Milestones of language development in Turkish children. Objectives: Language delays are common in child- hood, may be associated with delays in other areas of development, and can affect school performance. Various tests designed for general developmental screening or specifically for language are used to assess developmental status in preschool children. Knowledge of the probabilities of normal developmental milestones may simplify detection of problems and delays. The aim of this study was to determine the milestones of language development in Turkish children. Patients and methods: We assessed data from application of the Denver II Developmental Screening Tests Turkish standardization to 1,993 children, 976 (49.0%) boys and 1,017 (51.0%) girls aged 0.6-82.0 months. We used binary logistic regression to analyze the predicted probability of accomplishing the language items on the Denver II Develop- mental Screening Test. Results: We determined the sequence of assessed language items and the ages associated with accomplishing those items, as well as the ages at which 25, 50, 75, and 100% of children passed the items. Language items followed a sequential route. Graphs had polynomial slopes. Conclusion: Curves for normal development allow detection of aberrations in the predicted course of language develop- ment, and may facilitate earlier diagnosis of delays in language.
