Abstract
PurposeThis clinical focus article addresses a current debate contrasting the long-standing label of “specific language impairment” (SLI) with a recent alternative, “developmental language disorders” (DLDs); the criteria for SLI yields a subset of children defined as DLD. Recent social media advocacy for DLD asserts that the two categories of children are clinically equivalent, and therefore, DLD can be used as a label for which SLI criteria would hold. Coupled with DLD advocacy is the assumption that research on SLI has not yielded clinically relevant outcomes. This clinical focus article challenges those assumptions. The clinical focus article is framed as parallels between precision medicine and evidence-based practice. The purposes of this clinical focus article are as follows: (a) revisit the legacy of research on SLI; (b) describe language development in children with SLI into adulthood; (c) address widespread but erroneous assumptions about relationships between speech impairments and language impairments, and relationships between nonverbal IQ and language impairments; (d) briefly review evidence for causal pathways; and (e) present clinical lessons from research on children with SLI.MethodNarrative review is the method used in the study.ConclusionsThe purposes of the clinical focus article were met by reviews, commentary, and supporting arguments in each section. The conclusions are that the research and clinical category of SLI is needed for accurate and precise clinical practice, including diagnosis, prognosis, clinical goals, sequencing of tasks for success, and consideration of language disorders in the context of a broad thicket of related consequences.
