Exploration of potential preliminary screeners, and examination of social intervention outcomes for effects on comorbid symptoms is imperative. The Child Behavior Checklist (CBCL; Achenbach & Rescorla, Achenbach and Rescorla, Manual for the ASEBA school-age forms & profiles, University of Vermont, Research Center for Children, Youth &…

The Modified Checklist for Autism in Toddlers (M-CHAT) is a screening questionnaire for Autism Spectrum Disorder (ASD). Previous findings have confirmed the M-CHAT's sensitivity and specificity across several cultures, yet few studies have considered M-CHAT scores as a distributed trait in a sample of typical infants. The current study examined…

Psychiatric disorders in individuals with co-occurring autism spectrum disorders (ASD) and intellectual disability (ID) are common, but diagnosis presents many challenges. The Psychopathology in Autism checklist (PAC) is among the very few instruments specifically developed for this group of individuals. The psychometric properties of the PAC…

Here we report the results of the subgroup analyses of an observational cohort of children whose parents completed the Autism Treatment Evaluation Checklist (ATEC) over the period of several years. A linear mixed effects model was used to evaluate longitudinal changes in ATEC scores within different patient subgroups. All groups decreased their…

Psychiatric hospitalization of children with autism spectrum disorder (ASD) is common, but there is little comparative information available on different psychiatric hospital treatment models. Children with ASD ages 4-20 were enrolled upon admission to either a specialized (N = 53) or a general child psychiatric unit (N = 27). Caregivers completed…

Difficulty processing sensory information may impede progress in school for students with autism spectrum disorder (ASD). We explore the relationship between sensory processing and school performance in 26 high-functioning youths with ASD and 26 controls (age 8-14) using measures of sensory, social, cognitive, and academic functioning. In the ASD…

The Checklist for Autism Spectrum Disorder (CASD) completed by a psychologist (following standardized procedures integrating parent interview data, teacher report, and clinical observations) was compared with the CASD completed independently by mothers and teachers in 168 children with ASD and 40 with ADHD (1-12 years). The 30 CASD autism symptoms…

We examined the relationship between sleep duration and awakenings to Aberrant Behavior Checklist-Community (ABC-C) and Autism Diagnostic Observation Schedule (ADOS-2) scores in hospitalized youth with ASD and behavioral disturbance. Participants included 106 patients with a stay of at least 10 nights. Sleep in the hospital was recorded by staff…

Language abilities in adolescents with autism spectrum disorders (ASDs) are variable and can be challenging to ascertain with confidence. This study aimed to compare and evaluate different forms of language assessment: standardized language testing, narrative analysis and parent/teacher reports. 14 adolescents with ASD and 14 typically developing…

This study assessed the reliability and criterion-related validity of teacher ratings on the Adapted Skillstreaming Checklist for a sample of 133 children, aged 6-11 years, with autism spectrum disorder (without intellectual disability). Internal consistency for the total sample was 0.93. For a subsample, test-retest reliability was very good (r =…

The association between aberrant behaviour and depression was examined in a sample of 150 young males with Autism Spectrum Disorder via parent ratings on the Aberrant Behavior Checklist (ABC) and the Major Depressive Disorder subscale of the Child and Adolescent Symptom Inventory (CASI-4-D). Although several subscales of the ABC were significantly…

Sex differences in typical development can provide context for understanding ASD. Baron-Cohen ("Trends Cogn Sci" 6(6):248-254, 2002) suggested ASD could be considered an extreme expression of normal male, compared to female, phenotypic profiles. In this paper, sex-specific M-CHAT scores from N = 53,728 18-month-old toddlers, including n…

Children with autism spectrum disorder (ASD) tend to receive several related services during their early school years. In this study, we followed 70 preschoolers with ASD and used parent reports to document the intensity of these services over a 4-year period, in relation to children's outcomes in three domains. While behavioral difficulties…

To test the Child Behavior Checklist's (CBCL/1½-5) ability to screen for autism spectrum disorders (ASD), we studied Korean preschoolers: 46 with ASD, 111 with developmental delay (DD), 71 with other psychiatric disorders (OPD), and 228 non-referred (NR). The ASD group scored significantly higher than the other groups on the Withdrawn and…

The Aberrant Behavior Checklist (ABC) is a widely used measure in autism spectrum disorder (ASD) treatment studies. We conducted confirmatory and exploratory factor analyses of the ABC in 1,893 children evaluated as part of the Autism Treatment Network. The root mean square error of approximation was .086 for the standard item assignment, and in…
