A Meta-Analysis of the Efficacy of Virtual Reality and In Vivo Exposure Therapy as Psychological Interventions for Public Speaking Anxiety

Perfectionism as a predictor of change in digital self-guided interventions for public speaking anxiety in adolescents: A secondary analysis of a four-armed randomized controlled trial

Public Speaking Anxiety (PSA) interventions targeting adolescents exist; however, not all gain improvement. This exploratory study investigated whether PSA interventions resulted in a decrease in perfectionism and whether pre-treatment level and changes in perfectionism moderated the effects on PSA and social anxiety. The sample consisted of 100 adolescents from junior high schools randomized to four groups: 1) VR only (n = 20), 2) VR + online exposure program (n = 20), 3) online psychoeducation and online exposure program (n = 40), 4) waitlist and online psychoeducation program (n = 20). Self-reported symptoms of PSA, social anxiety, and perfectionism were measured at pre, week 3, post, and 3-months follow-up. Level and change in outcome variables were analyzed using latent growth curve modeling. Results revealed that the interventions did not lead to a reduction in perfectionism. Reduction in perfectionism was associated with a larger reduction in all outcome measures from post to follow-up. No interaction was found between pre-treatment perfectionism and PSA symptoms. High pre-treatment levels of perfectionism were associated with poorer outcomes on social anxiety symptoms from post to follow-up for online exposure groups. The results indicate that one should assess and address high pre-treatment levels of perfectionism during PSA interventions.

Patient Perceptions of In Vivo Versus Virtual Reality Exposures for the Treatment of Anxiety Disorders: Cross-Sectional Survey Study

BACKGROUND

Psychotherapy, and particularly exposure therapy, has been proven to be an effective treatment for many anxiety disorders, including social and specific phobias, as well as posttraumatic stress disorders. Currently, exposures are underused and mostly delivered in vivo. Virtual reality exposure therapy (VRET) offers a more flexible delivery mechanism that has the potential to address some of the implementation barriers of in vivo exposures while retaining effectiveness. Yet, there is little evidence on how patients perceive different exposure therapy methods.

OBJECTIVE

This study aims to explore the perceptions of individuals with anxiety disorders toward in vivo and VRET. Our findings can inform therapists about the degree of patient interest in both methods while exploring the demand for VRET as an alternative and novel treatment approach.

METHODS

Web-based survey assessing the (1) interest in, (2) willingness to use, (3) comfort with, (4) enthusiasm toward, and (5) perceived effectiveness of exposure therapy when delivered in vivo and through VR. Participants included individuals with specific phobia, social phobia, posttraumatic stress disorder, or acute stress disorder or reaction. Participants were presented with educational videos about in vivo and VRET and asked to provide their perceptions quantitatively and qualitatively through a rated scale and free-text responses.

RESULTS

In total, 184 surveys were completed and analyzed, in which 82% (n=151) of participants reported being willing to receive in vivo exposures and 90.2% (n=166) reported willingness to receive VRET. Participants reported higher interest in, comfort with, enthusiasm toward, and perceived effectiveness of VRET compared to in vivo. Most reported in vivo concerns were linked to (1) increased anxiety, (2) feelings of embarrassment or shame, and (3) exacerbation of current condition. Most reported VRET concerns were linked to (1) risk of side effects including increased anxiety, (2) efficacy uncertainty, and (3) health insurance coverage. The most frequently mentioned VRET benefits include (1) privacy, (2) safety, (3) the ability to control exposures, (4) comfort, (5) the absence of real-life consequences, (6) effectiveness, and (7) customizability to a wider variety of exposures.

CONCLUSIONS

On average, our participants expressed positive perceptions toward exposure therapy, with slightly more positive perceptions of VRET over in vivo exposures. Despite valid personal concerns and some misconceptions, our findings emphasize that VRET provides an opportunity to get much-needed therapy to patients in ways that are more acceptable and less concerning.

The first steps in facing your fears: The acceptability of virtual reality and in vivo exposure treatment for specific fears

Phobic individuals are often reluctant to engage in exposure in vivo (IVE). We examined whether providing exposure in virtual reality (VRE) can increase the acceptability. In Study 1, we provided 186 fearful participants with (hypothetical) VRE and IVE treatment offers and examined their willingness to engage in treatment, estimated success, negative beliefs, acceptance/refusal and their preference. Almost 70 % preferred VRE over IVE and acceptance rates were higher for the VRE offer (58 %) than for IVE (35 %). Although participants held fewer negative beliefs about VRE, they did rate IVE as slightly more successful. In Study 2, we examined whether VRE can serve as a stepping stone to IVE in a sample of 102 spider fearful individuals. Willingness to engage, estimated success and negative beliefs about IVE were assessed before and after VRE. After VRE, participants rated IVE as more successful, but were not more willing to engage in IVE, nor were they more inclined to accept an IVE offer. No decreases in negative beliefs were observed. In conclusion, VRE is deemed more acceptable than IVE and could lower refusal rates, hereby resulting in more phobic individuals receiving treatment. Future research should shed light on underlying motivations and associations.

The Symbiosis of Virtual Reality Exposure Therapy and Telemental Health: A Review

Phobias and related anxiety are common and costly mental health disorders. Experts anticipate the prevalence of phobias will increase due to the COVID-19 pandemic. Exposure therapies have been established as effective and reliable treatments for anxiety, including recent innovations in virtual reality-based exposure therapy (VRET). With the recent advent of telemental health (TMH), VRET is poised to become mainstream. The combination of VRET and TMH has the potential to extend provider treatment options and improve patient care experiences. In this narrative review, we describe how recent events have accelerated VRET + TMH, identify barriers to VRET + TMH implementation, and discuss strategies to navigate those barriers.
