Research to Establish the Validity, Reliability, and Clinical Utility of a Comprehensive Language Assessment of Mandarin

Purpose

With no existing gold standard for comparison, challenges arise for establishing the validity of a new standardized Mandarin language assessment normed in mainland China.

Method

A new assessment, Diagnostic Receptive and Expressive Assessment of Mandarin (DREAM), was normed with a stratified sample of 969 children ages 2;6 (years;months) to 7;11 in multiple urban and nonurban regions in northern and southern China. In this study of 230 children, the sensitivity and specificity of DREAM were examined against an a priori judgment of disorders. External validity was assessed using 2 indices of language production for different age groups.

Results

External validity was assessed against spontaneous language indices (correlation range: r = .6–.7; all ps r = .45, p Conclusion
