The PIMRA was developed as a screening instrument to aid in the differential diagnosis of individuals with Intellectual Disability. It was the first standardized measure designed to assess psychopathology in individuals with intellectual disabilities. Parents/caretakers familiar with the individual rates each item. There are 56 items on the PIMRA representing seven classes of psychopathology based on DSM-III criteria (Schizophrenia, Affective Disorder, Psychosexual Disorder, Adjustment Disorder, Anxiety Disorder, Somatoform Disorder, and Personality Disorder) and one additional subscale measuring Inappropriate Adjustment. Sample items include: 'Person generally conforms well to rules and social situations'; 'Dependent, helpless, constantly seeking assurance or is vain or demanding'; 'Preoccupation with physical defects out of proportion with reality'; 'Decreased energy, mental and/or physical fatigue'; and 'Speech that is incoherent due to inability to put words together in a coherent sequence.'
