Virtual Reality in Rehabilitation of Executive Functions in Children With Attention Deficit Hyperactivity Disorder.

Study Overview
=================
Brief Summary
-----------------
Attention deficit hyperactivity disorder (ADHD) is caused by an abnormality in the development of the central nervous system. Children with attention and executive function difficulties often need long-lasting rehabilitation and there is an increasing need for timely, cost-effective, and feasible rehabilitation interventions, where the training is targeted to support everyday life functional capacity. The use of Virtual Reality (VR) in the rehabilitation of children with attention and executive function deficits offers opportunities to practice skills required in everyday life in environments emulating real-life situations. The major aim of this research project is to develop a novel effective VR rehabilitation method for children with deficits in attention, activity control and executive functions by using the virtual environment that corresponds to the typical everyday life. In this randomized control study VR glasses are used to present the tasks, and the levels of difficulty are adjusted according to the child's progress. Researchers expect that; 1) Intensive training improves the attention regulation, activity control skills and executive functions of the children in the intervention group; 2) Training of executive skills with motivating tasks in a virtual environment that is built to meet challenging everyday situations transfers to the child's everyday life, 3) The duration of the training effect does not depend on the success of the VR training itself, but on how well the child adopts new strategies that make everyday life easier and how the parent is able to support the child's positive behaviour in everyday life.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Epeli (Executive Performance in Everyday LIving) task | A virtual reality task for attention, executive function, and prospective memory. Change in total score, task efficacy, navigation efficacy, controller motion, and total action. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| ADHD-rating scale IV (ADHD-RS) (parent report) | The ADHD-RS (parent report) is an assessment of a child's ADHD symptoms with 18 items based on the child's behaviour over the past 6 months. 4-point Likert scale. The total score ranges 0-54, scores in inattention subscale and hyperactivity/impulsivity subscale range 0-27. Change in the total score, inattention subscale score, and hyperactivity/impulsivity subscale score on a parent-rated ADHD-RS. A lower score means a better outcome. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| Epeli Questionnaire (parent report) | An assessment of a child's functional ability and the amount of positive feedback given by the parent to the child over the past 4 weeks. 5-point Likert scale. 2 subscales: Functional ability subscale where score ranges 4-20, and Positive feedback subscale where score ranges 4-20. Change in Functional ability subscale score and Positive feedback subscale score on parent-rated Epeli- questionnaire. A higher score means a better outcome. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| Epeli Questionnaire (child report) | An assessment of a child's functional ability and the amount of positive feedback given by the parent to the child over the past 4 weeks. 5-point Likert scale. 2 subscales: Functional ability subscale where score ranges 4-20, and Positive feedback subscale where score ranges 4-20. Change in Functional ability subscale score and Positive feedback subscale score on child-rated Epeli- questionnaire. A higher score means a better outcome. | Baseline, 4-6 weeks, 6 months and 12 months. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Behavior Rating Inventory of Executive Function (BRIEF-2) (parent form) | A measure of executive functions of children and adolescents in natural settings containing 63 items rated by the parent. 3-point Likert scale. Change in Global Executive Composite score, Behavior regulation score, Emotion regulation score, and Cognitive regulation score on parent-rated BRIEF-2. In case the data in the Behavior regulation, Emotion regulation, and Cognitive regulation subscales are not too strongly correlated (r<0.7) and there will be a significant effect of the intervention on the BRIEF-2 Global Executive Composite score, we will use the subscales to conduct a post hoc analysis examining which domains of executive functions are affected. A higher score means a worse outcome. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| Behavior Rating Inventory of Executive Function (BRIEF-2) (teacher form) | A measure of executive functions of children and adolescents in natural settings containing 63 items rated by the teacher. 3-point Likert scale. Change in Global Executive Composite score, Behavior regulation score, Emotion regulation score, and Cognitive regulation score on teacher-rated BRIEF-2. In case the data in the Behavior regulation, Emotion regulation, and Cognitive regulation subscales are not too strongly correlated (r<0.7) and there will be a significant effect of the intervention on the BRIEF-2 Global Executive Composite score, we will use the subscales to conduct a post hoc analysis examining which domains of executive functions are affected. A higher score means a worse outcome. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| Concentration questionnaire (in Finnish: Keskittymiskysely) | An assessment of attention and executive function difficulties in school-aged children with 55 items. 3-point Likert Scale, Total score range 0-110. Change in Total score, Distractibility score (range 0-8), sum of Impulsivity and Motor hyperactivity subscales scores (range 0-32), sum of Directing, Sustaining and Shifting Attention subscales scores (range 0-30), and sum of Initiative, Planning, Execution and Evaluation of Action subscales scores (range 0-40) on teacher-rated Concentration questionnaire. In case the data in the Distractibility subscale, Impulsivity and Motor hyperactivity subscales, Attention subscales and Executive subscales are not too strongly correlated (r<0.7) and there will be a significant effect of the intervention on Concentration questionnaire Total score, we will use the subscales to conduct a post hoc analysis examining which domains of executive functions are affected. A higher score implies a worse outcome. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents Revised Version ( KINDL-R) (parent version) | An assessment of Health-Related Quality of Life in children and adolescents with 24 items. 5-point Likert scale. Change in Total score on parent-rated questionnaire. A higher score means a better outcome. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents Revised Version (KINDL-R) (self-report version) | An assessment of Health-Related Quality of Life in children and adolescents with 24 items. 5-point Likert scale. Change in Total score on child-rated questionnaire. A higher score means a better outcome. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| N-back test | A test for a working memory. Change in 2-back and 1-back hitrate and reaction time. | Baseline, 4-6 weeks, 6 months and 12 months. | 
| The Conners Continuous Performance Test 3rd Edition (Conners CPT3) | A computerized attention task validated in individuals aged 8 years and older. Change in scores on Conners Continuous Performance Test (CPT-3). | Baseline, 4-6 weeks, 6 months and 12 months. |
