Comparative Effectiveness of Caregiver Training in Mindfulness-Based Positive Behavior Support (MBPBS) and Positive Behavior Support (PBS) in a Randomized Controlled Trial

Abstract

Caregivers of individuals with intellectual and developmental disabilities are often stressed due to the demands of the job, including the nature and severity of challenging behaviors of the clients, work conditions, degree of management support for the staff, and the demands of implementing some interventions under adverse conditions. Mindfulness-Based Positive Behavior Support (MBPBS) and PBS alone have been shown to be effective in assisting caregivers to better manage the challenging behaviors of clients with intellectual and developmental disabilities. The aimof the present study was to undertake a head-to-head assessment of the effectiveness of MBPBS and PBS alone in a 40-week randomized controlled trial. Of the 123 caregivers who met inclusion criteria, 60 were randomly assigned to MBPBS and 63 to PBS alone, with 59 completing the trial in the MBPBS condition and 57 in the PBS alone condition. Results showed both interventions to be effective, but the caregiver, client, and agency outcomes for MBPBS were uniformly superior to those of PBS alone condition. In addition, the MBPBS training was substantially more cost-effective than the PBS alone training. The present results add to the evidence base for the effectiveness of MBPBS and, if independently replicated, could provide an integrative health care approach in the field of intellectual and developmental disabilities.
