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"…

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…

Matson, Johnny L.; Horovitz, Max; Mahan, Sara; Fodstad, Jill – Research in Autism Spectrum Disorders, 2013
The purpose of this paper was to update the psychometrics of the "Matson Evaluation of Social Skills for Youngsters" ("MESSY") with children with Autism Spectrum Disorders (ASD), specifically with respect to internal consistency, split-half reliability, and inter-rater reliability. In Study 1, 114 children with ASD (Autistic Disorder, Asperger's…

Matson, Johnny L.; Cervantes, Paige E. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
The Matson Evaluation of Drug Side Effects (MEDS) is currently the best established and most researched measure of drug side effects in the intellectual disability (ID) literature. Initial research was conducted on its psychometric properties such as reliability and validity. More recent research studies have used the measure to determine the…

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.; Neal, Daniene; Hess, Julie A.; Kozlowski, Alison M. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
A lack of toileting skills is one of many impairments that individuals with intellectual and developmental disabilities experience. Unfortunately, little research has focused on problems in this area including assessment, function, and treatment. A newly developed checklist, the "Profile of Toileting Issues" ("POTI"), is being considered for use…

Matson, Johnny L.; Neal, Daniene; Fodstad, Jill C.; Hess, Julie A.; Mahan, Sara; Rivet, Tessa T. – Behavior Modification, 2010
Social skills are an important part of development, and deficits in this area have long-term impacts on a child. As a result, clinicians should include a measure of social skills as part of a comprehensive assessment. There are a few well-researched measures of social skills that are currently used, including the Matson Evaluation of Social Skills…

Garcia, Mark J.; Matson, Johnny L. – Journal of Intellectual & Developmental Disability, 2008
Background: This study assessed the psychometrics of two measures--the "Matson Evaluation of Drug Side-effects" (MEDS) and the "Akathisia Ratings of Movement Scale" (ARMS)--and examined the symptom profile of akathisia in a sample of people with intellectual disability (ID). Method: Sixty-six participants formed three groups of…

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.; Gonzalez, Melissa L.; Wilkins, Jonathan; Rivet, Tessa T. – Research in Autism Spectrum Disorders, 2008
The reliability of a new scale to assess Autistic Disorder, Pervasive Developmental Disorder, Not Otherwise Specified (PDD-NOS), and Asperger's Disorder in children was examined. Parents or other caregivers rated symptoms of 207 children between 2 and 16 years of age. The scale, which had 40 items in the final version, correlated highly with…

Matson, Johnny L.; Wilkins, Jonathan – Behavior Modification, 2009
The assessment of maintaining variables with the goal of developing prosocial intervention plans has become a driving force in the intellectual disabilities (ID) literature. One particularly crucial variable is whether the behavior is low or high rate and whether the challenging behavior is best characterized by self-injury or aggression. Because…

Singh, Ashvind N.; Matson, Johnny L.; Mouttapa, Michelle; Pella, Russell D.; Hill, B. D.; Thorson, Ryan – Research in Developmental Disabilities: A Multidisciplinary Journal, 2009
Due to the relative inability of individuals with intellectual disabilities (ID) to provide an accurate and reliable self-report, assessment in this population is more difficult than with individuals in the general population. As a result, assessment procedures must be adjusted to compensate for the relative lack of information that the individual…

Matson, Johnny L.; Boisjoli, Jessica A. – Behavior Modification, 2008
Social skills are defining aspects of intellectual disability (ID). Additionally, their presence or absence can be a major impediment to independent living, and they correlate with other problems in the ID population, such as comorbid psychopathology. To date, little has been done to develop scales to measure these problems, particularly for…

Gonzalez, Melissa L.; Dixon, Dennis R.; Rojahn, Johannes; Esbensen, Anna J.; Matson, Johnny L.; Terlonge, Cindy; Smith, Kimberly R. – Journal of Applied Research in Intellectual Disabilities, 2009
Background: The aim of this study was to reevaluate the reliability (internal consistency, inter-rater and re-test) and the factor structure of the Behavior Problems Inventory (BPI-01) with adults with intellectual disabilities who resided in a state-run developmental centre. Methods: BPI-01 was administered to informants who had known…

Matson, Johnny L.; Wilkins, Jonathan; Sevin, Jay A.; Knight, Cheryl; Boisjoli, Jessica A.; Sharp, Brenda – Research in Autism Spectrum Disorders, 2009
The success of early intervention programs has in large part spurred increasing emphasis on identifying children with autism and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) at the earliest possible ages. National and international professional groups have called for early screening and diagnosis, yet the technology to…
