Abstract

Clinical Question: Which current speech and language interventions or techniques are effective for improving speech and language outcomes for children with speech and language delays in the birth-to-3 population?

Method: Scenario Review

Study Sources: Cumulative Index of Nursing and Allied Health Literatures (CINAHL), Education Resources Information Center (ERIC), Language and Linguistics Behavior Abstracts (LLBA), Medline, PsycINFO, ProQuest Digital Dissertations (PQDD), Cochrane Central Register of Controlled Trials, Google Scholar, Scirus, SCOPUS, Science Direct, and the American Speech-Language-Hearing Association Conference Proceedings

Search Terms: Intervention OR Treatment AND child language, child speech, late talkers, language delay, language impairment, gestures, modeling, focused stimulation, parent training, prelinguistic milieu teaching, responsivity education and Hanen.

Number of Included Studies: 8

Number of Participants: Total = 276; Treatment total = 143; Control total = 133

Primary Results: (1) Of the included interventions, The Hanen Program in combination with focused stimulation conclusively improved speech and language outcomes, specifically increasing vocabulary size, expanding phonetic inventories, and increasing syllable structure repertoires. (2) Of the included intervention techniques, expansion, recasting, parallel talk, child directed speech, visual cues, feedback, and increasing interaction opportunities showed large effects on increasing the mean length of utterances, the total number of words, the number of different words, and the percentage of intelligible utterances.

Conclusions: There is conclusive evidence that the Hanen Program with focused stimulation improves outcomes for children with speech and language delays in the birth-to-3 population. Additionally, the intervention strategies of expansion, recasting, parallel talk, child-directed speech, visual cues, feedback, and increasing interaction opportunities were also highly likely to improve speech and language outcomes. Because the overall effectiveness of responsivity education/prelinguistic milieu teaching and modeling alone as an intervention technique could not be derived from the current studies, further research is recommended.
