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.

Anxiety symptoms across the lifespan in people diagnosed with Autistic Disorder / Thompson E. III DAVIS in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)

However, to date, no study has yet examined the developmental trajectory of comorbid psychiatric symptoms across the lifespan within the AD population. Therefore, the purpose of this study was to conduct a cross-sectional investigation of symptoms of anxiety across the lifespan, using a sample of individuals diagnosed with AD. This study utilizes a sample with an age range from infancy to adulthood. Endorsement rates of overlapping anxiety symptoms from measures that have been found reliable and valid for the specific purpose of examining psychiatric symptoms within the AD population are utilized for this study. Results indicate that there is a significant difference between different age cohorts on symptom endorsements of anxiety. Additionally, a cubic trend was found when examining the pattern of anxiety symptoms across the lifespan in those diagnosed with AD. That is, anxiety rises from toddlerhood to childhood, decreases from childhood to young adulthood, but again increases from young adulthood into older adulthood. Implications of these findings, limitations of this study, and future directions for research are discussed.

Comorbid psychopathology factor structure on the Baby and Infant Screen for Children with aUtIsm Traits-Part 2 (BISCUIT-Part 2) / Johnny L. MATSON in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)

However, many of these studies focus on children or adults, with research on infants and toddlers evincing ASD being virtually non-existent. Even more scant is information pertaining to the assessment of symptoms of comorbid psychopathology in this young population. Nonetheless, it is essential to identify comorbid conditions in addition to the symptoms associated with the core features of ASD. Building on the effectiveness of early intervention with children with ASD, comprehensive evaluations and individualized treatment goals are necessary and may enhance treatment efficacy. The Baby and Infant Screen for Children with aUtIsm Traits-Part 2 (BISCUIT-Part 2) is a new assessment, specifically designed to examine symptoms of psychopathology in infants and toddlers with ASD. The purpose of this study was twofold. First, the factor structure of the BISCUIT-Part 2 was established. Second, group differences in the endorsement of symptoms of psychopathology were examined between infants and toddlers with and without ASD.

Research is scant on symptoms of co-occurring mental health conditions in this very young population. Method: Three hundred and twenty four participants were included in this study. Participants were classified into one of three groups: Autistic Disorder, Pervasive Developmental Disorder-Not Otherwise Specified, and control. A Multivariate Analysis of Variance (MANOVA) was utilized to assess group differences on the six subscales of the Baby and Infant Screen for Children with aUtIsm Traits-Part 2 (BISCUIT-Part 2). Results: The MANOVA revealed a significant main effect for group. Follow-up analyses showed that all subscales contributed to the significant main effect of the MANOVA. Discussion: The results of the analyses in this study are consistent with the current literature on older children and adults with ASDs. Implications of early identification of comorbid disorders are discussed. Further research on the mental health of infants and toddler with autism spectrum disorders (ASDs) is warranted.

The methodology consisted of testing the similarity of findings between the ASD-DC and the Autism Diagnostic Interview-Revised (ADI-R), which proved to be statistically significant for subscale content scores on social, communication, and rituals/insistence on sameness/restrictive interest subfactors. Secondly, the ASD-DC and ADI-R were compared to clinically derived diagnoses based on diagnostic interviews, rating scales, a DSM-IV/ICD-10 symptom checklist, observations of the child, clinical judgment, and an in-depth parent interview. Twenty-six children in the study met criteria for ASD while six did not. The ASD-DC correctly identified 73% of the ASD group and 67% of the controls, while the ADI-R correctly identified 46% of the ASD group and 100% of the controls. The implications of these data are discussed.
