Titre : Subdomains of restricted and repetitive behaviors within autism: Exploratory structural equation modeling using the diagnostic interview for social and communication disorders Type de document : Texte imprimé et/ou numérique Auteurs : Mirko ULJAREVIC, Auteur ; Sarah J. CARRINGTON, Auteur ; Antonio Y. HARDAN, Auteur ; Susan R. LEEKAM, Auteur Article en page(s) : p.861-869 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/diagnosis Autistic Disorder/diagnosis Child Communication Disorders/diagnosis Female Humans Intellectual Disability Latent Class Analysis Male Stereotyped Behavior circumscribed interests diagnostic interview for social and communication disorders factor analysis insistence on sameness repetitive behaviors sensory sensitivity Index. décimale : PER Périodiques Résumé : The current study aimed to explore the factor structure of a broad range of restricted and repetitive behaviors (RRB) within the autism spectrum. Exploratory structural equation modeling was conducted using individual item-level data from the Diagnostic Interview for Social and Communication Disorders (DISCO). DISCO is a comprehensive semi-structured interview used by clinicians to elicit information from caregivers about the individual's profile of development and behavior. Data from a sample of 226 individuals with a clinical diagnosis of autism spectrum disorder (ASD) (189 males; M(age) = 11.82?years, SD(age) = 7.87) were analyzed. The six-factor structure provided the most optimal and interpretable fit (comparative fit index = 0.944, Tucker-Lewis index = 0.923, root mean square error of approximation = 0.018). Derived factors were interpreted as repetitive motor behaviors (RMB), unusual sensory and object focused interests (USOI), sensory sensitivity (SS), insistence on sameness (IS), circumscribed interests (CI) and stereotyped language (SL). Age was significantly negatively associated with RMB, USOI and SL but not with SS, IS or CI factor scores. None of the factors were associated with sex. ASD individuals with intellectual disability (ID) had the highest RMB, USOI, SS and SL scores while those without ID had the highest IS and CI scores. Our findings provide preliminary evidence for the utility of the DISCO as a comprehensive measure of several distinct RRB domains in both research and clinical contexts. Importantly, the current investigation highlights crucial areas for measurement development. LAY SUMMARY: The diagnostic Interview for Social and Communication Disorders (DISCO) is a detailed caregiver report clinical interview designed to capture a wide range of key features associated with autism spectrum disorder, including restricted and repetitive behaviors (RRB). This paper provides initial evidence that the DISCO is a promising measure for assessing a wide range of RRB including repetitive motor behaviors, insistence on sameness, circumscribed interests, unusual interests in sensory stimuli, sensory sensitivity and stereotypic language.

Titre : Subgroups of Temperament Associated with Social-Emotional Difficulties in Infants with Early Signs of Autism Type de document : Texte imprimé et/ou numérique Auteurs : Lacey CHETCUTI, Auteur ; Mirko ULJAREVIC, Auteur ; Kandice J. VARCIN, Auteur ; Maryam BOUTRUS, Auteur ; Ming Wai WAN, Auteur ; Jonathan GREEN, Auteur ; Teresa IACONO, Auteur ; Cheryl DISSANAYAKE, Auteur ; Andrew J. O. WHITEHOUSE, Auteur ; Kristelle HUDRY, Auteur Article en page(s) : p.2094-2101 Langues : Anglais (eng) Mots-clés : autism spectrum disorder externalizing infants internalizing temperament Index. décimale : PER Périodiques Résumé : Links between temperament and social-emotional difficulties are well-established in normative child development but remain poorly characterized in autism. We sought to characterize distinct temperament subgroups and their associations with concurrent internalizing and externalizing symptoms in a sample of 103 infants (M(age) = 12.39?months, SD = 1.97; 68% male) showing early signs of autism. Latent profile analysis was used to identify subgroups of infants with distinct temperament trait configurations on the Infant Behavior Questionnaire-Revised. Derived subgroups were then compared in terms of internalizing and externalizing symptoms on the Infant-Toddler Social and Emotional Assessment. Three distinct temperament subgroups were identified: (a) inhibited/low positive (n = 22), characterized by low Smiling and Laughter, low High-Intensity Pleasure, low Vocal Reactivity, and low Approach; (b) active/negative reactive (n = 23), characterized by high Activity Level, high Distress to Limitations, high Sadness, high Fear, and low Falling Reactivity; and (c) well-regulated (n = 51), characterized by high Cuddliness, high Soothability, and high Low-Intensity Pleasure. There were no differences in infant sex ratio, mean age or developmental/cognitive ability. Inhibited/low-positive infants had significantly more behavioral autism signs than active/negative reactive and well-regulated infants, who did not differ. Inhibited/low-positive and active/negative reactive infants had higher internalizing symptoms, relative to well-regulated infants, and active/negative reactive infants also had higher externalizing symptoms. These findings align closely with those garnered in the context of normative child development, and point to child temperament as a putative target for internalizing and externalizing interventions. LAY SUMMARY: This study explored whether infants with early signs of autism could be grouped according to temperament characteristics (i.e., emotional, behavioral, and attentional traits). Three subgroups were identified that differed with respect to emotional and behavioral difficulties. Specifically, "inhibited/low-positive" infants had high emotional difficulties, "active/negative reactive" infants had high emotional and behavioral difficulties, while "well-regulated" infants had the lowest difficulties.

In Study 1, The Repetitive Behaviours Questionnaire-2 for adults (RBQ-2A) was completed by a sample of 163 neurotypical adults. Principal components analysis revealed two components: Repetitive Motor Behaviours and Insistence on Sameness. In Study 2, the mean RBQ-2A scores of a group of adults with autism spectrum disorder (ASD; N = 29) were compared to an adult neurotypical group (N = 37). The ASD sample had significantly higher total and subscale scores. These results indicate that the RBQ-2A has utility as a self-report questionnaire measure of RRBs suitable for adults, with potential clinical application.

The aim of this study was to explore the psychometric properties of the Hospital Anxiety and Depression Scale [HADS; Zigmond & Snaith, ] in a sample of older adolescents and young adults with ASD. One hundred and fifty one participants (UK Transition longitudinal study: N?=?106; 75 males, Mage?=?16.04 years, SD?=?1.28; Longitudinal Study of Australian Schools Leavers with ASD: N?=?45, 30 males; Mage?=?18.35 years, SD?=?2.55) completed the HADS and a range of mental health and well?being measures. Combination of the Principal Component Analysis and Parallel Analysis indicated two factors as an optimal solution in our sample, accounting for 43.77% of variance with factors being identical in terms of content with the structure found in the general population. Internal consistency was good for the HADS anxiety scale (HADS?A; .82–.84) and acceptable for the HADS depression scale (HADS?D; .60–.72). Convergent validity of both HADS?A and HADS?D scales was excellent and divergent validity was acceptable.

Despite an increasing number of studies, there is no clear agreement on which existing anxiety measure is more psychometrically sound and what is the factor structure of anxiety in ASD. The present study examined the internal consistency, convergent, divergent, and discriminant validity, as well as the factor structure of the Spence Children's Anxiety Scale-Parent Version (SCAS-P), in a large international pooled sample of 870 caregivers of youth with ASD from 12 studies in the United Kingdom, United States, and Singapore who completed the SCAS-P. Most were community recruited, while the majority had at least one measure of ASD symptomatology and either cognitive or adaptive functioning measures completed. Existing SCAS-P total scale and subscales had excellent internal consistency and good convergent, divergent and discriminant validity similar to or better than SCAS-P properties reported in typically developing children, except for the poorer internal consistency of the physical injury subscale. Confirmatory Factor Analysis (CFA) of the existing SCAS-P six-correlated factor structure was a poor fit for this pooled database. Principal component analysis using half of the pooled sample identified a 30-item five correlated factor structure, but a CFA of this PCA-derived structure in the second half of this pooled sample revealed a poor fit, although the PCA-derived SCAS-P scale and subscales had stronger validity and better internal consistency than the original SCAS-P. The study's limitations, the use of the SCAS-P to screen for DSM-derived anxiety problems in ASD and future research directions are discussed.
