title: A trial use of some of Reitan's neuropsychological tests to assess mild organic complications in psychiatric patients.
abstract: Several testing procedures borrowed from Reitan's extensive investigations of impairment in brain function were employed in the present study (Tactual Performance Test, Trail Making Test, Seashore Rhythm Test, Speech Sounds Perception Test, Finger Oscillation Test). These tests were administer to three groups of Ss matched for age, education, and sex distribution. All Ss were 40 years of age or older. The groups were: hospitalized psychiatric patients suspected by their psychiatrists of some degree of organic impairment; hospitalized psychiatric patients not suspected of any organic impairment; and nonhospitalized, apparently normally functioning control Ss. Four months after the beginning of the study, the psychiatrists reevaluated and reclassified the patient Ss and formed new groups of those suspected and not suspected of organic impairment. A comparison of group means that used the original S groups showed that three of nine test scores were nondiscriminating, while the remaining six discriminated the control Ss from the patients, but not the two patient groups from each other. A similar comparison that used the revised patient groups formed from the psychiatrists' re-evaluations after an additional 4 months of observation yielded four test scores that discriminated successfully between the two patient groups: Tactual Performance Test, total time; Trail Making Test, Part A and Part B; and Finger Oscillation Test, right hand. These four test scores predicted the later classification of the patients more accurately than did the psychiatrists' own original evaluations, which would be in keeping with the general function of diagnostic testing, i.e., to provide initial information about patients beyond that which can be obtained from initial psychiatric examination.
