The Study of Multiple Murder Preliminary Examination of the Interface Between Epistemology and Methodology

Cases of multiple murder stimulate intense feeling in both the public and scientific community. Because of this highly charged emotional climate and the statistical difficulties inherent in predicting low base rate behaviors, this topic has been difficult to evaluate scientifically. This article reviews the literature on multiple murder from dual perspectives of how knowledge is developed and major methodologic problems encountered in accruing such knowledge.

Psychopathology and denial in alleged sex offenders

To investigate whether patients accused of having committed acts of sex offense manifest symptoms of psychopathology and whether they minimize or deny such symptoms during clinical evaluations, we administered the MMPI to 53 alleged sex offenders. We compared patients along two dimensions: a) whether they admitted or denied deviant sexual behavior, and b) whether they faced legal charges for sex offenses. Results indicated the following: a) Patients who denied deviant sexual behavior were significantly more likely to minimize psychopathology than were those who admitted to deviant sexual behavior (p<.05). b) Patients facing no active legal charges showed significantly more psychopathology than did those facing legal charges (p<.05). c) The most frequent forms of psychopathology shown by these patients were antisocial attitudes, depression, somatization, and cognitive disorganization. These findings suggest that many alleged sex offenders may experience, and deny, severe psychopathology in addition to their sexual disorders. Clinicians should be alert to subtle signs of psychopathology when evaluating alleged sex offenders who deny deviant sexual behavior, because these patients may be especially likely to minimize symptoms.

Do Sex Offenders Minimize Psychiatric Symptoms

With increasing frequency, forensic psychiatrists are called upon to evaluate sex offenders for the courts and criminal justice system. While many clinicians have observed that denial of paraphilia is common in sex offenders, few studies have examined whether this population has severe psychopathology other than paraphilia. Similarly, little is known about whether sex offenders minimize or deny symptoms of psychopathology when undergoing psychiatric evaluations. To study these questions, the authors administered the Minnesota Multiphasic Personality Inventory (MMPI) to 36 sex offenders, comparing the degree to which they minimized or denied psychopathology, dividing subjects among two dimensions: (a) whether they admitted to, or denied, paraphilia, and (b) whether or not they faced legal charges for sex offense. Results indicated that, first, patients who denied paraphilia were significantly more likely to minimize psychopathology than were those who admitted to paraphilia (P less than 0.05); second, patients who faced no legal charges showed significantly more psychopathology than did those who faced charges (P less than 0.05); and third, the most frequent forms of psychopathology were antisocial attitudes, depressive features, somatization, and thought disorder. These findings suggest that many sex offenders may experience, and deny, widespread and severe psychiatric symptoms in addition to their sexual disorders.

Adjustment of the Not Guilty by Reason of Insanity (NGRI) Outpatient: An Initial Report

Adjustment to outpatient treatment of not guilty by reason of insanity (NGRI) patients following discharge from inpatient settings was explored by following 44 subjects in a 2-year, longitudinal study. Data obtained for each subject included demographic characteristics, Schedule for Affective Disorders and Schizophrenia-Research Diagnostic Criteria (SADS-RDC) diagnosis, and Minnesota Multiphasic Personality Inventory (MMPI). Repeated measures included the Schedule for Affective Disorders and Schizophrenia-Change Form (SADS-C), Symptom Checklist 90 (SCL-90), and Holmes ahe Inventory. No recidivism occurred for any crime against persons, 25% of subjects were rehospitalized, and those subjects remaining in outpatient treatment showed a general pattern of stable to modestly improving functioning. Implications for safe and effective community treatment of NGRI acquittees are discussed.

Validation of police officer recruit candidates' self-reported drug use

Three hundred and fifty-nine Chicago Police Department recruit candidates submitted urine specimens as part of a drug-screening program. Candidates were tested in two groups about a week apart. About 20% of the recruit candidates in each group evidenced drug, primarily marijuana use. As part of a psychological screening test battery all the candidates also took the Inwald Personality Inventory (IPI). The IPI contains a self-report Drug Use Scale. Drug-Positive and Drug-Negative candidates Drug Use Scale scores were matched by age, sex, and racial/ethnic group and compared to evaluate the accuracy of self-reported drug use when screening police recruit candidates. Results showed that Drug-Positive candidates self-reported drug use was consistently higher than that of Drug-Negative candidates. Item-level analyses showed which drug use items best discriminate between Drug-Positive and Drug-Negative candidates. Implications are drawn for use of self-report as part of a police candidate screening process.

A Computerized Assessment Program for Forensic Science Evaluations: A Preliminary Report

The development of the innovative use of an on-line, computer-assisted evaluation program is discussed, with a brief review of pertinent literature. The particular applications within a forensic psychiatric center of the Tandem 16 computer system, utilizing both canned psychological tests and specialized assessment techniques, are examined and highlighted with a case vignette. A highly relevant problem within forensic psychiatry, malingering or exaggeration of symptoms, is examined in more detail as it relates to computer assessments. The advantages and limitations of a computer-assisted evaluation are described relative to both its clinical and research application.
