Individuals with intellectual and developmental disabilities (IDD) present with deficits in intellectual functioning and support needs in adaptive behavior such as language, motor skills, social skills, and self-care skills (American Psychiatric Association, 2013). In addition, individuals with IDD are more likely than the general population to have physical disabilities, sensory impairments, seizures, and other health conditions such as infection, obesity, diabetes, and gastrointestinal disorders (Ouellette-Kuntz et al., 2005;van Timmeren et al., 2017). They are also at an increased risk for serious challenging behavior such as pica, elopement, and aggression, as well as self-injury, obesity, psychiatric disorders, and sleep disorders (

Disparities in diagnosis and access to healthcare and therapeutic services are well-documented for children with autism spectrum disorder (ASD) from minoritized races and ethnicities, but there is little empirical research to guide the selection and implementation of interventions and practices that will effectively support racially/ethnically diverse children with ASD and their families. This cross-over systematic review summarizes parent-mediated intervention research of children with or at risk for mental health disorders to identify potentially effective recruitment and retention strategies for diverse participants in parent-mediated intervention research for children with autism. Electronic database keyword, lead author name searches in PyschNet, MEDLINE, and ancestral searches were conducted to identify 68 relevant articles that used experimental designs to evaluate the effects of parent-mediated interventions on children with or at risk for mental health disorders. Articles were coded for participant demographics; intervention setting and type, recruitment and retention strategies, cultural adaptation of intervention, and reported attrition. Findings are discussed and applied to practices in autism parent-mediated intervention research. Suggestions for future research and limitations are discussed.
