Self-Regulation in Children With Neurodevelopmental Disorders "SR-MRehab: Un Colegio Emocionante": a Protocol Study With Virtual Reality
Children with neurodevelopmental disorders may show difficulties in self-regulation. The main objective of this study is to improve self-regulation skills in children between 6 and 11 years old with neurodevelopmental disorders. Methodology: A randomized controlled trial will be conducted with the use of "SF-MRehab: Un colegio emocionante", a non-inmersive virtual reality system where virtual objects can be managed by children in a natural way by using their hands. Children will be recruited from several schools from Granada (Spain) and they will be randomly allocated to two groups. Assessment will be conducted before and after the intervention as well as 24 weeks after the end of the intervention process. Experimental group will receive the intervention using virtual reality. Control group will receive the intervention through a standard self-regulation program. Both interventions will be performed once a week for a total of 10 sessions. Changes in self-regulation, as well as acceptability of technology with the use of SR-MRehab will be evaluated. The results will be published and will contribute with evidence regarding the use of this type of intervention on children with neurodevelopmental disorders
The "SR-MRehab: un colegio Emocionante" is a randomized controlled trial, a non-inmersive virtual reality system will be conducted through Mrehab tool (39, 40). Children will be recruited from several schools from Granada (Spain) and they will be randomly allocated to two groups: experimental or control group. Assessment will be conducted before and after the intervention as well as 24 weeks after the end of the intervention process. Experimental group will receive the intervention using virtual reality. Control group will receive the intervention through a standard self-regulation program. Both interventions will be performed once a week for a total of 10 sessions (50 min sessions per day). The inclusion criteria are: 1) have special educational needs; 2) possible oral comprehension, with the possibility of fixing the gaze; 3) be able to attend to verbal and visual instructions; 4) maintain sustained attention for at least four minutes. Exclusion criteria are: 1) severe motor disability; 2) children with major behavioural problems, such as self-harm; 3) children with high abilities. Initially, all students of this center with special educational needs will be invited.
2.2. Procedure and Enrollment The implementation of the program covers the period from September 2019 to May 2020, divided into six stages: recruitment, pre-evaluation, assignation, intervention, post-evaluation and follow-up at 6 months. The initial stage corresponds to the acceptance by the management of the centers, and the subsequent invitation to the participants by sending a letter to the parents/legal guardians, which contains an informative document of the characteristics of the project and the corresponding informed consent for participate in it. Children are randomly assigned through the online randomization program. The type of allocation to each group will be by simple randomization. Recruitment and study procedure is shown in Figure 1 2.2.1. Study Variables The main variables of the study can be divided into two main dimensions: 1) executive functions: inhibitory control, flexibility, planning, reasoning, and problem solving; 2) socio-emotional competences: recognition of emotions, emotional regulation and social competence. These variables were and will be evaluated through several questionnaires provided to parents, teachers and students and test performed by children, as shown in Table 1.
Additionally, other sociodemographic data and information on the child's development and learning history were collected. Through the "SR-MRehab: un colegio emocionante", in each session, the following information will be collected for each task: number of hits, cognitive errors, time each participant to complete the task.
The assessment will be made in the first weeks of December 2020, dividing the assessment into three blocks. First, the EQ-i:YV questionnaire (41) and Clocks and Affect Recognition subtests from NEPSY-II (42) will be provided to students, and on the other hand, teachers and parents will asked to complete the EPYFEI-Escolar (44) and EPYFEI (45) questionnaires respectively, they'll have to fill in and come back within the next week. Second, the students will complete the assessment corresponding to the subtests of Design Fluency and Theory of Mind of the NEPSY-II. Finally, in a third session, they will carry out a final block to assess executive functions through Trail Making Test A and B (TMT A-B) and Stroop test.
The same evaluation will be carried out immediately after finishing the program. In addition, the acceptability of the technology will be evaluated with the children at the end of each session and at the end of the whole program. A combination of methods will be used to assess acceptability (46). Firsts, in each session, a visual analog scale will be used to evaluate each activity, type Smileyometer, which consists of a visual analog scale with coding based on a 5 point Likert scale (Horrible=1; Great=5). In addition, at the end of the program the method "This or That" will be used, though five questions, for example: what has been the most fun of the program? Or what game would you like to have at home?. To check the maintenance of the results of the program, a follow-up will be carried out at 3 months, in which the emotional regulation and executive functioning in the children will be re-assessed.
2.2.3. Intervention 2.2.3.1. Experimental Group Intervention on self-regulation will be carried out through a non-immersive virtual reality platform, "SR-Mrehab: Un colegio emocionante" in which students must conduct a series of activities designed specifically for this purpose. These activities will be performed by the children using mainly their hands to manage the virtual objects showed in the screen. To do this, our system make use of a Kinect motion sensor connected to the computer to control the body movements of the children. Moreover, our system records some relevant data of the execution of these activities for further analysis of the children's performance.
The exercises will be divided into two blocks, emotional regulation (ER) and cognitive regulation (CR), in a total of 10 sessions, once a week, performing an exercise of each block per session. Each session will consists of 60 minutes. In general, each session will take into account the development of the various executive functions: working memory, inhibitory control, flexibility, reasoning, planning and problem solving (15) and emotional competencies divided into the following dimensions: perception and emotional awareness, emotional regulation, emotional autonomy and social competence (47). Table 2 lists the organization, description and aims of each session. These sessions will take place from January to April 2021.
The MRehab tool allows establishing five levels of difficulty. Before starting the intervention program, a database will be created with each participant, assigning each of the tasks designed for each child according to the results of the previous assessment.
The intervention will begin with the explanation of the group session of 3 to 4 children. Subsequently, individually in order to record the responses and perform the activities, it will be asked to perform different tasks with the support and supervision of the occupational therapist and psychologist. The session would end with a small assembly in which each child discusses their experience and how and where the skills learned could be generalized in their activities of daily living. Each session will be one hour long.
2.2.3.2. Control Group
The children from control group will follow a program of emotional education of Primary Schools, though group activities in the classroom (5, 49). Each session will last 50 minutes, just like in the experimental group. The content of the sessions will include 5 sessions of emotional awareness and 5 sessions of emotional and cognitive regulation. The activities are similar as those listed in Table 2 for the experimental group, but the virtual reality system will not be used. It will be held in parallel in another room of the school, on the same day and time, carried out by occupational therapists and students from the students in the last year of occupational therapy degree.
