Early detection and intervention is essential for children with autism spectrum disorders (ASD). Therefore, we examined the reliability and validity of the Japanese version of the Modified Checklist for autism in toddlers (M-CHAT), a 23-item, yes-no questionnaire regarding early autistic symptoms completed by parents of children at 18-24 months of…

The psychometric properties of the Infant-Toddler Environment Rating Scale-Revised Edition (ITERS-R) were examined using 153 classrooms from child-care centers where resources were tied to center performance. An exploratory factor analysis revealed that the scale measures one global aspect of quality. To decrease redundancy, subsets of items were…

This study examined 3-year-old children who were classified as hyperactive (HYP), oppositional-defiant (OD), hyperactive and oppositional defiant (HYP/OD), and non-problem based on mothers' reports of behavior. Using fathers', teachers', and observers' ratings of children's behavior, concurrent validity was excellent for the HYP/OD group, moderate…

The quality of care in infant and toddler classrooms was compared across inclusive (n=64) and noninclusive classrooms (n=400). Quality was measured using the Infant/Toddler Environment Rating Scale-Revised (ITERS-R). An exploratory and confirmatory factor analysis revealed four distinct dimensions of quality within the ITERS-R. Inclusive…

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…

The effects of modifying the structural quality components of inclusive classrooms on material engagement among toddlers (18-36 months) with and without disabilities were evaluated. Initially, three classrooms were evaluated using items that addressed structural quality from the Infant/Toddler Environment Rating Scale, the National Association for…

This study investigated whether specific behaviors observed in 30 month-old low-birthweight children are predictive of diagnosis of attention-deficit/hyperactivity disorder (ADHD) and school difficulties at age 8. Videotapes of 571 participants were coded using the Attention-Deficit Hyperactivity Disorder Observational Rating Scale (ADHD-ORS).…

Four tenets of dynamic systems theory related to motor development in infants are identified: coupling of perception and action; development of adaptable and functional movement synergies; phase shifts in which new movement patterns are explored and selected; and identification of the constraining and facilitating forces of motor development. Four…

The early childhood literature has acknowledged the need for culturally competent child care professionals. Based on Sue's (1981) tri-dimensional model, the Infant and Toddler Caregiver Cultural Rating Scale (ITCCRS) was created to assess 109 child care providers' cultural competence and the demographic correlates of that competence. Scores fell…
