has been suggested that susceptibility to VIMS depends on the ability to regulate visual performance during vection. To test this, 29 participants, with VIMS susceptibility assessed by Motion Sickness Susceptibility Questionnaire, were recruited to undergo three series of sustained attention to response tests (SARTs) while watching dot pattern stimuli known to provoke roll-vection. In general, SARTs performance was impaired in the central visual field (CVF), but improved in peripheral visual field (PVF), suggesting the reallocation of attention during vection. Moreover, VIMS susceptibility was negatively correlated with the effect sizes, suggesting that participants who were less susceptible to VIMS showed better performance in attention re-allocation. Finally, when trained to re-allocation attention from the CVF to the PVF, participants experienced more stable vection. Findings provide a better understanding of VIMS and shed light on possible preventive measures. Practitioner Summary: Allocating less visual attention to central visual field during visual motion stimulation is associated with stronger vection and higher resistance to motion sickness. Virtual reality application designers may utilise the location of visual tasks to strengthen and stabilise vection, while reducing the potential of visually induced motion sickness.

[What do virtual reality tools bring to child and adolescent psychiatry?]

Virtual reality is a relatively new technology that enables individuals to immerse themselves in a virtual world. It offers several advantages including a more realistic, lifelike environment that may allow subjects to "forget" they are being assessed, allow a better participation and an increased generalization of learning. Moreover, the virtual reality system can provide multimodal stimuli, such as visual and auditory stimuli, and can also be used to evaluate the patient's multimodal integration and to aid rehabilitation of cognitive abilities. The use of virtual reality to treat various psychiatric disorders in adults (phobic anxiety disorders, post-traumatic stress disorder, eating disorders, addictions…) and its efficacy is supported by numerous studies. Similar research for children and adolescents is lagging behind. This may be particularly beneficial to children who often show great interest and considerable success on computer, console or videogame tasks. This article will expose the main studies that have used virtual reality with children and adolescents suffering from psychiatric disorders. The use of virtual reality to treat anxiety disorders in adults is gaining popularity and its efficacy is supported by various studies. Most of the studies attest to the significant efficacy of the virtual reality exposure therapy (or in virtuo exposure). In children, studies have covered arachnophobia social anxiety and school refusal phobia. Despite the limited number of studies, results are very encouraging for treatment in anxiety disorders. Several studies have reported the clinical use of virtual reality technology for children and adolescents with autistic spectrum disorders (ASD). Extensive research has proven the efficiency of technologies as support tools for therapy. Researches are found to be focused on communication and on learning and social imitation skills. Virtual reality is also well accepted by subjects with ASD. The virtual environment offers the opportunity to administer controlled tasks such as the typical neuropsychological tools, but in an environment much more like a standard classroom. The virtual reality classroom offers several advantages compared to classical tools such as more realistic and lifelike environment but also records various measures in standardized conditions. Most of the studies using a virtual classroom have found that children with Attention Deficit/Hyperactivity Disorder make significantly fewer correct hits and more commission errors compared with controls. The virtual classroom has proven to be a good clinical tool for evaluation of attention in ADHD. For eating disorders, cognitive behavioural therapy (CBT) program enhanced by a body image specific component using virtual reality techniques was shown to be more efficient than cognitive behavioural therapy alone. The body image-specific component using virtual reality techniques boots efficiency and accelerates the CBT change process for eating disorders. Virtual reality is a relatively new technology and its application in child and adolescent psychiatry is recent. However, this technique is still in its infancy and much work is needed including controlled trials before it can be introduced in routine clinical use. Virtual reality interventions should also investigate how newly acquired skills are transferred to the real world. At present virtual reality can be considered a useful tool in evaluation and treatment for child and adolescent disorders.

The scientific legacy of Little Hans and Little Albert: future directions for research on specific phobias in youth

We review issues associated with the phenomenology, etiology, assessment, and treatment of specific phobias in children and adolescents and provide suggestions for future research and clinical practice. In doing so, we highlight the early case studies of Little Hans and Little Albert and the advances that have been made following the publication of these seminal cases. In recent years, we have witnessed a deeper understanding of the etiology of specific phobias and developed a rich array of evidence-based assessments and treatments with which to address specific phobias in youth. Although much has been accomplished in this area of inquiry, we also note that much remains to be done before we can advance more fully our understanding, assessment, and treatment of specific phobias in youth. It will be important for future work to build more firmly on these developments and to better determine the moderators and mediators of change with our evidence-based treatments and to more vigorously pursue their dissemination in real-word settings.

A meta-analysis on the relationship between self-reported presence and anxiety in virtual reality exposure therapy for anxiety disorders

In virtual reality exposure therapy (VRET) for anxiety disorders, sense of presence in the virtual environment is considered the principal mechanism that enables anxiety to be felt. Existing studies on the relation between sense of presence and level of anxiety, however, have yielded mixed results on the correlation between the two. In this meta-analysis, we reviewed publications on VRET for anxiety that included self-reported presence and anxiety. The comprehensive search of the literature identified 33 publications with a total of 1196 participants. The correlation between self-reported sense of presence and anxiety was extracted and meta-analyzed. Potential moderators such as technology characteristics, sample characteristics including age, gender and clinical status, disorder characteristics and study design characteristics such as measurements were also examined. The random effects analysis showed a medium effect size for the correlation between sense of presence and anxiety (r = .28; 95% CI: 0.18-0.38). Moderation analyses revealed that the effect size of the correlation differed across different anxiety disorders, with a large effect size for fear of animals (r = .50; 95% CI: 0.30-0.66) and a no to small effect size for social anxiety disorder (r = .001; 95% CI: -0.19-0.19). Further, the correlation between anxiety and presence was stronger in studies with participants who met criteria for an anxiety disorder than in studies with a non-clinical population. Trackers with six degrees of freedom and displays with a larger field of view resulted in higher effect sizes, compared to trackers with three degrees of freedom and displays with a smaller field of view. In addition, no difference in effect size was found for the type of presence measurement and the type of anxiety measurement. This meta-analysis confirms the positive relation between sense of presence and anxiety and demonstrates that this relation can be affected by various moderating factors.
