| Description | The paper reports on a standardization of a short parent-report screening tool for quick assessment of vocabulary in children aged 16 to 42 months. The tool should capture the early signs of a delayed or disrupted language development. The method asks for children’s use and comprehension of 40 words. Participants. The tool was standardized on a group of 1047 children (535 boys) that was demographically diverse and was obtained in different regions of the Czech Republic. Analysis. Developmental norms and growth curves were calculated using generalized additive linear models. Linear regression was used to test the effects of various demographic factors on the scores. Results. The norms correspond to the expectations about the growth of vocabulary with age. Girls show statistically significant advantages in both production and comprehension. Statistically significant but weak relations were found between comprehension scores on one hand, and maternal education and population size of the hometown on the other. Limitations. The method is based on parent reports, which may result in lower reliability. This norming study has not directly assessed concurrent validity with other methods |
