Cost, Katherine T.; Zaidman-Zait, Anat; Mirenda, Pat; Duku, Eric; Zwaigenbaum, Lonnie; Smith, Isabel M.; Ungar, Wendy J.; Kerns, Connor; Bennett, Theresa; Szatmari, Peter; Georgiades, Stelios; Waddell, Charlotte; Elsabbagh, Mayada; Vaillancourt, Tracy – Journal of Autism and Developmental Disorders, 2021
This study examined parental perceptions of the character traits of children with autism from early childhood to age 11. Parents (n = 153) provided descriptions of the "best things" about their children on the Child Behavior Checklist (CBCL) at ages 3-4, 7-8, and 10-11 years. Descriptions were coded using the framework of the Values in…

The latent class structure of autism symptoms from the time of diagnosis to age 6 years was examined in a sample of 280 children with autism spectrum disorder. Factor mixture modeling was performed on 26 algorithm items from the Autism Diagnostic Interview-Revised at diagnosis (Time 1) and again at age 6 (Time 2). At Time 1, a…

Bennett, Teresa A.; Szatmari, Peter; Georgiades, Katholiki; Hanna, Steven; Janus, Magdelena; Georgiades, Stelios; Duku, Eric; Bryson, Susan; Fombonne, Eric; Smith, Isabel M.; Mirenda, Pat; Volden, Joanne; Waddell, Charlotte; Roberts, Wendy; Vaillancourt, Tracy; Zwaigenbaum, Lonnie; Elsabbagh, Mayada; Thompson, Ann – Journal of Child Psychology and Psychiatry, 2015
Background: Differences in how developmental pathways interact dynamically in children with autism spectrum disorder (ASD) likely contribute in important ways to phenotypic heterogeneity. This study aimed to model longitudinal reciprocal associations between social competence (SOC) and language (LANG) pathways in young children with ASD. Methods:…

Path analysis within a structural equation modeling framework was employed to examine the relationships between two types of parent stress and children's externalizing and internalizing behaviors over a 4-year period, in a sample of 184 mothers of young children with autism spectrum disorder. Parent stress was measured with the Parenting Stress…

Kaori; Mirenda, Pat; Marinova-Todd, Stefka; Hambly, Catherine; Fombonne, Eric; Szatmari, Peter; Bryson, Susan; Roberts, Wendy; Smith, Isabel; Vaillancourt, Tracy; Volden, Joanne; Waddell, Charlotte; Zwaigenbaum, Lonnie; Georgiades, Stelios; Duku, Eric; Thompson, Ann – Research in Autism Spectrum Disorders, 2012
The purpose of this study was to compare a group of recently diagnosed bilingual-exposed children with autism (n = 20) aged 24-2 months with a matched group of monolingual-exposed children with autism (n = 40). The groups were matched with regard to chronological age at the time of language assessment and nonverbal IQ score, then compared with…

Bennett, Teresa; Boyle, Michael; Georgiades, Katholiki; Georgiades, Stelios; Thompson, Ann; Duku, Eric; Bryson, Susan; Fombonne, Eric; Vaillancourt, Tracy; Zwaigenbaum, Lonnie; Smith, Isabel; Mirenda, Pat; Roberts, Wendy; Volden, Joanne; Waddell, Charlotte; Szatmari, Peter – Journal of Child Psychology and Psychiatry, 2012
Background: Maximizing measurement accuracy is an important aim in child development assessment and research. Parents are essential informants in the diagnostic process, and past research suggests that certain parental characteristics may influence how they report information about their children. This has not been studied in autism spectrum…

Mirenda, Pat; Smith, Isabel M.; Vaillancourt, Tracy; Georgiades, Stelios; Duku, Eric; Szatmari, Peter; Bryson, Susan; Fombonne, Eric; Roberts, Wendy; Volden, Joanne; Waddell, Charlotte; Zwaigenbaum, Lonnie – Journal of Autism and Developmental Disorders, 2010
This study examined the factor structure of the Repetitive Behavior Scale-Revised (RBS-R) in a sample of 287 preschool-aged children with autism spectrum disorder (ASD). A confirmatory factor analysis was used to examine six competing structural models. Spearman's rank order correlations were calculated to examine the associations between factor…

Bennett, Terry; Szatmari, Peter; Bryson, Susan; Volden, Joanne; Zwaigenbaum, Lonnie; Vaccarella, Liezanne; Duku, Eric; Boyle, Michael – Journal of Autism and Developmental Disorders, 2008
Asperger syndrome (AS) is differentiated from high-functioning autism (HFA) largely on a history of "language delay." This study examined "specific language impairment" as a predictor of outcome. Language skills of 19 children with AS and 45 with HFA were assessed at 4-6 years of age (Time 1) and 2 years later (Time 2). Children's symptoms and…
