Children with a history of behaviorally inhibited (BI) temperament face a heightened risk for anxiety disorders and often use control strategies that are less planful. Although these relations have been observed concurrently in early childhood, middle childhood, and adolescence, few studies leverage longitudinal data to examine long-term…

Purpose: Early detection of language delays is essential, as language is key for academic outcomes, well-being, and societal participation. Previous studies have focused on undetected delays in young children. Much less is known about referrals at older ages. In this study, we aimed to (a) establish how many children are referred at toddler age…

Cross-sectional studies have shown that greater friendship satisfaction in adulthood is associated with many positive outcomes (Chopik, 2017; Gillespie, Frederick, et al., 2015). However, the developmental antecedents of satisfaction with close friends in adulthood have not been examined using prospective data. We do not know, for example, whether…

There is scant empirical work on associations between current and past cannabis use in parents of young children. As recreational cannabis use is now legal in nearly half of states in the U.S., cannabis use is becoming more ubiquitous. In the current study, parents of toddler and pre-school age children were randomly assigned to participate in an…

Extensive evidence and theory suggest that the development of motor skills during infancy and early childhood initiates a "developmental cascade" for cognitive abilities, such as reading and math. Motor skills are closely connected with the development of spatial cognition, an ability that supports deductive reasoning. Despite the…

The Autism Classification System of Functioning: Social Communication (ACSF) describes social communication functioning levels. First developed for preschoolers with ASD, this study tests an expanded age range (2-to-18 years). The ACFS rates the child's typical and best (i.e., capacity) performance. Qualitative methods tested parent and clinician…

The annual National Deafblind Child Count is the world's first and longest-running count of children who are deafblind. Begun in 1986 on behalf of the U.S. Department of Education, it represents a collaborative effort between the National Center on Deafblindness (NCDB) and state deafblind projects throughout the country, including those in the…

Primary attachment plays a fundamental role in children's social and emotional development and psychological well-being. Secure attachment correlates strongly with better social competence, self-regulation, well-being and school achievement. There is no full agreement among researchers investigating attachment as to what extent primary attachment…

This study conducted two meta-analyses to synthesize the association between children's language skills and two broad-band dimensions of psychopathology: internalizing and externalizing. Pooled estimates across 139 samples (externalizing k = 105; internalizing k = 90) and 147,305 participants (age range: 2-17 years old; mean % males: 53.75; mean %…

The annual National Deaf-Blind Child Count is the world's first and longest-running count of children who are deaf-blind. Begun in 1986 on behalf of the U.S. Department of Education, it represents a collaborative effort between the National Center on Deaf-Blindness (NCDB) and state deaf-blind projects throughout the country, including those in the…

Developmental scholars, parents, and policymakers alike have long heralded the opening years of life as disproportionately influential. Recent work on adolescence has revealed, however, greater influence of these later years--but without considering how experience during these two periods interact. We address this issue by studying adverse…

Autistic children have a high prevalence of co-occurring mental health, developmental/behavioral, and medical conditions, but research on sex/gender differences has been mixed. We used Florida healthcare claims data to characterize sex differences (female/male) in co-occurring conditions among autistic children ages 1-21 (N = 83,500). After…

The estimated number of forcibly displaced persons around the globe is at a record high--nearly 70.8 million (UNHCR 2019)--75 percent of whom are women and children. This includes 34 million adolescent girls and young women, who are among the groups with the highest risk for health concerns. Indeed, many of the countries with the worst maternal…
