This study investigated the Infant Behavior Record (IBR) as an observer-rated measure of temperament. The aim was to determine whether the IBR and a parent-rated measure of temperament were comparably associated with children's performance on laboratory tasks and with a measure of the home environment. We found several significant associations…

This article presents a description of the Vineland Adaptive Behaviour Scales, Third Edition (Vineland-3; Sparrow, Cicchetti, & Saulnier, 2016), published by Pearson, which is a newly updated individually administered measure of adaptive functioning for individuals from birth to age 90. Primarily used in clinical, psychoeducational, and…

High quality educational settings play a crucial role in preparing a child to enter kindergarten, but little work has explored how outdoor play and complex physical activity outside school and childcare settings promote school readiness among preschoolers. To address this gap, the present study explored connections among school readiness with…

This study presents an independent replication and extension of psychometric evidence supporting the "Theory of Mind Inventory" ("ToMI"). Parents of 20 children with ASD (4; 1-6; 7 years; months) and 20 with typical development (3; 1-6; 5), rated their child's theory of mind abilities in everyday situations. Other parent report…

Sensory symptoms are prevalent in autism spectrum disorder but little is known about the early developmental patterns of these symptoms. This study examined the development of sensory symptoms and the relationship between sensory symptoms and adaptive functioning during early childhood. Three groups of children were followed across three time…

The measurement of treatment integrity is critical to evaluate the efficacy and effectiveness of evidence-based programs (EBPs) designed to improve the developmental outcomes of young children at risk of emotional/behavioral disorders. Unfortunately, the science of treatment integrity measurement lags behind the development and evaluation of EBP…

This study investigates the relationship between young children's habitual computer use and influencing variables on socio-emotional development. The participants were 179 five-year-old children. The Internet Addiction Scale for Young Children (IASYC) was used to identify children with high and low levels of habituation to computer use. The data…

Seventy-two children (ages 23-148 months) referred to an autism center in the Netherlands were administered the Psychoeducational Profile (PEP) and the Handicaps Behaviour and Skills Schedule (HBS). The correlation between the two instruments was higher than expected, and internal consistency of the subscales of the PEP and the HBS was…

Developmental psychologists have not traditionally documented the psychometric properties of their observational instruments, partly because such concepts as reliability and validity are associated mainly with paper-and-pencil tests. A multitrait-multimethod correlation matrix (MTMM) was presented as a useful method for the psychometric evaluation…

As part of the national Head Start Planned Variation Study, this study used a relatively small sample in an intensive evaluation of program implementation in one field community using the Tucson Early Education Model (TEEM). A modified Solomon four-group research design formed the organization framework. Evaluation of six TEEM classrooms and two…
