ABSTRACT

The assessment of response-bias is critical in forensic psychological evaluations of alleged sex offenders because sex offenders frequently minimize psychopathology or personal limitations. This study tested predictions based on prior research that minimization on the Rorschach would be reflected by higher P, D, A, Lambda, and PER, and lower R, Blends, and Zf. We divided a sample of cleric and noncleric alleged sex offenders according to (a) whether they showed minimization on the MMPI, and (b) whether they admitted to their charges. We then compared these groups on the purported Rorschach validity indices. Our results do not support the use of any of these Rorschach scores in the assessment of minimization. We recommend that in forensic psychological evaluations, the Rorschach should not be used to assess defensiveness and is best used in combination with other psychometric instruments more sensitive to response-bias.

ABSTRACT

Sexual abuse in childhood is frequently reported among sex offenders and has been hypothesized to be one of a number of psychological factors etiologically related to perpetration of child molestation in adulthood. In the current study we examine a sample of cleric and noncleric admitted child molesters and normal control subjects in their exposure to sexual abuse in childhood and current psychopathology. Odds ratios for the association between exposure to sexual abuse and child molestation were obtained while adjusting for group differences in demographic and psychological characteristics. Results indicated exposure to sexual abuse in childhood was associated with becoming a child molester for both cleric and noncleric offenders (p < .0002). Nonclerics indicated more severe psychopathology than clerics. Sexual abuse in childhood is one of many risk factors for becoming a perpetrator of child molestation in adulthood for both cleric and noncleric child molesters. Noncleric offenders demonstrated more sociopathy and mental disorder in general while cleric offenders indicated more sexual conflictedness, suggesting different psychoetiologies of offending among cleric and noncleric child molesters.

ABSTRACT

Cleric sexual misconduct with minors is a problem receiving increased attention from the media, victims groups, and church authorities. Mental health professionals are increasingly being asked to assist church and civil authorities to help better understand the problem of cleric sexual misconduct with minors. In the current study we compared self-reported sexual functioning among cleric alleged child molesters, noncleric alleged child molesters, and normal control subjects. We hypothesized clerics would differ from nonclerics and normals in reported sexual functioning. Our sample included 30 Roman Catholic clerics and 39 nonclerics who were alleged to have engaged in sexual misconduct with minors, and 38 normal control subjects, all of whom took the Derogatis Sexual Functioning Inventory (DSFI) as part of their forensic psychiatric evaluation. Our results indicated clerics were more likely to report fewer victims, older victims, and victims of male gender than noncleric alleged child molesters. Clerics differed from nonclerics and normal control subjects on several dimensions of self-reported sexual functioning. Lower offense rate histories among clerics suggest that, as a group, clerics may be less seriously psychologically disordered than noncleric child molesters. Low DSFI scores among Roman Catholic clerics may be accounted for in part by their unique training and socialization process. Future studies should attempt to study the influence of social desirability on DSFI scores. Normative data from nonoffending celibate clergy are needed.

ABSTRACT

Can psychosis be faked on the Rorschach? We examined this question by comparing 2 groups of subjects with a high incentive to malinger, persons accused of serious crimes. All subjects were administered both the Minnesota Multiphasic Personality Inventory (MMPI) and the Rorschach and were assigned to honest (N = 35) and malingered (N = 13) groups on the basis of MMPI validity scales. The Rorschach protocols of these 2 groups were compared to assess how successfully malingerers could deliberately produce records that appeared psychotic on empirically derived Rorschach indices of psychosis. Despite an attempt to portray themselves as psychotic on the MMPI, subjects in the malingered group did not differ from honest responders on Rorschach variables that distinguish psychotic from nonpsychotic patients, but did differ in the number of dramatic responses produced. Our data suggest that the combination of the MMPI and Rorschach provides a powerful psychometric technique for detecting deliberate malingering of psychosis.

ABSTRACT

Sex offenders frequently show denial and distortion during forensic psychological evaluations, but research into assessment of rationalizations and cognitive distortions among sex offenders has been limited. We examined patterns of psychological distortion in 59 alleged child molesters. We compared fake-good and fake-bad orientations on the MMPI with psychological distortion on the Multiphasic Sex Inventory questionnaire which assesses various psychosexual characteristics among sex offenders. Analysis indicated that distortion on the Multiphasic Sex Inventory indices of minimization and exaggeration was significantly associated with response-bias on the MMPI. Cognitive-distortion indices were highly influenced by response-bias. Admitters differed from deniers on scales with items requiring admission or denial of offenses. Caution is warranted in clinical interpretation of the validity scales of this questionnaire, which are of limited utility for deniers. Subtle items on cognitive-distortion indices may be useful in assessment of those who deny and should be subjected to further research.

ABSTRACT

We administered the Buss-Durkee Hostility Inventory (Buss & Durkee, 1957) and the Minnesota Multiphasic Personality Inventory (Hathaway & McKinley, 1967) to 82 alleged child molesters. Denial of hostility was significantly associated both with minimization of psychopathology and with denial of charges of sex offense. No subjects who denied charges acknowledged psychopathology, whereas one third of admitters acknowledged psychopathology. Our results suggest that alleged sex offenders may show complex patterns of impression management and that self-report hostility inventories are highly vulnerable to response bias.

ABSTRACT

Although the MacAndrew Alcoholism scale is the most widely used Minnesota Multiphasic Personality Inventory (MMPI) measure of vulnerability to alcohol abuse, its accuracy has not been studied in patients intrinsically motivated to exaggerate or minimize psychopathology. We examined the usefulness of the MAC in predicting alcohol abuse in a forensic clinical sample. Results indicate the MAC (a) was not more effective than direct inquiry in this group, (b) scores were correlated negatively with minimization and positively with exaggeration for subjects with histories of alcohol abuse, (c) offered advantages over direct inquiry both in screening for alcohol history (sensitivity) and in confirming it (specificity), and (d) scores were only moderately more accurate in valid than in minimized or exaggerated MMPI protocols. The results suggest that clinicians should use the MAC cautiously, particularly when they suspect motivation to minimize psychopathology.

ABSTRACT

The evaluation of response bias (i.e., minimization or exaggeration) is central to forensic psychological evaluations. Yet few studies have assessed forensic samples to investigate the ability of psychological tests to detect response bias. We studied the relationship between the Sixteen Personality Factors Questionnaire (16PF) and the Minnesota Multiphasic Personality Inventory (MMPI) validity scales for 65 alleged sex offenders and assessed the effects of different cutoff scores for the 16PF validity scales. Results indicate consistent significant correlations between the validity scales of the 16PF and the MMPI for measures of minimization and exaggeration. use of a priori cutoff scores resulted in the classification of our sample in proportions parallel to those found in previous research for the 16PF Fake-Good scale but not the Fake-Bad scale. Our results indicate that 16PF validity scales are useful, but interpretations must take into account different base rates of response bias between sex offenders and the general population.

ABSTRACT

The possibility of fabricated or exaggerated organic deficits is a frequent concern in both civil and criminal forensic cases. Additionally, organic deficits may exist, but be incorrectly attributed to a claimed cause. Exaggeration or fabrication can apply to primary cognitive or emotional effects of brain damage or to secondary emotional effects. These categories of deficits, and their relationship to physical brain damage, must be clearly understood in order to comprehensively evaluate the possibility of malingering. This includes evaluation of different forms of consistency between (1) behaviors during evaluation, (2) claimed deficits and known organic syndromes, (3) behavior or claims during evaluation and actual life-functioning, and (4) test performance and known principles of cognitive functioning. Psychometric procedures and clinical strategies are described which can substantially aid in assessing consistency and distinguishing between honest and exaggerated self-reports. Limitations of available assessment techniques are described and a general decision model for evaluation of dissimulation of organic deficits is presented.

ABSTRACT

This research investigates the validity of the stereotype of insanity defendants as malingerers by analyzing the proportions of insanity defendants who exaggerate psychopathology at the pre- and postacquittal stages of the legal process and by assessing the severity of psychopathology among preacquittal defendants. We administered the Minnesota Multiphasic Personality Inventory (MMPI) to 49 insanity defendants evaluated for fitness to stand trial and/or sanity at the time of the alleged crime and to 52 subjects previously found not guilty by reason of insanity. Results indicated: (a) Contrary to the stereotype, a minority (14% to 41%) of insanity defendants clearly malingered, whereas 22% to 39% showed evidence of minimizing psychopathology. (b) Eighty-one percent of these subjects had MMPI profiles suggestive of psychosis, but relatively few showed evidence of primarily antisocial behavior. Thus, the malingering stereotype may be application to only a minority of insanity defendants and is specifically inapplicable to a substantial proportion who minimized psychopathology or showed evidence of psychosis consistent with the claim of insanity.

ABSTRACT

Despite the value of the MMPI to the forensic assessment of malingering (exaggeration) of psychopathology, few studies have assessed the accuracy of the MMPI validity scales in criminal forensic populations. We administered the MMPI to 35 insanity defendants undergoing evaluation for fitness to stand trial and/or sanity at the time of the crime, who stood to benefit from being assessed as psychologically disturbed, and 39 subjects previously found not guilty by reason of insanity (NGRI), who did not stand to gain from such an assessment, Insanity defendants showed significantly more malingering than NGRI subjects, p less than .05. Racial differences did not affect the data. These findings support the efficacy of MMPI validity scales in assessing malingering within criminal forensic groups, and support the generalizability of the scales across race.

ABSTRACT

Examined the RCRAS as an empirically based approach to insanity evaluations. Previous research has been encouraging with regard to the RCRAS' interrater reliability and construct validity. The present study, with a larger data base (N = 111), sought to cross-validate these findings. Results from five forensic centers established satisfactory reliability for the RCRAS (mean kappa r = .80 for decision variables for criminal responsibility) and differentiating patterns for four of the five scales between sane and insane patient-defendants. Results further suggested that the RCRAS was generalizable across age, sex, criminal behavior, and location of the forensic evaluation. These findings were discussed with respect to the potential clinical utility of the RCRAS.

ABSTRACT

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.

ABSTRACT

Forensic psychiatry and psychology, with an extensive history of clinical practice, is only recently emerging as a new scientific specialty. It is confronted with both general scientific-methodological issues, as well as unique, empirically-based psycholegal applications. Aimed towards a broader, more flexible paradigm for understanding the basis of our scientific inquiry, the paper examines various research and methodological issues. As a model for connecting and understanding these complicated and interrelated issues, Holton's explicit and useful model of scientific structure is provided. The methodology, logical and statistical analysis, and themata are explored with regards to their potential impact on scientific inquiry in forensic psychiatry. This paper argues for several considerations in furthering research. From a methodological basis, the prospective researcher has to consider (1) whether the methodology is, in part, predetermining the results; (2) whether the results are a prediction of the inclusion criteria rather than an independent finding; (3) what balance between specificity and generalizability is designed within the research study; and (4) what is the impact of various methodological artifacts on the results and conclusions of forensic psychiatric research (e.g., demand characteristics, evaluation apprehension, experimenter bias, systems influence). Further, the forensic psychiatric researcher is asked to consider the basis of the "validity" of his research findings in comparison with "objective reality" from the perspective of logical and statistical analysis. Scientists within forensic psychiatry are asked to consider (1) whether to employ "best fit" or complementarity in understanding their results; (2) how to make explicit the steps in data transformation and redefinition within their study; (3) what are the implications of exclusive use of null hypothesis testing in establishing research results; and (4) what is the comparative utility of non-parametric and multivariate statistical procedures in studying and understanding experimental variables. Finally, in acknowledging the non-linear and sometimes self-justifying aspect of science, researchers are invited to examine their basic assumptions, and the self-perpetuating and constraining nature of unacknowledged themata, as well as their impact on forensic psychiatry. This paper is conceptualized as a movement towards articulating both general methodological issues and their unique application to forensic psychiatry. The brief exposition of Holton's model and review of illustrative research in forensic psychiatry constitutes one attempt to strengthen the scientific rigor of forensic psychiatric research.
