Evidence is growing that two modalities of computer-based exposure therapies—virtual reality and computer-aided psychotherapy—are effective in treating anxiety disorders, including fear of flying. However, they have not yet been directly compared. The aim of this study was to analyze the efficacy of three computer-based exposure treatments for fear of flying: virtual reality exposure therapy (VRET), computer-aided exposure with a therapist’s (CAE-T) assistance throughout exposure sessions, and self-administered computer-aided exposure (CAE-SA). A total of 60 participants with flying phobia were randomly assigned to VRET, CAE-T, or CAE-SA. Results indicate that the three interventions were effective in reducing fear of flying at posttreatment and at 1-year follow-up; furthermore, there were no significant differences between them in any of the outcome measure. Large within-group effect sizes were found for all three treatment conditions at both posttreatment and at follow-up. The results suggest that therapist involvement might be minimized during computer-based treatments and that CAE can be as effective as VRET in reducing fear of flying.

Attentional network functioning in emotionally neutral conditions and self-reported attentional control (AC) were analysed as predictors of the tendency to engage in dysfunctional emotion regulation strategies. Diminished attentional orienting predicted an increased tendency to engage in brooding rumination, and enhanced alertness predicted a greater chance of suppression, beyond trait anxiety and self-reported AC, which were not predictive of either rumination or suppression. This is the first study to show that some forms of dysfunctional emotion regulation are related to the attentional network functioning in emotionally neutral conditions. Results are discussed in relation to regulatory temperament and anxiety-related attentional biases literature.
