Research on intimate partner violence (IPV) has traditionally examined perpetration and victimization separately, limiting understanding of the relational processes that sustain violence. The present selective review builds on the dyadic model of partner violence by synthesizing meta-analytic evidence concerning risk markers for physical IPV. Eight peer-reviewed meta-analyses published between 2000 and 2024 formed the core synthesis. Studies were included if they reported quantitative effect sizes for variables associated with physical IPV perpetration or victimization. Extracted results were organized into three hierarchical levels: (a) background and dispositional risk markers, (b) relationship context, and (c) situational context. Across the reviewed meta-analyses, the most consistent risk markers of IPV clustered within the relationship-context level, particularly prior partner aggression, emotional abuse, and relationship dissatisfaction. Communication skills and empathy were inversely associated with IPV risk. Few studies examined same-sex couples, IPV victimization among men, or culturally diverse samples, highlighting major gaps in current evidence. This selective review provides an updated synthesis and conceptual organization of IPV risk markers and emphasizes the importance of dyadic frameworks for guiding future theory, prevention, and policy.

The current study examined whether individual differences in attachment orientation, mate-retention tactics (benefit-provisioning and cost-inflicting strategies), and COVID-19-related stressors (impact, uncertainty, and perceived risk) were associated with IPV victimisation across two time points, one month apart, in Brazil and the UK (N = 1416 at Wave 1; N = 353 at Wave 2). Linear mixed-effects models controlled for age, sex, ethnicity, and relationship length. IPV victimisation did not significantly change over time, and COVID-19-related variables were not associated with any form of IPV. Brazilian participants reported higher psychological IPV than UK participants, although no country differences emerged for physical or sexual IPV. Cost-inflicting mate-retention strategies were positively associated with all forms of IPV in both countries, with consistently stronger associations in the UK. Attachment avoidance was positively associated with all forms of IPV in Brazil but was negatively associated with psychological and sexual IPV in the UK. Attachment anxiety and benefit-provisioning strategies were associated with psychological IPV in Brazil only. These findings suggest that associations between attachment, mate-retention strategies, and IPV victimisation may vary across cultural contexts, underscoring the value of culturally sensitive approaches to IPV research and intervention.

Background: Between 33% and 75% of women who experience intimate partner violence (IPV) sustain an IPV-related traumatic brain injury (TBI). Although IPV-related TBI is associated with adverse psychosocial outcomes, its impact on response to healthcare-based IPV interventions remains unclear. Methods: Using data from a randomized clinical trial within the Veterans Health Administration, we examined psychosocial outcomes among 60 woman veterans with past-year IPV experiences participating in two brief IPV interventions: Enhanced Care As Usual (ECAU) and Recovering from IPV through Strengths and Empowerment (RISE). Results: At pretreatment, 21 women (35%) reported a history of probable IPV-related TBI. Multilevel modeling revealed no significant main or interaction effects of TBI history for self-efficacy, empowerment, patient activation, depression, physical health symptoms, or resilience. However, there was a significant interaction of time and probable IPV-related TBI history for valued living, such that women with probable IPV-related TBI history demonstrated greater initial gains followed by slight posttreatment decline; F(2, 76.55) = 2.96, p = 0.049. There was also a significant interaction between probable IPV-related TBI history, treatment condition, and pretreatment anxiety symptoms for anxiety symptoms as an outcome, such that women with probable IPV-related TBI history in the RISE condition, who had more severe anxiety symptoms at pretreatment, reported higher anxiety symptoms on average across the study period than women without probable IPV-related TBI history in RISE; F(1, 48) = 5.04, p = 0.029. Furthermore, there was a significant interaction of probable IPV-related TBI history and pretreatment physical health symptoms for physical health symptoms as an outcome, such that women with probable IPV-related TBI histories maintained higher physical symptoms from pretreatment to the last follow-up assessment; F(1, 134) = 8.99, p = 0.004. Conclusions: No evidence of differential treatment response was detected for women with and without probable IPV-related TBI history. Findings related to valued living and anxiety suggest areas where additional support may improve implementation of brief healthcare-based IPV interventions. Full article

Despite intimate partner violence (IPV) being a global issue, research on societal attitudes focuses on victim-survivor over and above perpetrator characteristics. Across two studies, we investigated whether judgements (measured across victim blame, perceived criminality, and anticipated harm) differed as a function of perpetrator sex (male, female) and whether the perpetrator reported a general (Study 1: n = 183) or specific (physical, mental) disability (Study 2: n = 237). After controlling for variation in personality, beliefs, and demographics, we consistently observed punitive judgements (i.e., less victim blame, and higher perceived criminality and anticipated harm) for vignettes depicting the perpetrator as male and not disabled. Findings are discussed within frameworks that examine the intersection of disability and violence, and how typical depictions of perpetrators of IPV mitigate the recognition of IPV and the minimisation thereof. We call for an international, qualitative exploration into the role of disability in IPV through the experiences of victim-survivors and perpetrators, and further interrogation into how disability in this context impacts victim-blame reduction interventions, support provision, and legal system responses.

Objectives: Antiviral vaccines are usually created by inactivating viruses using physical or chemical methods. Inactivation of poliovirus with β-propiolactone (BPL) has advantages, including the absence of a requirement for long-term incubation with the inactivating agent, which minimizes the risk of negative effects of the potentially dangerous substance on the virus and reduces the duration of the inactivation process. Methods: BPL was applied at 0.2% (w/v) concentration under two conditions: 4 °C for 24 h and 37 °C for 3 h. Inactivation completeness was confirmed on Vero cell culture, while immunogenicity was assessed in guinea pigs via neutralizing antibody test. Conclusions: Two variants of virus inactivation made it possible to obtain inactivated samples that retained their immunogenic properties. BPL-inactivated samples retained sufficient D-antigen levels and elicited neutralizing antibodies comparable to or exceeding those from formaldehyde-inactivated controls. The inactivation method at 37 °C provided faster inactivation, while at 4 °C it provided a smooth decrease in virus titer. These results confirm that β-propiolactone is a viable alternative to formaldehyde for the production of inactivated polio vaccine (IPV), providing rapid inactivation of the virus compared to inactivation with formaldehyde while maintaining immunogenicity, as confirmed by guinea pig control.

Background: Education and employment are widely promoted as pathways to reducing intimate partner violence (IPV) through enhanced economic independence and bargaining power. However, evidence from settings characterised by entrenched gender inequalities suggests that these structural factors may not uniformly translate into protection. This study examines whether education and employment are associated with women’s experiences of IPV in South Africa. Methods: This study utilised nationally representative data from the South Africa Demographic and Health Survey (N = 2354). Education and employment were used as structural proxies for women’s socioeconomic positioning. Survey-adjusted logistic regression models were employed to estimate associations between these factors and lifetime IPV, controlling for key sociodemographic characteristics. Given the cross-sectional design and the use of lifetime IPV alongside contemporaneous measures of education and employment, findings are interpreted as associative rather than causal. Results: Education and employment were not significantly associated with women’s likelihood of experiencing IPV. Women with these characteristics were not less likely to report emotional, physical, or sexual violence compared to those without them. IPV prevalence was higher among women aged 25–34, those with secondary education, and those in lower wealth households. Marital status emerged as a strong correlate, with separated and divorced women facing substantially higher odds of IPV. Discussion: The absence of a significant association suggests that education and employment alone may be insufficient to reduce IPV risk in contexts where gender norms and relational power imbalances remain entrenched. These findings may also reflect the limitations of using structural indicators as proxies for empowerment, as such measures do not capture decision-making power, control over resources, or intra-household dynamics. Conclusions: Interventions to reduce IPV should extend beyond improving women’s access to education and employment to address relational, normative, and structural drivers of violence. Multidimensional approaches that incorporate gender-transformative strategies and strengthen women’s substantive agency are likely to be more effective. Full article

With the development of space-based cloud computing and on-orbit intelligent processing, higher requirements have been imposed on standardized network interconnection for spaceborne platforms. However, constrained by size, power consumption, thermal design, and structural layout, some spaceborne platforms lack physical Ethernet interfaces and therefore cannot directly support standard Internet Protocol version 6 (IPv6) communications. In addition, harsh spaceborne operating conditions, including thermal-vacuum stress and potential radiation-induced disturbances, increase the risk of link anomalies, state inconsistency, and service interruption. To address these issues, this paper proposes a reliability-enhanced IPv6 access and transmission method for spaceborne platforms without physical Ethernet interfaces. On the processor side, a network TAP interface is established to reconstruct the semantics of a standard Layer-2 network device. Combined with a cooperative central processing unit–field-programmable gate array (CPU–FPGA) link-carrying mechanism, the proposed method enables transparent IPv6 access without modifying the native Linux protocol stack. To satisfy both standard spacecraft onboard network services and high-throughput engineering data transmission, a dual-channel architecture is designed, in which the service network channel is separated from the engineering data channel. In addition, a hierarchical reliability-oriented mechanism is constructed, consisting of hardware-level fault-tolerance design, reliable link interaction, status monitoring, and redundancy takeover. Experimental validation is conducted on a CPU-FPGA prototype platform under a thermal-vacuum environment and representative abnormal operating scenarios. The results show that the proposed method can stably support IPv6 address configuration, neighbor discovery, and end-to-end communication. Under zero-packet-loss conditions, the service network channel achieves an average stable throughput of 173.8 Mb/s, while the engineering data channel achieves a stable throughput of approximately 3.4 Gb/s. The system also demonstrates good service continuity during long-duration operation and under typical abnormal scenarios. The proposed method provides a verifiable system-level solution for realizing standardized IPv6 network access and reliability-enhanced data transmission on interface-constrained spaceborne platforms.

Background and Objectives: Intimate partner violence (IPV) is a major public health concern, with nearly one in three women experiencing rape, physical assault, stalking, emotional manipulation, or a combination of these behaviors in their lifetime. As an often neglected cause of injury worldwide, IPV is underreported and not well recognized by healthcare professionals. Employment has been identified as a key factor in women’s successful disentanglement from IPV. The purpose of this qualitative study was to explore the factors that influenced women who had experienced IPV, established a career path, and successfully disentangled from IPV. Materials and Methods: Women who experienced IPV were recruited from a local university. Results: Ten female participants completed open-ended interviews (mean age = 47, SD = 10.25). Five main themes emerged as the most important in disentangling from their abusive situation: tipping point, grit, religion, children, and education/career. The main theme or step in the process that led to disentanglement was the tipping point. Once the tipping point had been reached, participants moved toward disentanglement. Conclusions: Disentanglement from IPV was enhanced for women who reached a tipping point of abuse. Full article

Intimate partner violence (IPV) affects individuals of all genders and can result in adverse physical, psychological, and social outcomes. Experiences of IPV in men remain understudied when compared with those of cisgender women, leading to considerable gaps in understanding of prevalence, experiences, disclosure, and outcomes. The Male Experiences of Intimate Partner Violence Study (ME-IPV Study) was designed to explore: nature of IPV experiences, physical and psychological impacts, barriers to reporting/disclosing, experiences of disclosure, experiences of support, and support needs in a Northern Ireland (NI) context. This mixed-method study utilised data from N = 10 qualitative interview participants (quantitative results reported separately), analysed using an Interpretative Phenomenological Analysis (IPA) framework. Participants described experiencing multiple forms of IPV, with coercive control, psychological and institutional abuse being highly prevalent. Detrimental effects of their experiences included diagnoses of anxiety, depression, and PTSD, physical symptomology, the advent/exacerbation of multiple health conditions, and suicidal ideation. Barriers to care were primarily a lack of dedicated care pathway, concerns over being believed, and stigmatic barriers. Experiences of disclosure were mixed: positive with family/friends and negative with police and institutions of state. Male experiences of IPV in NI are a significant public health issue and it is evident that the impacts of IPV on men’s physical/mental health and wellbeing are profound. Full article

Although the consequences of intimate partner violence (IPV) for female victims have been widely documented, the psychological and academic correlates of perpetration remain underexplored. This study examines whether emotional distress statistically mediates the association between IPV perpetration and academic presenteeism among male university students. A cross-sectional survey was administered to 343 students from the Universidad Mayor de San Andrés in Bolivia. Using validated instruments and Partial Least Squares Structural Equation Modeling, we assessed direct and indirect associations. Findings indicate that 50.1% of students reported perpetrating at least one form of IPV since entering university, with stalking and psychological violence being most common. Perpetrators reported higher levels of emotional distress compared to non-perpetrators and exhibited higher academic presenteeism (reduced academic functioning despite physical attendance). The structural model indicated a significant indirect statistical effect of IPV perpetration on academic presenteeism through emotional distress (β = 0.137, p < 0.001), accounting for 36.2% of the total effect. These findings suggest that universities may consider perpetrator-focused components within broader prevention and support systems, integrating behavioral accountability with screening, referral, and academic support while recognizing that intervention effectiveness was not tested in this study.

Intimate partner violence (IPV) against women is recognized as a public health and human rights issue globally. Nigeria continues to experience a substantial burden of IPV. This study analyzed patterns and multilevel factors associated with violence against women in Nigeria, including emotional, physical, and sexual violence. This study analyzed data from 5458 women aged 15 to 49 years who participated in the 2024 Nigeria Demographic and Health Survey (NDHS). We computed multivariable binary logistic regression and Firth logistic regression (for relatively rare events). Women whose partners consumed alcohol had higher odds of experiencing emotional violence (AOR = 2.97), less severe physical violence (AOR = 3.11), severe physical violence (AOR = 3.22), and sexual violence (AOR = 2.07). Partner controlling behaviors, including restricting contact with family or friends, was also consistently linked to elevated IPV risk. Women living with a partner had higher odds of severe physical and sexual violence. Higher education and greater household wealth were associated with lower IPV outcomes. Our study provides practice-relevant evidence and policy implications, including the need for integrated prevention strategies that address behavioral risk factors, strengthen early screening for controlling behaviors, and promote women’s socioeconomic empowerment.

Globally, intimate partner violence (IPV) is a public health concern and the most prevalent type of violence against women. Social norms that condone violence have been strongly associated with intimate partner violence, making them relevant to women’s wellbeing. The identification of social norms unique to a population is necessary for interventions based on shifting social norms. Thus, the current research is aimed at examining the association between women’s attitudes toward wife-beating (a social norm) and women’s experiences of partner’s controlling behavior, physical violence, and emotional and sexual abuse in Tanzania from national representative data. The cross-sectional data used for the study were from Tanzanian women (n = 3033) aged 15–49 years who have ever been married or in a relationship and responded to the domestic violence questionnaire. Nearly, 60% of women reported that their most recent partner had engaged in controlling behavior, 27.5% had experienced physical violence, while 23% and 9.1% had experienced emotional and sexual violence, respectively. The multivariate analysis revealed that IPV was more common among women who had a positive attitude toward wife-beating. In addition to other behavioral and structural interventions, changing societal norms that support violence against women may be helpful to prevent IPV among Tanzanian women. Full article

Background: Intimate partner violence (IPV) is a pervasive medical concern affecting millions of people worldwide, with the majority being women. IPV is linked to a number of long-term physical and mental health consequences, including brain injuries and associated persistent post-concussion symptoms (PPCS) and post-traumatic stress disorder (PTSD). Despite the high prevalence of these conditions, there is sparse literature assessing accessible and effective therapeutic avenues specific to IPV victim-survivors. Methods: This narrative review had two aims: to identify therapeutic studies addressing PTSD and PPCS in women IPV survivors, and to provide a narrative overview of potential therapeutic categories, including psychotherapy, mindfulness and meditation, exercise, and pharmacotherapy. A comprehensive literature search was conducted using PubMed and Google Scholar. Inclusion criteria required full-text, peer-reviewed articles published in English, conducted in women with a history of IPV, reporting treatment outcomes related to PTSD or PPCS. Where no IPV-specific evidence was identified, findings from closely related populations including military veterans, athletes, and general TBI samples were narratively reviewed to inform potential therapeutic implications. Results: Nineteen studies addressing PTSD in women IPV survivors were identified, predominantly utilizing psychotherapeutic or mindfulness and meditation-based interventions. No intervention studies targeting PPCS specifically in IPV survivors were identified. Consequently, results for PPCS are largely extrapolated from adjacent populations. Although potential therapeutic avenues were narratively identified across psychotherapy, mindfulness and meditation, exercise, and pharmacotherapy, IPV-specific evidence remains limited, and validation for PTSD and PPCS in this population is needed before clinical recommendations can be made. Conclusions: While 19 studies identified promising therapeutic options for IPV-related PTSD, no IPV-specific PPCS interventions were identified, and implications for PPCS management remain largely inferential. Validation and integrated trauma-informed approaches addressing the intersection of PTSD and PPCS are needed for this understudied population. Full article

Domestic violence against men remains significantly under-recognized, despite affecting 20–40% of men worldwide. Societal stigma, gender-normative expectations, and institutional biases often discourage help-seeking behaviors among male victims. This retrospective analysis characterizes domestic violence against adult men by examining victim–perpetrator dynamics, injury patterns, reporting behaviors, and behavioral barriers to help-seeking within an Italian emergency department setting. Overall, 80 adult male domestic violence victims presenting to the Emergency Department of Careggi University Hospital (Florence, Italy) between January 2017 and December 2022 were examined. Data included demographics, injury characteristics, perpetrator relationships, and formal reporting rates. Descriptive statistics and chi-square tests were used to examine associations between victim characteristics and help-seeking behaviors. The majority of victims were Italian men (age range 18–90 years, mean 44.2 ± 15.1); of these, 55% experienced IPV perpetrated by female partners. Physical injuries were predominantly minor (classified as minor according to ED prognosis ≤ 7 days) (78.8%), including abrasions and contusions affecting the head (52.5%), neck (28.8%), and upper limbs (41.3%). Formal reports were filed with judicial authorities in 58.8% of cases, yet only 15% accepted protective interventions. Visible facial injuries (OR = 3.85, 95% CI, p = 0.004) and female perpetrators (OR = 8.23, 95% CI, p < 0.001) were independent predictors of formal reporting. Documented behavioral barriers included stigma (68%), fear of disbelief (45%), and adherence to traditional masculine norms (52%). Our findings demonstrate that male domestic violence victims face substantial behavioral and systemic barriers that prevent help-seeking. Enhanced clinical–forensic training, gender-inclusive response protocols, and public awareness campaigns are essential to provide equitable support and reduce under-reporting. Full article

Intimate partner violence (IPV) remains a persistent public health and human rights challenge globally, with South Africa experiencing some of the highest rates. This study investigates the intersection between partner substance use, controlling behaviours, and women’s risk of experiencing emotional, physical, and sexual IPV. Using nationally representative data from the South African Demographic and Health Survey (SADHS), a weighted sample of 2354 women was analysed. Findings show that 41.8% of women reported that their partners used alcohol and/or drugs, and IPV prevalence among this group was 36.38%. Multivariate logistic regression revealed that partner substance use more than doubled the risk of emotional violence and nearly tripled the risk of physical and sexual violence. Controlling behaviours also emerged as significant predictor, with affected women facing up to nine times higher odds of IPV. These findings highlight the urgent need for integrated intervention strategies that address substance abuse and coercive control within intimate relationships. Prevention efforts must be context-specific, targeting underlying behavioural and gendered power dynamics to reduce IPV and improve women’s safety. Full article
