Susceptibility to Peer Influence in Adolescents with Mild-to-Borderline Intellectual Disability (MBID). Adolescents with MBID seem more susceptible to peer influences than adolescents without MBID, which could contribute to their heightened risk taking. In my PhD project, I investigate why this would be, under which circumstances this is especially the case and how we can support adolescents with MBID to how more peer resistance. Moreover, I study whether peer influence can also be positive for adolescents with MBID and can increase their prosocial behavior.
