In Vivo Versus Augmented Reality Exposure for Small Animal Phobia

Summary

The aim of this study is to explore the differential efficacy of in vivo exposure versus augmented reality exposure in the treatment of specific phobia (small animals).

The hypothesis is: There will not be significant statistical differences in the efficacy of in vivo exposure therapy versus augmented reality exposure in the treatment of specific phobia (small animals).

Conditions

• Phobic Disorders

Interventions

BEHAVIORAL

In Vivo Exposure for Animal Phobia following Öst´s guidelines

In vivo exposure is applied using "one-session treatment" guidelines (Öst, Salkovskis and Hellström, 1991). Exposure is conducted in a single extended session lasting up to 3 hours and implemented individually. The treatment includes participant modelling, in vivo exposure, reinforced practice and cognitive challenge. Treatment in a single session is just a starting point; it is recommended that the participants continue to be exposed to the phobic situations after therapy in their daily lives in order to fully surmount their problems. Participants are informed that the treatment required close collaboration between themselves and the therapist. The exposure session is completed in a gradual and planned way.

BEHAVIORAL

Augmented Reality Exposure for Animal Phobia following Öst´s guidelines

Augmented Reality (AR) is a variation of Virtual Reality in which the user sees the real world augmented by various virtual elements; it complements reality rather than replacing it completely (Azuma et al., 2001). The most significant aspect of AR is that the virtual elements add relevant and helpful information to the physical information available in the real world. The system includes the options of changing the number, movement and size of small animals. Preliminary data show the utility of the system for the treatment of insect phobia (Botella et al., 2005). AR exposure is applied in the same way than in vivo exposure, that is, in a gradual, planned and controlled way using "one-session treatment" guidelines (Öst, Salkovskis and Hellström, 1991). The therapist can see what the participant sees in AR on a monitor and observe the same stimuli.
