abstract = {The first objective of this study was to test the convergent and discriminant validity between the “eLoriCorps Immersive Body Rating Scale” and the traditional paper-based figure rating scale (FRS). The second objective was to explore the contribution of the egocentric virtual reality (VR) perspective of eLoriCorps to understanding body image disturbances (BIDs). The sample consisted of 53 female and 13 male adults. Body size dissatisfaction, body size distortion, perceived body size, and ideal body size were assessed. Overall, outcomes showed good agreement between allocentric perspectives as measured via VR and the FRS. The egocentric VR perspective produced different results compared to both the allocentric VR perspective and the FRS. This difference revealed discriminant validity and suggested that eLoricorps’ egocentric VR perspective might assess something different from the traditional conception of body dissatisfaction, which an allocentric VR perspective generally assesses. Finally, the egocentric VR perspective in assessing BIDs deserves to be studied more extensively to explore the possibility of finding two types of body image distortion: (a) an egocentric perceptual body distortion, referring to internal body sensation affected by intra-individual changes, and (b) an allocentric perceptual body distortion, referring to external body benchmarks constructed by inter-individual comparison occurring in a given cultural context. © 2020 by the authors.

Twenty-two occasional drinkers and eighteen heavy drinkers were recruited and immersed in a virtual bar, including alcoholic beverages. After the exposure, heavy drinkers reported a significantly higher craving than occasional drinkers. Post-immersion alcohol craving was significantly related to the levels of perceived ecological validity of the virtual environment. Finally, a moderation analysis suggested that the levels of craving more strongly increased with perceived ecological validity in heavy drinkers than in occasional drinkers.

abstract = {The aim of this study is to assess if changes in dysfunctional beliefs and self-efficacy precede changes in panic apprehension in the treatment of panic disorder with agoraphobia. Subjects participated in a larger study comparing the effectiveness of cognitive restructuring and exposure. Four variables were measured: (a) the strength of each subject's main belief toward the consequence of a panic attack; (b) perceived self-efficacy to control a panic attack in the presence of panicogenic body sensations; (c) perceived self-efficacy to control a panic attack in the presence of panicogenic thoughts; and (d) the level of panic apprehension of a panic attack. Variables were recorded daily on a "0" to "100" scale using category partitioning. Multivariate time series analysis and "causality testing" showed that, for all participants, cognitive changes preceded changes in the level of panic apprehension. Important individual differences were observed in the contribution of each variable to the prediction of change in panic apprehension. Changes in apprehension were preceded by changes in belief in three cases, by changes in self-efficacy in six cases, and by changes in both belief and self-efficacy in the remaining three cases. This pattern was observed in participants in the exposure condition as well as those in the cognitive restructuring condition. These results provide more empirical support to the hypothesis that cognitive changes precede improvement. They also underlie the importance of individual differences in the process of change. Finally, this study does not support the hypothesis that exposure and cognitive restructuring operate through different mechanisms, namely a behavioral one and a cognitive one. © 2006 Elsevier Ltd.
