Abstract: Individuals diagnosed with an intellectual disability (ID) share overlapping traits with those diagnosed with both ID and an Autism Spectrum Disorder (ASD). Therefore, the purpose of this study was to determine if caregivers’ reports of symptoms of ASD are of value (i.e., when comparing them to clinical diagnoses of ASD) and to determine which symptoms of ASD best differentiate those with ASD from those with ID only. It was hypothesized that a subset of items would emerge using the Autism Spectrum Disorders-Diagnostic for Adults (ASD-DA) which would differentiate the two groups utilize in this study. One hundred eighty-six adults diagnosed with ID with and without diagnosis of ASD were assessed for core symptoms and other behavioral differences using the ASD-DA. Most of the individuals in the ID group (n =93) and the ID plus ASD group (n =93) were in the profound range of ID. The items which were most likely to distinguish individuals with ASD were in socialization domain. Furthermore, adults with ASD were more likely to be male and to be non-verbal.

Video modeling with other as model (VMO) is a more practical method for implementing video-based modeling techniques, such as video self-modeling, which requires significantly more editing. Despite this, identification of contextual factors such as participant characteristics and targeted outcomes that moderate the effectiveness of VMO has not previously been explored. The purpose of this study was to meta-analytically evaluate the evidence base of VMO with individuals with disabilities to determine if participant characteristics and targeted outcomes moderate the effectiveness of the intervention. Findings indicate that VMO is highly effective for participants with autism spectrum disorder (IRD=.83) and moderately effective for participants with developmental disabilities (IRD=.68). However, differential effects are indicated across levels of moderators for diagnoses and targeted outcomes. Implications for practice and future research are discussed. [Copyright &y& Elsevier]
