Risk of interpersonal violence during and after pregnancy among people with schizophrenia: a population-based cohort study.

Schizophrenia is associated with increased risk of experiencing interpersonal violence. Little is known about risk specifically around the time of pregnancy. This population-based cohort study included all individuals (aged 15-49 yr) listed as female on their health cards who had a singleton birth in Ontario, Canada, between 2004 and 2018. We compared those with and without schizophrenia on their risk of an emergency department (ED) visit for interpersonal violence in pregnancy or within 1 year postpartum. We adjusted relative risks (RRs) for demographics, prepregnancy history of substance use disorder and history of interpersonal violence. In a subcohort analysis, we used linked clinical registry data to evaluate interpersonal violence screening and self-reported interpersonal violence during pregnancy. We included 1 802 645 pregnant people, 4470 of whom had a diagnosis of schizophrenia. Overall, 137 (3.1%) of those with schizophrenia had a perinatal ED visit for interpersonal violence, compared with 7598 (0.4%) of those without schizophrenia, for an RR of 6.88 (95% confidence interval [CI] 5.66-8.37) and an adjusted RR of 3.44 (95% CI 2.86-4.15). Results were similar when calculated separately for the pregnancy (adjusted RR 3.47, 95% CI 2.68-4.51) period and the first year postpartum (adjusted RR 3.45, 95% CI 2.75-4.33). Pregnant people with schizophrenia were equally likely to be screened for interpersonal violence (74.3% v. 73.8%; adjusted RR 0.99, 95% CI 0.95-1.04), but more likely to self-report it (10.2% v. 2.4%; adjusted RR 3.38, 95% CI 2.61-4.38), compared with those without schizophrenia. Among patients who did not self-report interpersonal violence, schizophrenia was associated with an increased risk for a perinatal ED visit for interpersonal violence (4.0% v. 0.4%; adjusted RR 6.28, 95% CI 3.94-10.00). Pregnancy and postpartum are periods of higher risk for interpersonal violence among people with schizophrenia compared with those without schizophrenia. Pregnancy is a key period for implementing violence prevention strategies in this population.

Disability and Interpersonal Violence in the Perinatal Period.

To compare the risk of interpersonal violence experienced by pregnant and postpartum individuals with physical disabilities, sensory disabilities, or intellectual or developmental disabilities with those without disabilities, and to examine whether a prepregnancy history of interpersonal violence puts individuals with disabilities, at excess risk of interpersonal violence in the perinatal period. This population-based study included all individuals aged 15-49 years with births in Ontario, Canada, from 2004 to 2019. Individuals with physical (n=147,414), sensory (n=47,459), intellectual or developmental (n=2,557), or multiple disabilities (n=9,598) were compared with 1,594,441 individuals without disabilities. The outcome was any emergency department visit, hospital admission, or death related to physical, sexual, or psychological violence between fertilization and 365 days postpartum. Relative risks (RRs) were adjusted for baseline social and health characteristics. Relative excess risk due to interaction (RERI) was estimated from the joint effects of disability and prepregnancy violence history; RERI>0 indicated positive interaction. Individuals with physical (0.8%), sensory (0.7%), intellectual or developmental (5.3%), or multiple disabilities (1.8%) were more likely than those without disabilities (0.5%) to experience perinatal interpersonal violence. The adjusted RR was 1.40 (95% CI 1.31-1.50) in those with physical disabilities, 2.39 (95% CI 1.98-2.88) in those with intellectual or developmental disabilities, and 1.96 (95% CI 1.66-2.30) in those with multiple disabilities. Having both a disability and any violence history produced a positive interaction for perinatal interpersonal violence (adjusted RERI 0.87; 95% CI 0.47-1.29). The perinatal period is a time of relative high risk for interpersonal violence among individuals with pre-existing disabilities, especially those with a history of interpersonal violence.

Trajectories and correlates of opioid prescription receipt among patients experiencing interpersonal violence.

Interpersonal violence increases vulnerability to the deleterious effects of opioid use. Increased opioid prescription receipt is a major contributor to the opioid crisis; however, our understanding of prescription patterns and risk factors among those with a history of interpersonal violence remains elusive. This study sought to identify 5-year longitudinal patterns of opioid prescription receipt among patients experiencing interpersonal violence within a large healthcare system and sociodemographic and clinical characteristics associated with prescription patterns. This secondary analysis examined electronic health record data from January 2004-August 2019 for a cohort of patients (N = 1,587) referred for interpersonal violence services. Latent class growth analysis was used to estimate trajectories of opioid prescription receipt over a 5-year period. Standardized differences were calculated to assess variation in sociodemographic and clinical characteristics between classes. Our cohort had a high prevalence of prescription opioid receipt (73.3%) and underlying co-morbidities, including chronic pain (54.6%), substance use disorders (39.0%), and mental health diagnoses (76.9%). Six prescription opioid receipt classes emerged, characterized by probability of any prescription opioid receipt at the start and end of the study period (high, medium, low, never) and change in probability over time (increasing, decreasing, stable). Classes with the highest probability of prescription opioids also had the highest proportions of males, chronic pain diagnoses, substance use disorders, and mental health diagnoses. Black, non-Hispanic and Hispanic patients were more likely to be in low or no prescription opioid receipt classes. These findings highlight the importance of monitoring for synergistic co-morbidities when providing pain management and offering treatment that is trauma-informed, destigmatizing, and integrated into routine care.

Interpersonal Violence, PTSD, and Substance Use Types among Women Receiving Substance Use Treatment

Objective: Many women receiving substance use treatment report histories of interpersonal violence (IV) victimization, including physical and sexual assault. IV is a risk factor for mental and behavioral health difficulties such as posttraumatic stress disorder (PTSD) and substance use disorder (SUD). Consistent with the self-medication hypothesis, PTSD may explain elevated SUD among IV survivors. Yet, few studies have investigated whether PTSD may have differential mediating effects for different substances, which has significant treatment implications. Methods: In 124 women (M age = 35.37, SD = 11.90) in substance use treatment, we examined PTSD symptoms as a mediator between IV and severity of different types of substance use, including alcohol, cannabis, cocaine, and opioid use. Participants completed self-report measures including the ASSIST, PCL-5, and LEC-5. Data were analyzed using path analysis in Mplus 8.3. Both dichotomous and continuous outcomes of problematic substance use outcomes were examined. Results: Most women (53.3%) reported problematic substance use with at least one substance, including opioids (39.7%), cocaine (13.0%), alcohol (9.6%), and cannabis (5.6%). Most (83.2%) of the sample reported at least one IV incident. On average, women reported clinically significant PTSD symptom severity. When problematic substance use was examined dichotomously, findings revealed significant indirect effects from IV exposure to opioid (β = 0.10, p = .010) and cocaine use (β = 0.07, p = .039) via elevated PTSD symptoms. There were no significant indirect effects for problematic alcohol (β = 0.03, p = .260) or cannabis use (β = 0.02, p = .562). When substance use was examined continuously, results revealed significant indirect effects from IV exposure to opioid (β = 0.09, p = .017), cocaine use (β = 0.09, p = .015), and alcohol use (β = 0.08, p = .020) via elevated PTSD symptoms. Indirect effects for cannabis use remained nonsignificant (β = 0.05, p = .100). Conclusions: IV survivors may be particularly at risk for opioid and cocaine misuse because of elevated PTSD symptoms. Treatments that integrate PTSD and SUD are needed to simultaneously target traumatic stress and substance use. Women with opioid and cocaine misuse may particularly benefit from trauma-focused exposure-based psychotherapy to reduce symptoms of PTSD, and thus, decrease opioid and cocaine misuse.

Improving the Forensic Documentation of Injuries Through Alternate Light: A Researcher-Practitioner Partnership.

An alternate light source (ALS) is a practitioner-driven technology that can potentially improve the documentation of injuries among victims of interpersonal violence. However, evidence-based guidelines are needed to incorporate and document an ALS skin assessment into a forensic medical examination that accurately reflects the science, context of forensic nursing practice, trauma-informed responses, and potential impact on criminal justice stakeholders. This article introduces the forensic nursing community to a current translation-into-practice project focused on developing and evaluating an ALS implementation program to improve the assessment and documentation of bruises among adult patients with a history of interpersonal violence. Our researcher-practitioner collaboration uses theory-based approaches that consider both the developed program's practice context and stakeholder impact. The goal is to provide evidentiary support for adult victims of violence and a more equitable forensic nursing practice that benefits diverse patient populations.

Families With Violence Exposure and the Intergenerational Transmission of Somatization.

Introduction:Adults who have histories of childhood trauma have been noted to display greater somatization, dissociative symptoms and affect dysregulation. What happens in the parent-child relationship when those traumatized children become parents? A potential link to somatization in the child has been suggested by several prior studies. Children who have early attachment disturbances had more physical complaints if their mothers displayed less maternal sensitivity during observed parent-child interactions. Yet, the intergenerational link between maternal and child somatization has not been sufficiently explored in a longitudinal study in order to understand the potential impact of maternal trauma history and related psychopathology on subsequent child somatization and psychopathology.MethodsThis paper examined prospective, longitudinal data of 64 mother-toddler dyads (mean age = 2.4 years, SD = 0.7) who were later studied when children had a mean age of 7 years. Mothers with and without histories of interpersonal violence (IPV; physical/sexual abuse and/or family violence exposure) were included. Mothers with IPV histories were oversampled. Linear and Poisson regression models were used to test the associations between maternal IPV-related post-traumatic stress disorder (PTSD) with maternal somatization severity when children were toddlers, and between maternal somatization and maternal interactive behaviors with child somatization by maternal report and clinician-rated assessment at school-age.ResultsMaternal PTSD severity was significantly associated with increased maternal somatization severity (p = 0.031). Maternal somatization severity during the child's early childhood predicted both maternal report of child somatization (p = 0.011) as well as child thought problems (p = 0.007) when children were school-aged. No association was found between maternal somatization and child-reported psychopathology. The study did not find that maternal alexithymia, caregiving behaviors or child exposure to violence contributed significantly to the model examining the association between maternal and child somatization.ConclusionThe results are in line with the hypothesis of intergenerational transmission of somatization in the context of IPV and related maternal PTSD during formative early development. We interpret this as an expression of psychological distress from mother to child, as maternal trauma and pathology affect the caregiving environment and, thus, the parent–child relationship. The authors conclude with a discussion of implications for parent–infant and early childhood intervention.

Impulsive and aggressive traits and increased peripheral inflammatory status as psychobiological substrates of homicide behavior in schizophrenia

Background and objectivesAn association between inflammation and psychopathological domains of psychotic disorders is widely acknowledged; however, the involvement of inflammatory processes in the underlying pathophysiology of violent behavior in schizophrenia is yet to be elucidated. In this study, we aimed to address the differences in impulsive and aggressive traits as well as C-reactive protein (CRP) to albumin ratio (CAR) as a marker of inflammation between schizophrenia patients with a history of homicide and those without any history of interpersonal violence or criminal background. MethodsThe study population consisted of 80 male DSM-5 schizophrenia patients who were classified into two groups: homicidal (n=40) and non-violent (n=40). Impulsive and aggressive traits were evaluated with Barratt Impulsivity Scale-11 (BIS-11), and the Buss-Warren Aggression Questionnaire (BWAQ), respectively. For the calculation of CAR, the CRP and albumin levels were obtained from the file records of routine blood screenings performed in the month before the patients were included in the study. ResultsWhen adjusted for age, all subscale scores of the BIS-11 as well as BWAQ Total, Physical and Hostility scores were significantly higher in the homicidal group than in the control group. CRP and CAR were significantly higher, and albumin was significantly lower in the homicidal patients than the controls when adjusted for age, body-mass index and smoking status. Univariate and stepwise multivariate regression models indicated that BIS-11 Non-planning, BWAQ Total, BWAQ Hostility and CAR were independent predictors of belonging to the homicidal patient group, after stepwise adjustment for all potential confounders. ConclusionsOur findings suggest that certain impulsive and aggressive traits as well as CAR, as a proxy marker of peripheral inflammation, may contribute towards homicidal tendencies and may predict a specific predisposition towards lethal violence in schizophrenia. The study highlights inflammation as a potential biological correlate of a specific behavioral phenotype (homicide) in schizophrenia.

The Association Between Interpersonal Violence and Unstable Housing Among Veterans.

Despite programs to address housing for Veterans, they continue to be at high risk of unstable housing. Interpersonal violence is also highly prevalent among Veterans and may contribute to unstable housing. Our study aimed to determine whether interpersonal violence was associated with unstable housing among Veterans, and how this association was influenced by common co-occurring conditions such as substance use and mental illness. Veterans in the Mind Your Heart Study (N = 741) completed survey data on history of interpersonal violence and access to housing in the prior year. Interpersonal violence was defined as experiencing sexual violence, physical violence, or mugging/physical attack using the Brief Trauma Questionnaire. Multivariable models examined associations between interpersonal violence and unstable housing. Primary models were adjusted for age and sex. Potential explanatory factors were added in subsequent models, including marital status, education, income, substance use disorder, PTSD, and other mental illness. Veterans who had experienced interpersonal violence had almost twice the odds of unstable housing after adjustment for age and sex (AOR 1.9, 95% CI 1.2-3.0). This association was attenuated in the fully adjusted model including substance use, PTSD, and other mental illness, illustrating the interdependence of these factors (AOR 1.5, 95% CI 0.91-2.5). Subtypes of interpersonal violence were individually associated with increased odds of unstable housing after adjustment for age and sex (physical abuse AOR 1.7, 95% CI 1.2-2.5; mugging/physical attack AOR 1.8, 95% CI 1.2-2.7; sexual violence AOR 1.4, 95% CI 0.89-2.2), but were no longer significant in the fully adjusted model. Previous experiences of interpersonal violence were associated with unstable housing among Veterans. Substance use, PTSD, and other mental illness played an important role in this relationship-highlighting the potential to improve health outcomes through trauma informed approaches that address mental health, substance use, and housing concurrently.

Health Behavior Survey Among People Who Use Opioids: Protocol for Implementing Technology-Based Rapid Response Surveillance in Community Settings

BackgroundIn 2018, 2 million Americans met the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition diagnostic criteria for an opioid use disorder, and 9.9 million Americans had misused prescription pain relievers the previous year. Despite a rapid increase in opioid misuse, opioid use disorders, and overdoses, data are limited on the behavioral and contextual risks as well as the protective factors fueling the opioid epidemic in some hard hit US cities—Atlanta, Los Angeles, and Las Vegas. Opioid use also contributes to the risk of other health problems such as HIV and hepatitis C virus infections or mental health disorders and is linked to behavioral and environmental risks (eg, homelessness, experiences of violence, involvement in the justice system). Knowledge of the relationships between these linked vulnerabilities and how they influence service utilization is critical to effective policy and interventions.ObjectiveThis survey explores the relationships between demographic and economic characteristics, behavioral and environmental risk factors, and service utilization of people who use opioids to inform public health practice, policy, and future efforts to mitigate the risks faced by this population experiencing multiple health, social, and economic vulnerabilities. The results of this survey will be used to identify needs and intervention points for people who use drugs currently served by public health organizations.MethodsWe implemented a community-engaged strategy that involved development and execution of a two-stage purposive sampling plan involving selection of partner organizations (syringe exchange programs in urban settings) and recruitment and enrollment of participants aged 18-69 years served by these organizations in Atlanta, Los Angeles, and Las Vegas from 2019 to 2020. The recruited participants completed a survey, including a variety of measures to assess health (physical and mental) and health behaviors such as sexual behavior, vaccine receipt, and HIV/ hepatitis C virus infection testing. Additional items assessed drug use and misuse, syringe exchange and health service utilization, sex exchange, histories of interpersonal violence, and vaccine confidence.ResultsThis protocol was successfully implemented despite challenges such as real-time technology issues and rapidly finding and surveying a difficult-to-reach population. We sampled 1127 unique participants (248 in Atlanta, 465 in Los Angeles, and 414 in Las Vegas).ConclusionsThe establishment and utilization of strong community partnerships enabled the rapid collection of data from a typically difficult-to-reach population. Local efforts such as these are needed to develop policies and practices that promote harm reduction among people who use opioids.International Registered Report Identifier (IRRID)RR1-10.2196/25575

Assessment of Credibility of Testimony in Alleged Intimate Partner Violence: A Case Report

ABSTRACT Structured assessment of witness credibility in intimate partner violence (IPV) allegations has been well established for child custody purposes, although it is far from being systematically implemented, particularly when child custody is not at stake. Unstructured approaches may follow general, long-accepted guidelines in legal proceedings but ignore empirical knowledge about perpetrators and victims produced by years of cumulative research. Furthermore, judgments are at a high risk of being compromised by characteristics of the informant, the listener, and the situation. An accurate analysis of witness credibility is harder to accomplish and more essential when there is no conclusive evidence or when the alleged perpetrator denies the accusations and has no known history of interpersonal violence. To not believe real victims or wrongfully convict innocent individuals are miscarriages of justice that might be prevented to a certain extent if we improve credibility assessment accuracy. In this case report, I used a structured method that demonstrates how a conclusion about the credibility of an alleged victim of IPV can contrast with the conclusion produced by a trial judge. A structured credibility assessment of the alleged victim could have produced a different judgment. Implications for individuals, their families, and the justice system are discussed.

Tailoring Trauma-Sensitive Yoga for High-Risk Populations in Public-Sector Settings.

Low-income, racial-minority, high-risk populations have limited access to evidence-based treatments for posttraumatic stress disorder (PTSD), and their acceptance of complementary interventions is unknown. Trauma Center Trauma-Sensitive Yoga (TC-TSY), which has demonstrated efficacy in community samples, has not yet been widely used with ethnic minority low-income individuals. This article presents a culturally tailored version of a TC-TSY intervention delivered as a drop-in service in a public hospital-based clinic to patients with histories of interpersonal violence and suicide attempts. TC-TSY was iteratively tailored to meet the unique clinical needs of individuals within this setting. Group facilitator observations are summarized; they describe a successful initial implementation and culturally informed adaptation of the group intervention. The facilitators' observations illustrated that group members accepted the integration of this structured, gentle yoga practice into outpatient behavioral health programming and identified site-specific modifications to inform formal study. The process by which TC-TSY was adapted and implemented for Black individuals with a history of interpersonal trauma at risk for suicidal behavior can serve as a guide for tailoring other complementary, integrative interventions to meet the needs of unique clinical settings. This process is offered as a foundation for future systematic testing of this complementary, integrated, culturally adapted trauma therapy in high-risk clinical populations.

The classification of people with a history of interpersonal violence for correctional treatment purposes: Possibilities for a schema-informed approach

Abstract In a context in which there is only limited evidence to suggest that contemporary violent offender treatment results in meaningful reductions in re-conviction rates, it is important to understand the heterogeneity that exists within violent offender populations. Although a number of different typologies of interpersonally violent behavior and of those who perpetrate violence have been proposed, few have had any discernible impact on treatment programs. Based on the assumption that delivering treatment that meets the needs of these different subpopulations will improve treatment outcomes we consider how classification based on the presence of violence-related schema may hold promise in this respect.

Childhood Trauma in Persons With Schizophrenia and a History of Interpersonal Violence.

BackgroundChildhood trauma is a risk factor for psychosis as well for violent behavior and offending later in life. Childhood trauma comprises subdomains of abuse and neglect that may be differently related to later violence among patients with schizophrenia. The aim of this study was to map the subdomains of childhood trauma associated with violent offending in schizophrenia.MethodsInformation on childhood trauma from predominantly male patients with a DSM-IV diagnosis of schizophrenia and a history of violent offending (interpersonal violence) (SCZ-V, n = 19), schizophrenia patients without a history of violence (SCZ-NV, n = 34), and healthy controls (HC, n = 66) was obtained with the Childhood Trauma Questionnaire (CTQ). Differences between groups in total maltreatment scores and the five subdomains including physical, emotional, and sexual abuse, as well as physical and emotional neglect were analyzed.ResultsSCZ-V had the highest median CTQ scores for all sub-domains. SCZ-V reported significantly higher total CTQ scores than SCZ-NV and HC. SCZ-V had significantly higher scores than HC on all subdomains, and significantly higher than SCZ-NV on physical and emotional neglect. SCZ-NV had higher scores on all domains except sexual abuse compared to HC.ConclusionSCZ-V patients had higher exposure to childhood trauma than SCZ-NV, and both schizophrenia groups had higher exposure than HC. The results suggest that childhood physical and emotional neglect may be of specific importance to later violence in schizophrenia.

Posttraumatic stress disorder in urban women.

To provide an update of recent or relevant studies on posttraumatic stress disorder (PTSD) in urban women, with a special focus on biopsychosocial risk factors. Urbanization itself can increase the risk for PTSD due to the concentration of poverty, substance use and crime. Women are usually at a greater social and economic disadvantage and are victims of collective and domestic violence more often than men. Accordingly, urban women are more exposed to traumatic events that increase the prevalence of PTSD than rural women and both rural and urban men, especially those with lack of social and family protection and support (including refugees) and/or with a history of interpersonal violence. This type of events has sensitizing effects on the PTSD response to other traumatic experiences even if they are of a lesser magnitude, which may reflect women's biological susceptibility to PTSD, and could explain their higher risk of developing chronic PTSD. A complex interaction of biopsychological factors may contribute to the ultra-high-risk for PTSD among urban women. The socially modifiable factors involved highlight the importance of strategies focused on women's social development that could reduce their social suffering and its negative mental health outcomes.

Social Trust and Reciprocity Among Adolescent Girls Exposed to Interpersonal Violence.

Trauma research has traditionally focused on altered emotion regulation and its role in psychopathology, whereas mechanisms of social behavior remain comparatively unexplored, particularly among adolescents. It has been previously reported that adolescents with histories of interpersonal violence (IV) demonstrate disrupted social learning, and the degree to which they are impaired during social interactions requiring trustful behaviors may be associated with their levels of anxiety. In the present study, 52 adolescent females (n = 26 control; n = 26 IV-exposed) between ages of 11 and 17 completed a multi-round adaptation of the Trust Game in which they interacted with a confederate peer run by a computer program, alternating between the roles of investor and investee. The task was designed to operationalize the social behaviors of trust and trust reciprocity, where the magnitude of the participants' monetary investment in the confederate during the investor role represented trust while the proportion of investment returned to the confederate in the investee role represented trust reciprocity. IV-exposed and control participants did not differ in trust (i.e., as investors); however, IV-exposed participants without anxiety diagnoses demonstrated lower trust than those with anxiety diagnoses. For trust reciprocity (i.e., as investees), there were again no differences between IV-exposed participants and controls; however, IV-exposed participants with anxiety diagnoses had increased trust reciprocity compared with both other groups. Similarly, caregiver-reported anxiety symptoms were associated with trust reciprocity behaviors among the IV-exposed adolescents. Findings suggest that IV exposure and associated anxiety impacts adolescents' trust behaviors, demonstrating potential mechanisms for maladaptive social behavior among trauma-exposed youth.

Traumatic Brain Injury in Victims of Domestic Violence

ABSTRACT The article serves as the introduction to a special issue of the journal focused on traumatic brain injury in the context of domestic and intimate partner violence. The scope of the problem is enormous, where upwards of 90% of all individuals with a history of interpersonal violence have concomitant signs and symptoms of traumatic brain injury. To date, no specific assessment tools or intervention plans exist for this specific population, but draw from existing practices for athletes, soldiers, veterans, and civilians. The public health need for further investigation and collaboration drive the proposals and suggestions for best practices in specific and community-wide settings. Through awareness and education, the challenge of traumatic brain injury in domestic violence can begin to be addressed.

Gender-specific predictors of methadone treatment outcomes among African Americans at an urban clinic

Background: African American patients with opioid use disorder (OUD) have demonstrated poorer methadone maintenance treatment (MMT) outcomes compared with white patients. This issue is further complicated in urban settings, where African Americans experience high rates of poverty and publicly funded treatment. Despite interrelated factors that disadvantage African Americans, the literature focusing on this population is scant. To address this shortcoming, we conducted the first investigation of gender differences and gender-specific MMT outcome predictors among African Americans (or any racial minority population). This study provides gender-specific findings to improve African American MMT outcomes. Methods: We studied 211 African American patients (male: n = 137, 64.9%) at an urban, university-affiliated MMT clinic. We used existing intake data to assess baseline demographic, substance use, mental health, and interpersonal factors. Primary outcomes were 3-month drug+ (positive) urine drug screen (UDS) results and treatment retention. Results: Women were more likely (than men) to endorse histories of interpersonal violence, substance abuse in their social network, and mental health problems. Men reported a greater likelihood (than women) for early opioid-use onset and a lack of prior MMT. There were no gender differences in 3-month drug+ UDS or treatment retention. In multivariable analyses among women, no baseline factors predicted 3-month opioid+ UDS and physical abuse history predicted a higher proportion of 3-month cocaine+ UDS. Among men, primary injection opioid use and older age best predicted a higher proportion of 3-month cocaine+ UDS and parent substance abuse predicted shorter retention. In both gender-stratified analyses, higher proportions of 3-month opioid+ UDS and cocaine+ UDS predicted shorter retention. Conclusions: This study offers an analysis of gender differences in risk factors, MMT outcomes, and gender-specific predictors among African American patients. MMT clinics should tailor assessment and treatment protocols to address gender-specific needs.

Contagion of Violence Across the Life Course: Phenotypes of Child Maltreatment, Intimate Partner Violence and Elder Abuse in a U.S. Chinese Population

Background: Victims of interpersonal violence might have higher risks of re-experiencing violence, which has been insufficiently examined among the older populations. Even less is known about the interconnectedness among violence phenotypes in minority populations. Method: The study used cross-sectional data collected of 3,157 U.S. Chinese older adults (aged 60 or older) in Chicago to assess phenotypes (psychological, physical/sexual, financial exploitation, caregiver neglect) of child maltreatment (CM), intimate partner violence (IPV), and elder abuse (EA). Multiple logistic regression analyses were used to examine interconnectedness among these relationships. Findings: Prevalence of interpersonal violence was 11·4% for CM (physical/sexual 10·2%, psychological: 2·4%), 6·5% for IPV (psychological: 5·3%, physical/sexual: 2·8%), and 15·2% for EA (caregiver neglect: 11·2%, psychological: 9·8%, financial exploitation: 9·3%, physical/sexual: 1·2%). After adjusting for potential confounding variables, CM psychological was associated with increased risks for IPV psychological (OR 7·60, 95% CI 4·29-13·45), IPV physical/sexual (OR 4·06 CI 1·71-9·63), EA psychological (OR 3·79, 95% CI 2·20-6·51), and EA financial exploitation (OR 2·07, 95% CI 1·12-3·81). CM physical/sexual was associated with increased risks for IPV physical/sexual (OR 1·86, 95% CI 1·02-3·38), EA psychological (OR 1·70, 95% CI 1·20-2·42) and EA financial exploitation (OR 2·38, 95% CI 1·72, 3·30). IPV were associated with increased risks for all EA subtypes except for caregiver neglect. Interpretation: Professionals working with older adults should be informed that a history of interpersonal violence might further predispose one to EA. The cumulative impact of violence should also be considered when providing services or care to violence victims. Funding Statement:The authors declare: None to report.

The Corpus Callosum and PTSD Severity.

Posttraumatic stress disorder (PTSD) is a chronic, debilitating disorder that is associated with neural alterations in multiple brain regions. Neuroimaging studies have largely focused on gray matter abnormalities in PTSD, with less information known about the integrity of white matter tracts. Prior studies of brain white matter in PTSD have produced mixed results, likely due to differences in neuroimaging sequences and clinical variables. This study addressed this gap by examining the microstructural integrity of the corpus callosum, the largest white matter fiber bundle in the brain, using diffusion tensor imaging (DTI). Sixty adult females diagnosed with PTSD with a history of interpersonal violence were compared with 18 trauma-exposed controls. All participants underwent DTI using 1.5 T. MANOVA revealed significantly higher fractional anisotropy (FA; p = .012) in the genu of the corpus callosum (GCC) compared with the trauma-exposed controls. These results suggest the GCC to relate to PTSD symptomatology. Further studies of this mechanism may provide insight into improving treatment and prevention efforts.
