Empowering Caregivers to Promote Child Independence and Persistence With Activities

Approximately 25% of children with autism are estimated to meet the criteria for profound autism. Profound autism describes those with the greatest support needs because of the coinciding significant intellectual disability and limited/absent verbal communication. Because individuals with profound autism have been excluded from research, the investigator's understanding of effective assessments and interventions for this population and their families is incomplete. One defining feature associated with caring for a child with profound autism is the 24/7 supervision required from caregivers, often described as a feeling of constant vigilance. Although previous research on the matter may not use the specific term, profound autism, much can be gleaned from studies of caregivers with adult autistic children who cannot be left alone, autistic children with co-occurring intellectual disability, or older studies including children with IQ scores below 50 before autism was well understood. Caregivers facing these 24/7 obligations experience increased time constraints that prevent their self-care routines, limit time with family and friends, and reduce time spent on personal interests and work-related activities. Caregivers also report reduced time spent sleeping, preparing meals, and completing other household duties. Some report being unable to leave their child unattended for as little as 5 minutes. Relatedly, caregivers of profoundly autistic children report some of their greatest hopes for their children to be increased independence and autonomy to engage in enjoyable activities. Teaching autistic children how to engage appropriately with items can increase independent leisure engagement and increasing sustained activity engagement can promote autonomy and overall well-being. Therefore, interventions that promote independent, sustained engagement with activities could simultaneously benefit people with profound autism and their caregivers. However, characteristic restricted interests and repetitive behaviors can impede sustained activity engagement and interfere with transitioning to new activities. Thus, additional environmental supports, such as visuals, are sometimes needed. Picture-based activity schedules are an evidence-based practice that promotes sustained engagement with activities with reduced adult assistance. However, additional research is necessary to evaluate this intervention for individuals with profound autism and their caregivers.

The proposed study focuses on alleviating vigilant-level supervision provided by caregivers for brief periods while simultaneously increasing independent, sustained engagement with meaningful activities for their adolescent children with profound autism. Participants will randomly be assigned to either the Caregiver Activity Schedules Treatment (CAST) group and receive 40 hours of training in picture-based activities or be assigned to the Treatment as Usual (TAU) group. The TAU group will be offered CAST training following the trial. The feasibility, acceptability, and preliminary efficacy will be evaluated using measures of participant performance, participant affect, clinician ratings, and independent evaluation by an expert using the Clinical Global Impressions Improvement Scale (CGI-I).
