Objective: This investigation was conducted to evaluate the effect of training parents in indirect language stimulation on parent behavior with their late talking toddlers during play through telepractice. Method: An A-B design with follow up was selected for this investigation and included one participant. The independent variable was parent training through telepractice in the use of indirect language stimulation techniques. The primary dependent variable was the cumulative number of times the parent used ILS correctly during a 10-minute play session. Results: Visual analysis revealed an immediate positive therapeutic change for participant one and carryover during the follow up phase. Percentage of nonoverlapping data was 100% with all treatment data points falling outside the range of the baseline data points. A parent questionnaire administered pre and post training also suggested a shift in a parent’s understanding of adult communication behavior and its impact on late speaking toddlers. Conclusion: Results of this investigation supported the hypothesis that parents’ behavior will change positively when trained to use indirect language stimulation techniques during play with their late talking children.
