ABSTRACT

BACKGROUND AND OBJECTIVES: Negative mental imagery appears to play a role in anxiety disorders and can involve aversive memories or anticipated future threats. Modulating aversive memories through imagery rescripting generally reduces negative memory appraisals and associated anxiety. This pre-registered two-day analog study investigated whether imagery rescripting of aversive memories also reduces negative imagery of future threats. METHODS: On Day 1, socially anxious individuals (N = 52) were randomly assigned to imagery rescripting of an aversive memory or progressive relaxation (control condition). Before each intervention, they were asked to imagine a feared social situation that may happen in their future and evaluate this situation. They also rated the aversive memory before and after the intervention phase. The feared future situation was again evaluated at follow-up on Day 2. RESULTS: Unexpectedly, no group differences were found on the main outcome measures. That is, negative memory appraisals reduced after both interventions. Likewise, in both groups, negative details decreased, and positive details increased in prospective mental imagery, and anxiety and avoidance towards the imagined event decreased. On the exploratory measures, the imagery rescripting group showed increased positive appraisals of memory and future threat, and decreased negative future-threat appraisals, compared to the progressive relaxation group. LIMITATIONS: No passive control group was included, so potential time or placebo effects cannot be precluded. CONCLUSIONS: The interventions had similar effects on the main outcomes and influenced mental imagery of future threats. Some differences were found on the exploratory measures that warrant further investigation with a passive control condition.

ABSTRACT

Distressing mental images are common in anxiety disorders and can make it difficult for patients to confront feared situations. This study examined whether imagery rescripting focused on a feared social situation prepares participants to engage in a feared situation. Sixty healthy individuals were asked to formulate a behavioral experiment to test negative beliefs about a social situation they feared. They were assigned to one of two groups: imagery rescripting focused on the feared outcome of the behavioral experiment or no imagery rescripting (i.e., a break). All participants were then asked to complete ratings scales and to conduct the behavioral experiment. Before the behavioral experiment, the imagery rescripting condition, compared to the control condition, showed reduced anticipated probability and severity of the feared outcome, lower anxiety and helplessness levels, and increased willingness to conduct the behavioral experiment. Imagery-based interventions focused on feared outcomes seem promising to prepare anxious individuals to engage in treatment.

ABSTRACT

Exposure therapy is the recommended treatment for anxiety disorders, but many anxious individuals are unwilling to expose themselves to feared situations. Episodic simulation of future situations contributes to adaptive emotion regulation and motivates behavior. This study investigated whether future-oriented positive mental imagery reduces anticipatory anxiety and distress during exposure, and increases exposure willingness and duration. Forty-three individuals with moderate public speaking anxiety were randomized to a standardized positive mental imagery exercise about future public speaking or no-task. All participants were then asked to present in a virtual reality environment. Anticipatory anxiety reduced in the positive mental imagery group, but not in the control group. Additionally, the positive mental imagery group reported lower distress during exposure than the control group, but groups did not differ in exposure willingness. Due to limited variance, effects on exposure duration could not be tested. Future-oriented positive mental imagery is promising to prepare individuals for exposure to previously avoided situations.

ABSTRACT

In recent years the development of new virtual environments has been qualitatively high and fast at the same time, but the dissemination of virtual reality (VR) in clinical practice is still scarce. The aim of this review is to give an insight into the state of the art of the use of VR as an assessment tool and treatment intervention in anxiety and related disorders as posttraumatic stress disorder and obsessive-compulsive disorders. Besides an overview into the efficacy of VR, a summary will be given on assumed working mechanisms in virtual reality exposure therapy and how this aligns with current theoretical models. Further, it will be discussed how VR is accepted by patients and research into the reluctance of therapist to use this technology during treatment with focus on the therapeutic alliance and how it may be influenced by the use of VR. Finally, we discuss clinical and future issues as, for example, dissemination into clinical practice and what VR has to offer therapists in future. This not only in adult population but as well in younger patients, as young adolescents VR has a great potential as it connects easily with its playful elements to this population and might be a low threshold step to offer treatment or preventive interventions.

ABSTRACT

Initially designed for the treatment of phobias, the use of virtual reality in phobic disorders has expanded to other mental health disorders such as posttraumatic stress disorder, substance-related disorders, eating disorders, psychosis, and autism spectrum disorder. The goal of this review is to provide an accessible understanding of why this approach is important for future practice, given its potential to provide clinically relevant information associated with the assessment and treatment of people suffering from mental illness. Most of the evidence is available for the use of virtual reality exposure therapy in anxiety disorders and posttraumatic stress disorder. There is hardly any evidence that virtual reality therapy is effective in generalized anxiety disorder and obsessive-compulsive disorder. There is increasing evidence that cue exposure therapy is effective in addiction and eating disorders. Studies into the use of virtual reality therapy in psychosis, autism spectrum disorder, and attention deficit hyperactivity disorder (ADHD) are promising.

ABSTRACT

PURPOSE OF REVIEW: This review provides an overview of current methods and important aspects to consider when applying virtual worlds in the treatment of social anxiety disorder (SAD). RECENT FINDINGS: Different aspects such as dialogs between avatars and patients have been investigated as well as virtual audiences, emotional facial expression, and verbal interaction with avatars. Results of these studies are promising. Few randomized controlled trials (RCTs) have investigated the efficacy of virtual reality exposure therapy (VRET) in SAD. Unfortunately, most RCTs into the efficacy of VRET in comparison with exposure in vivo in SAD have been conducted with a combination of cognitive interventions and VRET. No differences between these conditions were found, but the pure effect of VRET as a stand-alone treatment has only been investigated in one RCT, wherein VRET was not superior to exposure in vivo. Current research into different facets of SAD and VRET has produced promising results with respect to technological aspects. No differences in efficacy between cognitive behavior therapy and VRET were found, but there is a clear need for studies investigating the efficacy of VRET as a stand-alone treatment and the therapeutic processes involved before this therapy can be disseminated in routine clinical practice.

ABSTRACT

In virtual reality exposure therapy (VRET), patients are exposed to virtual environments that resemble feared real-life situations. The aim of the current study was to assess the extent to which VRET gains can be observed in real-life situations. We conducted a meta-analysis of clinical trials applying VRET to specific phobias and measuring treatment outcome by means of behavioral laboratory tests or recordings of behavioral activities in real-life. Data sources were searches of databases (Medline, PsycInfo, and Cochrane). We included in total 14 clinical trials on specific phobias. Results revealed that patients undergoing VRET did significantly better on behavioral assessments following treatment than before treatment, with an aggregated uncontrolled effect size of g = 1.23. Furthermore, patients undergoing VRET performed better on behavioral assessments at post-treatment than patients on wait-list (g = 1.41). Additionally, results of behavioral assessment at post-treatment and at follow-up revealed no significant differences between VRET and exposure in vivo (g = -0.09 and 0.53, respectively). Finally, behavioral measurement effect sizes were similar to those calculated from self-report measures. The findings demonstrate that VRET can produce significant behavior change in real-life situations and support its application in treating specific phobias.

ABSTRACT

In this study the effects of virtual reality exposure therapy (VRET) were investigated in patients with panic disorder and agoraphobia. The level of presence in VRET was compared between using either a head-mounted display (HMD) or a computer automatic virtual environment (CAVE). Results indicate that there was no relationship between the level of experienced presence and treatment outcome. Analyses indicate that VRET in general was more effective than no treatment. No differences in effectiveness were found between VRET using an HMD or CAVE.

ABSTRACT

In recent years, virtual reality exposure therapy (VRET) has become an interesting alternative for the treatment of anxiety disorders. Research has focused on the efficacy of VRET in treating anxiety disorders: phobias, panic disorder, and posttraumatic stress disorder. In this systematic review, strict methodological criteria are used to give an overview of the controlled trials regarding the efficacy of VRET in patients with anxiety disorders. Furthermore, research into process variables such as the therapeutic alliance and cognitions and enhancement of therapy effects through cognitive enhancers is discussed. The implications for implementation into clinical practice are considered.
