efficacy of an internet based Exposure Treatment for flying phobia no fear airlines with and without therapist guidance a randomized controlled trial
BMC Psychiatry, 2019Co-Authors: Daniel Campos, Claude Botella, Adriana Mira, Diana Castilla, Juana BretonlopezAbstract:Internet-based Treatments appear to be a promising way to enhance the in vivo Exposure approach, specifically in terms of acceptability and access to Treatment. However, the literature on specific phobias is scarce, and, as far as we know, there are no studies on Flying Phobia (FP). This study aims to investigate the effectiveness of an Internet-based Exposure Treatment for FP (NO-FEAR Airlines) that includes Exposure scenarios composed of images and sounds, versus a waiting-list control group. A secondary aim is to explore two ways of delivering NO-FEAR Airlines, with and without therapist guidance. A randomized controlled trial (RCT) was conducted in which 69 participants were allocated to: 1) NO-FEAR Airlines totally self-applied, 2) NO-FEAR Airlines with therapist guidance, 3) a waiting-list control group. Primary outcome measures were the Fear of Flying Questionnaire-II and the Fear of Flying Scale. Secondary outcomes included the Fear and Avoidance Scales, Clinician Severity Scale, and Patient’s Improvement scale. Behavioral outcomes (post-Treatment flights and safety behaviors) were also included. Mixed-model analyses with no ad hoc imputations were conducted for primary and secondary outcome measures. NO-FEAR Airlines (with and without therapist guidance) was significantly effective, compared to the waiting list control group, on all primary and secondary outcomes (all ps < .05), and no significant differences were found between the two ways of delivering the intervention. Significant improvements on diagnostic status and reliable change indexes were also found in both Treatment groups at post-Treatment. Regarding behavioral outcomes, significant differences in safety behaviors were found at post-Treatment, compared to the waiting list. Treatment gains were maintained at 3- and 12-month follow-ups. FP can be treated effectively via the Internet. NO-FEAR Airlines helps to enhance the Exposure technique and provide access to evidence-based psychological Treatment to more people in need. These data are congruent with previous studies highlighting the usefulness of computer-assisted Exposure programs for FP, and they contribute to the literature on Internet-based interventions. To the best of our knowledge, this is the first RCT to investigate the effectiveness of an Internet-based Treatment for FP and explore two ways of delivering the intervention (with and without therapist guidance).

the acceptability of an internet based Exposure Treatment for flying phobia with and without therapist guidance patients expectations satisfaction Treatment preferences and usability
Neuropsychiatric Disease and Treatment, 2018Co-Authors: Daniel Campos, Claude Botella, Adriana Mira, Diana Castilla, Juana Bretonlopez, Rosa María Baños, Soledad QueroAbstract:Purpose: Internet-based Treatments have been tested for several psychological disorders. However, few studies have directly assessed the acceptability of these self-applied interventions in terms of expectations, satisfaction, Treatment preferences, and usability. Moreover, no studies provide this type of data on Internet-based Treatment for flying phobia (FP), with or without therapist guidance. The aim of this study was to analyze the acceptability of an Internet-based Treatment for FP (NO-FEAR Airlines) that includes Exposure scenarios composed of images and real sounds. A secondary aim was to compare patients' acceptance of two ways of delivering this Treatment (with or without therapist guidance). Patients and methods: The sample included 46 participants from a randomized controlled trial who had received the self-applied intervention with (n = 23) or without (n = 23) therapist guidance. All participants completed an assessment protocol conducted online and by telephone at both pre- and postTreatment. Results: Results showed good expectations, satisfaction, opinion, and usability, regardless of the presence of therapist guidance, including low aversiveness levels from before to after the intervention. However, participants generally preferred the therapist-supported condition. Conclusion: NO-FEAR Airlines is a well-accepted Internet-based Treatment that can help enhance the application of the Exposure technique, improving patient acceptance and access to FP Treatment.

treating cockroach phobia using a serious game on a mobile phone and augmented reality Exposure a single case study
Computers in Human Behavior, 2011Co-Authors: Cristina Botella, Soledad Quero, Juana Bretonlopez, Rosa M Banos, Azucena Garciapalacios, Irene Zaragoza, Mariano AlcanizAbstract:In vivo Exposure has proved its efficacy in the Treatment of specific phobias; however, not all patients benefit from it. Communication and information technologies such as Virtual Reality (VR) and Augmented Reality (AR) have improved Exposure Treatment adherence and acceptance. Serious games (SG) could also be used in order to facilitate Exposure Treatment. A line of research on SG is emerging which focuses on health issues. We have developed a SG for the Treatment of cockroach phobia that uses a mobile phone as the application device. This work examines results of an N=1 study about whether the use of this mobile game can facilitate Treatment of this specific phobia preparing her for the AR Exposure. A 25-year-old woman with cockroach phobia participated in the study. Results showed that the use of the mobile game reduced her level of fear and avoidance before a ''one-session'' AR Exposure Treatment was applied, following the guidelines by Ost. The participant found very helpful the use of the SG before the AR Exposure session and she was willing to use it after the AR Exposure session as a homework assignment. Although the results of this study are preliminary, SG appears to be a line of research of high interest in clinical psychology for the Treatment of specific phobias.

and yet they correlate psychophysiological activation predicts self report outcomes of Exposure therapy in claustrophobia
Journal of Anxiety Disorders, 2008Co-Authors: Georg W Alpers, Roxane SellAbstract:Abstract The study examines whether self-reported fear and physiological activation are concordant when claustrophobic patients are exposed to small spaces, whether the measures change in synchrony for individual patients and whether initial activation of measures can predict the outcome of an Exposure Treatment. Ten patients with claustrophobia participated in six in-vivo Exposure sessions with continuous monitoring of self-reported fear and their EKG. Partial pressure of carbon dioxide ( p CO 2 ), a measure of hyperventilation, was available in a subsample of patients. While evidence for concordance of self-reported fear and heart rate was limited, the measures changed synchronously within subjects. Most importantly, higher heart rate at the beginning of the first Exposure session predicted better Treatment outcome. Because self-reported fear turned out not to be a reliable predictor of the outcome, this is interpreted as evidence for the incremental validity of physiological measures of fear.

virtual reality Exposure therapy
The journal of psychotherapy practice and research, 2010Co-Authors: Barbara Olasov Rothbaum, Larry F Hodges, Rob KooperAbstract:It has been proposed that virtual reality (VR) Exposure may be an alternative to standard in vivo Exposure. Virtual reality integrates real-time computer graphics, body tracking devices, visual displays, and other sensory input devices to immerse a participant in a computer- generated virtual environment. Virtual reality Exposure is potentially an efficient and cost-effective Treatment of anxiety disorders. VR Exposure therapy reduced the fear of heights in the first controlled study of virtual reality in Treatment of a psychiatric disorder. A case study supported the efficacy of VR Exposure therapy for the fear of flying. The potential for virtual reality Exposure Treatment for these and other disorders is explored, and therapeutic issues surrounding the delivery of VR Exposure are discussed.

virtual reality Exposure therapy for ptsd vietnam veterans a case study
Journal of Traumatic Stress, 1999Co-Authors: Barbara Olasov Rothbaum, Larry F Hodges, Renato D Alarcon, David J Ready, Fran Shahar, Ken Graap, Jarrel Pair, Philip Hebert, Dave Gotz, Brian WillsAbstract:Virtual reality (VR) integrates real-time computer graphics, body tracking devices, visual displays, and other sensory input devices to immerse a participant in a computer-generated virtual environment that changes in a natural way with head and body motion. VR Exposure (VRE) is proposed as an alternative to typical imaginal Exposure Treatment for Vietnam combat veterans with posttraumatic stress disorder (PTSD). This report presents the results of the first Vietnam combat veteran with PTSD to have been treated with VRE. The patient was exposed to two virtual environments, a virtual Huey helicopter flying over a virtual Vietnam and a clearing surrounded by jungle. The patient experienced a 34% decrease on clinician-rated PTSD and a 45% decrease on self-rated PTSD. Treatment gains were maintained at 6-month follow-up.

effectiveness of computer generated virtual reality graded Exposure in the Treatment of acrophobia
American Journal of Psychiatry, 1995Co-Authors: Barbara Olasov Rothbaum, Dan Opdyke, Rob Kooper, Larry F Hodges, James S. WillifordAbstract:Objective: The authors' goal was to examine the efficacy of computer-generated (virtual reality) graded Exposure in the Treatment of acrophobia (fear of heights). Method: Twenty college students with acrophobia were randomly assigned to virtual reality graded Exposure Treatment (N=12) or to a waiting-list comparison group (N=8). Seventeen students completed the study. Sessions were conducted individually over 8 weeks. Outcome was assessed by using measures of anxiety, avoidance, attitudes, and distress associated with Exposure to heights before and after Treatment. Results: Significant differences between the students who completed the virtual reality Treatment (N=10) and those on the waiting list (N=7) were found on all measures. The Treatment group was significantly improved after 8 weeks, but the comparison group was unchanged. Conclusions: The authors conclude that Treatment with virtual reality graded Exposure was successful in reducing fear of heights

diaphragmatic breathing during virtual reality Exposure therapy for aviophobia functional coping strategy or avoidance behavior a pilot study
BMC Psychiatry, 2017Co-Authors: Youssef Shiban, Julia Diemer, Jana Muller, Johanna Bruttingschick, Paul Pauli, Andreas MuhlbergerAbstract:Although there is solid evidence for the efficacy of in vivo and virtual reality (VR) Exposure therapy for a specific phobia, there is a significant debate over whether techniques promoting distraction or relaxation have impairing or enhancing effects on Treatment outcome. In the present pilot study, we investigated the effect of diaphragmatic breathing (DB) as a relaxation technique during VR Exposure Treatment. Twenty-nine patients with aviophobia were randomly assigned to VR Exposure Treatment either with or without diaphragmatic breathing (six cycles per minute). Subjective fear ratings, heart rate and skin conductance were assessed as indicators of fear during both the Exposure and the test session one week later. The group that experienced VR Exposure combined with diaphragmatic breathing showed a higher tendency to effectively overcome the fear of flying. Psychophysiological measures of fear decreased and self-efficacy increased in both groups with no significant difference between the groups. Our findings indicate that diaphragmatic breathing during VR Exposure does not interfere with the Treatment outcome and may even enhance Treatment effects of VR Exposure therapy for aviophobic patients.

effect of combined multiple contexts and multiple stimuli Exposure in spider phobia a randomized clinical trial in virtual reality
Behaviour Research and Therapy, 2015Co-Authors: Youssef Shiban, Paul Pauli, Iris Schelhorn, Andreas MuhlbergerAbstract:Abstract Background Our previous study indicated that Treatment in multiple contexts (MC) improved the outcome of Exposure Treatment by reducing return of fear. This effect was evident when the test was conducted immediately post Treatment. In the present study, we conducted a Treatment analogue study where we investigated whether an Exposure to multiple stimuli (MS) and a combination of both MS and MC would further improve Treatment efficacy in the short and long terms. Method Spider-phobic patients (N = 58) were randomly allocated to one of four groups. Each group received virtual reality (VR) Exposure Treatment in either one or four different contexts and was exposed to either one or four different spiders. All participants completed both a VR test with a novel spider in a novel context and an in vivo behavioral avoidance test (BAT) pre-, post-Treatment and at follow-up. Results Short-term but not long-term return of fear was attenuated by multiple context Exposure in VR. Long-term effect of fear attenuation was observed only in the MS single context group. In the BAT, the multiple stimuli condition seemed to be more beneficial in both the short and long term. Notably, there was no evidence for superiority of the combined multiple stimuli and contexts condition. Conclusion Change of contexts during Exposure significantly reduced return of fear post Treatment; however, similar results could not be observed with a follow-up test. The implementation of multiple stimuli during Exposure seems to have both short-term and long-lasting beneficial effects on the Treatment outcome. We recommend further investigation of this phenomenon and introduce further possible improvements to our paradigm.
