To examine the efficacy of a fully self-guided app-based virtual reality cognitive behavior therapy (VR CBT) using low-cost (cardboard) virtual reality goggles compared with a wait-list control group and to determine its user friendliness. We hypothesize that children with GAD enrolled in the self-guided app will present lower scores of anxiety.
A randomized controlled design will be carried out, in which the effectiveness and user- friendliness of an online app-based VR self-help treatment '0-anxiety' will be evaluated. Our primary objective is to determine the clinical effects (a reduction in anxiety symptoms at post-test [between the experimental condition and controls] of 0-anxiety, and whether effects are sustainable at follow-up [a reduction in anxiety symptoms between baseline and follow-up for those in the experimental condition]). Our secondary objective is to determine the user-friendliness of 0-anxiety. In this study, 230 children from the Brazilian population will be randomized over 2 conditions: the experimental condition (0-anxiety) and a waitlist condition. The duration of the intervention will be 3 weeks. Measures will be taken at baseline, directly after the intervention (3 weeks) and at 3 months (follow-up). All measures will be completed online. Therefore, the child will participate in the study in his/her natural environment. Subjects in the wait-list condition will receive the intervention after completion of the post-test. Randomization (block-randomization) will be performed by an independent researcher.

| Fear Survey Schedule for Children-Revised (FSSC-R) | The FSSC-R is a widely used self-report measure of children and adolescents' fears. The instrument, a revision of Scherer and Nakamura's (1968) original Fear Survey Schedule for Children, contains 80 items that are each rated on a three-point scale (none, some, a lot). A total fearfulness score can be obtained, as can five subscale scores based on a factor analysis of the items. In addition, the number of intense fears can be indicated (i.e., the number of fears endorsed 'a lot'), as can the most prevalent fears for a given child/adolescent or group of children and adolescents (i.e., boys, preadolescents, school phobic youngsters, etc.). Higher scores mean worse fear levels. |

| Spence Children's Anxiety Scale - Parent and Children version | The scale is completed by a parent of an anxious child between the ages of 6 to 18. It provides an overall measure of anxiety together with scores on six sub-scales each tapping a specific aspect of child anxiety. - Panic attack and agoraphobia - Separation anxiety - Physical injury fears - Social phobia - Obsessive compulsive - Generalized anxiety disorder / overanxious disorder. This yields a maximum possible score of 114. Higher scores mean worse anxiety levels. | baseline, 3 weeks after the intervention, and 3 months after the completion of the intervention |
