The use of the Performance Diagnostic Checklist-Human Services in development of interventions to increase fidelity.

Children with Autism Spectrum Disorder (ASD) and other Developmental Disabilities (DD) often have deficits in social, play, and language which often require substantial support to develop the skills. Caregivers and educators are often tasked with developing these skills and working to transfer those acquired skill sets across settings and people (i.e. parents, day care workers, family members). Oftentimes, these naturally occurring skills are more challenging to teach since they require ongoing attention, interaction, and skill promotion from the educators and caregivers. As a result, these skills are sometimes underdeveloped or not worked on as frequently, which in turn, presents greater hardships on families and caregivers. The current study used a multiple treatment design to evaluate the efficacy of three different interventions on promoting and maintaining staff to client interactions during breaks. Treatment one included the antecedent intervention of posted rules; treatment two included the consequence intervention of posted graphical data; the final treatment was a function based treatment (based upon the results of the PDC-HS) which included direct manipulation of immediate consequences for staff to client interactions. Results showed that staff performed at a higher, and more consistent rate, when the treatment was function-based and directly/immediately related to their behavior. This simple manipulation shows promise in promoting the development of staff and family responses that are needed to enhance skill sets that are sometimes more challenging, yet necessary, to develop. © The British Society of Developmental Disabilities 2020.
