A growing body of research suggests that symptoms of autism spectrum disorder (ASD) may present differently in males and females. This study examined gender differences in ASD symptoms and developmental functioning, using the "Baby and Infant Screen for Children with aUtism Traits, Part 1" (BISCUIT-Part 1) and the "Battelle…

Dixon, Dennis R.; Jang, Jina; Chung, Kyong-Mee; Jung, Woo Hyun; Matson, Johnny L. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Identifying the function of behavior is crucial in formulating functionally-based treatment programs for people with challenging behaviors. The Questions About Behavior Function (QABF) is a well-established instrument with sound psychometric properties. The present study describes the development process for a Korean version of the QABF. The…

Neal, Daniene; Matson, Johnny L.; Belva, Brian C. – Research in Autism Spectrum Disorders, 2013
The "autism spectrum disorder observation for children" ("ASD-OC") is a newly created 54-item observation measure for autism spectrum disorders (ASD). Due to the fact that many of the ASD observation measures currently available do not have established psychometric properties and require extensive time and training to administer, the "ASD-OC"…

Horovitz, Max; Matson, Johnny L.; Hattier, Megan A.; Tureck, Kimberly; Bamburg, Jay W. – Journal of Mental Health Research in Intellectual Disabilities, 2013
Rates of challenging behaviors were assessed in 175 adults with intellectual disability (ID) or ID and a comorbid autism spectrum disorder (ASD). The relationship between ASD diagnosis, race, and challenging behaviors was assessed using the "Autism Spectrum Disorders-Behavior Problems for Adults (ASD-BPA)." Those with ASD and ID were…

Mahan, Sara; Matson, Johnny L. – Research in Autism Spectrum Disorders, 2011
Many children with Autism Spectrum Disorder (ASD) demonstrate challenging behaviors. Since challenging behaviors are obstacles for social development and learning, it is important to determine if and what challenging behaviors are exhibited. Although there are some measures that asses for challenging behaviors, the majority were not specifically…

Fitzgerald, Mary E.; Matson, Johnny L.; Barker, Alyse – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Seizures are more common in individuals with intellectual disabilities than in the general population. As a result, differences in functioning for individuals with intellectual disability with and without seizures have been evaluated. Research on differences in psychopathology for individuals with intellectual disability with and without seizures…

Matson, Johnny L.; Wilkins, Jonathan; Fodstad, Jill C. – Journal of Autism and Developmental Disorders, 2011
A top priority in the field of autism spectrum disorders (ASD) is the development of precise early diagnostic tools that can be completed with minimal time and training. We report on the convergent and divergent validity of the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT), specifically the BISCUIT-Part 1. Previous research with…

Matson, Johnny L.; Mahan, Sara – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
Antipsychotic drugs are the most frequently prescribed of the psychotropic drugs among the intellectually disabled (ID) population. Given their widespread use, efforts to systematically assess and report side effects are warranted. Specific scaling methods such as the "Matson Evaluation of Side Effects" ("MEDS"), the "Abnormal Inventory Movement…

Medeiros, Kristen; Kozlowski, Alison M.; Beighley, Jennifer S.; Rojahn, Johannes; Matson, Johnny L. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Previous research has found that individuals with intellectual disability and/or autism spectrum disorder (ASD), and those with greater symptom severity within these diagnoses, show higher rates of aggressive/destructive behavior, stereotypic behavior, and self-injurious behavior. In this exploratory cross-sectional study, toddlers at-risk for a…

Matson, Johnny L.; Mahan, Sara; Hess, Julie A.; Fodstad, Jill C.; Neal, Daniene – Research in Autism Spectrum Disorders, 2010
Previous studies analyzed the reliability as well as sensitivity and specificity of the Autism Spectrum Disorder-Diagnostic for Children (ASD-DC). This study further examines the psychometric properties of the ASD-DC by assessing whether the ASD-DC has convergent validity against a psychometrically sound observational instrument for Autistic…

Matson, Johnny L.; Fodstad, Jill C.; Rivet, Tessa T. – Journal of Intellectual & Developmental Disability, 2008
Background: Medication side-effects such as tardive dyskinesia (TD) are known to occur in individuals with a history of psychotropic drug use. This study aimed to contribute to the development of measures for assessing TD by examining the validity of the "Matson Evaluation of Drug Side-effects" (MEDS) with the "Dyskinesia…

Matson, Johnny L.; Gonzalez, Melissa; Wilkins, Jonathan – Research in Autism Spectrum Disorders, 2009
The Autism Spectrum Disorders-Diagnostic for Children (ASD-DC) is a 40-item Likert format scale designed to serve in the diagnosis of children and adolescents from 2 to 16 years of age. The reliability and factor structure of the scale have been established in previous research. Studies 1 and 2 were designed to evaluate the validity of the measure…

Sturmey, Peter; Laud, Rinita B.; Cooper, Christopher L.; Matson, Johnny L.; Fodstad, Jill C. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
Previous research has failed to address the possibility of behavioral equivalents in people with ID and mania. The relationship between a measure of mania and possible behavioral equivalents was assessed in 693 adults, most with severe or profound ID, living in a large residential setting. The mania subscale of the DASH-II proved to be a…

Sturmey, Peter; Laud, Rinita B.; Cooper, Christopher L.; Matson, Johnny L.; Fodstad, Jill C. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
Previous research has proposed behavioral equivalents for depression, but evidence for behavioral equivalents has been contradictory. The relationship between a measure of depression and several proposed behavioral equivalents of depression was assessed in 693 adults living in a large residential setting. Most were adults with severe or profound…

Matson, Johnny L.; Boisjoli, Jessica; Rojahn, Johannes; Hess, Julie – Research in Autism Spectrum Disorders, 2009
Autism Spectrum Disorders (ASD) are a group of neurodevelopmental disorders characterized by deficits in socialization, communication, and restricted interests and repetitive behaviors. In addition to these core deficits, individuals with ASD also experience co-occurring conditions such as problem behaviors. Problem behaviors are common to this…
