The Adapted Skillstreaming Checklist measures social/social-communication skills and behavioral flexibility/regulation of children with autism spectrum disorder without intellectual disability. Prior studies provided support for the reliability and criterion-related validity of the Adapted Skillstreaming Checklist total score for these children;…

Previous research supports the CBCL/1½--5's "DSM"-ASD scale (and its precursor, the "DSM"-PDP scale) as a Level 1 ASD screener. Confirmatory factor analyses (CFAs) with data from population samples in 24 societies (N = 19,850) indicated good measurement invariance across societies, especially for configural and metric…

The validity, reliability and factor structure of the Autism Spectrum Disorder Behaviour Checklist-Revised (ASDBC-R) were measured in a sample of 140 boys with Autism Spectrum Disorder (ASD) aged between 6 and 18 years. Internal consistency (Cronbach's alpha) was satisfactory and the ASDBC-R significantly correlated with the Social Responsiveness…

The purpose of this study was to identify how parents' use of language and literacy strategies during an adapted shared book reading activity relate to social, behavioral, and cognitive skills for their children with autism spectrum disorder (ASD). Participants were 111 young children (ages 4-7 years) with ASD and their mothers. A factor analysis…

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…

Individuals with an autism spectrum disorder (ASD) often present with co-occurring emotional and behavioral disorders (EBD). The Child Behavior Checklist 6-18 (CBCL; Achenbach & Rescorla, 2001) is an EBD measure that contains several norm-referenced scales derived through factor analysis of data from the general pediatric population. The…

The number of young children with autism is ever-increasing, and school psychologists are more frequently required to identify these students. Valid screening tools are needed in order to focus school psychologists' time on those students in need of intensive evaluations in Early Intervention programs. The purpose of this study was to examine the…

Background: Presence of an autism spectrum disorder is a risk factor for development of self-injurious behaviour (SIB) exhibited by individuals with developmental disorders. The most salient SIB risk factors historically studied within developmental disorders are level of intellectual disability, communication deficits and presence of specific…

Previously, we adapted the Home Situations Questionnaire to measure behavioral non-compliance in everyday settings in children with pervasive developmental disorders. In this study, we further revised this instrument for use in autism spectrum disorder and examined its psychometric properties (referred to as the Home Situations…

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…

Children with mild developmental disorders sometimes show giftedness. In this study, an original checklist was developed to identify gifted characteristics specific to science learning among twice-exceptional primary school children in Japan. The checklist consisted of 60 items on Attitudes, Thinking, Skills, and Knowledge/Understanding. A total…

Validity studies of measures for emotional and behavioral disorders (EBD) for use with preschool children with autism spectrum disorders (ASD) are lacking. The Child Behavior Checklist 1.5-5 (CBCL; Achenbach and Rescorla, Manual for the ASEBA Preschool Forms & Profiles. VT: University of Vermont, Research Center for Children, Youth, and…

This study investigated whether the Communication Checklist-Adult (CC-A) could identify subtypes of social and communication dysfunction in autism probands and their parents. The CC-A is divided into subscales measuring linguistic ability as well as two aspects of social communication: the Pragmatic Skills subscale assesses the level of pragmatic…

Background: A number of disorders are associated with pragmatic difficulties. Instruments that can make subdivisions within the larger construct of pragmatics could be important tools for disentangling profiles of pragmatic difficulty in different disorders. The deficits underlying the observed pragmatic difficulties may be different for different…
