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

The purpose of this study was to evaluate the effects a parent training programin Korea using the Teacher Performance Rate Accuracy Scale (TPRA)during training and video self-monitoring on the rates of accurate discretetrial Teaching (DTT) and children’s correct responses. The study was conductedin an early intensive behavior intervention (EIBI) program of a publicchildren’s hospital in Korea. Two mothers who had children enrolled in theEIBI services participated in the study. A delayed multiple baseline acrossparticipants design was used. The training program consisted of individualcoaching with therapist-conducted TPRAs and group instruction on parentself-monitoring using TPRA for self-evaluations. Results indicated thateach parent’s average rates of accurate DTT presentations increased and therates of error presentation decreased after the intervention. As a result, theirchildren’s average percentage of correct responses increased during interventionand maintained after intervention. Results of this study suggest that thistraining program is promising and has potential for a large-scale implicationin Korea.
