Non-partner sexual violence against women
Non-partner sexual violence (NPSV) against women is a serious public health concern with substantial implications for mental and sexual health. However, data on its prevalence, patterns—including victim–perpetrator relationship, event context, and nature of acts—and related outcomes remain limited. This study investigates the lifetime prevalence and patterns of NPSV among women in Iran, its psychosexual impacts, and victims’ coping strategies. Th…
Perceived Partner Responsiveness Is Associated With Adolescent Sexual Wellbeing Over 1 Year
INTRODUCTION: Research on adolescent sexuality is primarily cross-sectional and often neglects interpersonal factors that may play a key role in promoting their sexual wellbeing, such as perceived partner responsiveness, that is, feeling understood, cared for, and accepted by a partner. The current study examined prospective associations between perceived partner responsiveness and sexual wellbeing (sexual satisfaction, sexual desire/arousal, org…
Associations Between Childhood Maltreatment, Fluctuations and Discrepancies in Partners’ Sexual Desire and Distress
Childhood maltreatment (CM) is associated with persistent difficulties in adult sexual relationships and functioning. Sexual desire and distress are frequent concerns in clinical settings and studies have shown that CM is linked to lower sexual desire, higher sexual distress, and challenges affecting romantic partners. Most prior studies relied on retrospective reports, overlooking daily fluctuations and discrepancies in sexual desire and distres…
Sexual Assertiveness and Sexual Victimization Across Different Life Stages
Objectives A growing body of research indicate that experiencing sexual victimization may be linked to lower levels of sexual assertiveness, yet significant gaps remain in understanding how this association varies across the life stages in which one is victimized, gender identities, and cultural contexts. Prior studies have primarily focused on cisgender women from Western countries, mainly examined adolescent/adult sexual assault (AASA), and emp…
Between Struggle and Strength
Although several studies have shown that one person’s trauma is associated with romantic relationship difficulties for both partners in adulthood, most have overlooked the particularity of dual-trauma couples, in which both partners have experienced traumatic experiences. This rapid review investigated the dynamics and challenges within dual-trauma couples. A rapid review methodology was employed to consolidate and evaluate existing knowledge in …
A systematic review of technology-mediated conflict management in couples
Digital technologies are now firmly ingrained in our daily lives and have become inevitable tools for interacting with a romantic partner. Beyond helping partners feel connected when apart, technology-mediated communication (TMC) is also widely used to discuss conflictual issues within romantic relationships. Given that managing conflicts efficiently is central to relationship maintenance, couple satisfaction, and intimacy, it is important to und…
Childhood Sexual Abuse and Cognitive, Affective, and Behavioral Responses to Partner Touch
Objective This dyadic study examined how childhood sexual abuse is associated with cognitive, affective, and behavioral responses anticipated in reaction to different types of hypothetical partner touch. Background Trauma theories contend that childhood sexual abuse is associated with long‐term relational challenges, including difficulties with intimacy and physical touch. Touch plays a central role in fostering connection and well‐being in coupl…
Navigating Cyber Intimate Partner Violence and Conflict
Young adult couples frequently use text messages to discuss conflicts within their relationship. While face-to-face conflicts have been shown to elicit more negative anticipation and negative emotions in victims of traditional, offline forms of intimate partner violence (IPV) (e.g., psychological and physical) compared with nonvictims, no study has examined how victims of cyber IPV (C-IPV) experience conflicts, either text-based or face-to-face. …

Introduit en 2013 dans le DSM-5, le Modèle alternatif …
Dyadic empathy following childhood trauma
Targeting hostile attributions among individuals with CCIT might constitute an interesting pathway to enhance their own and their partner's empathy within the relationship and, therefore, foster positive couple dynamics during young adulthood.

Empathic accuracy in couples
Empathic accuracy-the ability to accurately infer one's partner's emotions-has important implications for couples' relational well-being. Although distinct emotions convey various needs and elicit different responses between romantic partners, research on empathic accuracy-its patterns, underlying processes and relational consequences-across a spectrum of discrete emotions directed towards the partner or the relationship remains sparse. This stud…

Multidimensional Perfectionism and Sexual Difficulties Among Adult Couples
The multidimensional model of perfectionism includes three dimensions: Self-oriented perfectionism (SOP), other-oriented perfectionism (OOP), and socially prescribed perfectionism (SPP). Although previous research has identified significant cross-sectional associations between perfectionism and sexual function, these studies predominantly focused on women without examining the links between the different dimensions of perfectionism and various in…

Are pornography use motivations related to behaviors toward the romantic partner? A dyadic daily diary study
Individuals in couple relationships often use pornography. Previous findings are inconsistent regarding how pornography use may affect couples and tend to focus on overall use and broad retrospective indicators of relationship functioning (e.g., relationship satisfaction). No research has considered the motivations behind pornography use and how they relate to daily dynamics between partners. Yet, the approach-avoidance sexual motivation theory s…

Cross-Cultural Validation of the Sexual Desire Inventory (SDI-2) in 42 Countries and 26 Languages
Sexual desire is a complex construct with important implications for sexual functioning and well-being. In this research, we translated the Sexual Desire Inventory (SDI-2), a widely used scale for assessing sexual (desire), into 25 languages from English and used data from the International Sex Survey (ISS) to (a) investigate its psychometric properties (i.e. factorial structure, reliability, validity, and measurement invariance) and (b) explore …
Associations Between Pornography Use Through Different Media and Sexual and Relationship Satisfaction Among Cohabiting Couples
Intimacy Promotes Couples’ Sexual Well-Being on a Daily Basis and Over One Year
Pornography use and romantic relationships
Pornography use is now considered a normative sexual activity, including for partnered individuals. Although there are documented positive and negative effects of pornography use on romantic relationships, studies to date suffer from key limitations, narrowing their clinical relevance. Most rely on vague recall measurement that may inadequately capture actual pornography use, and all are exclusively based on mixed-sex couples. This study used a 3…
Magnitude and Risk Factors for Interpersonal Violence Experienced by Canadian Teenagers in the Sport Context

However, in Canada, little scientific evidence on the prevalence of this issue exists. The objective of this study was to describe the magnitude of interpersonal violence toward young Canadian athletes in the context of sport and to explore associated risk factors. A total of 1,055 athletes, aged between 14 and 17 years, anonym…

Associations Between Pornography Use Frequency, Pornography Use Motivations, and Sexual Wellbeing in Couples
Pornography use is prevalent, even among partnered individuals. Although pornography use motivations represent key predictors of sexual behaviors, prior studies only assessed the associations between pornography use frequency and sexual wellbeing, with mixed results. This cross-sectional dyadic study examined the associations between partners' individual and partnered pornography use frequency, motivations, and sexual wellbeing. Self-report data …
Will you be happy for me? Associations between self-reported, perceived, and observed responses to positive events and sexual well-being in cohabiting couples
Whereas greater levels of intimacy have been shown to promote couples’ sexual well-being, recent theories suggest that satisfying sex is maintained via the capacity to encourage the partner’s individuality, while remaining intimately connected. Responses to capitalization attempts (i.e., the disclosure of a positive personal event) provide an opportunity to strengthen both the couple’s intimacy and each partner’s autonomy. Although responses to c…
Partner Knowledge of Solitary Pornography Use
Pornography use is a common sexual activity engaged in mostly alone, including for partnered individuals. Evidence concerning the benefits and costs of solitary pornography use for romantic relationship quality is mixed and may vary depending on the circumstances of pornography use, including partner knowledge of one's solitary use. Adopting a dyadic daily diary and longitudinal design, we examined the associations between knowledge of a partner'…

Motivations for pornography use may vary across gender identities, sexual orientations, and geographical regions, warranting examination to promote individual and public health. The aims of this study were to validate the Pornography Use Motivations Scale (PUMS) in a diverse, multicultural sample, and develop a short form (PUMS-8) that can assess a wide range of pornography use motivations. Using data from 42 countries (N = 75,117; Mage = 32.07; …
A Dyadic Longitudinal Study of Child Maltreatment and Sexual Well-Being in Adult Couples
This study examined the contribution of child maltreatment (CM) to trajectories of couples' sexual well-being, and whether relationship satisfaction moderates these associations. Using a sample of 269 mixed-sex couples followed over one year, dyadic latent growth curve models showed both actor and partner effects. In terms of actor effects, women's emotional neglect was associated with lower initial levels of sexual satisfaction, and most types o…
Associations Between Contents of Pornography and Sexual Satisfaction and Function Among Young Adults
Pornography offers a wide variety of sexual contents and has documented potential positive (e.g., higher sexual satisfaction) and negative associations (e.g., lower sexual function) with sexuality. The aims of this study were to describe the proportion of use of five different contents of pornography (i.e. group sex, passion and romance, gender-bending, taboo transgression and forbidden sex, power, control, and rough sex pornography), to examine …
Cross-cultural Validation of the Arizona Sexual Experience Scale (Asex) in 42 Countries and 26 Languages
Introduction The Arizona Sexual Experiences Scale (ASEX) is a brief questionnaire that evaluates five major aspects of sexual function: sex drive, arousal, erectile function/vaginal lubrication, ability to reach orgasm, and satisfaction with orgasm. An advantage of the ASEX is its simplicity and brevity (five items), making it suitable for the screening of sexual function problems in healthcare contexts and large-scale studies. The main objective…
Extradyadic Sexual Involvement and Sexual Compulsivity in Male and Female Sexual Abuse Survivors
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 si…
Intimacy Promotes Couples’ Sexual Well-Being on a Daily Basis and Over One Year
Longitudinal associations between childhood maltreatment and sexual motivations in couples
Childhood maltreatment (CM) has been consistently associated with negative sexual outcomes in couples. Yet, its link with sexual motivation, which plays a key role in relational and sexual well-being, remains elusive. Based on self-determination theory, sexual motivations encompass intrinsic motivation, extrinsic motivation (i.e., integrated, identified, introjected, and external), and amotivation. This study examined the dyadic longitudinal asso…
Associations between Conflict Negotiation Strategies, Sexual Comfort, and Sexual Satisfaction in Adolescent Romantic Relationships
Achieving healthy and satisfying sexual relationships is a major developmental task in adolescence, but factors promoting sexual satisfaction among adolescent romantic relationships remain underexplored. Since sexuality is shaped by relational experiences, strategies mobilized to negotiate conflicts in romantic relationships could be related to sexual satisfaction through comfort in negotiating sexual experiences. Sexual comfort refers to the eas…

Adolescents’ Self Perceptions
Adolescence is a crucial period for the development of the sexual self-concept. While existing research shows that adolescents' sexual self-concept varies, few studies have examined its relation with psychosocial competencies such as the general self-concept, interpersonal skills, and self-control capacities. The objective of this study was to examine the association between dimensions of the sexual self-concept (sexual self- and body esteem, sel…

Intimate Partner Violence in Male Survivors of Child Maltreatment
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 witn…
For the love of being liked
Introduction: Some Facebook users have difficulty regulating the amount of time they spend online, and some Facebook features, such as likes, promote habitual use. Theoretically, attachment insecurities could be related to problematic Facebook use, but the findings of past studies were mixed with limited knowledge about potential moderators and mediators of the association between adult attachment and problematic use of Facebook.Aims: The present…

An Attachment Perspective on Partner Responses to Genito-pelvic Pain and Their Associations with Relationship and Sexual Outcomes
Although facilitative and negative partner responses are known to impact couples' adaptation to provoked vestibulodynia (PVD), a chronic genito-pelvic pain condition, it is still unknown what leads individuals to adopt or perceive such adaptative or detrimental behaviors. Attachment influences sexual and relationship adjustment, emotional reactivity and perceived support in romantic relationships, and as such could be associated with partner resp…

Sexual Violence Against Persons With Disabilities
A growing number of large-scale studies suggest that people with disabilities are at greater risk of sexual victimization than nondisabled individuals. However, certain results are inconsistent and whether potential moderators explain this variability in previous findings remain to be considered. This meta-analysis aimed to determine the magnitude of the difference in risk of being sexually victimized based on the presence of a disability. An add…

Social media jealousy and intimate partner violence in young adults’ romantic relationships
Hooked on a feeling
Intimate partners experience more negative emotion in response to sexual versus nonsexual conflicts in their relationship. Negative emotions hinder communication and sexual well-being. In a laboratory-based observational study, we tested the prediction that couples who took longer to downregulate negative emotion during a sexual conflict discussion would report lower sexual well-being. Long-term couples ( N = 150) were video recorded while they d…
