Research on the intergenerational transmission of intimate partner violence (IPV), or the "cycle of violence," from childhood exposure (G1) to the perpetration of IPV in adulthood relationships (G2), has increased over the past decades. The link between childhood exposure to interparental violence and future IPV perpetration is largely explained by postulations from social and psychological theories, such as social learning theory. These theories provide claims regarding IPV transmission pathways and the mechanisms underpinning the transmission. However, evidence from extant theory-informed studies on the cycle of violence has generated several null and counter-predictive findings, which raises questions about the nature of the theory-informed research, as well as methodological questions. This systematic review sought to analyze how existing studies applied specific theories to research IPV transmission, and the mechanisms underpinning these transmissions. Following the PRISMA procedure for systematic reviews, we reviewed empirical articles from five databases (Scopus, Web of Science, CINAHL, Informit, and PubMed) published between 1990 and 2024. Results from the 30 included studies were synthesized under three theoretical categories, namely: social, psychological, and cultural theories. Under each theoretical category, we found inconsistent evidence, lack of empirical examination of theory-driven variables, and reductionist approaches, in terms of how claims from the theories are applied in research on IPV transmission. Research guided by a singular theoretical framework presented inconsistencies compared to those applying a multi-theory approach. As a result, we recommend an integrated theoretical model that considers the comprehensive and transactional process/factors that underpin IPV transmission.
This study examined current evidence on children's pathways into commercial sexual exploitation (CSE) in the United States to determine if characteristics, vulnerabilities, and social contexts were distinguishable by age, gender, race/ethnicity, and location. Using Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines, peer-reviewed studies and grey literature were included if they were focused on CSE pathways prior to age 18, available in English, U.S. based, and published in or after 2013. In total, 1,989 articles were screened and 306 were eligible for full-text review. In total, 22 studies were analyzed. Nine studies focused on cis girls or women. No studies exclusively focused on CSE among cis boys, gender diverse children, children identifying as LGBTQ+, or children initiated from infancy through preadolescence. Findings indicate that boys and girls at different life stages were initiated into CSE by five pathways, including: (a) family members and caregivers' paramours; (b) romantic partners; (c) peers, friends, and acquaintances; (d) strangers; and (e) circumstantial need. Girls and boys in infancy, toddlerhood, and preadolescence and across rural-urban classifications were exploited by family members, parent's romantic partners, and acquaintances known to their family. Adolescent girls, including those with intellectual disabilities, were trafficked by boyfriends, strangers, and out of circumstantial needs. This is the first review to provide a contemporary overview of dynamics that marked children's CSE pathways from infancy through adolescence. Findings revealed need for future research on CSE-impacted boys, gender diverse and LGBTQ+ children, and intellectually challenged children across early life stages and geographic areas.
Literature on stress and intimate partner violence (IPV) has primarily focused on stress as an outcome of women's experience of IPV. However, stress may also be a predictor of male-perpetrated IPV. To improve our understanding of how theoretical approaches to stress have been applied to IPV research, we conducted a sub-analysis of a broader systematic review to identify published literature that examines theoretical approaches to stress as a predictor of male-perpetrated IPV. We conducted a search of nine electronic databases and assessed title/abstract and full texts according to pre-defined inclusion and exclusion criteria. Two reviewers categorized included studies into different theoretical groupings and sub-groupings. Data were extracted according to a data extraction template developed for the review, establishing consistency in a pilot data extraction phase. The review identified 27 articles that addressed the following theories of stress: general stress theory, life course theory, occupational stress theory, vulnerability theory, and family stress theory. Each of these sub-theories focuses on different forms of stress, for example, life course theory specifically focuses on stressful early life experiences, including adverse childhood events, whereas occupational stress theory focuses on workplace-related stressors that may result in increased male-perpetrated IPV. Analysis of measurement of stress variables indicated that measurement of stress varies widely across studies and primarily relies on self-reports. Consideration of stress as a predictor of IPV provides important insights into preventable and modifiable targets for intervention. Additional research on mechanisms and pathways between stress and IPV is needed.
Violence against women with disabilities has received more attention in recent years recognizing the intersectionality of experiences of abuse, yet little is known about the less visible forms of disability such as speech and language disorders. This review aimed to identify and synthesize existing literature exploring the relationship between speech and language disorders and victimization, including child sexual abuse (CSA), exposure to domestic violence in childhood, and intimate partner violence (IPV) and sexual assault in adulthood. Five electronic databases were systematically searched using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews guidelines. Studies were included if they were English-language peer-reviewed articles or grey literature publications focusing on domestic violence and/or sexual assault and speech and language disorders. Twenty studies met the inclusion criteria. The findings showed a clear link between childhood exposure to domestic violence and/or CSA and speech and language disorders. Women with speech and language disorders appear to be at heightened risk of IPV and sexual assault relative to the general population. Nonfatal strangulation emerged as a growing area of concern in the literature with acute and chronic symptoms requiring treatment from speech and language therapists. Practice implications include enhanced training at the undergraduate and professional level for therapists to better identify and respond to suspected abuse in their patients. Emergency and specialist support services need protocols and training to better support women with speech and language disorders. Future research should examine the help-seeking behavior of women with speech and language disorders post-victimization and collect longitudinal data to understand the long-term consequences of abuse.
Adverse childhood experiences (ACEs) can be extremely traumatic, and their impact on health throughout the life course has been a public policy issue all around the world. Oral health conditions significantly influence quality of life, but its relationship with ACEs among children and adolescents is not well defined. This systematic review investigated the association between ACEs and oral health outcomes in children and adolescents. The search was conducted across six databases and the gray literature, with no restrictions. It included studies evaluating the association between ACEs and oral health outcomes (oral health condition, utilization of dental services, oral hygiene habits, or oral health related to quality of life) in individuals aged 0 to 19. Data of included studies were extracted and methodological quality was assessed. Meta-analysis was used for quantitative synthesis, and the Grading of Recommendations Assessment, Development and Evaluation approach assessed evidence certainty. From the 12 included studies, 11 had a cross-sectional design, and 1 was a cohort study. Seventeen types of ACEs were investigated, including neglect; violence between parents or caregivers; alcohol and substance abuse; and peer, community, and collective violence. The methodological quality compliance ranged between 38% and 100%. The meta-analysis revealed associations between ACEs and lower use of dental services, toothache, gingival bleeding, and dental cavities. Cumulative exposure to more than three ACEs was associated with poorer oral health. The certainty of the evidence varied from low to very low. These results highlight that children and adolescents with ACEs are more likely to present higher oral health problems, including decreased use of dental services.
