HomeGoals Preliminary Investigation: Williams (2022) examined the effects of the HomeGoals Parent Coaching Program (HG-PCP), a tailored coaching program for parents of toddlers with expressive language delay. The HG-PCP is designed to support families with their current needs by providing diagnosis education, implementing an intervention in natural environments, and preparing them to provide ongoing support for their child’s early language needs, thereby decreasing parent-perceived stress. Method: This investigation utilized multiple baselines across participants designed to examine the effects of the HG-PCP, increase knowledge and skills in implementing treatments, and decrease parent stress. Two parent-child dyads participated in the investigation three times a week for five weeks. Results: Results indicate that the HG-PCP positively affected parent knowledge and skills. Further, as knowledge and skills increased, perceived parent stress decreased. Conclusion: These findings reveal that HomeGoals may be considered an effective program that increases parent knowledge and skills while decreasing perceived parent stress and mitigating expressive language gaps in the 16-42-month population. These findings support the need for professionals working in early intervention to empower parents with information systematically to offset parents’ perceived stress. Future research will replicate the investigation with parent- child dyads, train additional SLPs to implement HG-PCP to compare validity and reliability, and investigate dosage protocols to suggest best practice standards to reduce expressive language gaps. Keywords: diagnosis education, early intervention, parent coaching, parent implementation, parent stress, speech, and language delays HomeGoals Impact on Language Acquisition: Although expressive language was not directly measured in this investigation, the expressive language outcomes are worth mentioning. During pre-intervention, each participant completed the HG-WordBank—this list of words comprised commonly used sounds and words from birth to 36 months. Participants were directed to use the HG-WordBank based on personal preference (e.g., ongoing recording of newly acquired words, weekly recording, monthly). Participants saw frequent increases in their child's expressive language growth and reported newly learned words regularly. Providing tailored support, encouraging daily practice, and observing child language growth increased parent motivation to practice. Each participant's child was reported and observed to have expressive language at or above age level by post-intervention (See pre and post-scores below).
