The effectiveness of education and upbringing of children with hearing loss who are placed in special and mixed groups remains an important issue. The study aims to establish mixed groups consisting of both healthy children and children with hearing loss, and subsequently evaluate and compare their cognitive and mental development across different…

The development of copying behaviours of a group of infants from 9 to 15 months of age is analysed. These behaviours are classified according to their type (mimetic or imitated) and function (instrumental, social or hybrid). The function of the behaviours is derived from observable indicators linked to dyadic interaction. Mimetic behaviours are…

This study investigated verbal imitation from a multimodal point of view, considering the mutual influence of children's and adults' participation. Sixteen Spanish-speaking children were observed longitudinally at 21, 24, and 30 months of age in natural settings. We analyzed the multimodal characteristics of children's and adults' repetitions,…

Because early intervention often leads to the best outcomes in children with autism spectrum disorder (ASD), it is important that these children are identified as early as possible. Therefore, exploration of tools that could be used to identify at-risk children at an early age is needed. Such a tool could assist health professionals and their…

Autism spectrum disorder (ASD) frequently co-occurs with additional symptoms of psychopathology and challenging behaviors. While aggressive behaviors are often associated with attention deficits and hyperactivity in children with ASD, there is limited research on the impact that inattention/impulsivity and aggressive behaviors have on the…

This study is a systematic review designed to identify the instruments most frequently used to evaluate children's development, describe their operational and psychometric characteristics and determine which are the most accurate. We carried out a systematic search of the online databases PsycINFO and PubMed Central using the descriptors…

This study aimed to replicate and extend findings from the only known study that has conducted latent profile analysis of developmental profiles, measured by the Battelle Developmental Inventory, for children in Early Intervention (EI). Children (N = 57,966) who were enrolled in Massachusetts EI sites between 2011 and 2019 and completed a Battelle…

Purpose: Chromosome 16p11.2 deletion syndrome (OMIM #611913) is a rare genetic condition resulting from the partial deletion of approximately 35 genes located at Chromosome 16. Affected people exhibit a variable clinical profile, featuring mild dysmorphisms, motor problems, developmental delay, mild intellectual disability (ID), socialization…

Identification of problems with socioemotional functioning is an important task in early childhood, particularly for children in early intervention (EI). However, socioemotional concerns raised by families may be under-identified in practice. In accordance with Division for Early Childhood (DEC) recommended practices, Part C providers could…

Researchers seeking to make valid conclusions about engagement for young children with autism spectrum disorder (ASD) must first determine the reliability of estimates obtained across the conditions sampled. Working from that premise, we conducted a secondary data analysis of shared book readings between caregivers and their children with ASD,…

Currently, Developmental scales for children aged 0-6 years are a particularly valuable resource for assessing developmental milestones in children. Most scales are developed based on a broad conceptual framework, and their metric validation is insufficient and of low quality. The aim of this systematic review is to analyse the psychometric…

Background: Using progress monitoring data to make effective and timely decisions in early intervention (EI) requires high quality assessment. Infant/toddler individual growth and development indicators (I/T IGDIs) have been developed to be brief, reliable and engaging progress monitoring tools that are sensitive to change over short time periods…

A growing body of research suggests that symptoms of autism spectrum disorder (ASD) may present differently in males and females. This study examined gender differences in ASD symptoms and developmental functioning, using the "Baby and Infant Screen for Children with aUtism Traits, Part 1" (BISCUIT-Part 1) and the "Battelle…

In the United States, early intervention (EI) programs under Part C of the Individuals with Disabilities Education Act serve thousands of infants and toddlers with or at risk for developmental delays. Despite this, few studies have investigated the developmental progress and outcomes of children served, especially in relation to the heterogeneity…

Early intervention for children with developmental delays or disabilities may prevent future need for special education services. The Individuals with Disabilities Education Act (IDEA) allows each state to establish criteria for eligibility for early intervention services for children younger than 3 years old (Part C) and special education…
