Matson, Johnny L.; LoVullo, Santino V.; Rivet, Tessa T.; Boisjoli, Jessica A. – Research in Autism Spectrum Disorders, 2009
A limited number of studies currently exist focusing on comorbid psychopathology of children with autism spectrum disorders (ASDs). Due to the heterogeneity of ASD symptoms, communication deficits, and impairments in intellectual functioning, assessing symptoms of psychopathology is complicated. The "Autism Spectrum Disorders-Comorbidity for…

Matson, Johnny L.; Boisjoli, Jessica A. – Journal of Intellectual & Developmental Disability, 2007
Background: The "Questions About Behavioral Function" (QABF) correctly identifies maintaining variables of challenging behaviour. However, for adults who have a long history of challenging behaviours, identifying one clear function of the maladaptive behaviour is difficult. Additionally, the person may develop multiple functions of their…

A Comparison of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) and the Aberrant Behavior Checklist (ABC).
Peer reviewed Peer reviewed
Paclawskyj, Theodosia R.; Matson, Johnny L.; Bamburg, Jerald W.; Baglio, Christopher S. – Research in Developmental Disabilities, 1997
A study of 233 individuals with severe mental retardation examined the validity of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) through correlation with the Aberrant Behavior Checklist (ABC). DASH-II as a whole was found to have a high degree of convergent validity with the ABC total score. (CR)

Validity of the Mania Subscale of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II).
Peer reviewed Peer reviewed
Matson, Johnny L.; Smiroldo, Brandi B. – Research in Developmental Disabilities, 1997
A study tested the validity of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) for determining the presence of mania (bipolar disorder) in 22 individuals with severe mental retardation. Results found the mania subscale to be internally consistent and able to be used to classify manic and control subjects accurately. (Author/CR)

Matson, Johnny L.; Mayville, Erik A.; Bielecki, JoAnne; Barnes, W. Harvin; Bamburg, Jay W.; Baglio, Christopher S. – Research in Developmental Disabilities, 1998
A study involving 200 adults with mental retardation investigated the interrater reliability and internal consistency of the Matson Evaluation of Drug Side Effects (MEDS), a scale designed to evaluate commonly identified side effects with a psychometrically sound checklist. The MEDS had excellent consistency across raters and good internal…

Matson, Johnny L.; Laud, Rinita B.; Gonzalez, Melissa L.; Malone, Carrie J.; Swender, Stephen L. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2005
The use of anti-epileptic medications (AEDs) is much higher in individuals with intellectual disabilities than in the general population. As many of these individuals rely on such medications, clinicians should consider psychometrically sound instruments for assessing adverse side effects of these medications as one aspect of routine clinical…
