Associations of preschool reactive bed-sharing with sociodemographic factors, sleep disturbance, and psychopathology.

Objective: To advance understanding of early childhood bed-sharing and its clinical significance, we examined reactive bed-sharing rates, sociodemographic correlates, persistence, and concurrent and longitudinal associations with sleep disturbances and psychopathology.

Methods: Data from a representative cohort of 917 children (mean age 3.8 years) recruited from primary pediatric clinics in a Southeastern city for a preschool anxiety study were used.

Prevalence and Co-Occurrence of Developmental and Emotional-Behavioral Problems in Young Children.

Objective: A limited number of studies have estimated the prevalence of emotional-behavioral disorders among young children. None have assessed their co-occurrence with developmental delays using standardized assessment tools. Our objective was to estimate the prevalence of emotional-behavioral disorders and their co-occurrence with developmental delays among young children (2-5.

Comparative Accuracy of Developmental Screening Questionnaires.

Importance: Universal developmental screening is widely recommended, yet studies of the accuracy of commonly used questionnaires reveal mixed results, and previous comparisons of these questionnaires are hampered by important methodological differences across studies.

Objective: To compare the accuracy of 3 developmental screening instruments as standardized tests of developmental status.

Design, Setting, And Participants: This cross-sectional diagnostic accuracy study recruited consecutive parents in waiting rooms at 10 pediatric primary care offices in eastern Massachusetts between October 1, 2013, and January 31, 2017.

Effectiveness of a web-based protocol for the screening and phenotyping of individuals with Tourette syndrome for genetic studies.

Genome-wide association studies (GWAS) and other emerging technologies offer great promise for the identification of genetic risk factors for complex psychiatric disorders, yet such studies are constrained by the need for large sample sizes. Web-based collection offers a relatively untapped resource for increasing participant recruitment. Therefore, we developed and implemented a novel web-based screening and phenotyping protocol for genetic studies of Tourette syndrome (TS), a childhood-onset neuropsychiatric disorder characterized by motor and vocal tics.

Lost toy? Monsters under the bed? Contributions of temperament and family factors to early internalizing problems in boys and girls.

This study was designed to examine the contribution of multiple risk factors to early internalizing problems and to investigate whether family and ecological context moderated the association between child temperament and internalizing outcomes. A sample of 1,202 mothers of 2- and 3-year-old children completed a survey of child social-emotional functioning, family environment, and violence exposure. Child temperament, maternal affective symptoms, and family expressiveness were associated with child anxiety and depression problems.
