In the current study, we examined the effect of a parent-implemented early communication intervention during shared book reading. Three mothers of children with autism spectrum disorder were trained and coached to use a set of reading techniques and evidenced-based naturalistic communication teaching strategies (i.e., modeling, mand-model, and time delay). Using a multiple-baseline design across behaviors, the following three components were examined: (a) the mothers' use of reading techniques with fidelity, (b) the mothers' rate and fidelity in using the three naturalistic teaching strategies, and (c) the children's communication outcomes. After training and coaching, the mothers used the reading techniques and naturalistic teaching strategies with high fidelity. The children initiated more communicative acts upon their mothers' use of time delay.

We describe a study of the internet-based Parent-Implemented Communication Strategies–Storybook (i-PiCSS), an intervention designed to train and coach parents to use evidenced-based naturalistic communication teaching (NCT) strategies (i.e., modeling, mand-model, and time delay) and RTs while reading storybooks with their young children with disabilities. Three participating parents were trained and coached via telepractice technologies (videoconferences, video editing software). Zoom software was used for videoconferencing and Camtasia software was used to record the training and coaching sessions and to edit the recorded session for feedback delivery purposes. Using a single-case multiple-baseline design across NCT strategies within each family, we examined (a) parents' fidelity use of the three NCT strategies, (b) parents' use of book RTs, and (c) child language and communication outcomes. The entire intervention period lasted 8 weeks. After training and coaching, parents used the modeling, mand-model, and time delay strategies with higher rates and higher quality (accuracy). Children initiated more communicative acts upon parents' use of time delay and increased their numbers of single- and multiple-word responses. [ABSTRACT FROM AUTHOR]
