Indices of diagnostic accuracy have been shown to be strong in school-aged samples; however, relatively little is known about the performance of the SCQ in toddlers at risk of autism spectrum disorder (ASD). Methods:  This study replicates and extends previous research by Corsello et al. (2007) in a comparatively large (N = 208), substantially younger (20–40 months) sample of children at high risk of ASD. The usefulness of the SCQ as a second-level screening instrument with different cut-off scores was evaluated in relation to IQ, age, and type of ASD diagnosis. The use of the SCQ as compared to the ADI-R was evaluated against clinical diagnosis, both alone and in combination with the ADOS. Results:  The SCQ with different cut-offs consistently showed an unsatisfactory balance between sensitivity and specificity in screening for ASD in high-risk toddlers, with only a few exceptions for specific age, IQ, or diagnostic groups. Even though the SCQ and ADI-R were highly correlated, diagnostic agreement with the best evidence clinical diagnosis was poor for both measures. The ADOS used alone consistently had the highest predictive value. For autism versus not-autism, the combined SCQ and ADOS performed as well as the ADOS alone and notably better than the combination ADI-R and ADOS. Conclusions:  The SCQ is likely to result in a number of false-positive findings, particularly in children with autism symptomatology, and the balance between sensitivity and specificity is poor. The ADOS should be considered the most valid and reliable diagnostic instrument in these very young at-risk children.

Improved Diagnostic Validity of the ADOS Revised Algorithms: A Replication Study in an Independent Sample / Iris J. OOSTERLING in Journal of Autism and Developmental Disorders, 40-6 (June 2010)

(2007) proposed revised algorithms for the Autism Diagnostic Observation Schedule (ADOS) with improved diagnostic validity. The aim of the current study was to replicate predictive validity, factor structure, and correlations with age and verbal and nonverbal IQ of the ADOS revised algorithms for Modules 1 and 2 in a large independent Dutch sample (N = 532). Results showed that the improvement of diagnostic validity was most apparent for autism, except in very young or low functioning children. Results for other autism spectrum disorders were less consistent. Overall, these findings support the use of the more homogeneous revised algorithms, with the use of similar items across developmental cells making it easier to compare ADOS scores within and between individuals.

Randomized Controlled Trial of the Focus Parent Training for Toddlers with Autism: 1-Year Outcome / Iris J. OOSTERLING in Journal of Autism and Developmental Disorders, 40-12 (December 2010)

The training focused on stimulating joint attention and language skills and was based on the intervention described by Drew et al. (Eur Child Adolesc Psychiatr 11:266–272, 2002). Seventy-five toddlers with autism spectrum disorder (65 autism, 10 PDD-NOS, mean age = 34.4 months, SD = 6.2) were enrolled. Analyses were conducted on a final sample of 67 children (lost to follow-up = 8). No significant intervention effects were found for any of the primary (language), secondary (global clinical improvement), or mediating (child engagement, early precursors of social communication, or parental skills) outcome variables, suggesting that the ‘Focus parent training’ was not of additional value to the more general care-as-usual.
