School-Based Speech-Language Pathologists' Perspectives on Diagnostic Decision Making.

PURPOSE

This study used a structured open interview approach to elicit information from school-based speech-language pathologists (SLPs) regarding their assessment practices for children with suspected language impairment.

METHOD

Phone interviews were conducted with 39 school-based SLPs who were employed across the United States. The interviews explored assessment topics related to assessment tool selection and rationale and the integration of assessment data to determine treatment eligibility.

RESULTS

The results of this study suggest that SLPs use both standardized testing and informal testing for their diagnostic procedures. Standardized testing appears to be the tool that drives diagnostic decisions regarding eligibility and severity. Informal measures, such as parent/teacher interviews and language sampling, were used by school-based SLPs to gather information regarding naturalistic language use; however, they seem less important in the diagnostic decision-making process. Also, SLPs reported completing language sample transcription and analysis in real time while interacting with a child.

CONCLUSIONS

School-based SLPs appear to rely on the results from standardized testing when determining treatment eligibility for children with language impairment. The reliance on standardized testing appears to be driven by institutional policies. We discuss the potential impact of federal/state/district guidelines on diagnostic decisions and consider the research-to-practice gap.
