Repetitive Behaviour and Play in Typically Developing Children and Children with Autism Spectrum Disorders / Emma HONEY in Journal of Autism and Developmental Disorders, 37-6 (July 2007)
[article]
Titre : Repetitive Behaviour and Play in Typically Developing Children and Children with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Emma HONEY, Auteur ; Michelle TURNER, Auteur ; Susan R. LEEKAM, Auteur ; Helen MCCONACHIE, Auteur Année de publication : 2007 Article en page(s) : p.1107-1115 Langues : Anglais (eng) Mots-clés : Autism Repetitive-behaviours Play Parental report Questionnaire Index. décimale : PER Périodiques Résumé : The view of a triad of impairments [(Wing and Gould (1979). Journal of Autism and Developmental Disorders, 9, 11–30] in which impaired imagination is linked with repetitive behaviour is widely accepted. However this categorisation differs from the international classification systems, which link imagination to communication impairments rather than to repetitive behaviours. To investigate this relationship, the Activities and Play Questionnaire-Revised was completed by 196 parents of 2–8-year-old children with autism spectrum disorders (ASD) and typical development. Results showed that repetitive behaviours were associated with play in ASD but not in typical development, supporting Wing and Gould’s triad. However there was also an association between play, repetitive behaviour and language, confirming the international classification systems description of imagination as a component of language and communication difficulties.

The current study investigated the frequency and factor structure of repetitive behaviours in a large community sample of 2-year-olds.
Methods: A new measure, the Repetitive Behaviour Questionnaire (RBQ-2) was completed by 679 parents.
Results: The RBQ-2 had good psychometric properties. A four-factor model provided the best fit for the data, accounting for 51% of the variance, and suggested 4 sub-scales: unusual sensory interests, repetitive motor movements, rigidity/adherence to routine and preoccupations with restricted patterns of interest. These sub-scales closely resembled repetitive behaviour subtypes within the ICD-10 criteria for autism. Repetitive behaviours of every type were frequently reported. Higher scores were found for all children, and especially boys, on the subscale relating to preoccupations with restricted patterns of interests.
Conclusion: The results support the proposal that repetitive behaviours represent a continuum of functioning that extends to the typically developing child population.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2007.01778.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=298

Titre : Social Interest in High-Functioning Adults With Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Sue FLETCHER-WATSON, Auteur ; Susan R. LEEKAM, Auteur ; John M. FINDLAY, Auteur Année de publication : 2013 Article en page(s) : p.222-229 Langues : Anglais (eng) Mots-clés : high-functioning autism Asperger syndrome content analysis social interest Index. décimale : PER Périodiques Résumé : Autism spectrum disorders (ASD) are principally characterized by impairments in social functioning. Experimental investigation often is conducted using methods measuring social attention, social cognition, and social communication. In this study, we instead measured interest in social information, making a distinction between basic-level person-centered social information such as physical attributes of people (“human” information) and high-level social information such as hypotheses about mental states, emotion, and relationships (“social” information). Based on content analysis of verbal descriptions of color images, 31 young adults (4 women), aged 17 to 25 years with ASD, and 35 typically developing young adults (8 women), aged 17 to 31 years, devoted similar proportions of their descriptions to human and social topics. Results are interpreted in the context of current calls for more ecologically valid methodology and in relation to other assessments of social processing in ASD.

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.

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 : Targets and Cues: Gaze-following in Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Susan R. LEEKAM, Auteur ; Emma HUNNISETT, Auteur ; Chris MOORE, Auteur Année de publication : 1998 Article en page(s) : p.951-962 Langues : Anglais (eng) Mots-clés : Autism attention nonverbal communication gaze-following joint attention Index. décimale : PER Périodiques Résumé : Children with autism are known to have difficulties in sharing attention with others. Yet one joint attention behaviour, the ability to follow another person's head turn and gaze direction, may be achieved without necessarily sharing attention. Why, then, should autistic children have difficulties with it? In this study we examined the extent of this difficulty by testing school-aged autistic children across three different contexts; experiment, observation, and parent interview. We also tested whether the ability to orient to another person's head and gaze could be facilitated by increasing children's attention to environmental targets and social cues. Results for experiment and observation demonstrate that a sizeable proportion of children with autism did not have difficulties with following another's head turn. There was a difference between children with high and low verbal mental ages, however. Whereas children with higher mental ages (over 48 months) were able to orient spontaneously to another person's head turn, children with lower mental ages had difficulties with this response. When cues were added (pointing, language) or when feedback from targets was given, however, their performance improved. Parent interview data indicated that children with autism, whatever their mental age, began to follow head turn and gaze direction years later than typically developing children. Developments in attention and language are proposed as possible factors to account for this developmental delay.
