| Popis | Background: Children with early language delays are at increased risk of persistent language impairment. Early identification and intervention are desirable. Parent-report inventories are useful screening tools, but the screening context places limits at their length. Validity of parentreport screening tools in languages other than English has been rarely reported in detail. Aims: The aim was to establish the concurrent validity of an existing 40-item parent-report vocabulary screening tool in Czech, using a picture-based examiner-administered comprehension and production task as a concurrent measure of vocabulary. Methods & Procedures: Parents of 200 children aged 1;3 to 3;6 were given the screening inventory, in which they were asked if their child says or comprehends each of 40 words. At the same time, children were administered a picture-based comprehension and production task. Concurrent validity of the inventory was examined using correlations, partial correlations, and regression analyses controlling for age. Outcomes & Results: The partial Spearman correlation (controlling for age) between production scores from parent-report and production scores from the examiner-administered task was 0.53; for comprehension, the correlation between parent report and test scores was 0.36. These values are similar to those reported for short and full versions of MacArthur-Bates CDI for 2-year-olds. Conclusion & Implications: A 40-item tool shows clear concurrent relations with an examineradministered picture comprehension and production task. The study demonstrates that short parent-report tools may be useful in early identification of language impairments, and they may be a good option particularly in languages that have limited repertoire of assessment instruments. |
