An interventional study of Social virtual reality and Traditional social skills in Attention-Deficit/Hyperactivity Disorder, sponsored by The Hong Kong Polytechnic University. Status unknown. Open to participants aged 6 Years to 12 Years. Per ClinicalTrials.gov, last updated 2022-10-05.
Sponsored by The Hong Kong Polytechnic University · Not applicable, Interventional, and Supportive care
The study targets children with diagnosed ADHD and aims to (1) develop a social virtual reality based (SocVR) intervention and (2) investigate its effects on improving the social skills and executive functioning of inhibitions, emotional control and attention of the children compared to traditional social skills training.
The study will be a three-arm parallel randomised controlled trial comparing the effects of a SocVR with traditional social skills training on social skills and executive functioning of children with ADHD. The study period is 2 months, including 4 weeks (2 sessions per week) of intervention and control, followed by a 4-week follow-up. The participants will be assessed at three time points (i.e. at baseline, 4 weeks and 4 weeks follow-up).
The guidelines of Whitehead et al. (2016) suggested that recommended that at least 16 subjects per group for medium effect size in pilot RCT and 15% attrition over time can be expected. Thus, the minimum sample size per group was 20. A total of 60 participants will be recruited in which 20 participants in the social VR group, 20 in the traditional social skills group and 20 in the waitlist control group.
Social VR Intervention During the Social VR intervention, one RA will also appear as one avatar in the scenario to guide the participants to complete a series of tasks. Each intervention session will be conducted in a classroom independently for each participant.
Traditional social skills training The training lasts 20 minutes which depends on the emotion of the participants. Each training session will be conducted in a classroom independently for each participant.
Sample size The guidelines of Whitehead et al. (2016) suggested that recommended that at least 16 subjects per group for medium effect size in pilot RCT and 15% attrition over time can be expected. Thus, the minimum sample size per group was 20. Based on the guideline of Whitehead et al. (2016), a total of 60 participants will be recruited in which 20 participants in the social VR group, 20 in the traditional social skills group and 20 in the waitlist control group. This sample size is comparable to those used in the published pilot study on children with ADHD. For instance, van der Oord et al. (2014) recruited 40 participants (20 in the control group and 20 in the interventional group) to examine the efficacy of computerized executive functioning remediation training with game elements in children with ADHD.
Recruitment Participants will be recruited from six primary schools and community centres. Interested participants or parents who provide written informed consent will be further evaluated for inclusion and exclusion criteria by a trained research assistant. Participants who meet the inclusion criteria in the study will be invited to perform an IQ test at the university at baseline.
Randomisation Eligible participants will be randomized to the SocVR group, traditional social skills training group or waitlist control group. A computer-generator randomiser will be used to generate the random allocation list. The randomisation will be undertaken by another research assistant not directly involved in the study. A number generated by the computer will be assigned to each eligible subject who will be randomly allocated to the three different groups by using the number. The participants and their parents or legal guardians will be blind to the assignment process. Parents or legal guardians will receive an email and a telephone call with notification to Group 1, Group 2 or Group 3.
Statistical analysis All statistical analyses will be performed in SPSS version 26.0 software (IBM Corp, Armonk, NY, USA) and are two-sided with a level of significance of \< 0.05. Demographic information of the participants will be summarised with frequency and percentage for categorical variables. The continuous variables will be summarised by mean and standard deviation. The change between baseline and week 4 within each arm will be tested using t-tests. To examine the between-group difference in terms of measure outcomes from baseline to week 4, repeated analyses of covariance (ANCOVA) with adjustment of baseline characteristics will be conducted. To evaluate the improvement during the intervention period among the three groups, f-tests will be performed on primary and secondary outcome measures at the beginning of the first session and at the end of the last session. An intention-to-treat analysis will be performed. This analysis is regarded as the most appropriate approach to analyse RCT data by the highest-quality journals, which have utilised the CONSORT standard.

Exclusion Criteria:
Social VR (SocVR) intervention is developed to enhance the social interaction skills of children. The participants will wear a head-mounted display (HMD) for the SocVR intervention. Each session of the SocVR intervention lasts for a maximum of 20 minutes to ensure the participants focus on the intervention and prevent causing any physical effect (Yamaguchi, 1999). The intervention contains three real-life virtual scenarios, including (1) classroom and playground, (2) MTR station and compartment, and (3) street and building. One scenario will be adopted in each session. The sequences of the scenarios used in each session will be the same for all participants. During the SocVR intervention, one RA will also appear as one avatar in the scenario to guide the participants to complete a series of tasks. Each intervention session will be conducted in a classroom independently for each participant.
Behavioral: Social virtual reality
An experienced special educational needs (SEN) teacher will teach the participants social interaction skills through tradidactic instructions and role-play activities. Four modules will be covered in the 4-week training: (1) how to introduce yourself and basic social skills; (2) how to listen to others; (3) how to share with others; (4) learn to know how people feel and how to empathise. These modules have been applied in many studies (Braswell \& Bloomquist, 1991; Huang et al., 2015). The content of this training will be as similar as possible to the SocVR training. The training lasts 20 minutes which depends on the emotion of the participants. Each training session will be conducted in a classroom independently for each participant.
Behavioral: Traditional social skills
With reference to Beck et al. (2010), the participants in this group will receive no training and they can participate in the social VR training after the intervention period. To ensure the consistency of the experiment, the participants are not allowed to initiate or change their pharmacological treatment during the 8-week intervention period.
The participants will receive eight training sessions in 4 weeks (2 sessions per week). Each session is about 20 minutes.
