Changes to the DSM-5 Autism Spectrum Disorder (ASD) criteria raised concerns among parents and practitioners that the criteria may exclude some children with Pervasive Developmental Disorder (PDD). Few studies have examined DSM-5 sensitivity and specificity in children less than 5 years of age. This study evaluated 185 children aged 20-55 months with DSM-IV PDD or developmental delay. Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule (ADOS) data was assigned to DSM-5 subdomains. Children displaying the required symptomatology were classified with DSM-5 ASD. DSM-IV clinical diagnoses were compared to DSM-5 classifications. Using combined ADI-R/ADOS information, sensitivity was .84 and specificity was .54. Comorbid behaviour and emotional problems were significantly lower in children with PDD that did not meet DSM-5 criteria., Author(s): Jessica A. Christiansz[sup.1] , Kylie M.

Longitudinal research has demonstrated that social outcomes for adults with autism are restricted, particularly in terms of employment and living arrangements. However, understanding of individual and environmental factors that influence these outcomes is far from complete. This longitudinal study followed a community sample of children and adolescents with autism into adulthood. Social outcomes in relation to community inclusion and living skills were examined, including the predictive role of a range of individual factors and the environment (socioeconomic disadvantage). Overall, the degree of community inclusion and living skills was restricted for the majority, and while childhood IQ was an important determinant of these outcomes, it was not the sole predictor. The implications of these findings in relation to interventions are discussed. Keywords Autism * Community inclusion * Living skills Adult outcomes, Introduction Studies of adult outcomes in autism have focused on broad constructs of outcome, typically including evaluations of social functioning in terms of independence, social relationships, employment status, and living [...]

The current study aims to evaluate the psychometric properties of the Emotion Regulation and Social Skills Questionnaire (ERSSQ), a rating scale designed specifically to assess the social skills of young people with Autism Spectrum Disorder (ASD). The participants were 84 children and young adolescents with ASD, aged between 7.97 and 14.16 years with a mean IQ score of 90.21 (SD = 18.82). The results provide evidence for the concurrent and criterion validity of the ERSSQ Parent form, and the concurrent validity of the ERSSQ Teacher form. The clinical and theoretical implications are discussed, including the necessity of ratings across multiple contexts and the potential use of the ERSSQ in identifying individuals most in need of intervention and for planning and assessing the outcomes of social skills interventions. Keywords ERSSQ * Social skills * Autism Spectrum Disorders ASD Validation, Introduction Autism Spectrum Disorders (ASD) are pervasive and lifelong developmental disorders that are characterized by marked impairments in social interaction, communication, and patterns of restricted/repetitive behaviors or interests (American Psychiatric [...]

This study investigated the relationship between structural language skills, and communication skills, adaptive behavior, and emotional and behavior problems in pre-school children with autism. Participants were aged 3-5 years with autism (n = 27), and two comparison groups of children with developmental delay without autism (n = 12) and typically developing children (n = 20). The participants were administered standardised tests of structural language skills, and parents completed the Vineland Adaptive Behavior Scales and the Developmental Behaviour Checklist. Results indicated that for children with autism, communication skills, and in particular receptive communication skills, were associated with social and daily living skills, and behavior problems. Receptive structural language skills were associated with expressive communication skills. There were no associations found between structural language skills and social or daily living skills, nor behavior problems. The results of this study suggest that communication skills are more closely linked to functional and behavioral outcomes in autism than structural language skills. Keywords Autism * Language * Adaptive behavior * Behavior problems, Introduction In addition to social impairments and restricted and repetitive behaviors, many children with autism also experience language deficits (Park et al. 2012), behavior problems (Baghdadli et al. 2003; Herring [...]

This paper examines the upper-limb movement kinematics of young children (3-7 years) with high-functioning autism using a point-to-point movement paradigm. Consistent with prior findings in older children, a difference in movement preparation was found in the autism group (n = 11) relative to typically developing children. In contrast to typically developing children, the presence of a visual distractor in the movement task did not appear to impact on early movement planning or execution in children with autism, suggesting that this group were not considering all available environmental cues to modulate movement. The findings from this study are consistent with the possibility that autism is associated with a difficulty using visual information to prime alternative movements in a responsive way to environmental demands. Keywords Autism * Motor processes * Movement kinematics * Motor preparation * Visual integration, Introduction Existing estimates suggest that at least 63% of children with an Autism Spectrum Disorder (ASD) aged 2-6 years present with a neurological motor impairment (Ming et al. 2007), with [...]

The aim of the current study was to investigate the manifestation of repetitive behaviour profiles in young children with a Pervasive Developmental Disorder. The sample consisted of 137 developmentally delayed children with a DSM-IV-TR Pervasive Developmental Disorder (PDD) and 61 developmentally delayed children without a PDD. An exploratory factor analytic investigation using 12 ADI-R repetitive behaviour items from parent report of children with a PDD reported the emergence of two factors. The first factor consisted of higher-level, "insistence on sameness" behaviours, and the second of lower-level, repetitive "sensory-motor" behaviours. This factor structure was also applicable to a more general group of young children with developmental delay, regardless of their diagnosis. Correlational analyses highlighted contrasting relationships between developmental variables and the different repetitive behaviour factors. These relationships were different for children with a PDD and those without a PDD. The findings have potential implications for the early assessment and diagnosis of PDDs in young children.
