IDS Publishing was incorporated in 1987 primarily to publish screening tools for people with a "dual diagnosis" (mental health disorders in people with mental retardation). The first standardized screening tool, the Reiss Screen for Maladaptive Behavior, was published in 1987, along with a non-standardized prior scale, Johnny Matson's Psychopathology Inventory for Mental Retardation (PIMRA). (IDS no longer publishes the PIMRA). These two tools became widely adopted and provided evidence that helped justify the creation of hundreds of new service programs and psychiatric clinics located throughout North America and elsewhere. The Reiss Screen was cited in prestigious research awards from the Arc of the United States, which at the time had 150,000 members, and the American Association on Mental Retardation. Many other measures were constructed by others but thus far all studies directly comparing the available tools shows that the Reiss Screen is unsurpassed for quick identification of people likely to need a specialized mental health service. In 1991 a child version of the Screen was published, called the Reiss Scales.
