This instrument helps to diagnose mental disorders in persons
with IQs 60 to 80. The instrument consists of two checklists called
the "Ratings" and the "Self-Report" version, both
scored into DSM a priori categories.
CONCEPT:
The PIMRA is a checklist of psychopathological behaviors intended for
the assessment of psychiatric conditions in adolescents and adults
with mental retardation. The items, which are based on DSM-III, are
intended for people with mild or moderate mental retardation. The
PIMRA yields a total score as well as separate scores for Adjustment
Disorder, Affective Disorder, Anxiety Disorder, Inappropriate
Adjustment, Personality Disorder, Psychosexual Disorder,
Schizophrenia, and Somatoform Disorder.
ADMINISTRATION:
The PIMRA consists of two structured interviews. One interview is
conducted with a parent, teacher, caregiver, or work supervisor who
knows the subject well. The other interview is conducted with the
subject; of course, this self-report interview is not completed if
the subject is nonverbal or is unable to understand the questions.
The examiner should be a mental health professional who is familiar
with the basic concepts of psychopathology and who has experience
interviewing people with mental retardation. Ages: 16 & Up.
Administration time: 20 minutes.
RELIABILITY:
Norms were based on about 600 people with mental retardation using
three separate samples from Pennsylvania, Illinois, and Texas.
Subjects included outpatients from university-affiliated mental
health centers, residents of state schools and hospitals, and
participants in workshops. Internal consistency for the total score
estimated at .85.
VALIDITY:
Subjects with diagnosed psychopathology based on institutional
records had higher PIMRA total scores than subjects with no
psychiatric diagnosis, thus providing evidence for the criterion
validity of the total score. Total scores on the PIMRA and the
Checklist of Emotional Problems of Mentally Retarded Adults were
correlated at .83, thus providing evidence for the concurrent
validity of the PIMRA total score.
