Effectiveness of the serious game ‘You & I’ on the mentalizing abilities of adults with mild to borderline intellectual disabilities: a parallel superiority randomized controlled trial
Abstract Background: Persons with mild to borderline intellectual disabilities generally show dysfunctions in mentalization, including impairments in stress regulation, resulting in problematic social relationships and personal distress. Inteention programs can, however, improve mentalizing abilities. The aim of this study is to examine the effectiveness of the serious game ‘You & I’ on mentalizing abilities and stress regulation in adults with mild to borderline intellectual disabilities. Methods: A two-arm, parallel, superiority randomized controlled trial will be used with 172 adults with mild to borderline intellectual disabilities. Participants will be randomly assigned to either the experimental group to play the serious game ‘You & I’ or a waitlist control group. Participants will be assessed at baseline, post-intervention (5 weeks after baseline), and follow-up (6 to 8 weeks after post-intervention). They also will fill in questionnaires measuring personal factors, personal development, and personal well-being, social validity, and autism spectrum quotient (demographic variables), mentalizing abilities (primary outcome measure), and stress regulation (secondary outcome measure). Discussion: The serious game ‘You & I’ aims to improve mentalizing abilities in adults with mild to borderline intellectual disabilities, which is expected to lead to improved regulation of stress in social relationships. The study’s unique feature is the use of a serious game to improve mentalizing abilities, which is expected to provide insight into the game’s effectiveness for adults with mild to borderline intellectual disabilities. If the intervention is effective, the serious game can be implemented on a broad scale in Dutch care organizations for people with intellectual disabilities as an effective tool to improve mentalizing abilities. It will be made available online, free of charge. Trial Registration: Nederlands Trial Register NTR7418 (registered 2 August 2018).
