| Sumario: | 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.
