Statistical Adequacy of the Abel Assessment for Interest in Paraphilias

A review of the psychometric properties of the Abel Assessment for Interest in Paraphilias (AAIP) is presented. The data supporting the AAIP's history, purpose, data, reliability, validity, and norms are reported, with the conclusion that its use with adults is tenuous at best and its use with adolescents is as yet unsupported. Pragmatic concerns are noted, along with recommendations for further research.     

Use of Physical Force as an Offense Characteristic in Subtyping Juvenile Sexual Offenders

Juvenile sexual offenders were grouped based on whether they had ever used physical force or threats of force to commit an offense using self-reports on the Multiphasic Sex Inventory (MSI) and clinical records review. Subjects were 101 male offenders, 12 to 19 years, residing at a residential treatment facility. Cross-tabulation of self-report and records review were done to define three groups of offenders: rapists (i.e., those who used force), nonrapists, and deniers. These three groups were compared using the MSI and Jesness on other variables assessing offense patterns, sexual deviance, delinquent attitudes, perceived social competence, and offense-related cognitions. Rapists reported significantly more sexual assault fantasy/predatory behavior, greater preoccupation with children, and more paraphilias than did nonrapists and deniers. In comparison to deniers, rapists also reported more obsessive thinking about sex, and a greater willingness to participate in treatment. These findings are discussed with a focus on the apparent validity and usefulness of subtyping juvenile offenders based on whether or not they have used physical force or threats of force in committing a sexual offense.     

Developmental Antecedents of Sexual Coercion in Juvenile Sexual Offenders

Previous research has linked adult sex offending behavior to a multiplicity of variables, including juvenile delinquency and the experience of childhood abuse. The purpose of this study was to explore developmental pathways among childhood abuse, juvenile delinquency, and personality dimensions possibly conducive to adolescent sexual coercion. Using a retrospective self-report inventory, we measured the extent to which juvenile sexual offenders experienced childhood trauma, engaged in adolescent delinquency, and exhibited particular dispositions and cognitive biases. The effects of childhood and adolescent antecedents on sexual coerciveness were then analyzed through simultaneous multiple regression path analyses. Results suggest that sexual compulsivity and hypermasculinity, through misogynistic fantasy behavior, significantly discriminate verbally and physically coercive juvenile offenders from those offenders who do not report using force in their offenses. Results also suggest that alcohol abuse may play a more salient role in the expression of coercive juvenile sexual coercion than previously hypothesized.     

Comparison of Perpetration Characteristics Between Male Juvenile and Adult Sexual Offenders: Preliminary Results

This study investigated the characteristics of the sexual abuse perpetrated by 16 juvenile (JSO) and 19 adult sexual offenders (ASO). Data were collected from a randomly selected group of males who received psychotherapy services at a community agency. The results revealed significant differences between the JSOs and the ASOs on the number of committed offenses, length of sexual relationships maintained with victims, quality of these relationships, nature of the sexual acts committed, and presence of force during abuse incidents. The results show similarities and differences in the sexual abuse characteristics perpetrated by juveniles and adults.     

Sex As a Coping Strategy and Its Relationship to Juvenile Sexual History and Intimacy in Sexual Offenders

The current research examined the hypothesis that sexual activity functions as a coping strategy for sexual offenders. A 16-item scale, the Coping Using Sex Inventory (CUSI), was developed to assess the presence of and the degree to which sex was used to deal with problematic situations. Sexual offenders consistently reported, using sexual activities, both consenting and nonconsenting, as a coping strategy to deal with stressful and problematic situations. In the first study, when compared to nonsexual violent offenders, sexual offenders showed evidence of sexual preoccupation during adolescence, and this preoccupation was related to the latter use of sex as a coping strategy. In the second study, intimacy deficits and loneliness were related to greater use of sexual activity as a coping mechanism. The third study examined the psychometric properties of the CUSI. A factor analysis revealed 3 factors in the CUSI corresponding to consenting sexual themes, rape themes, and child sexual abuse themes. Sexual offenders reported higher use of each type of sexual activity to cope with stressful and difficult situations as compared to nonsexual offenders. Theoretical and clinical implications are discussed here.     

Factors Associated with Treatment Compliance in a Population of Juvenile Sexual Offenders

Structural equation modeling was utilized to assess predictors of outcomes in a sample of 204 juvenile male sexual offenders participating in community-based treatment programming. Lower levels of client denial at intake predicted successful program compliance. Higher levels of denial were found in nonadjudicated youths. Although program attrition was high (50% in the first year), relatively few youths were expelled for sexual (4.9%) or nonsexual delinquency (6.6%) over a 12- to 24-month period. Program failure during years 1 and 2 was attributable largely to expulsion for failure to comply with attendance requirements and/or therapeutic directives. Youths failing to comply were found to have higher overall levels of measured sexual maladjustment and may be at greater long-term risk for sexual recidivism. Implications of the findings for clinical risk assessment, and directions for future research, are discussed.     

Comparison of Two Risk Assessment Instruments for Sexual Offenders

The current research examines the predictive validity of the Static-99 and the SORAG in predicting sexual and violent recidivism among a sample of 258 treated high-risk sexual offenders. While the SORAG was found to have moderate predictive accuracy for both sexual and violent recidivism over a 5-year follow-up period, the Static-99 was found to only predict sexual recidivism. As well, the actual recidivism rates in the current sample were compared to the published risk percentages for each of the instruments. For both the Static-99 and the SORAG the current sample re-offended at a lower rate than expected. Possible explanations for this finding are discussed.     

Predictors of Recidivism in Australian Juvenile Sex Offenders: Implications for Treatment

Juvenile sex offenders charged with their first sexual offence were compared with recidivist juvenile sex offenders who had been charged with more than one sexual offence on a number of factors related to sexual offending. Participants were 70 male juvenile sex offenders, aged 13–21 years who were awaiting court disposition. Negative family history, negative family characteristics, school and learning problems, social skill deficits, deviant sexual experiences, deviant sexual fantasies, and cognitive distortions were assessed for their direct and mediating roles in recidivism. Path analysis indicated that poor social skills, learning problems, and deviant sexual experiences were causally related to recidivism of sexual offending. Poor social skills were directly related to recidivism, whereas cognitive distortions and deviant sexual fantasies mediated the role of learning problems and deviant sexual experiences. There was a significant association between deviant sexual experience and learning problems. The findings support the role of cognitive distortions and deviant sexual fantasies in recidivist sexual offending for this sample. The causal role identified for poor social skills and learning problems in recidivism for sexual offending has implications for treatment and therefore deserves further attention.     

Violent Juvenile Sex Offenders Compared with Violent Juvenile Nonsex Offenders: Explorative Findings From the Pittsburgh Youth Study

Only a limited number of studies have compared the psychosocial characteristics of juvenile sex offenders and nonsex offenders. The results of these studies have often been contradictory. Furthermore, studies in normal population groups are rare and most of those studies have been conducted in specific populations. This paper reports on the findings of a prospective, longitudinal study, the Pittsburgh Youth Study, in which violent male sex offenders (n = 39) were compared with violent nonsex offenders (n = 430) based on 66 demographic and psychosocial characteristics. The findings show that the sex offenders resembled the nonsex violent offenders with respect to nearly all child, family, peer and demographic risk factors. Some suggestions are made with regard to future research.     

Methodological Issues Concerning Evaluation of Treatment for Sexual Offenders: Randomization,Treatment Dropouts,Untreated Controls,and Within-Treatment Studies

The value of randomized controlled trials in evaluation of sexual offender treatment has been questioned. Concern was expressed that randomization fails to produce equivalent samples, without apparent appreciation this is inevitable when variables are distributed by chance; lack of equivalence is controlled by use of tests of significance. A further uncriticized and inappropriate procedure in treatment evaluation is separation of the results of subjects who did not complete treatment from those who did, when the outcome of the former group was known. Despite an APA Task Force recommendation, no attention has been given to the consistent finding that no treatment is less effective than placebo psychological therapies. The significance of Type II errors is discussed and the recommendation criticized that within-treatment research be encouraged as an alternative to outcome research. Demonstrating a within-treatment response when that response is associated with a better outcome does not necessarily mean that the treatment was effective. Subjects with a good prognosis could be more able to demonstrate a within-treatment response to the treatment. Nonrandomized matched samples do not adequately control all sample differences. The post hoc statistical reversal of a reported trend for sexual offenders treated with relapse prevention to show a worse outcome than untreated offenders, in order to correct lack of equivalence of the two groups, is considered inappropriate. That relapse prevention was found less effective than no treatment raises the possibility that it has a negative effect. To continue the use of relapse prevention other than in randomly controlled evaluative studies would appear to be unethical.     

Sexual Deviance and Number of Older Brothers Among Sexual Offenders

A number of studies have shown that the probability that a man is homosexual increases with the number of older brothers (but not sisters) bom to his mother. This older brother effect suggests that a progressive maternal immunosensitization process is involved in producing homosexual preferences. A recent demonstration of the older brother effect in homosexual pedophilia raises the question of whether it is involved in other anomalous sexual preferences as well. In the present study, phallometric data were gathered from 29 child molesters, 38 rapists, and 11 individuals who had offended against both children and adults. In all groups, a phallometric index of sexual deviance (a relative preference for children or for coercive sex) was positively correlated with the offenders' number of older brothers (but not sisters). These results suggest that the maternal immunosensitization hypothesis may explain some variations in male sexual preferences.     

Juvenile Sex Offenders: Toward the Development of a Typology

Adolescent males who sexually offended against prepubescent children were contrasted with those who targeted pubescent and postpubescent females. As hypothesized, path analyses revealed that the former group had greater deficits in psychosocial functioning, used less aggression in their sexual offending, and were more likely to offend against relatives. Theorized relationships between developmental risk factors, personality mediators, and sexual and nonsexual offense characteristics were assessed in both groups of juvenile sex offenders. Deficits in psychosocial functioning were found to mediate the influence of childhood exposure to violence against females on adolescent perpetration of sexual and nonsexual offenses. Additional univariate analyses were conducted to further explore some associations among early risk factors, personality mediators, and outcomes. Childhood physical abuse by a father or stepfather and exposure to violence against females were found to be associated with higher levels of comorbid anxiety and depression. Noncoercive childhood sexual victimization by a male nonrelative was found to be associated with sexual offending against a male child. Clinical and theoretical implications of the findings are discussed.     

An Exploration of Factors Related to Deviant Sexual Arousal Among Juvenile Sex Offenders

To date, there has been limited literature on the measurement of sexual arousal in adolescent sex offenders. The data that exist have been somewhat mixed in terms of factors related to deviant sexual arousal in this group. The present study, with 71 adolescent sex offenders, investigates the relationship between offender and offense characteristics, including gender of victim, history of sexual abuse, history of physical abuse, race, and interactions between these factors in the prediction of physiologically measured sexual arousal to deviant and nondeviant stimulus categories. A number of variables significantly predicted sexual arousal. The most consistent predictors were gender of victim, race, the interaction of race and gender of victim, and to some extent the interaction of offender abuse history and gender of victim. Caucasian subjects tended to respond more than African American subjects did, and this has not been reported previously in the literature. The data are discussed in terms of consistency with other literature, suggesting that those juvenile offenders who target male victims and have been abused themselves may be a high risk group. Limitations of this study are also addressed.     

Trait Empathy and Criminal Versatility in Sexual Offenders

Associations between trait empathy and criminal versatility were examined in a sample of 88 incarcerated adult sexual offenders (29 extrafamilial child molesters, 26 intrafamilial child molesters, and 33 rapists). Considerable criminal versatility was observed, with 60% of the whole sample and 88% of recidivist offenders having previous convictions for nonsexual offenses. Regression analyses showed significant associations between trait empathy and nonsexual offense convictions, but not between trait empathy and sexual offense convictions. More specifically, greater involvement in violent offending (e.g., assault, robbery) was associated with lower levels of empathic concern and higher levels of fantasy. Greater involvement in miscellaneous (e.g., traffic, drug, public order) offending was associated with lower levels of empathic concern. We argue that insufficient theoretical and empirical attention has historically been given to criminal versatility among sexual offenders, especially among child molesters. In particular, we suggest that developments in empathy training for sexual offenders may benefit from distinguishing needs of criminally versatile and non-versatile sexual offenders. More knowledge about trait empathy in sexual offenders, and about situational factors that may override otherwise normal empathic responsiveness, is needed.     

Juvenile female sexual offenders: Clinical characteristics and treatment issues

The phenomenon of juvenile female sexual offending was explored through the study of 67 youths who had been referred for either community-based or residential treatment following a documented history of sexual perpetration. These youths were compared to a group of 70 juvenile male sexual offenders across three parameters: developmental and psychiatric characteristics, history of maltreatment, and sexual perpetration characteristics. Relative to the juvenile males, the histories of the studied females reflected even more extensive and pervasive childhood maltreatment, with many of the youths exposed to the modeling of interpersonal aggression by females as well as males. The majority of these juvenile female sexual offenders demonstrated repetitive patterns of sexual offending with multiple victims, suggesting psychosexual disturbances equivalent in severity to the comparison group of males. The authors discuss typological impressions of this clinical population and their special treatment needs.     

Psychiatric Disorders and Recidivism in Sexual Offenders

Research on psychiatric morbidity in sexual offenders (SOs) has mostly been based on small, selected samples. We studied psychiatric disorders and their relationship with criminal recidivism in a nationwide, representative cohort of SOs. Data on ICD-9 and -10 psychiatric and neurologic morbidity diagnosed during hospital admissions 1987-1997, but prior to sexual offending, were retrieved for all adult male SOs released from Swedish prisons 1993-1997 (N = 1215). Preoffending disorder prevalence and associations between morbidity and criminal reconvictions during a 5-year postdetainment follow-up were explored. Alcohol use disorder was the most frequent diagnosis, followed by drug use disorder, personality disorder, and psychosis. Morbidity requiring admission to hospital was more common in rapists as compared to child molesters. Alcohol use disorder, drug use disorder, personality disorder, and psychosis all increased the risk for sexual recidivism whereas alcohol use disorder and personality disorder predicted violent nonsexual recidivism. Controlling for sociodemographic confounds changed the risk estimates only marginally. Because disorders were identified among only those who had been admitted to psychiatric hospitals as inpatients, underestimation of true prevalence rates was inevitable. However, our findings support psychiatric consultation for improved assessment and management of mental health needs and recidivism risk in SOs.     

Juvenile Sex Offenders: A Case Against the Legal and Clinical Status Quo

The past two decades have seen a movement toward harsher legal sanctions and lengthy, restrictive treatment programs for sex offenders. This has not only been the case for adults, but also for juveniles who commit sex offenses. The increased length and severity of legal and clinical interventions for juvenile sex offenders appear to have resulted from three false assumptions: (1) there is an epidemic of juvenile offending, including juvenile sex offending; (2) juvenile sex offenders have more in common with adult sex offenders than with other juvenile delinquents; and (3) in the absence of sex offender-specific treatment, juvenile sex offenders are at exceptionally high risk of reoffending. The available data do not support any of the above assumptions; however, these assumptions continue to influence the treatment and legal interventions applied to juvenile sex offenders and contributed to the application of adult interventions to juvenile sex offending. In so doing, these legal and clinical interventions fail to consider the unique developmental factors that characterize adolescence, and thus may be ineffective or worse. Fortunately, a paradigm shift that acknowledges these developmental factors appears to be emerging in clinical areas of intervention, although this trend does not appear as prevalent in legal sanctions.     

Childhood Attachment,Childhood Sexual Abuse,and Onset of Masturbation Among Adult Sexual Offenders

Written autobiographies of 48 incarcerated adult male sexual offenders (22 rapists, 13 intrafamilial child molesters, and 13 extrafamilial child molesters) were used to generate retrospective self-report measures of their childhood maternal and paternal attachment, childhood sexual abuse experiences, and onset of masturbation. Contrary to expectation, the offenders as a combined group more often reported secure than they did insecure childhood maternal and paternal attachment. There were no differences between the three offender subgroups with respect to maternal attachment; however the rapists and the intrafamilial child molesters were more likely to report insecure paternal attachment than were the extrafamilial child molesters. There were no differences between these offender subgroups in the frequency with which childhood sexual abuse was reported. However, offenders with insecure paternal attachment were more likely to report having been sexually abused than were those with secure paternal attachment. Sexually abused offenders in turn reported earlier onset of masturbation than did those who were not sexually abused. These results are consistent with contemporary attachment models linking insecure childhood attachment to childhood sexual abuse, and with traditional conditioning models linking childhood sexual abuse, early masturbation, and sexual offending.     

Offender and Victim Characteristics of Registered Female Sexual Offenders in Texas: A Proposed Typology of Female Sexual Offenders

Victim and offender characteristic of all registered adult female sexual offenders in Texas (N = 471) were examined. The most common offenses the females were arrested for were indecency with a child--sexual contact, sexual assault on a child, and aggravated sexual assault on a child. The majority (88%) of the females were Caucasian and the ages ranged from 18 to 77 (M = 32). The results of Hierarchical Loglinear Modeling yielded a complex relationship between offender and victim characteristics; thus, identification of preferred victims is mitigated by more than one variable. Additionally, the employment of cluster analysis yielded 6 types of female sexual offenders. The most common group includes 146 offenders, heterosexual nurturers. They were the least likely to have an arrest for a sexual assault. The victims were males who averaged 12 years of age. The other types of offenders included, noncriminal homosexual offenders, female sexual predators, young adult child exploiters, homosexual criminals, and aggressive homosexual offenders.     

Cognitive/Behavioral Treatment for Sexual Offenders: An Examination of Recidivism

Recent research in the treatment of sexual offenders suggests that comprehensive cognitive/behavioral approaches may yield lower recidivism. This study reviewed such a program, existing in Jackson County, Oregon, since 1982. Offenders were mandated into this community-based program upon conviction of a felony or misdemeanor sexual offense, and averaged 2–3 years of participation. A group of offenders who participated in the Jackson County program between 1985 and 1995 was identified through archival data from the Oregon Department of Corrections. The data revealed success or nonsuccess in treatment, and any new convictions for sexual or nonsexual offenses. A control group of nonsexual offenders in Jackson County, and a group of sexual offenders in Linn County who did not have access to any treatment program were also studied. As hypothesized, those Jackson County offenders who successfully completed treatment had lower recidivism rates than those who were unsuccessful in the program. The observed effect of the program was particularly strong for offenders who remained in treatment for 1 year or more. When review was restricted to those participants, the reoffense rate for Jackson County offenders was reduced by over 40% when compared with Linn County offenders.
