The puzzle of intrafamilial child sexual abuse: a meta-analysis comparing intrafamilial and extrafamilial offenders with child victims

Intrafamilial child sexual abuse is a serious social and health problem, yet explanations of sexual offending against children that emphasize antisocial tendencies and atypical sexual interests do not adequately explain intrafamilial offending. In this meta-analysis, we tested other explanations of intrafamilial child sexual abuse by examining 78 independent samples that compared a total of 6605 intrafamilial offenders to a total of 10,573 extrafamilial offenders, in studies disseminated between 1978 and 2013 (Mdn=2000). Intrafamilial offenders were significantly lower on variables reflecting antisocial tendencies (e.g., criminal history, juvenile delinquency, impulsivity, substance use, and psychopathy) and atypical sexual interests (e.g., pedophilia, other paraphilias, and excessive sexual preoccupation). Contrary to other explanations that have been proposed, intrafamilial offenders scored lower on offense-supportive attitudes and beliefs, emotional congruence with children, and interpersonal deficits; intrafamilial offenders also did not differ from extrafamilial offenders on most indicators of psychopathology. Intrafamilial offenders were, however, more likely to have experienced sexual abuse, family abuse or neglect, and poor parent-child attachments. There were too few studies to examine family dynamics - spousal relationship quality, parent-child victim relationship, and family functioning more generally - even though these factors have been frequently mentioned in the clinical and theoretical literatures. Implications for theories of intrafamilial sexual offending, treatment, and future directions for research are discussed.

Non-offending Pedophiles

Non-offending pedophiles are a unique population of individuals who experience sexual interest in children, but despite common misperceptions, have neither had sexual contact with a child nor have accessed illegal child sexual exploitation material. An emerging body of research has examined the prevalence of pedophilic interests, characteristics of non-offending pedophiles, correlates of pedophilic interests, and stigma associated with pedophilia. Treatment programs are beginning to produce findings regarding the effectiveness of treatment in supporting non-offending pedophiles to remain offence-free. The current review spans these areas of research and discusses potential treatment options for working with non-offending pedophiles based on that research base.

Emotional congruence with children and sexual offending against children: a meta-analytic review.

OBJECTIVE Emotional congruence with children is an exaggerated affective and cognitive affiliation with children that is posited to be involved in the initiation and maintenance of sexual offending against children. The current meta-analysis examined the relationship between emotional congruence with children and sexual offending against children, sexual recidivism, and change following sexual offender treatment. METHOD A systematic literature review of online academic databases, conference proceedings, governmental agency websites, and article, book chapter, and book reference lists was performed. Thirty studies on emotional congruence with children in sexual offenders against children (SOC) were included in a random-effects meta-analysis. RESULTS Extrafamilial SOC-especially those with male victims--evidenced higher emotional congruence with children than most non--SOC comparison groups and intrafamilial SOC. In contrast, intrafamilial SOC evidenced less emotional congruence with children than many of the non-SOC comparison groups. Higher levels of emotional congruence with children were associated with moderately higher rates of sexual recidivism. The association between emotional congruence with children and sexual recidivism was significantly stronger in extrafamilial SOC samples (d = 0.58, 95% CI [0.31, 0.85]) compared with intrafamilial SOC samples (d = -0.15, 95% CI [-0.58, 0.27]). Similarly, emotional congruence with children showed a significant reduction from pre- to posttreatment for extrafamilial SOC (d = 0.41, 95% CI [0.33, 0.85]), but not for intrafamilial SOC (d = 0.06, 95% CI [-0.10, 0.22]). CONCLUSIONS Emotional congruence with children is a characteristic of extrafamilial SOC, is moderately predictive of sexual recidivism, and is potentially amenable through treatment efforts.

Sensitivity and Specificity of the Phallometric Test for Hebephilia

INTRODUCTION The phallometric test has been examined most widely in the literature with regard to its ability to detect pedophilia; however, it has become of increasing interest to clinicians and researchers to ascertain to what extent the test accurately detects hebephilia: Whereas pedophilia refers to an adults sexual interest in prepubescent children (age 10 or younger, on average), hebephilia refers to an adults sexual interest in pubescent children (ages 11-14, on average). AIM The aim of this study was to estimate the accuracy of volumetric phallometry in distinguishing pedophilic men and hebephilic men from men who are teleiophilic (primarily sexually interested in adults, age 17 or older). METHODS A retrospective chart review was conducted on the cumulate database of a large phallometric laboratory and clinic to identify a group of 239 men who committed sexual offenses against extrafamilial adults age 17 or older and a group of 996 men who committed sexual offenses against extrafamilial children age 14 or younger, all of whom professed a greater sexual interest in adults over children. MAIN OUTCOME MEASURES The sensitivity and specificity of the phallometric test is calculated for its accuracy in distinguishing sexual preferences for children spanning various age ranges. RESULTS Receiver operator characteristic curves were highly significant for each classification decision: Using its previously established cut-point of +0.25 standard deviation (SD) units, the phallometric test detected hebephilia with a sensitivity and specificity of 70.0% and 90.7%, detected pedophilia with 46.9% and 100%, and detected pedohebephilia with 75.3% and 90.7%. At a new cut-point of +0.0 SD units, the sensitivity and specificity of the test for pedophilia was 71.9% and 95.3%. CONCLUSIONS Volumetric phallometry significantly distinguishes teleiophilic sex offenders from each of pedophilic, hebephilic, and pedohebephilic sex offenders and can serve as a reliable diagnostic test of sexual age preference among men who deny sexual interest in children.

Social anxiety and sexual offending against children: A cumulative meta-analysis

Abstract We examined the extent to which sexual offenders against children (SOC) differ from men who do not offend against children (non-SOC) on social anxiety. In study 1, 30 SOC and 31 non-sex offenders (NSO) were compared on a self-report measure of social anxiety (Social Avoidance and Distress Scale; SADS). SOC and NSO had virtually identical levels of social anxiety. In study 2, we conducted a meta-analysis of existing comparisons of SOC with various non-SOC groups on the SADS. SOC were generally more socially anxious than non-SOC. These findings suggest that the average SOC is more socially anxious than the average male who does not sexually offend against children. It remains unclear, however, whether social anxiety plays a causal role in the initiation of child sexual abuse.

Validity in Phallometric Testing for Sexual Interests in Children: A Meta-Analytic Review:

Valid assessment of pedohebephilic interests (i.e., sexual interest in children) is fundamental to forensic clinical practice. Phallometric testing—which measures changes in penile circumference or volume, while stimuli depicting different ages and sexual activities are presented—is widely used in clinical and research settings to detect such interests. This meta-analysis summarizes studies comparing sexual offenders against children and various types of controls on phallometric tests for pedohebephilic interests (37 samples; N = 6,785) and studies examining the relationship between phallometric test scores and sexual reoffending (16 samples; N = 2,709). The findings suggest that several phallometric testing procedures are valid indicators of pedohebephilic interest. Certain methodological features of phallometric tests were associated with greater validity, such as, slide or audio-plus-slide stimuli and z-score-based indices. In addition, phallometric tests for pedohebephilic, pedophilic, and hebephilic interests predicted sexual reoffending which provides further evidence that phallometric test scores are valid indicators of sexual interest in children. In general, the interpretation of phallometric test scores as indicators of pedohebephilic interests is supported.

Emotional Congruence With Children Is Associated With Sexual Deviancy in Sexual Offenders Against Children

Emotional congruence with children is a psychologically meaningful risk factor for sexual offending against children. The present study examines the correlates of emotional congruence with children in a sample of 424 adult male sexual offenders who started a period of community supervision in Canada, Alaska, and Iowa between 2001 and 2005. Consistent with previous work, we found sexual offenders against children high in emotional congruence with children were more likely to be sexually deviant, have poor sexual self-regulation, experience social loneliness, and have more distorted cognitions about sex with children. Overall, our findings are most consistent with a sexual deviancy model, with some support for a blockage model.

Is childhood sexual victimization associated with cognitive distortions, self-esteem, and emotional congruence with children?

ABSTRACT The current paper examined the association between childhood sexual victimization (CSV) and constructs thought to be relevant for sexual offending in secondary analyses of three samples of adult males who committed sexual offences against children (N = 16, 28, and 20). Compared to participants who reported no CSV, those who reported CSV exhibited slightly to moderately more cognitive distortions and moderately to largely less negative evaluations of sexual offending against children; slightly to moderately higher self-esteem, positive evaluation of people who commit sexual offences, and identification with people who commit sexual offences against children; and much more emotional congruence with children. Our findings suggest that CSV may be associated with variables presumed to play a role in sexual offending against children. However, given the small sample sizes and other limitations of our studies, our evidence does not permit conclusions regarding causal relationships and any novel findings require replication.

Taxometric Analysis of the Latent Structure of Pedophilic Interest

The present study examined the latent structure of pedophilic interest. Using data from phallometric tests for pedophilic interest across four samples of offenders (ns = 805, 632, 531, 261), taxometric analyses were conducted to identify whether pedophilic interest is best characterized as taxonic or dimensional. Across the samples, the majority of analyses supported taxonic latent structure in pedophilic interest. Visual inspection of taxometric curves indicated trichotomous latent structure (i.e., three-ordered classes) may characterize pedophilic interest in these samples. In a second step of taxometric analysis, the results supported trichotomous latent structure, indicating the presence of a complement taxon and two pedophilic taxa. In comparison with the complement taxon, the men in the first pedophilic taxon were non-exclusively pedophilic and had similar rates of sexual recidivism and sexual compulsivity. The men in the second pedophilic taxon were exclusively pedophilic, had more child victims and total victims, sexually re-offended at a higher rate, and were more sexually compulsive. The finding of trichotomous latent structure in pedophilic interest is both consistent and inconsistent with previous taxometric studies and has implications for research, assessment, and treatment of pedophilic interest.
