Measure of Inclusion Criteria: a 110-question coding survey to address issues relevant to communication and language intervention research. Informing the development of the survey were resources including the What Works Clearinghouse Procedures and Standards Hand-book 3.0 (WWC Procedures and Standards, 2014), the Division for Early Childhood Recommended Practices (DEC-RP, 2014). Broadly, the coding survey questions included: citation information, purpose of the study, child and adult participant characteristics including cultural and linguistic diversity, disability and risk status, research design, numbers of participants and attrition, intervention type, length and procedures, measurement features – technical adequacy, fidelity of intervention, training and professional development, analytic approach, reported results, study limitations and implications.
