Pragmatic abilities in children with neurodevelopmental disorders: development of Pragmatic Abilities Questionnaire based on the Rasch rating scale model

Language abilities in children and adolescents with DLD and ADHD: A scoping review

PURPOSE

There is an emerging view that attention-deficit/hyperactivity disorder (ADHD) is marked by problems with language difficulties, an idea reinforced by the fact that ADHD is highly comorbid with developmental language disorder (DLD). This scoping review provides an overview of literature on language abilities in children with DLD and ADHD while highlighting similarities and differences.

METHOD

A comprehensive search was performed to examine the literature on language abilities in the two disorders, yielding a total of 18 articles that met the inclusion criteria for the present review. Qualitative summaries are provided based on the language domain assessed.

RESULTS

The current literature suggests children and adolescents with ADHD have better morphosyntax/grammar, general/core language abilities, receptive, and expressive abilities than those with DLD. Further, that performance is comparable on assessments of semantic and figurative language but varies by sample on assessments of phonological processing, syntax, narrative language, and vocabulary.

CONCLUSION

Evidence presented points to children and adolescents with DLD as having greater language difficulties compared to those with ADHD, but with some important caveats. Despite limitations related to the paucity of studies and inconsistencies in how the two types of disorders are identified, our review provides a necessary and vital step in better understanding the language profiles of these two highly prevalent childhood disorders. These findings are useful in optimizing language outcomes and treatment efficacy for children and adolescents with ADHD and DLD.

Developmental Language Disorder (DLD) and Autism Spectrum Disorder (ASD): similarities in pragmatic language abilities. A systematic review

Objective

Pragmatics can be defined as the appropriate use of language in social interactions. Children with Autism Spectrum Disorder (ASD) and children with Developmental Language Disorder (DLD) exhibit difficulties in pragmatic language (PL), but the nature and sources of these difficulties have not been fully investigated yet. The purpose of this paper is to critically review empirical literature on the PL of children with ASD as compared to that of children with DLD.

Materials and methods

Thirteen studies that met established inclusion criteria were identified and reviewed.

Results

Children with ASD and children with DLD demonstrated several similarities in PL. However, a lot of differences were observed and mainly children with ASD faced more profound difficulties than children with DLD, while PL may be a distinct marker between the two groups.

Conclusion

The differences observed in the language profiles of ASD and DLD show that even if there is an overlap in some domains, the PL abilities of children of both clinical populations are likely to be controlled by different mechanisms and therefore these differences in PL may be considered as a distinguishable feature between the two populations.

The Assessment of Early Pragmatic Development: A Study of the Reliability and Validity of the Language Use Inventory-Italian

Purpose Pragmatics is receiving much attention in both the fields of developmental and clinical psychology; however, there is a dearth of instruments to assess pragmatic abilities specifically among young toddler-age children. The aim of the current study was to test the psychometric properties of the Italian version of the Language Use Inventory (LUI), named the LUI-Italian, a parent report measure assessing pragmatic language development in children 18-47 months of age. Method Parents of Italian-speaking children who ranged in age between 18 and 47 months completed the LUI-Italian at T1 (N = 389) and 1 week later (N = 53). At T1, children were also administered the First Language Test (Test del Primo Linguaggio [TPL]), a direct measure of pragmatics, vocabulary, and syntax. Results Cronbach's alpha values were at or above acceptable levels. Factor analysis and test-retest confirmed the strong structure and reliability of the LUI-Italian. Some evidence for concurrent validity was found, as shown by associations between the LUI-Italian and the TPL. Conclusions The LUI-Italian demonstrated good psychometric properties relating to reliability, thus providing a sound basis for proceeding to a standardization study, and supporting cross-cultural comparison of pragmatic development and further exploration of profiles of pragmatic competence for children displaying language impairments or delay. Future studies need to further test concurrent, divergent, and predictive validity of the LUI-Italian.
