Recent studies of autism diagnosis in New Zealand have revealed inconsistent implementation of best practice standards in autism assessment and high rates of parental dissatisfaction with the diagnostic process. These findings have arisen despite the development and dissemination of the New Zealand Autism Spectrum Disorder Guideline (the…

The newest edition of the "Diagnostic and Statistical Manual of Mental Disorders" (5th ed., DSM-5) introduced substantial changes to the diagnostic criteria for autism spectrum disorder, including new severity level ratings for social communication and restricted and repetitive behavior domains. The purpose of this study was to evaluate…

In order to shed more light on why referred girls are less likely to be diagnosed with autism spectrum disorder than boys, this study examined whether behavioral characteristics influence the probability of an autism spectrum disorder diagnosis differently in girls versus boys derived from a multicenter sample of consecutively referred children…

Literature on "Thin Slice" ratings indicates that a number of personality characteristics and behaviors can be accurately predicted by ratings of very short segments (<5?min) of behavior. This study examined the utility of Thin Slice ratings of young children with autism spectrum disorder for predicting developmental skills and…

We contrasted Behavior Assessment System for Children, Second Edition--Parent Rating Scales--Preschool Form (BASC-2 PRS-P) parent ratings for 242 (52% African American; 39% White) preschool-aged children from three diagnostic groups: autism spectrum disorder (ASD), intellectual disability (ID), and ASD and ID (ASD/ID). Across diagnostic groups,…

The prevalence of autism spectrum disorder (ASD) in many genetic disorders is well documented but not as yet in Mucopolysaccharidosis type III (MPS III). MPS III is a recessively inherited metabolic disorder and evidence suggests that symptoms of ASD present in MPS III. This systematic review examined the extant literature on the symptoms of ASD…

Given that early caregiver concerns may be different for children who go on to receive a diagnosis of autism spectrum disorder versus another developmental disability, early caregiver concerns may differ for girls. Using a community-based sample of children (n = 241), we examined the extent to which gender differences may be related to caregiver…

Aim: To explore whether active head lifting from supine (AHLS) in early infancy is associated with cognitive outcome in the second year of life. Method: The presence of AHLS was always recorded in the notes of infants admitted to our tertiary neonatal intensive care unit. Random sampling was used to pair infants with AHLS with two comparison…

Relationships between the home environment and early developmental outcomes were examined in 166 children born very preterm in one tertiary maternity hospital to explore whether a more optimal home environment could promote resilience. In particular, we explored whether this effect was apparent over and above social risk and children's biological…

Aim: To investigate the predictive value of motor testing at 1 year for motor and mental outcome at 2 years after perinatal hypoxic-ischaemic encephalopathy (HIE) in term neonates. Method: Motor and mental outcome at 2 years was assessed with the Bayley Scales of Infant Development, 2nd edition (BSID-II) in 32 surviving children (20 males, 12…

The repeated psychological assessment of 41 high-risk infants during the first 2 years of life using the Mental Scale of the Bayley Scales of Infant Development was investigated. Analyses indicated that the infants' cognitive functioning remained fairly stable over the 2 years, particularly from age 6 months on. (Author/JDD)

This three-part study of early identification of developmental deficiencies in high risk infants was undertaken to determine whether infant performance can be predicted from neonatal and developmental criteria. Part I of the study began in 1977 and used 284 high risk infants as subjects. Part II was initiated in 1978. Subjects were 14 full-term,…

Eighty at-risk infants were administered the Mental and Motor Scales of the Bayley Scales of Infant Development at 6 and 12 months of age. Test-retest reliability scores of .71 on the Mental Scale and .69 on the Motor Scale were obtained. (Author/JDD)

The concurrent validity of the Battelle Developmental Inventory was explored by correlating Battelle results with scores from the Bayley Scales in 30 infants with known or suspected disabilities. Both the pattern and strength of the obtained correlations support use of the Battelle to measure development in infants with handicaps. (Author/JDD)

The primary purpose of this study was to examine uneven early development in premature infants. A multiple regression analysis was performed in which birth weight, length of gestation, length of assisted feeding, and length of ventilation were used to predict the descrepancy between a child's Psychomotor and Mental Scale scores on the Bayley…
