A DISCUSSION IS PROVIDED OF THE UTILITY OF SELECTED NEUROPSYCHOLOGICAL TESTS AND ASSESSMENTS IN PREDICTING OFFENDER RECIDIVISM AND DANGEROUSNESS AND IN IDENTIFYING SUBGROUPS WITHIN FORENSIC POPULATIONS.

Abstract

INITIAL ANALYSES WERE PERFORMED ON TWO SAMPLES OF FORENSIC PATIENTS AT ALBERTA HOSPITAL IN EDMONTON, CANADA, INCLUDING 108 PATIENTS WHO HAD BEEN REFERRED FOR PSYCHOLOGICAL TESTING AND 259 WHO HAD CRIMINAL RECORDS AND WERE RESIDENTS OF THE FORENSIC WARD. USING A LINEAR COMPOSITE OF 29 NEUROPSYCHOLOGICAL AND WECHSLER ADULT INTELLIGENCE SCALE VARIABLES, RESEARCHERS WERE NOT ONLY ABLE TO COMPARE DISCRIMINATIVE SUCCESS, BUT ALSO COULD COMPARE THE SPECIFIC TEST VARIABLES RELEVANT TO EACH DISCRIMINATION. WHEN SUBJECTS WERE CLASSIFIED AS RECIDIVIST AND NONRECIDIVIST ACCORDING TO THE SCALE, THE PREDICTIONS WERE 93 PERCENT CORRECT. WHEN THE OFFENDER POPULATION WAS BROKEN DOWN BY CRIME TYPE (VIOLENT OFFENSES, SEXUAL OFFENSES, AUTO THEFT, ETC.) AND CLASSIFIED IN TERMS OF SUGGESTED RECIDIVISM AND NONRECIDIVISM, THE OVERALL PREDICTION SUCCESS RATE WAS ALSO GOOD; 96 PERCENT OF DRUG OFFENSE RECIDIVISTS, 78 PERCENT OF PAROLE VIOLATION RECIDIVISTS, AND 79 PERCENT OF VIOLENT RECIDIVISTS WERE CORRECTLY PREDICTED. TABULAR DATA AND REFERENCES ARE PROVIDED. SEE ALSO NCJ-57488. (DAG)
