Background: Generalized anxiety disorder is one of the most common anxiety disorders observed in clinical centers and the general population. This study aimed to evaluate the efficacy of virtual reality-based worry exposure therapy on the Anxiety Severity and worry in patients with symptoms of generalized anxiety disorder. Materials and Methods: This study was conducted in the framework of a single-subject experimental design using Multiple baselines with a 6-week follow-up. Three women with GAD were selected through a structured clinical interview based on the criteria of Diagnostic and Statistical Manual of Mental Disorders 5 by Convenience Sampling among those who referred to the Counseling centers in Tabriz. The protocol of this study followed the manual by Becker and Margraf which describes imaginal exposure for GAD applied in 15 sessions. The only difference was that in this research exposure to virtual reality replaced with imagination. In this study, three 360-degree films were made by the researcher used for exposure. The content made in the form of 360-degree videos and displayed to patients through virtual reality tools. The scales to assess changes in Anxiety Severity and worry include The Penn State Worry Questionnaire and The Overall Anxiety Severity and Impairment Scale. Data analyzed with visuals inspection, improvement percentage, and reliable change index strategies. Results: Results showed that virtual reality-based worry exposure therapy has significant efficiency on the reduction of Anxiety Severity and worry clinically and statistically (p<0.05). Conclusion: Virtual reality-based worry exposure therapy has appropriate efficacy in reducing GAD symptom severity.

ABSTRACT Objective: The Penn State Worry Questionnaire (PSWQ) is a commonly used measure of treatment outcome for late-life generalized anxiety disorder (GAD). However, there is considerable variability in the definitions used to define treatment response and remission. This study aimed to provide empirically derived guidelines for assessing treatment response and remission among older adults with GAD using the PSWQ and the abbreviated PSWQ (PSWQ-A). Design: Longitudinal assessment of GAD symptoms pre- and posttreatment. Participants: Participants were 259 older adults aged 60–86 years with a diagnosis of GAD who were assessed before and after treatment. Intervention: Participants were randomly assigned to cognitive behavioral therapy or control (waitlist, discussion group, or supportive therapy) conditions. Measurements: Signal-detection analyses using receiver operating characteristic (ROC) methods were used to determine optimal agreement between structured diagnostic interviews and scores on the PSWQ and PSWQ-A. Results: Results suggest that a score of ≤51 was optimal for defining diagnostic remission status on the PSWQ, and a score of ≤24 was optimal on the PSWQ-A. A 9% reduction or ≥4-point reduction was optimal for assessing treatment response on the PSWQ. The PSWQ-A was poor at identifying treatment response status. Conclusions: Findings suggest that most of the previously used definitions have underestimated the treatment effects for late-life GAD. However overall, the PSWQ and PSWQ-A are suboptimal for assessing treatment outcome for late-life GAD. The standardization of response and remission criteria has implications for comparison between treatment trials, and for the benchmarking of outcomes in clinical practice.

Background: Cognitive exposure, a treatment of choice for hypothetical fears, involves listening repeatedly to a recorded scenario of one's worst hypothetical fear. A major limitation, however, is that the script cannot be easily modified. Aims: The current study assessed the feasibility of a brief guided internet-based written exposure therapy (iWET) for hypothetical fears, Mind at Peace. Method: Fifty-three adults presenting clinical levels of anxiety (GAD-7 ≥ 8) and worry (PSWQ ≥ 45) were recruited. A single group pre-test/post-test design including a 3-month follow-up was used. Mind at Peace is a 6-week iWET consisting of psychoeducation and five 30-minute weekly writing exposure sessions. Feasibility outcome measures included treatment adherence, attrition, treatment acceptability and preliminary efficacy. Primary outcome measures were the Generalized Anxiety Disorder-7 (GAD-7) and the Penn State Worry Questionnaire (PSWQ). Results: Attrition was higher (57%) and adherence lower (28%) than expected. Intent-to-treat repeated measures ANOVAs revealed significant and large improvements on the GAD-7 (ƞp2 = 0.36) and the PSWQ (ƞp2 = 0.23) with similar findings among study completers. Remission rates were higher on the GAD-7 than on the PSWQ, suggesting that Mind at Peace may primarily target general symptoms of generalized anxiety. Rates of acceptability varied, but nearly all study completers reported that they would recommend this treatment to a friend. Conclusions: This study provided valuable information on Mind at Peace. Methodological changes are proposed to improve its feasibility. A more definitive trial incorporating suggested methodological improvements is recommended.

Background: Internet-delivered cognitive behaviour therapy (iCBT) has been found to be an effective way to disseminate psychological treatment, and support given by a therapist seems to be important in order to achieve good outcomes. Little is known about what the therapists actually do when they provide support in iCBT and whether their behaviour influences treatment outcome. Aims: This study addressed the content of therapist e-mails in guided iCBT for generalized anxiety disorder. Method: We examined 490 e-mails from three therapists providing support to 44 patients who participated in a controlled trial on iCBT for generalized anxiety disorder. Results: Through content analysis of the written correspondence, eight distinguishable therapist behaviours were derived: deadline flexibility, task reinforcement, alliance bolstering, task prompting, psychoeducation, self-disclosure, self-efficacy shaping, and empathetic utterances. We found that task reinforcement, task prompting, self-efficacy shaping and empathetic utterances correlated with module completion. Deadline flexibility was negatively associated with outcome and task reinforcement positively correlated with changes on the Penn State Worry Questionnaire. Conclusions: Different types of therapist behaviours can be identified in iCBT, and though many of these behaviours are correlated to each other, different behaviours have an impact on change in symptoms and module completion.

The cognitive behavioral treatment of generalized anxiety disorder (GAD) often involves exposing patients to a catastrophic scenario depicting their most feared worry. The aim of this study was to examine whether a standardized scenario recreated in virtual reality (VR) would elicit anxiety and negative affect and how it compared to the traditional method of imagining a personalized catastrophic scenario. A sample of 28 participants were first exposed to a neutral non-catastrophic scenario and then to a personalized scenario in imagination or a standardized virtual scenario presented in a counterbalanced order. The participants completed questionnaires before and after each immersion. The results suggest that the standardized virtual scenario induced significant anxiety. No difference was found when comparing exposure to the standardized scenario in VR and exposure to the personalized scenario in imagination. These findings were specific to anxiety and not to the broader measure of negative affect. Individual differences in susceptibility to feel present in VR was a significant predictor of increase in anxiety and negative affect. Future research could use these scenarios to conduct a randomized control trial to test the efficacy and cost/benefits of using VR in the treatment of GAD.
