We explored sex differences in diagnostic categories, clinical symptoms and adaptive behavior of persons with autism spectrum disorders, as well as sex-specific correlations of clinical and adaptive caracteristics. The study involved 108 patients (83 males, 6.73 ± 4.33 years old) diagnosed with autism spectrum disorders (ASD). Assessment included ADI-R and Vineland Adaptive Behavior Scale II. M...

BACKGROUND: The purpose of the current study was to evaluate the relationships among sleep problems and daytime behaviors in a large, well-defined cohort of children with autism spectrum disorder (ASD). METHODS: Out of a registry population of 3452 children with ASDs, a subset of 1193 children aged 4 to 10 years of age from 14 centers across the country was used to evaluate the relationship bet...

AIM To determine if the benefit of early confirmation of permanent childhood hearing impairment (PCHI) on children's receptive language development is associated with fewer behavioural problems. METHOD Follow-up of a total population cohort of 120 children with PCHI of moderate or greater severity (≥ 40 decibels relative to hearing threshold level) (67 males, 53 females; mean age 7 y 11 mo, r...

OBJECTIVE To examine longitudinally the adaptive behavior patterns in fragile X syndrome. METHOD Caregivers of 275 children and adolescents with fragile X syndrome and 225 typically developing children and adolescents (2-18 years) were interviewed with the Vineland Adaptive Behavior Scales every 2 to 4 years as part of a prospective longitudinal study. RESULTS Standard scores of adaptive be...

Purpose: The Vineland-II is a standardized norm-referenced assessment tool that can be used for: • measuring an individual’s daily functioning • measuring deficits in adaptive behavior • clinical diagnosis of autism spectrum disorders, genetic disorders, developmental • delays, emotional and behavioral disturbances as well as other mental, physical or • injury related conditions • developmental...

This study explored whether young children with Down syndrome show praxis deficits that impact activities of daily living, and whether these deficits are specific to Down syndrome. We compared the performance of young children with Down syndrome, a mental age-matched group of children with developmental disabilities of mixed or unknown etiologies, and a group of typically developing infants and...

OBJECTIVE To establish construct validity of the Capacity Profile, a method to comprehensively classify additional care needs in five domains of body functions (physical health, motor, sensory, mental, voice and speech functions), in adolescents with non-progressive, permanent conditions such as cerebral palsy. DESIGN Cross-sectional study. SUBJECTS Ninety-four adolescents with cerebral pal...

OBJECTIVE The survival of very low birth weight infants has increased markedly in recent years. Unfortunately, the prevalence of significant and lifelong motor, cognitive, and behavioral dysfunction has remained a major problem confronting these children. The objective of this study was to perform screening tests for early autistic features in children with a history of very low birth weight an...

We examined the course of repetitive behavior and restricted interests (RBRI) in children with and without Down syndrome (DS) over a two-year time period. Forty-two typically-developing children and 43 persons with DS represented two mental age (MA) levels: "younger" 2-4 years; "older" 5-11 years. For typically developing younger children some aspects of RBRI increased from Time 1 to Time 2. In...
