Autism spectrum disorders in adults with intellectual disability and comorbid psychopathology: Scale development and reliability of the ASD-CA / Johnny L. MATSON in Research in Autism Spectrum Disorders, 2-2 (April-June 2008)

BOISJOLI, Auteur Année de publication : 2008 Article en page(s) : p.276-287 Langues : Anglais (eng) Mots-clés : Assessment Autism Comorbidity Intellectual-disability Index. décimale : PER Périodiques Résumé : Researchers and clinicians have generally agreed that persons with autism spectrum disorders (ASD) are susceptible to other DSM Axis I disorders. However, to date, little has been done to establish the specific disorders, their rate and severity of occurrence, and their interrelationship with ASD symptoms. One reason for the lack of research has been the absence of a comorbidity measure for this population. Additionally, when research has been conducted, it typically has been on one disorder with young children. The present study assessed comorbid DSM Axis I disorders in adults with ASD, either autism or PDDNOS and intellectual disabilities, using a new scale designed for the purpose. The reliability and factor structure of the scale was evaluated and implications for future 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)

BOISJOLI, Auteur ; Julie HESS, Auteur Année de publication : 2011 Article en page(s) : p.426-432 Langues : Anglais (eng) Mots-clés : BISCUIT Autism Infant-screening Psychopathology Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorders (ASD) is a topic receiving great attention from researchers and clinicians in the field. 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.

Comorbid psychopathology in infants and toddlers with autism and pervasive developmental disorders-not otherwise specified (PDD-NOS) / Johnny L. MATSON in Research in Autism Spectrum Disorders, 4-2 (April-June 2010)

BOISJOLI, Auteur ; Julie HESS, Auteur Année de publication : 2010 Article en page(s) : p.300-304 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The purpose of this study was to investigate symptoms of comorbid disorders in infants and toddlers with autism spectrum disorders (ASDs). 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.

Differential diagnosis of PDDNOS in children / Johnny L. MATSON in Research in Autism Spectrum Disorders, 1-1 (January/March 2007)

Having said that, it is often diagnosed by what it is not (not autism) as opposed to what it is. And, while PDDNOS is likely to be more common than autism, studies on PDDNOS are much less frequent. Perhaps with the exception of childhood degenerative disorder, PDDNOS has less diagnostic research on it than any other ASD. The purpose of the present paper was to review the available research on the definition and diagnosis of PDDNOS. The data are analyzed and future goals for conceptual and diagnostic research are discussed with the idea of further enhancing a neglected diagnostic category.

A factor analysis of challenging behaviors assessed with the Baby and Infant Screen for Children with aUtism Traits (BISCUIT-Part 3) / Johnny L. MATSON in Research in Autism Spectrum Disorders, 3-3 (July-September 2009)

In addition to these core deficits, individuals with ASD also experience co-occurring conditions such as problem behaviors. Problem behaviors are common to this population and can have detrimental effects on the person's life and those who care for them. Due to the consequences of these behaviors, regular monitoring is necessary to identify these behaviors and implement treatment. The BISCUIT-Part 3 is the only measure designed to assess problem behaviors in infants and toddlers with ASD. The purpose of this study was to identify the factor structure of the BISCUIT-Part 3 through exploratory factor analysis and determine the ability of these factors to predict group membership.
