Stigma-related stress may contribute to increased risk in individuals who are sexually attracted to children. Further, certain subgroups of people attracted to children may be more stigmatized than others; this has important implications for prevention programs. We conducted a vignette study to examine whether public stigma toward people attracted to children differed based on the person's gender (man/woman), the gender of the child to whom the person is attracted (boy/girl), and preferentiality (non-preferentially/preferentially attracted to children).

We conducted three studies to examine the factor structure and measurement invariance of the Paraphilia Scale, a measure of paraphilic interests used in multiple studies. In the first study, we conducted a confirmatory factor analysis (CFA) testing different a priori models with a community sample of 1,040 adults previously reported by Seto et al. (2021), and found support for a hierarchical four-factor model: An involving coercion or physical pain (biastophilia, sexual sadism, masochism), (pedophilia, hebephilia), (voyeurism, exhibitionism, and frotteurism), and (object fetishism, transvestic fetishism, urophilia-coprophilia).

Sexual arousal in male and female victims during nonconsensual sex is an understudied phenomenon with many potential psychological, clinical, and legal implications for survivors. The aim of this scoping review was to assess the literature to determine whether we could estimate the frequency and circumstances of physiological sexual arousal (e.g.

Low interest in sexual activity and impaired sexual response are among women's most frequent sexual concerns. Mindfulness-based treatments improve low sexual desire and arousal and associated distress. One theorized mechanism of change is the cultivation of increased mind-body awareness via greater concordance between psychological and physiological components of sexual response.

Despite a multitude of theoretical views, it is still unclear how individuals develop and sustain paraphilic interests (e.g., sexual attraction to children, interest in non-consensual violence).

Sexual Interest/Arousal Disorder (SIAD) is a common sexual dysfunction in women. Both mindfulness-based cognitive therapy (MBCT) plus psychoeducation and sex therapy, education, and support (STEP; which contains the same educational information as in the MBCT arm but also integrates supportive-expressive therapy), are effective. We tested mediators and moderators of improvements.

Phallometric assessment is used to assess men's sexual interest in children and to assist in risk assessment and treatment planning. A common response pattern, especially when the assessment is conducted in a forensic context, is an indiscriminate pattern of penile responses: No sexual stimulus seems to produce a substantially higher response than another. This indiscriminate response profile could be the result of (1) (in particular, reducing the responses to child stimuli); (2) floor or ceiling effects caused by low or high , or (3) (the individual is similarly sexually interested in both children and adults).

Some research suggests that video-recorded police incidents may be subject to a camera perspective bias. This study examined whether the camera angle of a recorded police use of force encounter influenced interpretation of the video. Participants (n = 330) viewed a video-recorded simulated use of force scenario in one of four camera angle conditions (body worn camera, bystander camera, security camera, all three camera angles), and then rated the conduct of the police officer and the subject.

There is a general gender difference in paraphilic interests, such that men report more interest (and greater engagement) in a variety of paraphilic behaviors. Using a nonclinical sample, Dawson et al. (Sexual Abuse, 28(1):20-45, 2016, https://doi.

Psychopathy has historically been conceptualized as a mental disorder, but there is growing evidence that it may instead be an alternative, adaptive life history strategy designed by natural selection. Although the etiology of mental disorders is not fully understood, one likely contributor is perturbations affecting neurodevelopment. Nonright-handedness is a sign of such perturbations, and therefore can be used to test these competing models.

Sexual interest/arousal disorder (SIAD) is the most prevalent sexual dysfunction in women. Our goal was to compare (a) group mindfulness-based cognitive therapy (MBCT) plus sex education with (b) group supportive sex education and therapy (STEP) for women with SIAD. Eight-session treatments were delivered weekly and participants completed the measures of sexual desire and arousal, sexual distress, relationship satisfaction, rumination, and global impressions of change, at baseline, immediately posttreatment, and at 6- and 12-month posttreatment.

Forty years ago, researchers documented changes in vascular and muscular activity within the anal canal of women and men who engaged in sexual self-stimulation. Vascular changes were assessed using a photoplethysmograph that aimed to detect changes in pelvic vasocongestion. An important advantage of detecting sexual response within the anal canal is that the device, its anatomical placement, and the data output are identical for women and men, therefore facilitating gender comparisons of response patterns.

Introduction: The vaginal photoplethysmograph (VPP) is a reusable intravaginal device often employed in sexual psychophysiology studies to assess changes in vaginal blood flow, an indicator of sexual arousal.

Aim: To test whether placing a disposable cover on the VPP probe impacts the acquired data. A condom cover would reduce risk of disease transmission and likely increase participant comfort but may negatively impact the VPP signal.

Research conducted in our laboratory and in other laboratories has revealed that (1) women's genital responses to visual and auditory stimuli are strongly affected by the presence of sexual cues, but that (2) specific sexual cues (e.g., gender of actors, the presence of sexual violence) often have little impact on the magnitude of the responses-that is, similar genital responses are observed to very different sexual stimuli.

Purpose Of Review: We examine the state of scientific research on the assessment of paraphilic interests among women who have committed sexual offences.

Recent Findings: Research on the assessment of sexual interests in women using genital measures shows little evidence, overall, that women's genital responses are indicative of sexual interests. Some non-genital measures of sexual interest may be a valid indicator of age interests.

Introduction: The Revised Screening Scale for Pedophilic Interests (SSPI-2) was developed as a screening measure for pedophilia (sexual interest in prepubescent children), but the SSPI-2 items reflect offending against both prepubescent and pubescent children, roughly corresponding to victims under age 15.

Aim: We examined whether the SSPI-2 is better interpreted as a measure of pedohebephilia (sexual interest in both prepubescent and pubescent children) by reanalyzing the original SSPI-2 data and reporting its new psychometric properties.

Methods: The sample was comprised of 1,900 men whose clinical assessment data were entered into an archival database.

Introduction: Pelvic floor surface electromyography (sEMG) is often used in the assessment and treatment of individuals with pelvic floor abnormalities to measure muscle tone and neural control of the pelvic floor muscles (PFM); however, little is known about the role of the PFM in sexual arousal.

Aim: The aim of this pilot study was to examine whether changes in deep and superficial PFM activity-assessed with sEMG-can be observed during the presentation of sexual stimuli.

Methods: Deep PFM sEMG activity was assessed with a vaginal probe.

We examined the latent structure and taxonicity of hypersexuality in large university and community samples of male and female respondents. Participants completed the Hypersexual Behavior Inventory (HBI) and Sexual Compulsivity Scale (SCS), each as part of larger anonymous online surveys of sexual behavior. Exploratory factor analyses (EFA) were performed in part to prepare the data for taxometric analysis and also to identify the putative dimensions underpinning each measure.

Viewing time tasks using still pictures to assess age and gender sexual interests have been well validated and are commonly used. The use of film clips in a viewing time task would open up interesting possibilities for the study of sexual interest toward sexual targets or activities that are not easily captured in still pictures. We examined the validity of a viewing time task using film clips to assess sexual interest toward male and female targets, in a sample of 52 young adults.

Although it is clear that men with a history of sexual assaults against women produce higher relative genital responses to rape vignettes in the laboratory than do men without such a history, it remains unclear what aspects of the vignettes are eliciting these responses, and whether the genital responses are affected by situational factors. The antisocial tendencies hypothesis states that many men are inhibited by cues of violence, suffering, and coercion in rape vignettes, but other men, particularly antisocial and sexually aggressive men, are not so inhibited. In this study, we investigated whether the hypothesized inhibition to rape vignettes among nonoffenders could be affected by manipulation of mood and directed attention.
