This study aimed to describe the behavioral profile of individuals with SYNGAP1-ID. Parents/carers of 30 individuals aged 3-18 years old with a diagnosis of SYNGAP1-ID and 21 typically developing individuals completed the Vineland-3 Adaptive Behavior Scale and the Child Behavior Checklist. We found that those with SYNGAP1-ID showed fewer adaptive…

This study was to determine the effectiveness of augmented reality on phoneme and word reading for three first-grade students with developmental delays and autism in a self-contained elementary school classroom. Effectiveness of the intervention was evaluated with a multiple probe across word sets research design. An augmented reality iPad app was…

Objective: This study aimed to determine the link between Parental Acceptance-Rejection (PAR) and empathy and self-compassion in mothers of children with intellectual and developmental disabilities (IDDs). Method: The sample consists of 161 mothers who received pre-school education with children diagnosed with IDDs in Iran. The parental…

Families of young children with intellectual and developmental disabilities (IDD) experience challenges that may be exacerbated by challenging behavior (CB) and a lack of specialized support services. While waiting for services, families must implement strategies on their own, while taking arduous steps to access supports to eventually meet their…

Examining peer relationships among young children with developmental disabilities in early childhood can increase their acceptance and well-being in education. This study focused on the peer relationships of preschool children with various developmental disabilities in inclusive settings involving the participation of five teachers and one…

Background: This study investigates the impact of behavior problems on stress that parents may experience due to raising children with intellectual and developmental disabilities, in relation to various child and parental characteristics. Method: 175 parents of children with developmental and/or intellectual disabilities and with behavior problems…

Restricted and repetitive behaviors (RRB) are observed in young children with intellectual and developmental delays or disabilities (DD) including autism spectrum disorders (ASD). Self-injurious behavior is often considered an extreme form of RRB, but the nature of the relation between SIB and other forms of RRBs is not completely understood.…

Social-emotional development is foundational to learning and has been linked to long-term academic, behavioral and mental health outcomes for children (i.e., Jones et al., 2015). In early childhood, social-emotional development is encouraged primarily through familial relationships. Children with developmental delays and disabilities (DD) are more…

Identifying infants at elevated likelihood for autism and other developmental differences in the first year of life remains a significant challenge. This study explored associations between behavioral differences in infancy and developmental outcomes in toddlerhood. We conducted a secondary data analysis of 256 infants with an older autistic…

Background: Limited data exist on problematic sexual behaviour (PSB) in youth with developmental disabilities in South Korea. Method: Sixty-one parents of children with intellectual disabilities or autism spectrum disorder (aged 13-30) reported children's PSB and emotional, behavioural, cognitive, and interpersonal factors. The frequency of PSB in…

To gain an understanding of how caregivers' perceptions are influenced by their cultural backgrounds, we conducted semi-structured interviews with 19 Korean caregivers (Korean American = 10 caregivers; Korean caregivers in Korea…

Purpose: The present study was designed to investigate persistence in preschool children with developmental language disorder (DLD) compared to similar-age peers with typical language (TL) on tasks designed to be moderately challenging, yet equivalent in difficulty for both groups. Method: Sixteen preschool-age children with DLD were matched to 16…

This study aimed to evaluate Promoting Reciprocal Relationships with Flexibility, Coaching, and Teaching (PRRFCT Match), a parent-mediated naturalistic developmental behavioral intervention package. An expansion from an earlier pilot study (see Kunze et al., 2021), PRRFCT Match incorporates virtual coaching between a novice coach and parent to…

Purpose: The purpose of this study was to examine feedback processing within the context of probabilistic learning in children with and without developmental language disorder (DLD). Method: The probabilistic category learning task required 28 children ages 8-13 years old to classify novel cartoon animals that differed in five binary features into…

Little is known about the attributional patterns of caregivers of autistic children, particularly in relation to caregivers of children with other developmental or behavioral disorders. This study examined differences in caregiver attributions of child behavior between three groups: toddlers with (1) Autism spectrum disorder (ASD) or ASD concerns;…
