Optimizing a Vietnamese Sentence Repetition Task Using Item Response Theory.

ABSTRACT:

Purpose

Sentence repetition can contribute to the identification of developmental language disorder (DLD). However, few studies have attempted to optimize the task for clinical practice. This study uses the item response theory (IRT) to optimize a Vietnamese sentence repetition task for screening and full-assessment purposes and evaluate the diagnostic utility of the new item sets.

Method

We expanded the original task from 28 to 40 items to maximize the chances of having robust final item sets. The 40 items were administered to 196 children in Vietnam, ages 4-6 years. Participants met criteria for DLD (n = 28) or typical development (n = 122), while a subset did not meet criteria for either classification (i.e., Risk, n = 46). Using IRT, we compared diff
