Sensitivity and specificity of the phallometric test for pedophilia in nonadmitting sex offenders.

The specificity of phallometric testing for pedophilia has been calculated using sex offenders against adult women. Does the offender's actual number of prior sexual contacts with women affect such estimates? To answer this, the authors studied 82 male sex offenders against adult women, 172 offenders against unrelated children, and 70 offenders against their own biological children or stepchildren. Phallometric testing included visual and auditory depictions of prepubescent, pubescent, and adult males and females. The results for offenders against women showed that those who had had sexual contact with the greatest number of women (consenting or nonconsenting) had the lowest probability of being diagnosed as pedophilic. Specificity, calculated for those who had sexual contact with the most women and thus the most evidence of attraction to them, was 96%. Sensitivity, calculated analogously for men with the most offenses against children, was 61%. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Treatment gain for sexual offenders against children predicts reduced recidivism: A comparative validity study.

Objective: To determine whether pro-social treatment change in sexual offenders would predict reductions in recidivism beyond static and dynamic risk factors measured at pretreatment and whether different methods for assessing change based on self-reports and structured clinical rating systems would show convergent validity. Method: We compared 3 methods for assessing treatment change with a sample of adult male sexual offenders against children (n = 218) who completed a prison-based cognitive–behavioral treatment program between 1993 and 2000. The methods were measures of change derived from offender self-reports on a psychometric battery administered both pre- and posttreatment, change across treatment on the Violence Risk Scale: Sexual Offender Version (VRS:SO; Olver, Wong, Nicholaichuk, & Gordon, 2007), and posttreatment ratings on the Standard Goal Attainment Scaling for Sex Offenders (SGAS; Hogue, 1994). Offenders were followed up for an average of 12.24 years after release. Results: All measures of treatment gain were positively correlated, and all significantly predicted reductions in sexual recidivism, with values for the area under the receiver-operating characteristic curve ranging from .66 (SGAS) to .70 (VRS:SO). Survival analyses showed that measures of change based on the psychometric battery significantly predicted recidivism after controlling for both static and dynamic factors measured at pretreatment, while results for the VRS:SO were similar but failed to reach significance. Conclusions: Measures of treatment change based on offender self-reports and structured clinical rating systems show convergent and predictive validity, which suggests that effective treatment that targets dynamic risk factors leads to a reduction in sexual recidivism.

Individual, family, and peer characteristics of adolescent sex offenders and assaultive offenders.

This study examined the individual functioning, family relations, and peer relations of 60 male adolescents who were divided into 4 demographically matched groups (sex offenders, assaultive offenders, nonviolent offenders, and nondelinquent controls). Mothers and adolescents completed self-report inventories and a video-taped interaction task, and teachers completed a rating measure. Results showed that assaultive offenders' family relations were characterized by rigidity and low cohesion and that their peer relations evidenced high levels of aggression. Nevertheless, assaultive offenders and their mothers reported little anxiety or interpersonal discomfort. In contrast, sex offenders and their mothers reported high rates of neurotic symptoms, and the peer relations of sex offenders showed relatively low levels of emotional bonding. Implications for research and emerging theories of delinquency are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Field validity of the STATIC-99 and MnSOST-R among sex offenders evaluated for civil commitment as sexually violent predators.

Despite their widespread use in forensic and correctional practice, surprisingly little research investigates how well actuarial risk assessment instruments (ARAIs) for sexual offenders work within the contexts where they are routinely applied. We examined the predictive validity (M = 4.77 years follow-up) of the two most widely used ARAIs for sexual offenders, the STATIC-99 and Minnesota Sex Offender Sex Offender Screening Tool–Revised (MnSOST-R), as administered in routine practice among 1,928 offenders screened for possible civil commitment as sexually violent predators. Effect sizes for both ARAIs were lower than in most published research and meta-analytic reviews, although the STATIC-99 was a more consistent predictor of recidivism than the MnSOST-R. Recidivism rates for the STATIC-99 were much closer to those expected based on the 2009 norms than the 2003 norms. Offender characteristics (e.g., age at release, prior arrests, release type) were often as or more effective than ARAIs for predicting recidivism. This study, apparently the largest cross-validation study of popular ARAIs for sex offenders, suggests that the predictive validity of these measures in routine practice in the United States may be poorer than often assumed.

Validity of phallometric measures with sex offenders: Comments on the Quinsey, Laws, and Hall debate.

In a recent debate, V. L. Quinsey and D. R. Laws (see record 1991-10127-001) and G. C. Hall (see record 1991-10106-001) discussed several major methodological issues in research on the validity of phallometric tests. This article examines specific points of the debate more closely and uncovers questionnable assumptions underlying some of the Quinsey and Laws criticisms. The implications of unresolved problems for the clinical use of phallometric measures are stressed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Frequency of MMPI two-point code types among sex offenders.

Two-point Minnesota Multiphasic Personality Inventory (MMPI) codes were calculated for 403 convicted sex offenders, yielding 43 code types. The relative frequencies of codes were compared among rapists, child molesters, incest offenders, first offenders, and recidivists. Code frequencies were also compared with frequencies in previously reported studies of psychiatric patients and criminals. Sex offenders showed more 4–5 and 4–8 profiles than other prisoner groups. Rapists showed more profiles that are usually associated with assaultiveness. There were significant differences in code frequencies between incestuous biological fathers and stepfathers and between first offenders and recidivists. The heterogeneity of MMPI profiles precludes stereotypic generalizations about sex-offender characteristics. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Assessment of psychopathy in a population of incarcerated adolescent offenders.

The reliability, validity, and factor structure of a modified version of the Psychopathy Checklist—Revised (PCL—R) for adolescents was investigated, completed using file information only, in a sample of incarcerated Black and White male adolescents. Interrater reliability and internal consistency were high, and confirmatory factor analyses and coefficients of congruence showed that the factor structure in this sample resembled the 2-factor solution found in adults. No significant racial differences were found for reliability or mean PCL—R scores. In addition, relationships between PCL—R scores and psychometric measures and behavioral indicators of maladjustment were similar to those previously found in adult populations. The construct of psychopathy, as defined by the PCL—R modified for use with adolescents, appears applicable to both Black and White adolescent male offenders. The study gives evidence for the structural and substantive validity of the modified PCL—R in this population. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The role of psychologists in state legislation governing sex offenders.

Reports that 27 states have legislation controlling the disposition of accused or adjudicated sex offenders. All allow for or mandate the evaluation, examination, and treatment of the sex offender by psychologists and/or psychiatrists. Although the states vary in their recognition and use of psychologists compared to psychiatrists, it is concluded that psychologists are discriminated against under these laws.

Exploring differences in youth and parent reports of antisociality among adolescent sexual and nonsexual offenders.

This study examined the extent of, and explored several possible explanations for, the discrepancies found between adolescent and parent reports of conduct problems in adolescent sexual and nonsexual offenders. We found that adolescent sexual offenders scored lower on measures of conduct problems than did nonsexual offenders, whether on the basis of adolescent or parent report, though the difference was much larger for parent reports. Examining this discrepancy more closely, we found that parents of sexual offenders reported less antisocial behavior than did their sons, whereas parents of nonsexual offenders reported more antisocial behavior than did their sons. The same pattern of results was obtained for reports on impulsivity, but much less so with respect to antisocial personality traits such as narcissism and callousness. Measures of family functioning were generally not related to these parent–adolescent discrepancies in reports of conduct problems, but these discrepancies were positively correlated with parental reports of stress. The implications of these findings for the interpretation of research on adolescent sexual offenders and comparisons of sexual and nonsexual offenders are discussed.

Substance use and symptomatology among adolescent children of alcoholics.

Assessed the magnitude and specificity of parental alcoholism as a risk factor for internalizing symptomatology, externalizing symptomatology, and alcohol and drug use in adolescence. Parents' and children's reports of symptomatology and children's reports of alcohol and drug use were evaluated in a community sample of 454 adolescents. The results showed that parental alcoholism was a moderate to strong risk factor, with stronger risk associated with recent (rather than remitted) parental alcoholism. Multivariate analyses showed that the specificity of risk varied with the outcome measure. In predicting externalizing symptomatology, the risk associated with parental alcoholism was mediated by co-occurring parental psychopathology and environmental stress. However, in predicting alcohol use, the father's alcoholism was a specific risk factor above and beyond the more generalized effects of stress and family disruption.

The treatment of sex offenders: Risk management and good lives.

How would a good lives model of sex offender treatment differ from a risk-need model? In the good lives model, risk factors are viewed as obstacles that erode individuals' capacities to live more fulfilling lives. The therapeutic focus is thus on implementing offenders' good lives plans rather than simply managing risk. To develop our argument, we first outline the risk-need approach and briefly comment on its core assumptions. We then present the good lives model and discuss the clinical utility of an integrated approach by way of a case example. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The validity of the desired effects of drinking scale with a late adolescent sample.

This study evaluated the validity of the Desired Effects of Drinking Scale (DEoDS) with a late adolescent sample. This brief measure (37 items) was designed to assess reasons for drinking across 9 domains. Across a culturally diverse sample of late adolescents (ages 18-20 years), this measure evidenced high internal consistency, particularly when all items were summed in 1 full-scale score. Contrary to the factors found with adults, 8 factors emerged with this sample. No differences were found by culture, providing initial evidence for the cross-cultural validity of this measure. In addition, gender differences emerged for only 1 factor. Overall, the results provide empirical support for the use of this measure to assess late adolescents' and emerging adults' reasons for drinking.

Statistical definitions of test validity for minority groups.

Considers the problem of deciding when a selection test is invalid for members of a minority group. There is both a strong empirical and theoretical basis for rejecting the choice of zero correlation between test and criterion as an appropriate null hypothesis. The choice typically requires that the population value of the correlation be higher in the minority group than in the majority group. The direct comparison of correlations in minority and majority samples is recommended. Only when the minority correlation is significantly lower and the confidence limits around that correlation include no useful levels of the relationship, should the correlation be considered essentially zero.

Sexual abuse histories of adolescent male sex offenders: Differences on the basis of the age and gender of their victims.

Childhood sexual abuse has often been implicated in the etiology of adolescent sex offending behavior. Victimization rates in the literature vary according to whether data are collected prior (22%) or subsequent (52%) to treatment. Previous research suggests that the incidence of sexual abuse varies as a function of victim age and gender. Sexual abuse histories were collected from 87 adolescent male sex offenders following an average of 13 months of clinical interactions. Offenders were categorized according to the age and gender of their victims; groups were comparable in age and socioeconomic status. It was found that 75% of adolescent offenders who ever assaulted 1 male child reported sexual abuse in comparison to only 25% of those who assaulted female children, peers, or adults. Results suggest that sexual victimization may be an important explanatory variable for adolescent sexual assaults against male children.

Reconsidering vocational interests for personnel selection: The validity of an interest-based selection test in relation to job knowledge, job performance, and continuance intentions.

Although vocational interests have a long history in vocational psychology, they have received extremely limited attention within the recent personnel selection literature. We reconsider some widely held beliefs concerning the (low) validity of interests for predicting criteria important to selection researchers, and we review theory and empirical evidence that challenge such beliefs. We then describe the development and validation of an interests-based selection measure. Results of a large validation study (N = 418) reveal that interests predicted a diverse set of criteria—including measures of job knowledge, job performance, and continuance intentions—with corrected, cross-validated Rs that ranged from .25 to .46 across the criteria (mean R = .31). Interests also provided incremental validity beyond measures of general cognitive aptitude and facets of the Big Five personality dimensions in relation to each criterion. Furthermore, with a couple exceptions, the interest scales were associated with small to medium subgroup differences, which in most cases favored women and racial minorities. Taken as a whole, these results appear to call into question the prevailing thought that vocational interests have limited usefulness for selection.

Substance use escalation and substance use restraint among adolescent children of alcoholics.

Assessed the escalations in substance use over 3 yrs among 246 adolescent children of alcoholics (COAs) and 208 controls (aged 10.5–15.5 yrs). Older COAs showed the steepest escalations in drug use. Younger COAs whose fathers had continuing alcohol-related consequences showed the greatest escalations in alcohol use. Ss' beliefs about drinking restraint were related to their alcohol and drug use. Those whose alcoholic fathers had no continuing alcohol-related consequences showed the strongest relations between substance use and self-control reasons for limiting drinking, perceived risk for future drug problems, and seeing the negative effects of alcohol on someone else. These adolescents may be deterred from substance use escalations because of particular parental characteristics (e.g., mild forms of paternal alcoholism) or because of their beliefs about substance use.

The validation of expressed interests as compared with inventoried interests: a fourteen-year follow-up.

Of 63 sophomores in 1939-40, who took the Strong VIB and a social history interview, occupational choice follow-up data were available in 1953 for 60 Ss. "Apparently the Strong… is most applicable to men reared in the middle class success culture. The Strong seems less applicable for those upper-middle and upper class groups who possess an alternative culture. Among this group, expressed interests are more accurate predictors than the test scores. The inventory predicts Ambitious Careers (feeling… that higher occupational goals can be attained) while the expressed interests predict Responsive Careers (feeling of acceptance with job progression which parents or relatives expect worker to follow)."
