Behavioral therapy combined with a virtual reality exposure (VRE) component can be useful for the treatment of fears and phobias. This study aimed to: (a) describe and evaluate a behavioral therapy procedure amplified by VRE for the treatment of fear of height and (b) record sense of presence and cybersickness during exposure to assess the Virtua Therapy simulator. The procedure consisted of: an initial session; six therapy sessions, which included graduate exposure, prevention of escape-avoidance responses, and functional analyses of behaviors; two follow-up sessions. Sense of presence and cybersickness were recorded. The intervention decreased the participants’ levels of anxiety and the frequency of avoidance of situations involving heights in the virtual environment, and they reported decreases in day-to-day avoidance responses, demonstrating therapeutic effects. The simulator produced sense of presence. Cybersickness occurred primarily during the first session, indicating habituation effect. It was concluded that the Virtua Therapy simulator is an appropriate device for behavioral therapy.Downloads

Pre-Print, Accepted Manuscript, and Final Published Version Archiving, Sharing and Re-Use Policy
The authors’ contribution to RBTCC has three versions, which are defined below and can be archived, shared, and re-used under the following conditions:
1. A pre-print (or original submission) is the author’s version of the article before peer-review has taken place. Prior to acceptance for publication, author(s) retain the right to make a Pre-Print of their article available: on their own personal, self-maintained website; or on a legally compliant pre-print server (e.g., PsyArXiv, arXiv). Once the article has been published, the author(s) should update their acknowledgement and provide a link to the definitive version on RBTCC’s website, adding a text such as: “This is a pre-print of an article published in the Brazilian Journal of Behavioral and Cognitive Therapy. The final authenticated version is available online at: https://doi.org/[insert DOI]”. RBTCC encourages posting of preprints of manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration from RBTCC. Authors should disclose details of preprint posting - including DOI and licensing terms - upon submission of the manuscript or at any other point during consideration at RBTCC publication process.
2. An accepted manuscript is the version accepted for publication in RBTCC following peer review but prior to copyediting and typesetting that can be made available under the following conditions:
(i) on their own personal, self-maintained website immediately on acceptance,
(ii) for public release, 12 months after first publication (i.e., "Embargo Period"), on any of the following: their employer’s internal website; their institutional and/or funder repositories. Accepted manuscripts may also be deposited in such repositories immediately on acceptance, provided that they are not made publicly available until after the Embargo Period.
An acknowledgement in the following form should be included with a link to the published version on the publisher’s website: “This is a post-peer-review, pre-copyedit version of an article published in the Brazilian Journal of Behavioral and Cognitive Therapy. The final authenticated version is available online at: http://dx.doi.org/[insert DOI]”.
3. The final published (PDF) version is the copy-edited and typeset RBTCC’s PDF, the same version published on the journal’s website. It can be archived in institutional or funder repositories and can be made publicly accessible immediately.
Any re-use terms for users of websites and repositories (where your pre-print or accepted manuscript are posted) are restricted to non-commercial and no derivative uses.
The authors may not republish or translate any version of their contribution in another journal without prior permission from RBTCC’s Editor-in-Chief.
