17 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

18   Treatment outcomes were maintained at one-month follow-up.  Reports of high Reality judgment and Presence. AUGMENTED REALITY

19 Participants: 10 patients so far (9 women and 1 man)  Four with spider phobia  Six with cockroach phobia AUGMENTED REALITY Case Series Study Treatment: Adaptation of the one-session exposure program developed by Öst delivered with Augmented Reality.

24 AUGMENTED REALITYConclusions  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.

31 Social Phobia (Klinger, Bouchard et al., 2004) N = 36, 12 sessions. CBT in group.

32 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)

33 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)

34 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)

35 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)

36 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)

37 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 12 th session = conclusion to therapy and introduction of a personal program to carry out beyond the therapy SOCIAL PHOBIA (Klinger et al., 2005)

38 SOCIAL PHOBIA (Klinger et al., 2005)

39 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 SOCIAL PHOBIA (Klinger et al., 2005)
