abstract = {Aim: to assess the effectiveness of conducting exposure in virtual reality (VR) for children suffering from arachnophobia. Method: This study uses an uncontrolled group design, supported by a single-case design with multiple baselines across individuals. The sample includes nine children and young adolescents suffering from arachnophobia. Participants are randomly assigned to baselines of three different durations (three, four or five weeks) during which they only self-monitor their fear. The treatment consists of six 75-minute therapy sessions delivered according to a standardized manual. Questionnaires and brief self-reports relevant to the phobia are administered before, during and after treatment as well as at a 6-month follow-up. Results: Symptoms are significantly reduced on measures of fear and avoidance, generalization and process (dysfunctional beliefs). All gains are maintained at the 6-mo follow-up, with further improvement in children's beliefs about their own behaviour when facing spiders. All findings are backed-up by the daily self-monitoring data. Conclusion: Conducting exposure in VR represents a promising technique to treat phobias in children. Implication: The attractiveness of this new treatment tool may foster children's motivation to engage and stay in therapy. © 2007. AFTCC. Édité par Elsevier Masson SAS.},
