Defining characteristics for young children meeting cutoff on the modified checklist for autism in toddlers / Alison M. KOZLOWSKI in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)

WORLEY, Auteur ; Megan SIPES, Auteur ; Max HOROVITZ, Auteur Année de publication : 2012 Article en page(s) : p.472-479 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Early diagnosis of Autism Spectrum Disorders (ASDs) is crucial so that early intervention services, which have been found to best alleviate symptoms of ASD in children, can be implemented. Currently, the Modified Checklist for Autism in Toddlers (M-CHAT) and the Baby and Infant Screen for Children with aUtIsm Traits-Part 1 (BISCUIT-Part 1) are the most widely researched ASD measures in early childhood. However, the M-CHAT provides many false positive results as it is solely used as a screening instrument as opposed to a diagnostic measure, while the BISCUIT-Part 1 appears to have more diagnostic fidelity. The current study examined 243 toddlers who failed the M-CHAT screener and were therefore referred for further evaluation. Upon further evaluation, 141 of the toddlers were diagnosed with an ASD while the remaining 102 were not. Characteristics differentiating these two groups on the M-CHAT, BISCUIT-Part 1, and Battelle Developmental Inventory, Second Edition (BDI-II) were examined with analyses supporting the hypotheses that children in the ASD group had higher M-CHAT and BISCUIT-Part 1 scores in conjunction with lower BDI-II scores. Based on these results, the incremental predictive validity of the M-CHAT was assessed; the BISCUIT-Part 1 was found to be more accurate in arriving at ASD diagnoses. The implications of these findings are discussed.

Reliability of the Matson Evaluation of Social Skills with Youngsters (MESSY) for children with Autism Spectrum Disorders / Johnny L. MATSON in Research in Autism Spectrum Disorders, 7-2 (February 2013)

In Study 1, 114 children with ASD (Autistic Disorder, Asperger's Syndrome, or Pervasive Developmental Disorder ? Not Otherwise Specified) were assessed using the MESSY. Participants ranged in age from 2 to 16 years. Study 1 found excellent internal consistency, and split half reliability. Using MESSY scores from two caregivers of 33 children, Study 2 found that the MESSY demonstrated moderate to high inter-rater reliability. As such, this study established the internal and inter-rater reliability of the MESSY for use among children with ASD.

The Baby and Infant Screen for Children with aUtIsm Traits-Part 3: The development of age-based scoring procedures / Max HOROVITZ in Research in Autism Spectrum Disorders, 7-11 (November 2013)

Separate age-based cutoffs were developed for those with an autism spectrum disorder (ASD) and those with non-ASD related developmental delays, using the standard deviation from the mean method. The sample consisted of 3022 infants and toddlers and their parents. As age increased in those with ASD, higher cutoff scores were required. Less variation was seen in the cutoff scores established for those with non-ASD related delays. The findings suggest that as children with ASD grow older, challenging behaviors become more frequent and severe. Additionally, they become easier to detect in comparison to same-aged peers. The implications of these results are discussed.

A two-way analysis of covariance was conducted with gender and diagnosis entered as independent variables, age at assessment entered as a covariate, and age of parents’ first concerns entered as the dependent variable. The average age of parents’ first concerns was significantly younger for females when compared to males. Additionally, the age of parents’ first concerns was significantly younger for toddlers with ASD when compared to toddlers with atypical development. No significant interaction was found.

The relationship between symptoms of autism spectrum disorders and psychotropic medication use in infants and toddlers / Max HOROVITZ in Research in Autism Spectrum Disorders, 6-4 (October-December 2012)

Participants in the current study were placed into one of four groups: ASD on psychotropic medications (N = 33), ASD off psychotropic medications (N = 45), atypically developing on psychotropic medications (N = 30) and atypically developing off psychotropic medications (N = 45). Severity of autistic symptoms were compared between the groups based on total scores on the Baby and Infant Screen for Children with aUtIsm Traits, Part 1(BISCUIT Part-1). Toddlers with ASD on psychotropic medications had significantly higher ratings than any other group. No such relationship was found within the atypically developing group. The results suggest a relationship between psychotropic medication use and severity of autistic symptoms in infants and toddlers. Implications of these results are discussed.
