“…18,19 Previous studies have suggested that VR can be effective in clinical treatment. [20][21][22][23][24] One of the main advantages of a virtual environment (VE) for clinical psychologists is that it can be used in a medical facility, thus avoiding the need to venture into public situations. In fact, in most of the previous studies, VEs were used in order to simulate the real world.…”

The main goal of this paper is a preliminary evaluation of the efficacy of a virtual reality VR-based multidimensional approach to the treatment of body image attitudes and related constructs. The female obese patients (n = 28) involved in a residential weight control treatment, including low-calorie diet (1,200 kcal/day) and physical training, were randomly assigned either to the VR treatment or to psychonutritional groups based on the cognitive-behavior approach. Patients were administered a battery of outcome measures assessing eating disorders symptomatology, attitudes toward food, body dissatisfaction, level of anxiety, motivation for change, level of assertiveness, and general psychiatric symptoms. In the short-term, the VR treatment was more effective than the traditional cognitive-behavioral psychonutritional groups in improving the overall psychological state of the patients. In particular, it was more effective in improving body satisfaction, self-efficacy, and motivation for change. The improvement was associated with a reduction in problematic eating and social behaviors. The possibility of inducing a significant change in body image and its associated behaviors using a VR-based short-term therapy can improve body satisfaction in traditional weight reduction programs. However, given that this research that does not include a follow-up study, the obtained results are preliminary.

“…To date, VR technology is most commonly used to treat phobias and other anxiety disorders. The use of VR as a new form of exposure therapy was first proposed in the 1990s when VR scenarios were used to create exposure activities for individuals with acrophobia (Hodges, Bolter, Mynatt, Ribarsky, & Van Teylingen, 1993; Hodges et al, 1995). Although the majority of research has focused on the use of VR as a tool in exposure therapy for phobias and, in some cases, posttraumatic stress disorder (PTSD), other studies have examined the effectiveness of VR use in other treatment modalities and for use in treatment of other disorders.…”

Virtual reality (VR) models allow investigators to explore high-risk situations carefully in the laboratory using physiological assessment strategies and controlled conditions not available in field settings. This article introduces the use of a virtual experience to examine the influence of self-regulatory skills training on female participants' reactions to a high-risk encounter with an aggressive male. Sixty-three female participants were recruited for the study. Demographic data indicated that 54% of the participants were not currently in a relationship, 36.5% were in a committed relationship, and 9.5% were occasionally dating. After obtaining informed consent, participants were assigned randomly to either a diaphragmatic breathing training condition or an attention control condition. Results indicated that both groups rated the virtual environment as equally realistic; the aggressive advances of the male were also perceived as equally real across the two experimental groups. Physiological data indicated that there were no differences between the groups on respiration or cardiovascular measures during baseline or during the VR task. After the VR experience, however, the participants in the breathing training condition had lower respiration rates and higher heart rate variability measures than those in the control condition. The results suggest that VR platforms provide a realistic and challenging environment to examine how self-regulation procedures may influence behavioral outcomes. Real-time dynamic engagement in a virtual setting affords investigators with an opportunity to evaluate the utility of self-regulatory skills training for improving safety in situations where there are uncertain and risky outcomes.

Virtual reality is a technology, a communication interface, and an artificial experience. These facets are the foundations of a new clinical environment that can be used for integrating and enhancing actual therapeutic approaches. For this reason, virtual reality is starting to play an important role in clinical psychology-as shown by its use in the treatment of phobias, eating disorders and obesity, male erectile dysfunctions, and posttraumatic stress disorders-that is expected to increase in the next years. This article presents the possible role of virtual environments in clinical psychology, discussing their clinical rationale. Finally, it describes the technological tools and safety requirements associated with the use of this approach. People perceive external reality through the five senses of sight, hearing, touch, taste, and smell. If any one of these sensory inputs is re
