The disorder is quite heterogeneous, can be very debilitating, and has a lifelong course. The general consensus among researchers, therefore, is that intervention should start at a very early age as a means of enhancing prognosis. The linchpin of early treatment is early detection and diagnosis. As a result of this recognized goal, psychiatrists and psychologists have been engaged in intensive efforts to develop methodologies and methods which will allow for the identification of autism at two years of age or younger. The current review focuses on research for early detection and diagnosis, relevant issues in identifying the disorder, and available assessment methods and instruments for making a diagnosis. Recommendations for future research are provided.

An examination of challenging behaviors in autistic disorder versus pervasive developmental disorder not otherwise specified: Significant differences and gender effects / Alison M. KOZLOWSKI in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)

Unfortunately, due to its absence as a criterion for diagnosis in the DSM-IV-TR, little attention has been paid to the endorsement rates of such behaviors. However, a recently developed measure to assist in the diagnosis of infants and toddlers with autism and PDD-NOS – the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT) – has included a section designated for just this reason. This study used the BISCUIT to assess for significant differences in the endorsement rates of challenging behaviors between infants and toddlers with autism versus PDD-NOS as well as for significant differences between genders. There were significant differences between the diagnostic groups in endorsement rates of challenging behaviors as a whole, as well as among many specific behavior items. No significant differences between genders in endorsement rates of challenging behaviors were found. The implications of these findings are discussed.

An examination of the relationship between communication and socialization deficits in children with autism and PDD-NOS / Megan A. HATTIER in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)

As the onset of these features occurs at a very young age, early detection is of the utmost importance. In an attempt to better clarify the behavioral presentation of communication and socialization deficits to aid in early assessment and intervention, impairments in these areas were examined among infants and toddlers (17–36 months) with Autistic Disorder (AD), Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), and non-ASD related developmental delay. The Baby and Infant Screen for Children with aUtIsm Traits-Part1 (BISCUIT-Part1) and the Battelle Developmental Inventory, 2nd Edition (BDI-2) were utilized to examine communication and socialization levels, respectively, among these groups. All groups significantly differed on level of socialization impairment with the Autism group displaying the greatest impairment and the non-ASD related developmental delay group evincing the least impairment. In regards to communication deficits, the non-ASD related developmentally delayed group differed significantly in comparison to the Autism and PDD-NOS groups; however, no significant differences were found between children with AD and PDD-NOS. While communication and socialization impairments were found to significantly correlate for all participants with the exception of those with PDD-NOS, these correlations were not found to significantly differ from one another across groups. The implications, limitations, and future directions of these results are discussed.

An examination of the reliability of a new observation measure for autism spectrum disorders: The autism spectrum disorder observation for children / Daniene NEAL in Research in Autism Spectrum Disorders, 7-1 (January 2013)

MATSON, Auteur ; Brian C. BELVA, Auteur Année de publication : 2013 Article en page(s) : p.29-34 Langues : Anglais (eng) Mots-clés : ASD-OC  Autism spectrum disorder  Reliability  Assessment Index. décimale : PER Périodiques Résumé : The autism spectrum disorder observation for children (ASD-OC) is a newly created 54-item observation measure for autism spectrum disorders (ASD). Due to the fact that many of the ASD observation measures currently available do not have established psychometric properties and require extensive time and training to administer, the ASD-OC seeks to address these issues. The purpose of this initial study was to investigate the reliability of the ASD-OC. The measure was administered to a sample of 114 children as part of an outpatient evaluation. In a subset of the sample, 26 children were rated by two independent clinicians after the same session. Interrater reliability was calculated using intraclass coefficients (ICC). Five items were removed after this interrater reliability analysis given poor reliability coefficients less than .40. Mean interrater reliability for each of the 49 retained items was good (i.e., .73). Interrater reliability for the scale as a whole was excellent (i.e., ICC = .96). Item analysis and internal consistency were investigated in the total sample (n = 114). Four items were removed from the scale because of little to no variance in scores. Forty-five items remained on the scale. The internal consistency of the ASD-OC as measured by Cronbach's alpha was excellent at .96. The ASD-OC proved to be a promising measure with robust reliability.

In the current study, toddlers (i.e., 17–37 months of age) with diagnoses of either AD (N = 159) or PDD-NOS (N = 154) were compared to atypically developing toddlers who did not meet criteria for an autism spectrum disorder (N = 200). Results indicated an overall pattern whereby toddlers with AD had more severe anxious and avoidant symptoms than either toddlers with PDD-NOS or controls. Further, toddlers with PDD-NOS were significantly more severe than controls. Additional analyses examining specific differences between the groups on anxious and avoidant items were conducted as well. Overall, toddlers with AD appear to have more severe anxiety than either those with PDD-NOS or controls, who did not differ on many items.
