Few studies investigate what members of the general population know about individuals with autism. Only one study has previously investigated how beliefs about autism differ from those about other psychiatric disorders. This study surveyed a convenience sample of the general adult population, within the Northern Region of Denmark, about their…

Bilker, Warren B.; Hansen, John A.; Brensinger, Colleen M.; Richard, Jan; Gur, Raquel E.; Gur, Ruben C. – Assessment, 2012
The Raven's Standard Progressive Matrices (RSPM) is a 60-item test for measuring abstract reasoning, considered a nonverbal estimate of fluid intelligence, and often included in clinical assessment batteries and research on patients with cognitive deficits. The goal was to develop and apply a predictive model approach to reduce the number of items…

Mandell, David S.; Lawer, Lindsay J.; Branch, Kira; Brodkin, Edward S.; Healey, Kristin; Witalec, Robert; Johnson, Donielle N.; Gur, Raquel E. – Autism: The International Journal of Research and Practice, 2012
This study estimated the ASD prevalence in a psychiatric hospital and evaluated the Social Responsiveness Scale (SRS) combined with other information for differential diagnosis. Chart review, SRS and clinical interviews were collected for 141 patients at one hospital. Diagnosis was determined at case conference. Receiver operating characteristic…

Moore, Raeanne C.; Viglione, Donald J.; Rosenfarb, Irwin S.; Patterson, Thomas L.; Mausbach, Brent T. – Psychological Assessment, 2013
Neurocognitive impairment and negative symptoms contribute to functional disability in people with schizophrenia. Yet, a high level of unexplained variability remains after accounting for the role of these factors. This study examined the role of thought disorder, psychological complexity, and interpersonal representations, as measured by the…

Whereas "Dysbindin" is considered a schizophrenia vulnerability gene, there is no consistency of findings. Phenotype refinement approaches may help to increase the genetic homogeneity and thus reconcile conflicting results. Premorbid adjustment (PMA) has been suggested to aid the phenotypic dissection.

fMRI Correlates of State and Trait Effects in Subjects at Genetically Enhanced Risk of Schizophrenia
Whalley, Heather C.; Simonotto, E.; Flett, S.; Marshal, I.; Ebmeier, K. P.; Owens, D. G. C.; Goddard, N. H.; Johnstone, E. C.; Lawrie, S. M. – Brain, 2004
Schizophrenia is a highly heritable disorder that typically develops in early adult life. Structural imaging studies have indicated that patients with the illness, and to some extent their unaffected relatives, have subtle deficits in several brain regions, including prefrontal and temporal lobes. It is, however, not known how this inherited…

Rojahn, Johannes; Matson, Johnny L.; Naglieri, Jack A.; Mayville, Erik – American Journal on Mental Retardation, 2004
Adults with predominantly severe and profound mental retardation (N = 180) who lived in a developmental center were assessed with the Behavior Problems Inventory and the Diagnostic Assessment for the Severely Handicapped-II.
