Impact of Mindfulness-Enhanced Pivotal Response Group Treatment on Parenting Stress: A Randomized Controlled Trial

One of the core features of Autism Spectrum Disorder (ASD), social communication impairment, presents in a variety of ways, including reduced functional language use and social initiations, which often warrant intensive intervention services. Additionally, parents of children with ASD demonstrate increased levels of parenting stress when compared to parents of typically developing children and children with developmental delays. Elevated parenting stress has been shown to diminish positive treatment outcomes, which lends support to develop methodologies to concomitantly target child and parent behaviors. The current randomized control trial (RCT) uses a dual-pronged approach to directly target both child communication deficits and parenting stress within a group format. This RCT combined an empirically supported behavioral therapy, Pivotal Response Treatment (PRT), with components from Acceptance and Commitment Therapy and Mindful Parenting for reducing parenting stress. Caregivers and their minimally or pre-verbal child with diagnosed or suspected ASD were randomly assigned to one of the following supplemental conditions: mindfulness-enhanced PRT (mPRT) or psychoeducation-enhanced PRT (pPRT) as an active control condition. The current study assessed feasibility and acceptability in addition to demonstrating proof of concept in regard to additive effects of mPRT compared to pPRT.
