Rorschach comparisons of male juvenile sex offenders and nonsex offenders

Published research is limited on the psychological characteristics of juvenile sex offenders as a subgroup separate from other juvenile delinquents. This study compares 45 male adolescent sex offenders on the Rorschach with a matched group of nonsex adolescent offenders. The two groups differed in total number of responses. Eliminating those protocols of questionable validity due to low productivity in combination with a high lamba, a statistically significant difference in the number of anatomy responses given by the two groups was found. With this exception, the personality characteristics of adolescent sex offenders were similar to those of adolescents who commit only nonsexual crimes. It should be noted, however, that the scoring categories analysed were not exhaustive and that the groups may differ on more recently proposed Rorschach subscales.     

Attention and executive function deficits in adolescent sex offenders.

Thirty male adolescent sex offenders and 20 age-matched male adolescents completed an extensive battery of attention and executive function tests. Controls were obtained from adolescents from a socially and economically deprived background, typical of the offending group. The attention battery was based on Mirksy, Anthony, Duncan, Ahearn, and Kellam (1991) and the executive function battery on Kelly (2000a). Successful matching for IQ was not achieved and therefore ANCOVA comparisons were made between the groups, with IQ as the covariate. In attention a highly significant difference was found on the focus-execute factor and a significant difference on the shift factor. In executive function there was a highly significant difference only on the response speed factor. In all cases better abilities were demonstrated by the control group. The importance of thorough neuropsychological investigation in the clinical assessment of this forensic group is supported. The clinical implications of neuropsychological deficits in terms of risk assessment and clinical management are discussed.     

Factors associated with erection in adolescent sex offenders

A majority of adult child molesters report that their deviant interest began prior to the age of 18. This illustrates the need to evaluate adolescents who have molested children. Since self-report of deviant interest is rare in adolescent offenders, psychophysiologic assessment is necessary to help to determine the extent for a deviant interest pattern. The current study was designed to determine what factors are associated with erectile responding to age-inappropriate stimuli in an adolescent sex offender population. Factors studied were (a) admit/deny, (b) history of physical abuse, (c) history of sexual abuse, (d) history of nonsex arrests, and (e) incest/nonincest. The dependent variables were two pedophile indices, a relative measure of deviant to nondeviant arousal. Results indicated that history of sexual abuse was associated with more deviant erectile responding in those adolescents who had molested young boys. The possibility of adolescents modeling their own victimization is discussed.     

Prevalence of childhood and adolescent sexual abuse among sex offenders.

A simple nonstandardized questionnaire was developed and administered to 150 men convicted of various sexual offenses currently on probation or parole, living in the community, admitting their offenses and attending treatment. The hypothesis that men who engaged in sexual activity as adolescents with women would be at a higher risk of committing statutory rape-type sexual offenses was not substantiated.     

Characteristics of adolescent sex offenders: A review of the research

While significant research has been completed on adult sex offenders, this has yet to be the case for adolescent offenders. This article reviews current research on adolescent sex offenders, discusses the importance of research in this area, and describes directions for future study.     

Psychopathology of incarcerated sex offenders

The psychopathology and particularly the personality disorders of sex offenders were compared to general inmates of the Colorado Department of Corrections. Using the MCMI-III (Millon, 1994, 1997), sex offenders in general were found to have more varied types of personalities than general population inmates. Specifically, they were more schizoid, avoidant, depressive, dependent, self-defeating, and schizotypal. General population inmates had the more classically criminal personality characteristics of antisocial, narcissistic, and sadistic. Multivariate analysis showed the Dependent, Narcissistic, Antisocial, and Schizotypal scales to be the most differentiating. Sex offenders were also found to have more affective psychopathology such as anxiety, dysthymia, PTSD, and major depression. A similar trend was found when comparing child molesters to rapists. The child molesters were more neurotic, affective, and socially impaired than the rapists. Multivariate analysis showed the Dependent scale to be the most important in differentiating these two types of sex offenders.     

Denial and minimization among sex offenders

A review of empirical studies of offenders—particularly sex offenders, and more particularly those who offend against children—demonstrates that denial of offenses and minimization of offending behavior are quite common at every stage of the criminal justice process. This is true during police interviews, during pretrial and presentencing mental health evaluations, among incarcerated offenders, among offenders seeking treatment, among offenders facing parole review, and among offenders already released into the community. This review highlights gaps in the research literature arising from inconsistencies in the definitions and measurement of denial and minimization, from the stage of adjudication or treatment at which measurements are made, and from the use of polygraphy to increase disclosures. Despite these limitations on the generalizability of empirical findings, it appears beyond dispute that many sex offenders maintain their innocence in the face of evidence to the contrary or even criminal conviction, and that many are able to recite additional crimes they have committed when they believe it is in their self-interest to do so.     

The discriminative validity of a phallometric test for pedophilic interests among adolescent sex offenders against children

The authors examined the responses of adolescent sex offenders against children on a phallometric test of pedophilic interests. Participants were 40 adolescent sex offenders against children, 75 young adult sex offenders against children, and 39 young adult comparison participants. The responses of adolescents with female victims resembled those of comparison participants; adolescents with any male victims had larger relative responses to child stimuli than comparison participants. Young adult offenders, regardless of victim sex, had larger relative responses to child stimuli than comparison participants. Using a cut score of 0 (indicating equal or greater arousal to children than to adults), sensitivity was 42% for adolescents with any male victims, and specificity was 92% for the comparison participants. Results suggest phallometric testing can identify pedophilic interests among these adolescent sex offenders.     

Predicting recidivism in adolescent sexual offenders

The prediction of risk of sexual recidivism in adult sex offenders has been grounded on research identifying reliable markers or risk factors, the so-called static and dynamic variables. For adolescents such reliable factors in the prediction of risk of sexual recidivism have so far not been unequivocally revealed. The aim of this systematic review was to screen the available research literature for such factors. The results indicated that regarding static or historical risk variables some can be found repeatedly to be linked to sexual recidivism in adolescents such as previous offending and multiple or stranger victims. Considering dynamic variables there is much less documented evidence in the research literature possibly as a result of lack of adequate psychometric tools. Overall, regarding risk of sexual recidivism there continues to be a great need for research.     

Sex-role orientation and attachment styles of sex offenders

Given the increase of individuals who have a history of sexual offenses, there has been an increase in research on the etiology of sex-offending behavior. The present purpose was to evaluate the relationship between sex-role orientation and attachment styles of males who were sex offenders. Analysis yielded statistically significant differences between comparison (n = 22) and clinical groups (n = 21) in gender roles, with little sign of the androgynous gender type for sex offenders. The offender group showed significantly lower frequency of androgyny scores and significantly higher scores on feminine and undifferentiated orientations, supporting the theoretical view of sex offenders as being "cross-sex-typed." In addition, the sex offender group had a significantly higher mean score on anxious-avoidant relationship attachment. Based on the present findings, there appears to be a need to help sex offenders explore how their gender roles may relate to their sex-offending behavior and assist sex offenders in the development of adaptive relationships with reduced anxiety and ambivalence.     

Recidivism risk assessment in sex offenders

Violent behaviour risk assessment is one of the most relevant research areas in current Psychology of Crime. Various scales for violence risk assessment have recently been developed from research about crime careers and risk factors. One of these instruments is the Sexual Violence Risk Assessment-20 (SVR-20), translated and adapted to Spanish by the Group of Advanced Studies in Violence of the University of Barcelona. The goal of this study is to verify the predictive capacity of the SVR-20 to predict sexual violence recidivism in a Spanish sample of sexual offender inmates. The method used was a retrospective study based in 163 sexual offender files and a 4-year time lag. The data were analysed with the logistic regression technique. Of the sample, 79.9% non-recidivist individuals were correctly classified, and 70.8% recidivist individuals. The ROC curve obtained for the model shows a very good discriminant capacity for the SVR-20, with a 0.83 AUC value. The main conclusion of this study is that the Spanish adaptation of SVR-20 is a good instrument to predict the risk of sexual violence.     

Level of functioning and recidivism risk among adolescent offenders

The assessment of offending youth is important in determining the most appropriate disposition for adolescents involved in the justice system. Recent studies have found a relationship between justice system involvement and level-of-functioning (LOF). This study investigated the relationship between LOF and recidivism risk among adolescents involved in a community-based, juvenile justice treatment program. The results document that conceptually similar domains are substantively correlated; however, a range of functioning was found among youth considered to have the same risk of recidivism. Overall, the results suggest that LOF measures may be associated with risk measures due to a convergence of areas assessed and that the two constructs also may have a relationship analogous to LOF and clinical diagnosis.     

Salivary testosterone and cortisol among late adolescent male offenders

The relationship of salivary testosterone and cortisol concentrations to personality, criminal violence, prison behavior, and parole board decisions was examined among 113 late-adolescent male offenders. Offenders high in testosterone committed more violent crimes, were judged more harshly by the parole board, and violated prison rules more often than those low in testosterone. No main effects for cortisol emerged. However, as expected, a significant interaction between testosterone and cortisol was found, in which cortisol moderated the correlation between testosterone and violence of crime. Cortisol may be a biological indicator of psychological variables (e.g., social withdrawal) that moderate the testosterone-behavior relationship. Paper and pencil measures of personality and behavior showed little relationship to hormones.This research was supported in part by NIMH grant MH42525 and by a Vice-President's grant from Georgia State University. We wish to thank the Georgia Department of Corrections and the Georgia Board of Pardons and Paroles for making the research possible. In addition, we specifically extend thanks to Tim Carr (Department of Corrections); to Sue Aiken, Tom Morris, and Sheila Thompson (Board of Pardons and Paroles); and to Debra Plyler and Paula Williams for coding inmate records.     

MMPI-A performance of African and Mexican American adolescent first-time offenders

54 African and Mexican American adolescent first-time offenders were examined with the MMPI-A to evaluate ethnic differences. Multivariate analyses by ethnicity and MMPI-A scales (validity, clinical, content, and supplementary scales) were not significant; however, there was a significant univariate difference where African American adolescents scored significantly higher on the Repression scale than the Mexican American group. A greater percentage of within-normal-limits profiles were African American (50%) than Mexican American (25%). Research and clinical implications for using the MMPI-A with these groups are discussed.     

Lacking power impairs executive functions

Four experiments explored whether lacking power impairs executive functioning, testing the hypothesis that the cognitive presses of powerlessness increase vulnerability to performance decrements during complex executive tasks. In the first three experiments, low power impaired performance on executive-function tasks: The powerless were less effective than the powerful at updating (Experiment 1), inhibiting (Experiment 2), and planning (Experiment 3). Existing research suggests that the powerless have difficulty distinguishing between what is goal relevant and what is goal irrelevant in the environment. A fourth experiment established that the executive-function impairment associated with low power is driven by goal neglect. The current research implies that the cognitive alterations arising from powerlessness may help foster stable social hierarchies and that empowering employees may reduce costly organizational errors.     

Legal issues raised in treating sex offenders

For the past 50 years the criminal justice system has distinguished sex offenders from other criminals. This has resulted in their differential treatment, with the goal being to eliminate their inappropriate behavior. This article discusses the history and status of mentally disordered sex offender (MDSO) statutes. A review of the legal issues which arise when treating a sex offender without statutory authorization is provided. A discussion of problems raised in treating the offender on both an inpatient and outpatient setting is presented. The article concludes with an analysis of the legal problems confronting the treatment provider in working with this group of individuals.
