Parent Implementation of DTT Following Telehealth Instruction

Discrete Trial Training (DTT) is a method of intervention for individuals with Autism Spectrum Disorder (ASD). Applications of DTT require prescribed repetitions of instruction. DTT is typically implemented via trained instructors or teachers. However, prior analysis has demonstrated the potential of parent-implemented DTT. Prior research demonstrated that DTT training can be implemented with a high degree of fidelity using a student teacher population. However, to date, no studies have evaluated the use of a DTT telehealth training with parents of children with ASD. The purpose of this study was to evaluate the feasibility of a remote parent training method to allow parents to implement DTT in home settings. To this end, three parent participants of children diagnosed with ASD were trained to implement DTT through a telehealth modality in a nonconcurrent multiple baseline design. Results suggested efficacy of this method at DTT skills acquisition.
