Theories on the Etiology of Deviant Sexual Interests: A Systematic Review.

Not much is known about the etiology, or development, of deviant sexual interests. The aim of this systematic review was to provide a broad overview of current theories on the etiology of sexual deviance. We conducted a systematic search of the databases PubMed and APA PsycInfo (EBSCO). Studies were included when they discussed a theory regarding the etiology or development of sexual deviance. Included studies were assessed on quality criteria for good theories. Common etiological themes were extracted using thematic analysis. We included 47 theories explaining sexual deviance in general as well as various specific deviant sexual interests, such as pedophilia and sadism/masochism. Few theories (k = 7) were of acceptable quality as suggested by our systematic assessment of quality criteria for good theories (QUACGOT). These theories indicated that deviant sexual interests may develop as the result of an interplay of various factors: excitation transfer between emotions and sexual arousal, conditioning, problems with "normative" sexuality, and social learning. Neurobiological findings could not be included as no acceptable quality neurobiological theories could be retrieved. The important roles of excitation transfer and conditioning designate that dynamic, changeable processes take part in the etiology of sexual deviance. These same processes could potentially be deployed to diminish unwanted deviant sexual interests.

Factor Analysis With Unusual Sexual Interests: A Replication Study in a Representative Population Sample.

A previous study found a variety of unusual sexual interests to cluster in a five-factor structure, namely submission/masochism, forbidden sexual activities, dominance/sadism, mysophilia, and fetishism (Schippers et al., 2021). The current study was an empirical replication to examine whether these findings generalized to a representative population sample. An online, anonymous sample (N = 256) representative of the Dutch adult male population rated 32 unusual sexual interests on a scale from 1 (very unappealing) to 7 (very appealing). An exploratory factor analysis assessed whether similar factors would emerge as in the original study. A subsequent confirmatory factor analysis served to confirm the factor structure. Four slightly different factors of sexual interest were found: extreme, illegal and mysophilic sexual activities; light BDSM without real pain or suffering; heavy BDSM that may include pain or suffering; and illegal but lower-sentenced and fetishistic sexual activities. The model fit was acceptable. The representative replication sample was more sexually conservative and showed less sexual engagement than the original convenience sample. On a fundamental level, sexual interest in light BDSM activities and extreme, forbidden, and mysophilic activities seem to be relatively separate constructs.

Excitation Transfer Between Sexual Arousal and Other Emotions in a Community Sample.

Excitation transfer, the transfer of arousal from one emotion to another, might be a mechanism in the development of unusual sexual interests. In this pilot study, we investigated whether we could induce excitation transfer between various emotions and sexual arousal in a laboratory setting with 30 male volunteers. We induced low-level sexual arousal in four different emotional states (aggression/dominance, endearment, fear, disgust) and a neutral state. Sexual arousal was measured using penile plethysmography and self-report. Although there was no mean group effect, possibly due to large interindividual variations, 60% of the subjects showed more sexual arousal in response to sexual stimulation in at least one of the emotional states than in the neutral state. Excitation transfer was most prominent with aggression/dominance and least prominent with disgust. Genital excitation transfer was strongly related to lower penile reactivity and to higher self-reported erotophilia. This pilot study paves the way for further research into excitation transfer as a mechanism to increase the salience of stimuli that otherwise would not have been sexual in nature.

A Meta-Analysis of the Effectiveness of EMDR and TF-CBT in Reducing Trauma Symptoms and Externalizing Behavior Problems in Adolescents.

This multi-level meta-analysis tested if evidence-based trauma treatment was effective in reducing trauma symptoms and externalizing behavior problems in adolescents. Based on eight independent samples and 75 effect sizes, results indicated that Trauma Focused-Cognitive Behavioral Therapy (TF-CBT) and Eye Movement Desensitization Reprocessing (EMDR) had a large and significant overall effect (d = 0.909) on reducing trauma symptoms and externalizing behavior problems. Trauma treatment significantly decreased trauma symptoms (large effect) and externalizing behavior problems (medium effect). Age and type of control group moderated treatment effects. Treatment was more effective in older adolescents. Trauma treatment for adolescents with externalizing behavior problems had a larger effect compared to no treatment, but not compared to treatment as usual. It seems important to provide a broad treatment offer for adolescents with severe externalizing behavior problems, in which, besides trauma treatment, attention is paid to reducing relevant individual risk factors for behavior problems.

Exploratory Factor Analysis of Unusual Sexual Interests.

BACKGROUND: Unusual sexual interests are largely intercorrelated, yet not much is known about underlying patterns of clusters between various sexual interests. AIM: To identify underlying clusters of unusual sexual interests using exploratory factor analysis. METHODS: We conducted exploratory factor analysis with self-reported interest in a wide variety of unusual sexual acts for an online, international sample (N = 669; 61% female), and for women and men separately. Factor regression weights were correlated to self-reported sex life satisfaction, sexual outlet, and psychiatric symptoms. OUTCOMES: Participants rated the attractiveness of 50 unusual sexual activities, and reported on their sex life satisfaction (Arizona Sexual Experiences Scale), sexual outlet, and symptoms regarding ADHD (Adult ADHD Self-Report Screening Scale for DSM-5), depression, anxiety, and stress (Depression, Anxiety, and Stress Scale). RESULTS: We identified 5 factors of unusual sexual interests that were largely comparable for women and men: submission/masochism, forbidden sexual activities, dominance/sadism, mysophilia (attraction to dirtiness or soiled things), and fetishism. For women, unusual sexual interests related to more psychiatric symptoms and higher sexual outlet, whereas this relation was less explicit for men. CLINICAL IMPLICATIONS: Different factors of unusual sexual interests may serve different underlying functions or motivations, for instance related to sexual, and emotional regulation. A better understanding of the nature of unusual sexual interests is important to be able to influence sexual interests that are unwanted or cause damage to others. STRENGTHS & LIMITATIONS: Strength of this study include its anonymity, the avoidance of sexual orientation effects, and the possibility to indicate only a slight endorsement toward sexual items. Limitations include the sample's generalizability and the truthfulness of online responding. CONCLUSION: Unusual sexual interests could be clustered into 5 factors that were largely comparable for women and men: submission/masochism, forbidden sexual activities, dominance/sadism, mysophilia, and fetishism.

Exploring Hostility Toward Women in High-Risk Rapists: The Relevance of Ambivalence and Relational Experience.

Hostility toward women is an established risk factor for sexual violence and is often found to be present in men prone to sexual transgression. There are also clinical indications that high-risk rapists may have more ambivalent attitudes toward women, including the strong desire to be positively evaluated by women. We investigated attitudes toward women in high-risk male rapists (n = 42), nonsexual male offenders (n = 65), and matched male community controls (n = 42), by means of self-report (hostility toward women, benevolent sexism, hostile sexism) and implicit measures assessing associations (Implicit Association Test [IAT]) with "women are deceitful" and "women are prestige objects," and the approach tendency (Approach-Avoidance Task [AAT]) toward women. Results showed that high-risk rapists had a lesser implicit notion of women as deceitful and more explicit benevolent sexism than the community controls. These differences seemed most prevalent in the subgroup of high-risk rapists without any relationship history. It is hypothesized that unrealistically positive attitudes toward women may lead to rejection and frustration, which may influence sexual offending.

A quasi-experimental pilot study to the effects of Responsive Aggression Regulation Therapy (Re-ART) Outpatient for young adults.

It is important to provide treatment for juvenile and young adult violent offenders, since no or (too) late treatment increases the risk of recidivism and persistent aggressive behavior in adulthood. In this study, we investigated the efficacy of the intervention Responsive Aggression Regulation Therapy (Re-ART) Outpatient, which has been developed for adolescents and young adults between 16 and 24 years old with severe aggression problems. This quasi-experimental (pilot) study compared the effects of Re-ART Outpatient (n = 47) with a control group (n = 29) receiving treatment as usual on measures regarding risk of violent recidivism, impulsivity, emotional/personal functioning, family functioning, motivation, handling anger, self-reported problem behavior, coping skills, and cognitive distortions. Re-ART showed significantly better results than the control group on risk of violent recidivism, impulsivity, emotional/personal functioning, motivation, handling anger, certain coping skills, and certain cognitive distortions. Family functioning and self-reported rule-breaking behavior did not differ significantly between the groups. The results implicate that Re-ART is a promising outpatient intervention for young adults with severe aggressive behavior. The results can be explained by the fact that Re-ART treats both systemically and individually and pays specific attention to stress reduction and the improvement of executive functions.

Responsive Aggression Regulation Therapy (Re-ART) Improves Executive Functioning in Adolescents and Young Adults with Severe Aggression Problems: A Pilot Study.

This pilot study (N = 25) compared the effects of a short, four-month version of Responsive Aggression Regulation Therapy Outpatient (Re-ART Compact) and the entire, ten-month intervention (Re-ART Complete) on specific executive functioning (EF) and the risk of violent recidivism in adolescents and young adults (13-23 years). Re-ART is a cognitive behavioral-based intervention for adolescents and young adults with severe aggression problems. The Re-ART Compact and Re-ART Complete groups were comparable on the EF measures inhibition, flexibility, emotion regulation, self-evaluation, and self-control, but the Re-ART Complete group showed more improved risk of violent recidivism. We conclude that Re-ART Compact can be used as a compact, short intervention for EF, which is a valuable addition to the field of forensic mental health care where many problem behaviors relate to poor EF.

Responsive Aggression Regulation Therapy (Re-ART): An Evaluation Study in a Dutch Juvenile Justice Institution in Terms of Recidivism.

This article describes a quasi-experimental study of the effectiveness of Responsive Aggression Regulation Therapy (Re-ART) in terms of recidivism for 16- to 21-year-old juveniles with aggression problems and high risk of recidivism. In a Dutch juvenile justice institution, an experimental group received Re-ART ( n = 63, Re-ART group) and a waitlist control group received Treatment as Usual ( n = 28, TAU group). Results indicated that Re-ART is significantly more effective than TAU in reducing the juveniles' recidivism risk for violent offending. Compared with the TAU group, the Re-ART group showed significantly less violent crimes after 2 and 3 years, less property crimes after 2 years, and less general recidivism after 2 and 3 years. There was no significant difference between groups in recidivism of property crimes with violence. Ethnicity, mild intellectual disabilities, substance abuse, and age did not moderate the effects on recidivism outcome, which indicates that Re-ART was equally effective for various groups.

A statistical comparison of EEG time- and time-frequency domain representations of error processing.

Successful behavior relies on error detection and subsequent remedial adjustment of behavior. Researchers have identified two electrophysiological signatures of error processing: the time-domain error-related negativity (ERN), and the time-frequency domain increased power in the delta/theta frequency bands (~2-8 Hz). The relationship between these two signatures is not entirely clear: on the one hand they occur after the same type of event and with similar latency, but on the other hand, the time-domain ERP component contains only phase-locked activity whereas the time-frequency response additionally contains non-phase-locked dynamics. Here we examined the ERN and error-related delta/theta activity in relation to each other, focusing on within-subject analyses that utilize single-trial data. Using logistic regression, we constructed three statistical models in which the accuracy of each trial was predicted from the ERN, delta/theta power, or both. We found that both the ERN and delta/theta power worked roughly equally well as predictors of single-trial accuracy (~70% accurate prediction). Furthermore, a model including both measures provided a stronger overall prediction compared to either model alone. Based on these findings two conclusions are drawn: first, the phase-locked part of the EEG signal appears to be roughly as predictive of single-trial response accuracy as the non-phase-locked part; second, the single-trial ERP and delta/theta power contain both overlapping and independent information.
