The purpose of this study was to evaluate whether text messaging used as an enhancement to the Promoting Communication Tools for Advancing Language in Kids (PCTALK) intervention would result in improvements in parent engagement in a home visiting program, parent fidelity of use of the Promoting Communication (PC) strategies, and child language outcomes.  A greater number of PC strategy-focused text messages and the total number of text messages sent were associated with increases in parent engagement and parent fidelity of implementation of the PC strategies. Text messaging had an indirect effect on child communication outcomes via parent fidelity. Social validity data and implications for practice from these findings are discussed.

This monograph article describes a model for a research partnership between researchers and early childhood educators in community-based child care and early education programs designed to increase the use of evidence-based strategies for promoting communication of infants and toddlers. Through a team approach that includes close collaboration and consultation, professional development activities are linked to program, teacher, child and family needs, and to progress toward communication outcomes.

This monograph article describes eight functional, evidence-based strategies that may be used by early childhood educators, interventionists, and parents to provide infants and toddlers with language-learning opportunities across their daily routines and activities.

In this chapter, we describe the framework of a developmental model of communication and language intervention that is emerging in the research literature. Second, we discuss in more depth two promising areas of early intervention research: fostering prelinguistic communication development in very young children with developmental delays and fostering language development in young children developmentally at-risk due to impoverished environments. We conclude with a discussion of future research directions.
