Linaker, Olav M.; Helle, Jon – Research in Developmental Disabilities, 1994

Comparison with a nonretarded population indicated that mentally retarded patients had less delusions and more incoherence and flat affect. They…

Matson, Johnny L.; Bamburg, Jay W. – Research in Developmental Disabilities, 1998
The initial psychometric properties of the Assessment for Dual Diagnosis (ADD), a new scale designed to screen for psychopathology in individuals with mild and moderate mental retardation, was examined. The ADD was found to have high stability across raters, high stability over time, and good internal consistency. (Author/DB)
