Abstract

Concerns regarding Mean Length of Utterance (MLU) has led to adaptations of this method of analysis. A recent study by Johnston (2001) introduced an alternative to MLU called MLU2. The current study investigates the split-half reliability of MLU and MLU2 as well as another alternative, Median Length of Utterance (Med-LU). Split-half reliability was found for these methods when segmented into Phonological and Communication Units. Split-half reliability of MLU2 was generally higher than that of MLU, and both were higher than Med-LU. The study suggests that MLU2 may also be a valuable tool for clinicians in analyzing child language.
