BACKGROUND AND PURPOSE: Standard @entity2026 scales such as the Boston Diagnosis @entity2026 Evaluation are inappropriate for use in @entity64 . Likewise, global @entity64 scales do not reliably detect @entity2026 , and existing brief @entity2026 screening scales suitable for @entity1 with @entity64 have several limitations. The objective of this study was to generate and validate a bedside language screening tool, the Language Screening Test, suitable for use in the emergency setting. METHODS: The Language Screening Test comprises 5 subtests and a total of 15 items. To avoid retest bias, we created 2 parallel versions of the scale. We report the equivalence of the 2 versions, their internal and external validity, and their interrater reliability. We validated the scale by administering it to 300 consecutive @entity1 within 24 hours after admission to our @entity64 unit and to 104 stabilized @entity1 with and without @entity2026 using the Boston Diagnosis @entity2026 Evaluation as a reference. RESULTS: The 2 versions of the Language Screening Test were equivalent with an intraclass correlation coefficient of 0.96. Internal validity was good; none of the items showed a floor or ceiling effect with no redundancy and good internal consistency (Cronbach a 0.88). External validation against the Boston Diagnosis @entity2026 Evaluation showed a sensitivity of 0.98 and a specificity of 1. Interrater agreement was near perfect (intraclass correlation coefficient, 0.998). The median time to complete the Language Screening Test was approximately 2 minutes. Importantly, the Language Screening Test does not need to be administered by a speech and language therapist. CONCLUSIONS: This comprehensively validated language rating scale is simple and rapid, making it a useful tool for bedside evaluation of @entity1 with @entity64 in routine clinical practice.

Validation of a new language screening tool for XXXX with @entity64 : the Language Screening Test (LAST).
