RecruitingPhase 4Behavioural interventionR61/33 - VR Study Phase 4The goal of this larger parallel group randomized trial is to test the impact of a virtual reality program for improving the ability of emerging adults (age 18-25) with attention deficit hyperactivity disorder (ADHD) to stay focused while completing homework and studying. This study compares the impact of using a virtual reality headset to using a virtual reality headset while also receiving feedback about levels of focus to a control group. The main question is whether participants demonstrate significantly improved concentration while completing homework and studying in virtual reality and whether they enjoy and prefer working in a virtual reality environment. Concentration is measured both through participant report and also using keyboard and mouse click data to assess work productivity objectively.
