Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

Purpose: The lack of appropriate assessments affects populations presumed to be most at risk for speech and language concerns, one of them being children with a history of preterm birth. This study aims to examine whether cultural bias is present in two currently available language tests for Black children under 3 years of age: the Communication…

The Communication and Symbolic Behavior Scales Developmental Profile (CSBS DP) is a valid and reliable screening tool for detecting language delay in children. However, it has not been translated into the Indonesian language. This study aimed to determine the validity and internal consistency of the Indonesian-translated CSBS DP as a screening…

CDKL5 deficiency disorder (CDD) results in early-onset epilepsy and lifelong cognitive and motor impairments. With no validated measure for communication in CDD, this study evaluated the psychometric properties of the Communication and Symbolic Behavior Scales-Developmental Profile Infant Toddler Checklist (CSBS-DP ITC). Caregivers (n = 150;…

Robust evidence supports the efficacy of early autism intervention. Despite broad consensus that earlier intervention leads to better outcomes, evidence for this has been limited to correlational studies. This study examined timing effects of the Early Social Interaction (ESI) model, a parent-implemented intervention, using a complete crossover…

Delays in autism spectrum disorder identification/services could impact developmental outcomes. Although trends are encouraging, children from historically underrepresented minority backgrounds are often identified later and have reduced engagement in care. It is unclear if disparities exist throughout the screen-evaluate-treat chain, or if early…

Background: As delays or disorders in early language and communication are the most prevalent symptom in children with disabilities, early screening is crucial to promote prevention, early diagnosis, and intervention. However, to the best of our knowledge, no screening tool is available for the joint assessment of early language and social…

An early diagnosis of autism spectrum disorder (ASD) can improve outcomes for children and assist families in accessing services. Part C providers are often tasked with screening for ASD. The purpose of this study was to survey Part C providers nationwide to understand their ASD screening practices and training needs and extend a survey conducted…

One of the earliest indicators of autism spectrum disorder (ASD) is delay in language and social communication. Despite consensus on the benefits of earlier diagnosis and intervention, our understanding of the language growth of children with ASD during the first years of life remains limited. Therefore, this study compared communication growth…

Background and Aims: Individuals with fragile X syndrome (FXS) characteristically struggle with language and communication throughout the life course, but there is limited research on the development of communication before 24 months. The purpose of this study is to describe the early communication of infants and toddlers with FXS using the…
