A Neuro-Technological Intervention for Adolescents With Generalised Anxiety Disorder (GAD): A Feasibility Trial

Intervention / Treatment
Detailed Description
This study is a single-arm open-label test of feasibility. The recruitment target is 30. Outpatient adolescents diagnosed with GAD will be recruited to undergo 8 x 30 minutes intervention sessions over 4 weeks. Participants who are enrolled will continue to receive treatment-as-usual prescribed by their treating psychiatrist, except for the use of psychotropics. This population is selected as they could elucidate whether our intervention can be beneficial as an early intervention program for GAD.
During the 8 bi-weekly intervention sessions, participants will don a head-mounted VR display set and a mobile EEG-biosensor. The hardwares are non-invasive.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: Neuro-Technological Intervention
Participants will attend a total of 8 x 30 minutes intervention sessions (twice a week) for four consecutive weeks, starting within 1 week after baseline assessment. Participants will also be required to fill up some questionnaires at baseline and post-intervention visits. |
During the intervention sessions, participants will don a head-mounted VR display set and a mobile EEG-biosensor.
Each session will begin with a brief audio-guided mindfulness practice, follow by a 15 minutes VR game.
Game performances will be influenced by individual's level of anxiety arousal and ability to regulate it.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Usability Questionnaire
Time Frame: Week 4
|
Usability questionnaire measures participants' experience with the neuro-technological intervention devices and software.
Subscale with12 items asking about overall comfort and usability are included, with scale range of 1 to 4 (1 - very false for me, 2 - False, 3 - True, 4 - Very true for me).
Subsequent 27-items subscale measures participants' experience with the software/virtual reality experience, with scale ranging from 1 to 7 (the lower the rating, the poorer the experience).
Total score will be obtained from summing up the scores for each subscale.
Higher score means better overall experience with the intervention.

Measure Description |
Time Frame |
---|---|---|
Multidimensional Anxiety Scale for Children (Parent-reported); 2nd Edition
Time Frame: Week 0, 5
|
The MASC is a comprehensive, multi-rater assessment of anxiety dimensions in children and adolescents aged 8 to 19 years old.
The MASC includes subscales scores for separation anxiety/phobias, GAD index, social anxiety, obsessions & compulsions, physical symptoms and harm avoidance.
Raw scores from these subscales will be summed up to obtain the total score.
Scale ranges from 0 to 3 (0 - Never, 1 - Rarely, 2 - Sometimes, 3 - Often).
Higher raw scores indicate higher anxiety symptoms.
