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)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 2-4 (October 2008) . - p.621-642 Titre : Effectiveness of Intensive Behavioral Intervention in a large, community-based program Type de document : Texte imprimé et/ou numérique Auteurs : Adrienne PERRY, Auteur ; Anne CUMMINGS, Auteur ; Jennifer DUNN GEIER, Auteur ; Nancy L. FREEMAN, Auteur ; Susan HUGHES, Auteur ; Louise LAROSE, Auteur ; Tom MANAGHAN, Auteur ; Jo-Ann REITZEL, Auteur ; Janis WILLIAMS, Auteur Année de publication : 2008 Article en page(s) : p.621-642 Langues : Anglais (eng) Mots-clés : Behavioral-treatment Early-Intensive-Behavioral-Intervention-Effectiveness-study Outcomes Index. décimale : PER Périodiques Résumé : Although the efficacy of Intensive Behavioral Intervention (IBI) for young children with Autism Spectrum Disorders (ASD) has been well documented in small model programs, IBI's effectiveness (i.e., does it work in the “real world”?) has been less studied and may not be as impressive, e.g. Bibby, Eikeseth, Martin, Mudford, and Reeves (2002). 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.

Predictors of outcome for children receiving intensive behavioral intervention in a large, community-based program / Adrienne PERRY in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)

Data documenting children's progress were reported in an earlier publication (Perry et al., 2008). The present paper explores the degree to which four predictors (measured at intake to IBI) are related to children's outcomes: age at entry, IQ, adaptive scores, and autism severity. Outcome variables examined include: post-treatment scores for: autism severity, adaptive behavior, cognitive level, rate of development in IBI, and categorical progress/outcomes (seven subgroups). All four types of predictors were related to children's outcomes, although initial cognitive level was the strongest predictor. In addition, two subgroups of the sample are examined further. Children who were most successful in the program and achieved average functioning had higher developmental levels at intake, were considerably younger than the rest of the children, and were in treatment longer than children in other outcome categories. Children who were least successful in the program and made essentially no progress did not differ appreciably from the remainder of the group. Implications of these results for decision-making are discussed.

The relative importance of age and IQ as predictors of outcomes in Intensive Behavioral Intervention / Adrienne PERRY in Research in Autism Spectrum Disorders, 7-9 (September 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-9 (September 2013) . - p.1142-1150 Titre : The relative importance of age and IQ as predictors of outcomes in Intensive Behavioral Intervention Type de document : Texte imprimé et/ou numérique Auteurs : Adrienne PERRY, Auteur ; Ksusha BLACKLOCK, Auteur ; Jennifer DUNN GEIER, Auteur Article en page(s) : p.1142-1150 Langues : Anglais (eng) Mots-clés : Intensive Behavioral Intervention  Predictors of outcome  Cognitive  IQ  Adaptive behavior  Age effects Index. décimale : PER Périodiques Résumé : Abstract Outcomes of Intensive Behavioral Intervention are known to be highly variable. We report on two studies examining the role of age at entry to treatment and initial IQ in relationship to cognitive and adaptive outcomes in the Ontario province-wide program. Study 1 included 207 children aged 2–14 at entry. Age was modestly negatively correlated with several outcome variables; IQ was strongly predictive of most cognitive and adaptive outcomes. Age accounted for additional variance, beyond that accounted for by IQ, for cognitive outcomes, especially change in IQ. Children who made very large gains were all under age 6 at entry. Children who were over 8 years of age and/or had very low IQ showed uniformly poor outcomes. Study 2 was a comparison of IQ-matched younger (2–5 years) versus older (6–13 years) children (n = 60 each). The two groups of children, who were on the same initial trajectory, showed different outcomes. Only the younger group showed substantial cognitive gains. Results strongly argue for the importance of early intervention.
