Vocabulary Intervention for Bilingual Children with Specific Language Impairment: A Review of Existing Literature

Jessie Bereda, BA, Li Sheng, Ph.D.

vSpecific language impairment (SLI, currently referred to as developmental language disorder, DLD) affects 7-8% of children in kindergarten (NIDCD, 2017). Various aspects of language may be impacted, including the timely acquisition of vocabulary.

vTypically developing bilingual children may similarly present with diminished vocabularies in either of their languages, an effect referred to as distributed knowledge (Oller, Pearson, & Cobo-Lewis, 2007).

vBilingual children with SLI may consequently present with greater vocabulary deficits than either group alone. Lexical development can be further inhibited by lack of exposure to rich language input in home and/or school environments (Simon-Cereijido, 2015). Intervention targeting lexical development in this population is critical, as vocabulary skills may functionally impact social communication, literacy, and future academic achievement (McGregor & Duff, 2014).

vThis project seeks to evaluate the efficacy of vocabulary interventions implemented with bilingual children at risk for or diagnosed with SLI.

Five databases (ERIC, PubMed, PsycINFO, Web of Science, Taylor & Francis Online) were searched using search terms “bilingual” AND “vocabulary intervention” at two time points. The following inclusionary criteria were used:

v Included bilingual children (of any language background) with or at risk for SLI

v Included pre- and post-intervention measures of vocabulary

309 articles screened by title and abstract, 9 selected.v 7 peer-reviewed articlesv 2 doctoral dissertations

Articles were grouped by type of research questions asked to yield the most appropriate comparison.

vTwo studies compared bilingual intervention vs. no intervention (Simon-Cereijido & Gutiérrez-Clellen, 2014; Tysbina & Eriks-Brophy, 2010).Ø Intervention group showed vocabulary gains while control group did not.

vFour studies compared bilingual vs. monolingual intervention (Rau, 2014; Restrepo, Morgan, & Thompson, 2013; Thordardottir, Cloutier, Ménard, Pelland-Blais, & Rvachew, 2015; Thordardottir, Weismer, & Smith, 1997). Ø Bilingual intervention is as effective as monolingual intervention (Thordardottir et al.,

2015; 1997), with added benefit of first language support (Restrepo et al., 2013). vWhenever possible, clinicians should aim for bilingual intervention when working

with clients who are developing skills in two languages. vAlthough further evidence is needed, one study suggested that parents can be

trained in delivering intervention in L1 (Thordardottir et al., 2015).

v Three studies compared order of languages within a bilingual intervention (Fierro, 2017; Lugo-Neris, Bedore, & Peña, 2015; Perozzi, 1985).Ø It is unclear which order of languages is most effective. v Studies with stronger methodology (e.g., increased sample size, reported

intervention procedures for replication) are warranted.
