Design outcomes

Primary

MeasureTime frame
It is expected to find a reduction in participants' social anxiety symptoms, verified by the scores reduction in the Liebowitz Social Anxiety Scale - Self Reported Version and the Social Phobia Inventory, from a variation of at least 5% in the pre and post intervention measurements;It is expected that there will be a significant difference between the results obtained in the active group and the control group, measured by the statistic p and the cohen effect size d, with p less than or equal to 0.05 and an effect greater than or equal to 0.5 in the pre and post intervention measurements

Secondary

MeasureTime frame
A reduction in cardiac symptoms is expected during exposure to virtual reality video, as measured by heart rate variability, from at least 5% variation in pre and post-intervention measurements;An increase in participant performance during the behavioral task is expected, as measured by the performance indexes assessed by the judges and the participant, from at least 5% variation in pre and post-intervention measurements;A reduction in the anxiety level felt by the participant during the behavioral task is expected, as measured by the anxiety level self-assessment scale, from at least 5% variation in pre and post-intervention measurements;The effect is expected to last 30 days after the last intervention session, as measured by the statistics p and by the cohen effect size, with p less than or equal to 0.05 and an effect greater than or equal to 0.5 in the pre and post intervention measurements
