Abstract View Full Summary
Rationale: Without knowledge of dual language profiles, disproportionate numbers of dual language learners (DLLs) are misdiagnosed with developmental language disorders (DLD). This study investigated the appropriateness of standardized assessments of expressive language in Jamaican Creole (JC)-and-English-speaking preschoolers. We interpreted results based on adult models from the same linguistic community. Three research questions (RQs) were addressed.
Methods: One-hundred-and-seventy, 4-to-5-year-old JC-and-English-speaking preschoolers completed the CELF-P2 (Wiig et al., 2006) Word Structure and Expressive Vocabulary subtests. Thirty-three, 24-to-51-year-old adult JC-English-speakers completed the same subtests. Scoring adaptations for JC-influenced productions were developed based on adult models.
Results: JC-English-speaking children differed significantly from the standardized sample (RQ#1). JC-English-speaking preschoolers and adults used similar linguistic structures suggesting language difference, not disorder. Adult models were critical to the accurate interpretation of preschoolers’ performances (RQ#2). The CELF-P2 original and adapted scores were significantly different, with a pattern of over-diagnosis of up to 41% (RQ#3).
Conclusions: Adapting standardized assessments using adult models supports the accurate identification of DLDs in DLLs. The need for research to guide assessment of JC-English-speakers will be discussed.
