The Effectiveness of Constant Time Delay Procedure in Teaching Body Information to Students With Intellectual and Developmental Disabilities via Telehealth

Abstract

Telehealth services, which are used effectively in teaching functional analysis and functional communication training to parents of children with autism spectrum disorder, have become more widespread and their importance has been better understood with the Covid-19 pandemic. This study aimed to examine the effectiveness of constant time delay (CTD) procedure via telehealth in teaching personal body information. The researchers conducted the study with the participation of one female and two male students diagnosed with intellectual and developmental disabilities aged between 16 and 20. It was designed with the multiple probe design with probe trials across participants. The findings of the study showed that the CTD delivered via telehealth was effective and that the behavior maintained in the follow-up sessions held 1, 2, and 4 weeks after the intervention ended, and that the participants were able to generalize these skills to other people. In addition, social validity data showed that the opinions of the mothers and teachers about the research were positive.
