An interventional study of Exposure intervention using 360 degree videos in Social Anxiety Disorder and Agoraphobia, sponsored by University of Liege. Status unknown at 1 site in Belgium. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2021-10-05.
Sponsored by University of Liege · Not applicable, Interventional, and Treatment
This study aims to test the feasibility and efficacy of an individualized exposure intervention using 360-degree videos for social anxiety and agoraphobia. A multiple single case design is followed with a pre-post-follow up assessment and multiple baselines. In addition, an experience sampling method is used to explore the role of dysfunctional beliefs and self-efficacy in the efficacy intervention.
There is growing evidence that supports the use of Virtual Reality (VR) to address anxiety disorders such as social anxiety and agoraphobia. The main advantage of VR is to expose participants to their fears in a controlled and safe environment. However, the access to VR remains costly for health professionals who need to pay licenses for the use of a limited number of environments. Therefore, these standardized environments only address the symptoms of standard anxious patients. As a way to provide an accessible tool that can be tailored according to patients' specific difficulties, the proposed approach builds on 360-degree videos as an alternative to VR.
The aim of the present study is to test the feasibility and efficacy of an individualized expo-sure intervention using 360-degree videos. In addition, the role of cognitive processes (i.e., dysfunctional beliefs and self-efficacy) in the exposure efficacy is examined. The intervention includes eleven sessions including five sessions of exposure in 360-degree videos de-signed especially for each patient difficulties.
A multiple single-case design (n=5) is adopted with three types of evaluations: (1) traditional assessment scale of primary/secondary outcomes and aspects related to the therapy, (2) daily ambulatory assessment with a multiple baseline design, (3) experience sampling of cognitive processes about feared situations.
Each video will also be assessed by the participants after exposure sessions.

Social anxiety: avoidance
The French version of the LSAS-SR was used to assess the levels of anxiety and avoidance associated with social situations. The LSAS-SR consists of 24 items describing four types of situations: (1) social interactions, (2) public speaking, (3) eating and drinking in public, (4) being observed. Each item is rated on a 3-point scale according to both the level of fear (0 = "no fear" to 3 = "severe") and the level of avoidance (0 = "never" to 3 = "Usually"). A general total score can be obtained by summing all items and specific score of avoidance and fear as well as scores for specific type of situations can be obtained by summing specific items.
Time frame: Baseline : up to 4 weeks before intervention

Self-efficacy toward managing the situation, the occurrence of the feared outcome and the fear itself
A non-validated French version of the ACQ-R was used to assess the participants' perception of control over anxiety and anxiety-related situations (i.e. similar to self-efficacy). The ACQ-R is a 15-items scale assessing the perceived control of (1) emotion (5 items; e.g., "I am able to control my level of anxiety"), (2) threats (6 items; e.g., "There is little I can do to change frightening events") and (3) stress (4 items; e.g., "When I a put under stress, I am likely to lose control").

Dysfunctional beliefs
A non-validated French version of the AABS-2 was used to assess dysfunctional beliefs known to be aetiologically related to anxiety. The AABS-2 consists of 33 beliefs concerning (1) Exposure to judgement, (2) Body vigilance, (3) Thought manifestations and (4) Anxiety. Items are rated on a 7-point Likert scale ranging from 0 to 100 with anchor points at 20, 40, 50, 60, 80%. The four specific scores and one general score are obtained by adding the relevant items. Higher scores indicate greater adherence in beliefs associated with anxiety.

Therapy outcome
The French version of the outcome Questionnaire was used to assess clinical changes in participants. The MI-45 consists of 45 items that assess (1) intrapsychic symptoms of distress (i.e., 25 items, symptoms of depression and anxiety) (2) interpersonal relationship, (i.e., 11 items, satisfaction and difficulties during social interactions) and (3) social roles performance (i.e., 9 items, level of dissatisfaction, conflict, distress and incompetence related to employment, family and hobbies). All items are rated on a 5-point Likert scale ranging from 0 = Never to 4 = Almost Always. The total score ranging from 0 to 80 and the three specific scores can be obtained by adding the relevant items. In addition, the scale possesses a clinical threshold of 63 and a "reliable clinical change" starting from a 17-points gain or loss.

Therapy outcome
The French version of the outcome Questionnaire was used to assess clinical changes in participants. The MI-45 consists of 45 items that assess (1) intrapsychic symptoms of distress (i.e., 25 items, symptoms of depression and anxiety) (2) interpersonal relationship, (i.e., 11 items, satisfaction and difficulties during social interactions) and (3) social roles performance (i.e., 9 items, level of dissatisfaction, conflict, distress and incompetence related to employment, family and hobbies). All items are rated on a 5-point Likert scale ranging from 0 = Never to 4 = Almost Always. The total score ranging from 0 to 80 and the three specific scores can be obtained by adding the relevant items. In addition, the scale possesses a clinical threshold of 63 and a "reliable clinical change" starting from a 17-points gain or loss.
