The main objectives of this study were to test a theory-based mediation model in which the relation between childhood sexual abuse (CSA) and dyadic adjustment is mediated through adult sexual avoidance and sexual compulsivity and to examine the gender-invariance of this model. A sample of 686 adults currently involved in a close relationship completed online self-report computerized questionnaires. Prevalence of CSA was 20% in women and 19% in men. In line with our hypotheses, path analyses and structural equation analyses showed that, for both women and men, CSA was associated with more sexual avoidance and sexual compulsivity, which, in turn, predicted lower couple adjustment. Overall, these findings suggest that both avoidant and compulsive sexuality are relevant intervention targets with couples in which one or both partners are CSA survivors.

Using pornography through the Internet is now a common activity even if associated sexual outcomes, including sexual satisfaction, are highly variable. The present study tested a two-step sequential mediation model whereby cyberpornography time use is related to sexual satisfaction through the association with, in a first step, perceived addiction to cyberpornography (i.e., perceived compulsivity, effort to access, and distress toward pornography) and with, in a second step, sexual functioning problems (i.e., sexual dysfunction, compulsion, and avoidance). These differential associations were also examined across gender using model invariance across men and women. A sample of 832 adults from the community completed self-report online questionnaires. Results indicated that 51 percent of women and 90 percent of men reported viewing pornography through the Internet. Path analyses showed indirect complex associations in which cyberpornography time use is associated with sexual dissatisfaction through perceived addiction and sexual functioning problems. These patterns of associations held for both men and women.

This study tested a moderation model in which the association between child sexual abuse severity and negative sexual outcomes (i.e., sexual avoidance and compulsivity) differed as a function of relationships status (i.e., single, cohabiting, and married individuals). A sample of 1,033 adults completed self-report questionnaires online, and 21.5% reported childhood sexual abuse. Path analyses indicated that child sexual abuse severity was associated with higher sexual compulsivity in single individuals, both higher sexual avoidance and compulsivity in cohabiting individuals, and higher sexual avoidance in married individuals. The moderation model was invariant across men and women. These results suggest that the time course of negative sexual outcomes associated with child sexual abuse may follow distinct patterns of expression according to relationship status.

INTRODUCTION Although findings concerning sexual outcomes associated with cyberpornography use are mixed, viewing explicit sexual content online is becoming a common activity for an increasing number of individuals. AIM To investigate heterogeneity in cyberpornography-related sexual outcomes by examining a theoretically and clinically based model suggesting that individuals who spend time viewing online pornography form three distinct profiles (recreational, at-risk, and compulsive) and to examine whether these profiles were associated with sexual well-being, sex, and interpersonal context of pornography use. METHODS The present cluster-analytic study was conducted using a convenience sample of 830 adults who completed online self-reported measurements of cyberpornography use and sexual well-being, which included sexual satisfaction, compulsivity, avoidance, and dysfunction. MAIN OUTCOMES MEASURES Dimensions of cyberpornography use were assessed using the Cyber Pornography Use Inventory. Sexual well-being measurements included the Global Measure of Sexual Satisfaction, the Sexual Compulsivity Scale, the Sexual Avoidance Subscale, and the Arizona Sexual Experiences Scale. RESULTS Cluster analyses indicated three distinct profiles: recreational (75.5%), highly distressed non-compulsive (12.7%), and compulsive (11.8%). Recreational users reported higher sexual satisfaction and lower sexual compulsivity, avoidance, and dysfunction, whereas users with a compulsive profile presented lower sexual satisfaction and dysfunction and higher sexual compulsivity and avoidance. Highly distressed less active users were sexually less satisfied and reported less sexual compulsivity and more sexual dysfunction and avoidance. A larger proportion of women and of dyadic users was found among recreational users, whereas solitary users were more likely to be in the highly distressed less active profile and men were more likely to be in the compulsive profile. CONCLUSION This pattern of results confirms the existence of recreational and compulsive profiles but also demonstrates the existence of an important subgroup of not particularly active, yet highly distressed consumers. Cyberpornography users represent a heterogeneous population, in which each subgroup is associated with specific sexual outcomes.

Intimate Partner Violence in Male Survivors of Child Maltreatment: A Meta-Analysis

Intimate partner violence (IPV) is a major public health concern. Yet, despite an increasingly extensive literature on interpersonal violence, research on male victims of IPV remains sparse and the associations between different forms of child maltreatment (CM) and IPV victimization and perpetration in men remains unclear. The present meta-analysis evaluated five different forms of CM (sexual, physical, and psychological abuses, neglect, and witnessing IPV) as they predicted sexual, psychological, and physical IPV perpetration and victimization in men. Overall, most available studies examined men as perpetrators of IPV, whereas studies of victimization in men were relatively scarce. Results reveal an overall significant association (r = .19) between CM and IPV. The magnitude of this effect did not vary as a function of type (perpetration vs. victimization) or form (sexual, psychological, or physical) of IPV. Although all forms of CM were related to IPV, with effect sizes ranging from .05 (neglect and IPV victimization) to .26 (psychological abuse and IPV victimization), these associations varied in magnitude according to the type of CM. Findings suggest the importance of expanding research on CM and IPV to include a range of different kinds of abuse and neglect and to raise concerns about the experience of men as both victims and perpetrators of IPV.

We tested a mediation model in which the relationship between child sexual abuse (CSA) severity and extradyadic sexual involvement (ESI) is explained through sexual compulsivity. Participants were 669 adults currently involved in an intimate relationship who completed self-report questionnaires. Prevalence of ESI was 32% in women and 57% in men survivors, more than twice the rates among participants with no CSA history. Sexual compulsivity was significantly higher in participants with multiple extradyadic partners as compared to participants reporting only one extradyadic relationship, who nevertheless scored higher than participants reporting no extradyadic partner. The hypothesized structural equation model (SEM) was invariant across men and women and indicated CSA severity was positively and significantly associated with sexual compulsivity, which, in turn, predicted ESI. However, there was also a direct association between CSA and ESI. High CSA severity, directly and through high sexual compulsivity, led to the highest probability of ESI.

Among individuals defined as having been sexually abused based on legal criteria, some will self-report having been abused and some will not. Yet, the empirical correlates of self-definition status are not well studied. Different definitions of abuse may lead to varying prevalence rates and contradictory findings regarding psychological outcomes. The present study examined whether, among legally defined sexual abuse survivors, identifying oneself as having experienced childhood sexual abuse (CSA) was associated with more severe abuse, negative emotional reactions toward the abuse, and current sexual reactions. A convenience sample of 1,021 French-speaking Canadians completed self-report questionnaires online. The prevalence of legally defined CSA was 21.3% in women and 19.6% in men, as compared to 7.1% in women and 3.8% in men for self-defined CSA. Among legally defined sexual abuse survivors, those who identified themselves as CSA survivors had been abused more frequently, were more likely to report a male aggressor, and more often described abuse by a parental figure than those who did not self-identify as abused. Further, self-defined CSA was associated with more negative postabuse reactions and sexual avoidance, whereas those not identifying as sexually abused were more likely to report sexual compulsion.

Response to Editorial Comment: “Profiles of Cyberpornography Use and Sexual Well-Being in Adults”

We thank the author of the editorial comment for the thoughtful remarks on our study. Research on the effects of pornography is still in its infancy. Despite strong social pressure for rapid closure, we should be cautious before concluding that pornography use is universally harmful or beneficial. Our contribution shows that subgroups of pornography users report differential sexual outcomes. Most of our sample was composed of recreational users reporting positive sexual outcomes, including higher sexual satisfaction. High-frequency compulsive use was restricted to 12% of our sample, and another 13% reported low use but significant distress and negative sexual outcomes that cannot be understood within an addiction model.

When Pornography Use Feels Out of Control: The Moderation Effect of Relationship and Sexual Satisfaction

Marie-Ève Daspe; Marie-Pier Vaillancourt-Morel; Yvan Lussier; Stéphane Sabourin; Anik Ferron

ABSTRACT There is an understudied, meaningful distinction between high frequency of pornography use and the subjective feeling that this behavior is out of control. We examined whether the quality of a couples relationship and sex life can strengthen or weaken the association between frequency of Internet pornography use and perceived lack of control over this behavior. In a sample of 1,036 participants, results showed that frequency of pornography use was more strongly associated with feeling out of control when relationship and sexual satisfaction were lower. Findings suggest that couple dissatisfaction puts the individual at risk of reporting out-of-control pornography use.

Self-Perceived Problematic Pornography Use: Beyond Individual Differences and Religiosity

Marie-Pier Vaillancourt-Morel; Sophie Bergeron

Even if pornography use is not inherently addictive, with most users reporting no negative consequences, distress, or functional impairment (Hald & Malamuth, 2008; Vaillancourt-Morel et al., 2017a), data-driven theoretical models focusing on when it may become problematic are sorely lacking. In fact, the burgeoning research on Internet pornography use, particularly that examining correlates of problematic use, has been largely atheoretical to date. This has led to the publication of an increasing number of often contradictory findings, which have fueled unsubstantiated claims about what constitutes problematic pornography use and its consequences. In the absence of a coherent, comprehensive conceptual framework to guide scientific inquiry, the search for etiological explanations has been polarized between dualistic views of pornography use as universally harmful or beneficial, delaying progress in a field where clinically relevant, rigorous research is urgently needed (VaillancourtMorel et al., 2017b). Grubbs, Perry, Wilt, and Reid’s (2018a) integrative model—supported by a systematic review and meta-analysis—fills this significant gap in the literature by organizing some of the predictors of self-perceived problematic pornography use into a dual-pathway conceptualization. The moral incongruence model suggests that mechanisms leading to self-perception of problematic pornography use and distress are (1) dysregulation in pornography use due to individual differences and/or (2) moral incongruence due to moral disapproval of pornography. Although their review and meta-analysis only focus on the moral incongruence pathway, their model suggests that self-perceived problematic pornography use is complex, with distinguishable underlying mechanisms (e.g., emotion dysregulation, moral disapproval of pornography) that may all contribute to the clinical manifestations of perceiving one’s use as problematic. We agree that identifying the conditions under which pornography use may be perceived as problematic is important for both understanding multiple etiologies and developing optimal targeted interventions. However, some components of this integrative model warrant additional consideration, particularly in light of future studies. In this comment, we will: (1) address the limitations of what Grubbs et al.’s model is predicting—self-perceived problematic use—followed by how it could be expanded upon by including: (2) other predictors of moral disapproval of pornography and (3) an interpersonal contextual view.
