• Augmented Reality (AR) is helpful for overcoming the challenges of in vivo exposure therapy for Specific Phobia (SP). Specifically, Projection-based AR exposure therapy (P-ARET) allows the individual to face the feared animal without intrusive hardware, the phobic stimulus can be controlled, and it can maximize “variability”, producing a positive effect in the generalization of the results. The goal of this work is to assess the feasibility of P-ARET for SP, comparing multiple stimuli (MS) versus single stimulus (SS) conditions and evaluating the participants’ user experience. Adherence to a daily monitoring app (Emotional Monitor) and preliminary efficacy of the P-ARET treatment were assessed. Four participants diagnosed with SP of cockroaches (DSM-5) were randomly assigned to different baselines. Episodic and daily evaluations were performed. Participants considered the MS condition more aversive but more effective than the SS condition. Adherence to the mobile app was 83% for three participants and 55% for the remaining person. Analyses of non-overlap of all pairs and changes in the functionality levels showed a decrease in the SP symptoms at post-treatment and follow-ups. This study offers preliminary feasibility results for a novel form of P-ARET to treat participants with cockroach phobia, which may also apply to other phobias.
