AUGMENTED REALITY Case Study
AUGMENTED REALITY • CASE STUDY • Exposure treatment: One hour. • The patient interacted with the cockroach in the container, and also with the cockroach outside the container. • The patient killed four cockraches.
AUGMENTED REALITY • Treatment outcomes were maintained at one-month follow-up. • Reports of high Reality judgment and Presence.
AUGMENTED REALITY Case Series Study • Participants: 10 patients so far (9 women and 1 man) • Four with spider phobia • Six with cockroach phobia Treatment: Adaptation of the one-session exposure program developed by Öst delivered with Augmented Reality.
AUGMENTED REALITY Results: BAT (0-12)
AUGMENTED REALITY Results: Self-report (0-126)
AUGMENTED REALITY Preference: IN VIVO vs AR (0-7)
AUGMENTED REALITY Satisfaction (0-10)
AUGMENTED REALITY Conclusions • AR: Efficacious in the treatment of specific phobia. • Significant reduction in objective and subjective measures of fear and avoidance. • Patients preferred AR rather than in vivo exposure. • Patients were satisfied with the treatment.

Controlled Studies: n > 8 Social Phobia
Social Phobia(Klinger, Bouchard et al., 2004) N = 36, 12 sessions. CBT in group.
SOCIAL PHOBIA (Klinger et al., 2005) • Sample Population = 18 participants • 10 females and 8 males • Mean age: 30.5 ± 5.06 • On average, participants have been suffering from social phobia for 14.5 years • 9 participants were also displayed symptoms of major depression (all information based only on the VRT group)
SOCIAL PHOBIA (Klinger et al., 2005) • Measures • The Short Beck Depression Inventory (BDI-13) • The Liebowitz Social Anxiety Scale (LSAS) • The Rathus Assertiveness Schedule • The Zigmond and Snaith Hospital Anxiety Depression Scale (HAD)
SOCIAL PHOBIA (Klinger et al., 2005) • Protocol – for VRT only • Overview • 12 sessions of VRT • 45 minutes each • Exposed to virtual environments for either assessment or therapy • Virtual exposure lasts less than 20 minutes per session
SOCIAL PHOBIA (Klinger et al., 2005) • Protocol (cont’d) • Virtual environments included 4 situations that social phobic patients felt were the most threatening: • Performance • Intimacy • Scrutiny • Assertiveness
SOCIAL PHOBIA (Klinger et al., 2005) • Protocol (cont’d) • Session 1 • Therapist presents virtual world to patient • Patient familiarizes the virtual world and tools in a neutral environment • Session 2-9 • 2 sessions devoted to each of the 4 virtual environments • Assessment, expose patient to VR environment, 2 phases of “therapy” exposure to the environment
SOCIAL PHOBIA (Klinger et al., 2005) • Protocol (cont’d) • Session 10-12 • 3 sessions devoted to more focused and detailed work on one or two of the four environments that gave the patient the most trouble • 12th session = conclusion to therapy and introduction of a personal program to carry out beyond the therapy
SOCIAL PHOBIA (Klinger et al., 2005)
SOCIAL PHOBIA (Klinger et al., 2005) • Conclusion: • Based on the LSAS, VRT would illustrate a better form of treatment over CBT • The differences between the two groups, however, are not significant • For VRT to be significantly better than CBT in terms of social phobia symptoms, experiment participants would have to be increased to 200-300 • Participants should be increased to a sample of 3,000 in order to find a significant difference in performance anxiety • In order to further confirm the efficacy of virtual reality for the treatment of social phobia, additional outcome studies could be conducted with the inclusion of a third control condition such as a placebo or a waiting list
