Are language features and emotion regulation related to maternal depression in autism and language delay?

Background: Language and communication are very important in child social, emotional and cognitive development. Delay in language is usually the first complaint for children diagnosed with autism spectrum disorder (ASD) or developmental language delay (DLD). This study evaluated language features and emotion regulation skills in children diagnosed with ASD and DLD and their association with maternal depression.

Method: The sample consisted of children aged 24-54 months diagnosed with ASD (n = 31), or with DLD (n = 45), and 52 healthy controls. The Test of Early Language Development (TELD-3) was used to evaluate language profiles, and the beck depression inventory (BDI) was used to examine maternal depression. Children's emotion regulation skills were evaluated using the emotion regulation checklist.

Results: Children with DLD had a significantly higher developmental age, were linguistically more developed and had better emotion regulation than the ASD group. All domains of language on TELD-3 except expressive syntax were more developed in DLD. Maternal BDI score did not differ significantly between DLD and ASD. Both of these disorders were not associated with maternal depression.

Conclusion: Children with DLD were less impaired than children with ASD, both in terms of language and in emotion regulation.
