Temporal and spatial convergence: the major depressive disorder burden attributed to intimate partner violence against women.

Background: There is a strong causal relationship between intimate partner violence and major depressive disorder, which partly endangers women's safety across the life course and potentially affects the development of future generations. The international community has placed a high priority on addressing the intimate partner violence and the resulting burden of mental illness. Data collection needs to be captured across the temporal trend and spatial distribution for major depressive disorder attributed to intimate partner violence, to reflect the priorities and expectations of survivors.Method: This research obtained raw disability-adjusted life years (DALYs) information for major depressive disorder attributed to intimate partner violence from the Global Burden of Disease 2019. Using estimated annual percentage change and two-way fixed effects models, a secondary spatio-temporal analysis of the age-standardized DALYs rate from 1990 to 2019 was performed.Results: In 2019, DALYs lost among women experiencing major depressive disorder (3.16 million) accounted for 37.18% of the DALYs lost worldwide due to intimate partner violence. The age-standardized DALYs rate of major depressive disorder attributed to intimate partner violence was 108.57 per 100,000. The highest was concentrated in the menopausal transition (45-55), with 133.61 per 100,000, and particularly distributed in Uganda (429.31 per 100,000). The early reproductive period (15-19) showed the increasing age-standardized DALYs rate from 1990 to 2019, which was mainly driven by Malaysia (3.73% per year). Furthermore, countries with higher initial levels of the age-standardized DALYs rate were growing faster than those with lower levels.Conclusions: The burden of major depressive disorder attributed to intimate partner violence showed biological and spatial inequality, prioritized intervention should be targeted at vulnerable stage women in their early reproductive period and menopausal transition. Combined political, socio-cultural as well as medical measures to prevent violence and treat major depressive disorder should be implemented and developed.

Vulnerability to different biological stages of the burden of experiencing intimate partner violence leading to major depressive disorder in women. Women in their reproductive years and during the menopausal transition were more vulnerable.Intimate partner violence-induced depressive disorder is trending younger, with an increasing burden on girls aged 15­19 over the past 30 years.The burden of major depressive disorder attributed to intimate partner violence varies increasingly across countries.

Accessing Trauma- and Violence-Informed Breastfeeding Support from Primary Care Providers among Women with Histories of Intimate Partner Violence: An Exploratory Interpretive Description Study.

BACKGROUND: Intimate partner violence (IPV) is a wicked social problem affecting women of all social strata and geographical location, globally. Pregnancy may be a time of heightened risk of IPV and more deleterious outcomes. Breastfeeding - a protective factor for maternal and child well-being - may be jeopardized or more challenging for women experiencing IPV. This study explored the experiences of postpartum women with histories of IPV who sought trauma- and violence-informed breastfeeding support from primary care providers. METHODS: Using interpretive description and philosophically underpinned by intersectionality, in-depth semi-structured interviews were completed at 12-weeks postpartum with five breastfeeding mothers with a history of IPV who sought breastfeeding support from a family physician clinic employing a trauma- and violence-informed (TVIC) model of care. FINDINGS: Four themes and two sub-themes shed light onto the experience of accessing breastfeeding support for women with a history of IPV and the perceived barriers that they faced when attempting to accesses this support, including: 1) The (demoralizing) navigation of the perinatal system; 2) Fostering trust: i) "It's support, but it's also knowledge"; and ii) TVIC: feeling safe and feeling "I mattered"; 3) Informal support: partners, family, and friends; and 4) Baby in focus: overcoming challenges and building confidence. CONCLUSIONS: TVIC may aid in the development of trusting therapeutic relationships, in turn improving access to breastfeeding support, breastfeeding self-efficacy, and breastfeeding success for women who experience violence. Further research on the implementation and evaluation of TVIC for perinatal breastfeeding education and care among women is required.

Discrepancies in perceptions of PTSD symptoms among veteran couples: Links to poorer relationship and individual functioning.

Veteran and intimate partner perceptions of posttraumatic stress disorder (PTSD) may differ, and little is known about how agreement or disagreement on symptom severity is related to relationship satisfaction. Veterans and their partners (N = 199 couples) completed a baseline assessment for a clinical trial evaluating two couple-based PTSD interventions. Veterans completed the PTSD Checklist for DSM-5 (PCL-5). Partners completed the collateral PCL-5 (PCL-5-C), which asked them to rate the severity of the veteran's PTSD symptoms. Both partner and veteran completed the Couples Satisfaction Index (CSI-32). Intraclass correlations (ICC) assessed agreement between PCL-5 and PCL-5-C total and subscale scores, which was low for total PCL and for all subscales (ICC = 0.15-0.46). Actor-Partner Interdependence Models (APIMs; actor-only pattern) tested associations between relationship satisfaction and PTSD symptom severity (total PCL and subscales), and the magnitude and direction of difference between PCL-5 and PCL-5-C (total and subscales). For veterans, more severe total PTSD and negative cognition/mood scores were associated with lower relationship satisfaction, and the direction of discrepancy for negative cognition/mood (i.e., higher veteran-rated PTSD symptoms relative to partner's collateral report) was also associated with lower satisfaction. For partners, more severe collateral-reported symptoms for total PTSD and all four subscales were associated with lower relationship satisfaction; further, a larger discrepancy between veterans' and partners' reports of total PTSD, negative cognition/mood, and hyperarousal were associated with lower satisfaction. These results suggest that partners may have different perceptions of PTSD symptoms, and support the potential of fostering a shared understanding of PTSD symptom severity in couples.

Characterizing Physical Intimate Partner Violence-Associated Injuries Among Adults in Low- and Middle-Income Countries: A Systematic Review.

Forty-two percent of women who experienced intimate partner violence (IPV) reported that their experience of IPV resulted in an injury. This review aims to review the existing literature from low- and middle-income countries (LMICs) on IPV-related injuries as well as identify IPV-related injury patterns and locations. A systematic electronic database search was conducted between August and September 2021 (Prospero ID: CRD42021281519). Five databases yielded 408 articles; 328 remained for title and abstract screening after duplicates were removed. Of the 59 eligible for full-text review, 19 articles were eligible for extraction. After quality assessment, 18 articles were included in the study. Most (56%) studies were observational studies. Studies represented 15 different countries. The majority of the studies (89%) had authors whose institutional affiliation was located in the country where the study took place. Soft tissue injuries were the most commonly reported injury type followed by fractures and burns. The most common injury locations were the head, neck, and face followed by both upper and lower limbs. The most commonly cited injury mechanism was bodily force. The findings of this study echo what has been written in the literature regarding IPV-related injury patterns from high-income countries (HICs). One limitation of this study is that the search only included literature published in English. The injury patterns identified in this article confirm the need for awareness and action on the part of both medical and surgical providers in order to best address IPV in LMICs.

Female Victims of Firearm Intimate Partner Violence: Characterization and Lethality Predictors.

Objective: To characterize the sociological risk factors for firearm intimate partner violence (IPV) among women in Texas, with a focus on lethal predictors to aid in screening and intervention guidelines. Methods: A retrospective medical and forensic chart review was conducted and supplemented by news sources, public police reports, and court records on firearm cases in Houston, TX, from 2018 to 2020. IPV was defined as a cis-gendered female victim of firearm violence from a current or ex-intimate partner. Non-IPV was defined as cis-gendered female victims of firearm violence from strangers, friends/acquaintances, gang, client, or similar relationships. Numeric variables were compared using the Wilcoxon rank-sum test and reported as median [Q1, Q3]. Categorical variables were compared using Fisher's exact test and reported as count (%). Results: A total of 102 cases of IPV were identified. Nonspousal IPV was more prevalent than spousal (65.7% versus 34.3%). Lethal injuries, older age, home location, and head injuries were more prevalent in the IPV cohort. Older age, spousal perpetrator, home shooting location, and history of prior domestic abuse were associated with lethal IPV. There were 31 cases of murder-suicide. During the COVID-19 pandemic, IPV cases increased by 91.3%, with lethal cases increasing by 57.6%. Conclusion: Risk factors for overall IPV and lethal IPV are not the same; therefore, it is imperative that all women, irrespective of race, age, or relationship status, be screened for IPV and prior domestic violence to allow intervention and prevention of lethal IPV. Patients should also be screened for personal or partner access to firearms as firearm IPV is a highly lethal form of violence.

Interpersonal Violence in Five Regions in Asia: Ecological Risk Factors Associated with Perceptions of Justifiability of Violence.

In Asia, rates of interpersonal violence are increasing, with significant regional disparities. However, long-term, continental-scale research considering regional differences across the Asia regions is limited. Guided by the ecological model, we examined five ecological risk factors (low life satisfaction/happiness, economic hardship, neighborhood disadvantage, patriarchal values, and religiosity) associated with perceptions of justification of interpersonal violence (i.e., intimate partner violence [IPV] against wife, child physical abuse, and violence against others) in five regions in Asia (i.e., East, West, Central, South, and Southeast). Using the World Values Survey (n = 32,307), a multigroup multiple regression model was used with robust maximum likelihood estimation using Mplus ver. 8. In the entire Asia sample model, perceptions of justifiability of IPV against wife were positively associated with low life satisfaction/happiness; economic hardship; neighborhood disadvantage; and patriarchal values, while they were negatively associated with religiosity. Perceptions of justifiability of child abuse were positively associated with low life satisfaction/happiness; neighborhood disadvantage; and patriarchal values, while they were negatively associated with economic hardship and religiosity. Perceptions of justifiability of violence against others were positively associated with economic hardship and neighborhood disadvantage, while they were negatively associated with religiosity. Each region presented unique risk factor associations. Considering the high rates of interpersonal violence in Asia, understanding the risk factors associated with perceptions of justifying specific types of interpersonal violence can provide an initial insight into preventing violence in Asia. Further, as many Asians dwelling outside Asian regions are still influenced by their culture, religion, language, and norms of the region of origin, the study findings may shed light on future studies to consider in the interpersonal violence literature.

"It's just the joy of existing": A Photo Elicitation of LGBTQ+ Students' Healthy Intimate Relationships.

This study of LGBTQ+ college students highlights and amplifies the experiences of their healthy intimate relationships. College represents a pivotal time for personal and relationship development for many students, and seeing the positive ways students with historically minoritized gender and sexual identities navigate relationships has value for understanding how sexuality manifests within the current culture. Using a critical constructivist perspective and photo elicitation methods, the study includes students' narratives and visual presentations of their lived experiences thriving in healthy intimate relationships. The findings included three specific areas that supported students' thriving: self-work and self-awareness, fluidity and flexibility, and communication. These findings, and students' relationship images highlight the ways that they thrive through continual affirmative consent and responsibility to themselves and their relationships. Together, these findings provide possibility models to support imagining and educating about LGBTQ+ students' healthy intimate relationships. Findings have potential for informing trainings and resources for LGBTQ+ students, enhancing relationship education by challenging oppressive norms that influence all students, and for questioning the ways university regulations inhibit participants' agency for celebrating their intimacy.

Understanding the link between intimate partner violence exposure and children's self-regulation: The mediating role of parenting stress and warmth.

Intimate partner violence (IPV), affecting approximately 16.3% of U.S. households annually, has detrimental effects on children who witness it, leading to psychological distress, developmental delays, and behavioral issues. Self-regulation, a critical skill in managing attention, emotions, and behaviors essential for cognitive and social development, may be significantly impacted. The negative associations between mothers' experience of IPV and child self-regulation necessitate the examination of the underlying mechanisms, particularly during the sensitive period of early childhood. This study utilized longitudinal data from the Future of Families and Child Wellbeing Study (N = 4338) to investigate the mediating pathways linking mothers' experience of IPV (maternal victimization experiences) during infancy with children's self-regulation at age five. Results suggested that IPV exposure during infancy was longitudinally and negatively associated with children's behavioral and attentional regulation. This association was mediated by elevated parenting stress and decreased maternal warmth. These findings highlight the importance of programs aimed at reducing IPV and supporting mothers affected by IPV, considering their vital roles in nurturing healthy child self-regulation skills.

Prevalence and Correlates of Intimate Partner Violence Among Women and Men in Mexico: A Systematic Review and Meta-analysis.

This article presents the first systematic review and meta-analysis of the prevalence and correlates of different forms of intimate partner violence (IPV) among women and men in Mexico. To identify studies, a comprehensive search strategy was developed and executed across 11 databases (Academic Search Complete, APA PsycInfo, CINAHL, Cochrane CENTRAL, Embase, International Bibliography of the Social Sciences, LILACS, MEDLINE, SciELO, Sociological Abstracts, Web of Science). From the 1,746 studies screened, 155 full-text articles were reviewed, and this systematic review included 27 studies involving 249,557 participants to determine the prevalence of physical, psychological, sexual, threats, and other forms of IPV, according to gender and other sociodemographic characteristics. Overall IPV prevalence was 16.4%, with significant differences across pregnant and non-pregnant women. Physical IPV prevalence was 14.7%, revealing higher rates in men (29.5%) compared to women (14.2%). Psychological IPV prevalence was 27.3% and sexual IPV was at 6.6%, with differences across evaluation periods. Threats and other IPV forms showed a prevalence rate of 14.2% and 21.5%. Meta-regression analyses included gender, education, marital status, rural residency, pregnancy, age, and evaluation period. This study demonstrates that IPV is a critical public health concern in Mexico, impacting both women and men. It shows the vulnerability of rural residents, youth, and pregnant women. However, understanding IPV complexities in Mexico requires nuanced considerations of demographic and situational contexts. Urgent initiatives from municipal, state, and federal governments are needed to combat IPV, focusing on prevention and support for affected individuals.

Multi-level predictors of young people's attitudes towards gender biases concerning rape, sexual and domestic violence in intimate relationships among young people, Ebonyi State, Southeast Nigeria.

This study assessed multi-level factors that shape young people's attitudes towards gender biases about rape, sexual, and domestic violence in intimate relationships. This cross-sectional study was undertaken in three urban and three rural communities in Ebonyi State, southeast Nigeria. Data were collected from 1,020 young people using an interviewer-administered questionnaire. Descriptive and logistic regression analyses were performed using STATA. Findings revealed that most(64%) young people agree that when a girl doesn't physically fight back, you cannot really say it was rape. Many agreed that a girl who is raped is promiscuous or has a bad reputation (50%) and usually did something careless to put herself in that situation(45%). Young girls were approximately 2 times more likely to have positive attitudes towards sexual violence, rape, and domestic violence in intimate relationships than young boys (OR=1.5;P<0.01). Multi-level strategies to effectively address adverse gender norms and inequalities in intimate relationships are highly recommended.

Cette étude a évalué les facteurs à plusieurs niveaux qui façonnent les attitudes des jeunes à l'égard des préjugés sexistes concernant le viol, la violence sexuelle et domestique dans les relations intimes. Cette étude transversale a été entreprise dans trois communautés urbaines et trois communautés rurales de l'État d'Ebonyi, au sud-est du Nigeria. Les données ont été recueillies auprès de 1 020 jeunes à l'aide d'un questionnaire administré par un intervieweur. Des analyses de régression descriptive et logistique ont été effectuées à l'aide de STATA. Les résultats ont révélé que la plupart (64 %) des jeunes conviennent que lorsqu'une fille ne se défend pas physiquement, on ne peut pas vraiment dire qu'il s'agit d'un viol. Beaucoup conviennent qu'une fille violée est une promiscuité ou a une mauvaise réputation (50%) et a généralement fait quelque chose de négligent pour se mettre dans cette situation (45%). Les jeunes filles étaient environ 2 fois plus susceptibles d'avoir des attitudes positives à l'égard de la violence sexuelle, du viol et de la violence domestique dans les relations intimes que les jeunes garçons (OR=1,5 ; P<0,01). Des stratégies à plusieurs niveaux pour lutter efficacement contre les normes de genre défavorables et les inégalités dans les relations intimes sont fortement recommandées.

Intimate partner violence during pregnancy: To screen or not to screen?

Intimate partner violence (IPV) during pregnancy emerges as a compelling and urgent concern within the domain of public health, casting a long shadow over a substantial cohort of women. Its pernicious consequences extend beyond the individual, enveloping the well-being of both the mother and the fetus, giving rise to an elevated risk of preterm birth, low birth weight, fetal harm, and maternal psychological distress, including depression, anxiety, post-traumatic stress disorder, and, tragically, maternal mortality. Despite the prevalence of IPV being comparable to other conditions like gestational diabetes and preeclampsia, a universal screening protocol for IPV remains absent globally. We reviewed the clinical guidelines and practices concerning IPV screening, painstakingly scrutinizing their contextual nuances across diverse nations. Our study unveils multifaceted challenges of implementing universal screening. These hurdles encompass impediments to victim awareness and disclosure, limitations in healthcare providers' knowledge and training, and the formidable structural barriers entrenched within healthcare systems. Concurrently, we delve into the potential biomarkers intricately entwined with IPV. These promising markers encompass inflammatory indicators, epigenetic and genetic influences, and a diverse array of chemical compounds and proteins. Lastly, we discussed various criteria for universal screening including (1) valid and reliable screening tool; (2) target population as pregnant women; (3) scientific evidence of screening programme; and (4) integration of education, testing, clinical services, and programme management to minimise the challenges, which are paramount. With the advancement of digital technology and various biomarkers identification, screening and detecting IPV in clinical settings can be conducted systemically. A systems-level interventions with academia-community-indutrial partnerships can help connect pregnant women to desire support services to avoid adverse maternal and child health outcomes.

"As I dropped the phone, she slapped me for the first time": Experiences of intimate partner violence among Nigerian men during COVID-19 restrictions.

Limited literature exists on men's experiences with intimate partner violence (IPV) during the COVID-19 lockdown, especially in resource-constrained settings like Nigeria. We investigated the prevalence, risk factors, and lifetime experiences of IPV among men in Nigeria, during COVID-19 restrictions. Using a mixed methods design, we interviewed 420 married men with a structured questionnaire and conducted 20 in-depth interviews. Logistic regression and a framework approach were used for data analysis. Approximately 86.4% of respondents (n=363) experienced IPV at some point in their lifetime. The prevalence of IPV during the COVID-19 restrictions was 76.2% (n=320). Over a lifetime, verbal (67.4%), physical (78.1%), and sexual coercion (81.0%) were the most common forms of IPV. During the COVID-19 lockdown, the corresponding proportions were 48.6%, 69.5%, and 57.4%, respectively. Male- and female-perpetrated IPV over a lifetime (88.3% vs 87.6%) and during COVID-19 restrictions (88.3% vs 81.4%) were similar (p>0.05). Older age, non-Muslim religion, longer marital duration, partner's profession, and no formal education were associated with higher IPV risk. Home confinement, financial stress, childbirth, disrespect towards spouse's parents, emotional detachment, disputes about child discipline, and suspected infidelity contributed to IPV. Men's active involvement in family life, improved communication, and increased transparency emerged as protective factors. Our findings highlight the high rates of IPV during the pandemic, with men as both perpetrators and victims. Future epidemic preparedness plans should prioritize IPV prevention strategies that enhance partner communication, promote male involvement in family life, address the gender education gap, and provide support services.

Domestic violence and associated factors among pregnant women in sub-Saharan African countries from the recent demographic and health survey data: a multilevel analysis.

Introduction: Intimate partner violence (IPV) is a human rights violation that often involves violence against women, which appears to be the most prevalent type of abuse. IPV is a global public health issue with major human rights violations. Pregnant women's IPV needs special consideration because of the possible harm that might happen to mothers and their fetuses. The enormous global public health issue of IPV affects physical, mental, and sexual transgressions. Even though there were studies conducted on IPV among women, few studies were conducted among pregnant women in sub-Saharan African countries. Therefore, this study revealed IPV and associated factors among pregnant women from the recent Demographic and Health Survey (DHS) in sub-Saharan African countries. Methods: Multilevel logistic regression analysis used data from the recent sub-Saharan African countries DHS was carried out using this secondary data. For this study, pregnant women between the ages of 15 and 49 were included; the total sample size was 17,672. Multilevel logistic regression models were calibrated to determine the associated factors at the individual and community level with IPV, with a 95% CI and AOR. Results: The prevalence of IPV among pregnant women in 23 sub-Saharan African countries was 41.94%, with a 95% CI of 40.82 to 43.06%. Poorer and poorest [AOR = 1.92; 95% CI: (1.01, 3.67)] and [AOR = 2.01; 95% CI:(1.02, 3.92)], partner alcohol drink [AOR = 3.37;95% CI:(2.21, 5.14)], and no partner education [AOR = 2.01;95% CI:(1.12, 3.63)] were statistically associated factors with IPV among pregnant women. Conclusion: The prevalence of IPV among pregnant women in sub-Saharan African countries was high (41.94%). Low economic status, partner drinking alcohol, and partner no education were the associated factors of IPV. This finding provides clues for policymakers and other organizations concerned about women.

Prevalence and Correlates of Intimate Partner Violence in the Perinatal Period in a Representative Sample of Quebec Mothers.

Using a nationally representative sample of 1,264 biological mothers of children aged between 6 months and 5 years, this study identified the prevalence estimates of intimate partner violence occurring in the perinatal period (IPV-PP) and examined the associations between IPV-PP and various characteristics. Findings show that 10.9% of mothers reported victimization to at least one intimate partner violence episode during the perinatal period. Younger maternal age at childbirth, drug consumption, being a single mother, higher parental stress due to the child's temperament, and higher stress due to family and extrafamilial obligations were all associated with IPV-PP. Findings emphasized that IPV-PP is indeed an important public health matter in Quebec. Interventions should focus on victimization screening during the perinatal period and on enhancing victims' security and well-being.

Encountering and Identifying Different Forms of Domestic Violence in Shelters and Community Care Services in Finland During the COVID-19 Pandemic.

During the COVID-19 pandemic, restrictions such as lockdowns and social distancing have been used to control coronavirus. These restrictions may increase the risk of domestic violence (DV) and discourage victims from getting help. We examined the consequences that the pandemic had on different forms of DV and different victim groups of DV. An online survey of shelter clients (N = 47), interviews with clients in community care services (N = 2), and eight focus group interviews with professionals (N = 27) working in shelters and community care services were used for data. We used a mixed-methods approach in the analysis, which showed that clients in shelters reported more violence during the pandemic than prepandemic. Psychological, controlling, and financial violence increased the most during the pandemic, according to the survey data. Coercive control was the most visible type of violence from the perspective of three vulnerable groups: intimate partners, children, and migrants. The research findings will help us arrange services to identify and better manage pandemic lockdown-associated violence.

Co-occurring Intimate Partner Violence, Mental Health, Human Immunodeficiency Virus, and Parenting Among Women: A Scoping Review.

Little research exists on the human immunodeficiency virus (HIV)-intimate partner violence (IPV)-mental health (MH) syndemic impact on parenting. The objective of this scoping review is to identify and summarize the available evidence regarding the syndemic relationship between HIV or Acquired Immune Deficiency Syndrome (AIDS), IPV, and poor MH among mothers and caregivers who identify as women. We conducted the review according to the Joanna Briggs Institute and Preferred Reporting Items for Systematic reviews and meta-analyses extension for scoping reviews guidelines, a comprehensive search was conducted from 2001 to September 2023. The inclusion criteria targeted studies examining at least two of the HIV, IPV, or MH epidemics among participants and their syndemic impact on parenting. Both qualitative and quantitative studies were included. Covidence software was used to screen and extract data. Twenty-three studies were included in the analysis. Most of the studies were conducted in the United States. Furthermore, all the studies used quantitative research designs, with most being longitudinal. Most of the research was concentrated on the IPV-MH syndemic with no research found on the HIV-IPV syndemic impact on parenting. Research on the HIV-IPV-MH syndemic found that an HIV diagnosis exacerbated the negative impacts of IPV-MH on parenting. Research on IPV-MH showed that this syndemic significantly influences parenting, leading to less nurturing and more punitive behaviors. Studies did not find a direct association between IPV and harsh parenting practices, the relationship was mediated by poor MH. Studies examining the HIV-MH syndemic found that anxiety and maternal depression were the most frequent MH disorders. The review revealed that living with the different syndemics, (IPV-MH-HIV, HIV-MH, and IPV-MH) adversely affects parenting practices, resulting in harsher parenting.

Interpersonal Violence Against Indigenous Sámi and Non-Sámi Populations in Arctic Sweden and the Mediating Effect of Historical Losses and Discrimination.

The prevalence of interpersonal violence has been reported at higher levels among Indigenous than non-Indigenous populations worldwide, but has not been thoroughly investigated among the Sámi population in Sweden. The aims of this study were to investigate: (1) the prevalence of emotional, physical, and sexual violence and violence by intimate partners, family members, acquaintances, and strangers among participants identifying as Sámi or Swedish, (2) whether reporting experiences of historical losses and discrimination mediated the anticipated association between identifying as Sámi and reporting experiences of violence, and (3) whether background characteristics were associated with reporting experiences of violence. Cross-sectional questionnaire data collected in 2021 for the "Health and Living conditions in Sápmi" study were used. All adults in an arctic region in Sweden were invited to participate (response rate: 41%). Respondents self-identifying as Sámi (n = 375; 24.7%) or Swedish (n = 1,144; 75.3%) were included in this study. Sámi respondents of both sexes more often reported violence by an acquaintance or stranger. Likewise, more Sámi than Swedish women reported family violence (16.4% vs. 9.2%), but there was no difference concerning intimate partner violence (13.3% vs. 15.4%). Mediation analyses revealed strong positive indirect effects of historical losses and discrimination on the different types of violence. Being female was the strongest predictor of reporting intimate partner violence, and younger age was associated with violence by all perpetrators except family members. In conclusion, interpersonal violence was more often reported by Sámi respondents, but the association was explained in full by experiences of historical losses and discrimination. The results underline the importance of a life-course and even intergenerational and historical perspectives when investigating interpersonal violence.

Alcohol use and intimate partner violence victimization among young adults with a history of perpetration: An ecological momentary assessment study.

BACKGROUND: Intimate partner violence (IPV) is a major public health concern among young adults and has shown a consistent association with alcohol use. However, previous research has used cross-sectional and daily diary designs that may fail to pinpoint the effects of alcohol use within several hours of IPV occurring. The present study used novel ecological momentary assessment (EMA) methods to investigate the bidirectional effect of alcohol use and IPV victimization among young adults with a history of IPV perpetration. METHODS: One hundred and sixty-eight young adults (age 18-25 years) in a dating relationship who reported IPV perpetration in the past year completed 28 days of randomly prompted EMA surveys (four surveys daily). The effect of alcohol use on IPV victimization and the effect of IPV victimization on alcohol use were examined. RESULTS: The results indicated that alcohol use co-occurs with psychological and physical IPV victimization. Further, alcohol use significantly increased the odds of physical (OR = 4.94; 95% CI = 2.24-10.87) and sexual (OR = 4.66; 95% CI = 1.64-13.22) IPV victimization, but not psychological IPV victimization, in the subsequent EMA survey. Finally, IPV victimization did not significantly increase the odds of reporting alcohol use in the subsequent EMA survey. CONCLUSIONS: Using alcohol is proximally related to IPV victimization among those with a history of IPV perpetration. Intervention efforts would benefit from adapting EMA methods to provide resources the moment they are needed.

On-Chip Synthesis of Quasi-2D Semimetals from Multi-Layer Chalcogenides.

Reducing the dimensions of materials from three to two, or quasi-two, provides a fertile platform for exploring emergent quantum phenomena and developing next-generation electronic devices. However, growing high-quality, ultrathin, quasi2D materials in a templated fashion on an arbitrary substrate is challenging. Here, the study demonstrates a simple and reproducible on-chip approach for synthesizing non-layered, nanometer-thick, quasi-2D semimetals. In one implementation, this method starts with thin semiconducting InSe flakes of below 20 nm in thickness with nickel deposited on top, followed by a low-temperature annealing step that results in a controlled transformation of the layered InSe to a non-layered, crystalline semimetal via reaction with the laterally diffusing nickel. Atomic resolution microscopy reveals the transformed semimetal to be Ni3In2Se2 with a Kagome-lattice structure. Moreover, it is demonstrated that this synthesis method is generalizable by transforming 2D layered chalcogenides such as SnS and SnSe employing Ni and Co to non-layered semimetals, paving the way for engineering novel types of devices.

Anoxic Brain Injury: A Subtle and Often Overlooked Finding in Non-Fatal Intimate Partner Strangulation.

BACKGROUND: A paucity of literature exists dedicated to the identification of anoxic brain injury in patients that survive non-fatal intimate partner strangulation (NF-IPS). While some individuals report experiencing symptoms of brain hypoxia followed by a loss of consciousness, other individuals report symptoms of brain hypoxia prior to amnesia, rendering some unable to recall loss of consciousness (LOC). OBJECTIVE: Using a standardized clinical assessment tool, the purpose of this retrospective analysis is to describe anoxic brain injury symptom prevalence in a sample of patients reporting NF-IPS. METHODS: One hundred and ninety-one unique patients, reporting a total of 267 strangulation events, were assessed by a member of the Shasta Community Forensic Care Team utilizing the Strangulation Hypoxia Anoxia Symptom TBI Assessment (SHASTA) tool. The sample is 98% female and includes adult patients ages 18-68. Examination records were categorized based on the presence or absence of hypoxia and anoxia symptoms. This manuscript utilizes the STROBE checklist. RESULTS: Amnesia was reported in 145 of the 267 strangulations (54.3%). Of those, 74 reported LOC (51.0%) while 71 did not recall LOC (49.0%). CONCLUSIONS: Within our sample, 49% of patients with amnesia did not recall losing consciousness, demonstrating that LOC is an imperfect measure of anoxia for patients following NF-IPS. Healthcare providers examining NF-IPS patients should inquire about additional symptoms of hypoxia and amnesia, which can be captured on the SHASTA tool.
