Instructing Parents to Deliver Discrete Trial Teaching to Their Children with Autism Spectrum Disorder in Korea

Abstract

The purpose of this study was to evaluate the effects a parent training program
in Korea using the Teacher Performance Rate Accuracy Scale (TPRA)
during training and video self-monitoring on the rates of accurate discrete
trial Teaching (DTT) and children’s correct responses. The study was conducted
in an early intensive behavior intervention (EIBI) program of a public
children’s hospital in Korea. Two mothers who had children enrolled in the
EIBI services participated in the study. A delayed multiple baseline across
participants design was used. The training program consisted of individual
coaching with therapist-conducted TPRAs and group instruction on parent
self-monitoring using TPRA for self-evaluations. Results indicated that
each parent’s average rates of accurate DTT presentations increased and the
rates of error presentation decreased after the intervention. As a result, their
children’s average percentage of correct responses increased during intervention
and maintained after intervention. Results of this study suggest that this
training program is promising and has potential for a large-scale implication
in Korea.
