3q29 deletion syndrome (3q29del) is associated with a significantly increased risk for neurodevelopmental and neuropsychiatric disorders. However, the full spectrum of behavioral phenotypes associated with 3q29del is still evolving. Individuals with 3q29del (n = 96, 60.42% male) or their guardian completed the Achenbach Child or Adult Behavior…

This study examines the reliability of parental concern (PC) as an indicator for mental disorders in preschool-aged children in a clinical setting, aiming to establish sensitivity and specificity, evaluate PC's predictive value for specific diagnoses, and explore the influence of child age on predictions. The sample comprises 574 children referred…

We analyzed CBCL/1½-5 Pervasive Developmental Problems (DSM-PDP) scores in 3- to 5-year-olds from the Study to Explore Early Development (SEED), a multi-site case control study, with the objective to discriminate children with ASD (N = 656) from children with Developmental Delay (DD) (N = 646), children with Developmental Delay (DD) plus ASD…

Occupational therapists treat children with sensory processing and behavioral concerns, however, little information exists on how these issues affect parent participation. This pilot study examined the sensory processing and behaviors of toddlers with developmental delays and correlated these with parents' perceived ability to participate in…

Executive functioning abilities have been associated with important behaviors such as adaptive skills and cognitive abilities in children with and without disabilities. Executive functioning has primarily been measured as a strong predictor of later abilities in children with neurodevelopmental disabilities, such as attention-deficit/…

To test the Child Behavior Checklist's (CBCL/1½-5) ability to screen for autism spectrum disorders (ASD), we studied Korean preschoolers: 46 with ASD, 111 with developmental delay (DD), 71 with other psychiatric disorders (OPD), and 228 non-referred (NR). The ASD group scored significantly higher than the other groups on the Withdrawn and…

Early indicators of academic risk were used to predict the academic skills, socioemotional functioning, and receipt of special education services at age 10 among children from low-income families who participated in the Early Head Start Research and Evaluation Project. Pairwise comparison of academic skills and socioemotional functioning among…

This study investigated parent and teacher ratings of behavior problems in children with and without intellectual disabilities at three time points over the course of 9 years. The group of children with intellectual disabilities (IDs) had higher behavior problem ratings than the group of children with no IDs (NIDs) across the three time points.…

The current study evaluated the play behaviors of children with disabilities (e.g., developmental delays, specific language impairment) who participated in a social communication intervention targeting skills such as initiations, responses, name use, proximity, and turn-taking. Three children who were enrolled in an inclusive classroom met the…

Objective: This study investigated the association between preschool children's sleep patterns measured by actigraphy and parent-reported hyperactivity symptoms. Many previous studies have reported sleep problems in children with attention deficit hyperactivity disorder (ADHD)-like symptoms. Methods: This study examined a cross-sectional sample of…

Background: This study assessed the co-occurrence of cognitive problems and difficult temperament characteristics in children aged 3 to 5 years exhibiting aggressive behavior. Methods: Thirty-one children with high ratings on the Aggressive Behavior subscale of the Achenbach Child Behavior Checklist or Teacher Report Form were recruited from a…

A growing body of evidence indicates that for some children, early incidences of challenging behaviors are predictors of later difficulties. These incidences of challenging behaviors may predict mental health issues, social adjustment issues and/or increased challenging behaviors that will impede school success and impact transition to adult life…

Current widespread use of the same youth assessment measures and scales across different nations assumes that youth psychopathology syndromes do not differ meaningfully across nations. By contrast, the authors' syndromal sensitivity model posits 3 processes through which cultural differences can lead to cross-national differences in…

This study compared behavioral presentation of toddlers with autistic spectrum disorders (ASD) and toddlers with global developmental delay (DD) or developmental language disorder (DLD) who display some characteristics of ASD using the diagnostic algorithm items from the Autism Diagnostic Observation Schedule, Generic (ADOS), the Childhood Autism…

Background: While parenting behaviours have direct effects on children's behavioural outcomes, other, more distal factors also may be shaping the way a mother handles parenting responsibilities. Dispositional factors are likely to be a major influence in determining how one parents. Although researchers have studied the relationships among…
