Age and sex differences in problem behaviours in youth with autism spectrum disorder / Gemma GRAZIOSI in Research in Autism Spectrum Disorders, 100 (February 2023)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 100 (February 2023) . - 102075 Titre : Age and sex differences in problem behaviours in youth with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Gemma GRAZIOSI, Auteur ; Adrienne PERRY, Auteur Article en page(s) : 102075 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Problem Behaviour  Age  Sex  Developmental level Index. décimale : PER Périodiques Résumé : Background Many youth with autism spectrum disorder (ASD) display problem behaviours. Although previous studies have examined age and sex differences in problem behaviours in youth with ASD, most have done so with samples that exhibited a limited range of adaptive or intellectual functioning. This study sought to examine age and sex differences in problem behaviours in youth with ASD who were diverse in age and developmental level. Method Levels of problem behaviour, as measured by the Aberrant Behavior Checklist, were examined according to age, sex, and developmental level using data from 457 inpatients (4 “20 years old; 94 females) enrolled in the SFARI Autism Inpatient Collection. Multiple regression analyses were conducted to determine the extent to which participant characteristics predict problem behaviours. Results Age was somewhat negatively correlated with irritability and total problem behaviours and moderately negatively correlated with hyperactivity. Females exhibited significantly greater scores for irritability than males. Developmental level was negatively correlated with most problem behaviours. Age, sex, and developmental level in combination accounted for a small amount of variance in most problem behaviours. Conclusions Specific problem behaviours in youth with ASD showed some age- and sex-related differences. Higher levels of problem behaviours were also associated with lower developmental level. The generalizability of these findings may be limited due to the sample consisting exclusively of inpatients. Nonetheless, recognizing differences in levels and types of problem behaviour among youth with ASD can be useful for the development and implementation of effective intervention strategies, especially in those with lower adaptive or intellectual functioning.

Associations of age, anxiety, cognitive functioning, and social impairment with aggression in youth with autism / Ethan RINALDO in Research in Autism Spectrum Disorders, 108 (October 2023)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 108 (October 2023) . - p.102246 Titre : Associations of age, anxiety, cognitive functioning, and social impairment with aggression in youth with autism Type de document : Texte imprimé et/ou numérique Auteurs : Ethan RINALDO, Auteur ; Adrienne PERRY, Auteur Article en page(s) : p.102246 Mots-clés : Autism  Aggression  Anxiety  Social impairment  Cognitive functioning Index. décimale : PER Périodiques Résumé : Background Previous research has indicated that aggression in children with autism is associated with cognitive functioning, age, anxiety, and social functioning, although most samples only include parent-report measures and participants without intellectual disability. Furthermore, there is a lack of research investigating how different aspects of social impairment are associated with aggressive behaviour in youth with autism while anxiety is included in the analyses. The aim of this study was to clarify the relationships of these variables with aggression in a large sample, diverse in age and cognitive level, using both parent- and teacher-report measures. Method Participants were 1179 youth (age 4-18) with a diagnosis of autism spectrum disorder, from the SFARI database. Parent- and teacher-report measures were obtained for aggression, anxiety, and social impairment. Univariate statistics were calculated to determine how each variable was associated with aggression and hierarchical regressions were conducted with all variables together. Results Age and intellectual disability presence/severity had small positive relationships with teacher-measured aggression while anxiety and social impairment severity had strong relationships with aggression when rated by both parents and teachers. In a regression analysis, anxiety and social communication problems had the strongest positive relationships with aggression while social motivation problems had a negative relationship with aggression. Conclusion These results indicate the importance of anxiety and social problems, particularly in social communication and motivation, when studying and treating aggression in youth with autism.

Brief Report: The Vineland Adaptive Behavior Scales in Young Children with Autism Spectrum Disorders at Different Cognitive Levels / Adrienne PERRY in Journal of Autism and Developmental Disorders, 39-7 (July 2009)

IQ was higher than VABS composite score among high functioning children only; the opposite pattern was found in lower IQ subgroups. Profile analysis of VABS domains across cognitive levels demonstrated different profiles in different subgroups. A characteristic “autism profile” was found for most subgroups for Age Equivalents but not Standard Scores. In a small set of matched pairs (n = 28) of children with autism versus MR, significantly different profiles were found, with Socialization and Communication lower in autism, but no differences were found between matched pairs of children with autism and PDD-NOS (n = 48). Correlations between age, cognitive level, and adaptive level were also reported, and regression analyses indicated that autism severity accounts for a modest amount of unique variance in Socialization and Daily Living Skills.

Effectiveness of Intensive Behavioral Intervention in a large, community-based program / Adrienne PERRY in Research in Autism Spectrum Disorders, 2-4 (October 2008)

This study reports on the outcomes of 332 children, aged 2–7 years, enrolled in a large, community-based, publicly funded IBI Program in Ontario, Canada. File review data at intake and exit were compared on a group basis as well as on an individual basis. Results indicated statistically significant and clinically significant improvements: reduction in autism severity, gains in cognitive and adaptive levels, as well as a doubling of children's rate of development. There was a considerable heterogeneity in outcome, as expected, and children were classified into seven categories of progress/outcome. The majority of children (75%) showed some gains during IBI and 11% achieved average functioning. Although the study has clear methodological limitations (chiefly the lack of a comparison group), it suggests that IBI can be implemented effectively in a large, community-based program.

Effectiveness of large-scale community-based Intensive Behavioral Intervention: A waitlist comparison study exploring outcomes and predictors / Helen E. FLANAGAN in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)

Outcomes were compared for 61 children who received IBI and 61 individually matched children from a waitlist comparison group. In addition, predictors of better cognitive outcomes were explored (n = 142). Although random assignment did not take place, a standardized waitlist management system was used that did not include any prioritization other than time of referral. Groups did not differ significantly on available measures at intake. The treatment period tended to be longer than the waitlist period and this difference was controlled in analyses. At exit, the IBI group had better outcomes in all measured areas, with milder autism severity, higher adaptive functioning, and higher cognitive skills. Younger initial age predicted better cognitive outcomes in the IBI group but not the Waitlist group. Higher initial adaptive skills predicted better outcomes similarly in the two groups. Results support the effectiveness of community-based IBI and suggest that earlier age at treatment onset may increase the likelihood of better outcomes relative to comparison conditions.
