“…The MB-CDIs have been extensively used as research tools to describe the language profiles of bilingual children (see O'Toole et al, 2017, for a recent cross-linguistic comparison on bilingual children) and clinical populations, for example children with genetic syndromes, autism spectrum disorders, and cochlear implants, among others (Charman, Drew, Baird, & Baird, 2003;Deckers, Van Zaalen, Mens, Van Balkom, & Verhoeven, 2016;Thal, DesJardin, & Eisenberg, 2007). These studies confirmed the usefulness of the MB-CDIs in describing lexical development trajectories and in highlighting a strong relationship between lexical and grammatical skills, also in bilingual children and in children with atypical development.…”

One of the most popular and widely used parent report instruments for assessing early language acquisition is the MacArthur-Bates Communicative Development Inventories (MB-CDI). This study compares normative data of the Italian Words and Sentences complete form (WS-CF) and short form (WS-SF). The samples included 752 children for the WS-CF and 816 children for the WS-SF designed for children aged 18–36 months. The concordance between WS-SF and WS-CF is analyzed in a subgroup of 65 children. The results revealed strong correlations between WS-CF and WS-SF in both lexical and grammar skills as well as strong relationship between lexical and grammar skills. There was a high percentage agreement (97%) between the two forms for scores below the 10th percentile, suggesting that the two forms may be used interchangeably in order to describe vocabulary and grammatical development.

“…In response to the variation they found in their study, Deckers et al. (2016) recommended use of the International Classification of Functioning, Disability and Health for Children and Youth to create a profile of communication to determine which supports are needed for each child's unique constellation of body function, participation, activity, environmental and personal factors. We concur with this recommendation.…”

“…Moreover, as children with DS often have low speech intelligibility and intermittent hearing loss, augmenting spoken language with signed communication can be a useful support in a busy classroom, even for those who use largely spoken language (Faragher et al, 2020). In response to the variation they found in their study, Deckers et al (2016) recommended use of the International Classification of Functioning, Disability and Health for Children and Youth to create a profile of communication to determine which supports are needed for each child's unique constellation of body function, participation, activity, environmental and personal factors.

Background: Previous studies have explored the size and word type composition (nouns, predicates, etc.) of expressive vocabularies of preschool children with Down syndrome, both spoken and signed. Separately, overall preferences for modality of expression have also been explored. Aims: To extend previous findings by describing the relationships between expressive vocabulary size and both word type and modality of expression in the preschool period including changes to modality preference over time. Methods& Procedures: Mothers of 35 children with Down syndrome, aged 36-66 months and attending the same early intervention programme, completed a version -with both spoken word and sign options -of the New Zealand MacArthur-Bates Communicative Development Inventory (CDI): Words and Sentences. Most mothers completed the CDI on multiple occasions across the duration of the study. Completions (n = 114) were analysed cross-sectionally and longitudinally in terms of (1) word type relative to vocabulary size, (2) modality of expression relative to word type and vocabulary size, and (3) individual trajectories in vocabulary size and modality of expression. Outcomes & Results:(1) Word type relative to vocabulary size was similar to previous studies with a greater proportion of the SOCIAL words being present in the children's vocabularies throughout, followed by NOUNS, PREDICATES and CLOSED class words, with proportions converging as vocabulary sizes increase.(2) An initial spoken word preference for SOCIAL and CLOSED class words and sign preference for NOUNS and PREDICATES was found, with more spoken words in larger vocabularies overall. (3) Individual trajectories were highly variable and also revealed temporary points of regression in overall expressive vocabulary size in some children. Children who shifted from reliance on sign to predominantly spoken word expression did so at different ages and at different vocabulary sizes.

“…In Dutch clinical and educational practice, where the present study was conducted, sign supported Dutch (SSD), fingerspelling and key-word signing, are commonly used in young children with DS. As a result these children use manual sign systems as an important mode of communication (Deckers, Van Zaalen, Mens, Van Balkom, & Verhoeven, 2016a). The signs used in SSD stem are from the sign language of the Netherlands and are therefore actual signs and not just (deictic or representational) gestures.…”
