The impact of intuitive eating on the association between posttraumatic stress disorder (PTSD) symptoms and disordered eating among women who have experienced intimate partner violence (IPV).

OBJECTIVE: Trauma exposure is associated with disordered eating, with recent evidence suggesting PTSD symptoms may be a more proximal predictor. Intuitive eating is a well-established protective factor against disordered eating; however, no previous studies have assessed whether intuitive eating buffers the association between PTSD symptoms and disordered eating. METHODS: Two hundred sixteen women who had experienced intimate partner violence (IPV) and were residing at a domestic violence shelter completed a survey. The current study assessed the moderating role of intuitive eating in the associations between PTSD symptoms and two types of disordered eating behaviors: binge eating and compensatory behaviors. RESULTS: Intuitive eating did not moderate the association between PTSD symptoms and a dichotomous measure of binge eating (no binge eating vs. any binge eating). However, intuitive eating did moderate the association between PTSD symptoms and binge frequency, among participants endorsing any degree of binge eating, such that PTSD symptoms were significantly associated with binge frequency at low, but not moderate or high, levels of intuitive eating. Intuitive eating did not moderate the association between PTSD symptoms and compensatory behaviors. DISCUSSION: Results suggest intuitive eating may be protective against binge eating frequency among women who have experienced IPV.

'Sometimes, we don't know if we're getting abused': discussions of intimate partner violence and HIV risk among transgender women.

Transgender women are among the populations at highest risk for HIV in the USA and have elevated risk for intimate partner violence (IPV). There is an urgent need for integrated HIV-IPV prevention interventions for transgender women. Using qualitative methods, we explored transgender women's lived experiences of IPV and the relationship between IPV and HIV risk. Using thematic analysis, we identified four key concepts that warrant inclusion in the development of models for IPV and HIV interventions: (1) considering the boundaries of IPV; (2) normalising expectations of chronic violence; (3) relationship safety; (4) calls for trans-affirming and empowering services.

Impact of Surgical Status, Loneliness, and Disability on Interleukin 6, C-Reactive Protein, Cortisol, and Estrogen in Females with Symptomatic Type I Chiari Malformation.

Chiari malformation type I (CMI) provides an opportunity for examining possible moderators of allostatic load. CMI patients who had (n = 43) and had not (n = 19) undergone decompression surgery completed questionnaires regarding pain, disability, and loneliness, and provided serum samples for IL-6, CRP, estrogen, and free estradiol assays, and saliva samples to assess diurnal cortisol curves. ANOVAs examining surgical status (decompressed versus non-decompressed), loneliness (high vs. low), and disability (high vs. low) as independent variables and biomarker variables as dependent factors found that loneliness was associated with higher levels of cortisol, F(1, 37) = 4.91, p = .04, η2P = .11, and lower levels of estrogen, F(1, 36) = 7.29, p = .01, η2P = .17, but only in decompressed patients. Results highlight the possible impact of loneliness on biological stress responses and the need to intervene to reduce loneliness in patients with symptomatic CMI.

Comparing Prevalence and Correlates of Intimate Partner Sexual Victimization Relative to Other Victim-Offender Relationships in College Students.

Research on sexual victimization (SV) in college women often focuses on perpetration by nonpartners thus, little is known about SV by intimate partners on college campuses. To address this gap in the literature, the current study compared prevalence and revictimization rates and negative correlates of SV based on victim-offender relationship. Findings suggest higher prevalence rates of SV perpetrated by a nonpartner compared to an intimate partner although similar and alarming rates of revictimization. Regarding negative correlates of SV, no differences were identified based on victim-offender relationship; however, victims of SV by both an intimate partner and a nonpartner demonstrated the highest negative correlates. These findings demonstrate the importance of addressing SV by nonpartners and intimate partners and the necessity for tertiary prevention efforts to decrease revictimization.

Comparison of Adding Treatment of PTSD During and After Shelter Stay to Standard Care in Residents of Battered Women's Shelters: Results of a Randomized Clinical Trial.

This study explored the acceptability, feasibility, and initial efficacy of an expanded version of a PTSD treatment developed for residents of battered women's shelters, Helping to Overcome PTSD through Empowerment (HOPE) in women who received standard shelter services (SSSs). A Phase I randomized clinical trial comparing HOPE + SSSs (n = 30) to SSSs (n = 30) was conducted. Primary outcome measures included the Clinician-Administered PTSD Scale (Blake et al., 1995) and the Revised Conflict Tactic Scales (Straus, Hamby, Boney-McCoy, & Sugarman, ). Participants were followed at 1-week, and 3- and 6-months posttreatment. Only 2 women dropped out of HOPE + SSS treatment. Latent growth curve analyses found significant treatment effects for PTSD from intimate partner violence (IPV) (ß = -.007, p = .021), but not for future IPV (ß = .002, p = .709) across follow-up points. Significant effects were also found for secondary outcomes of depression severity (ß = -.006, p = .052), empowerment (ß = .155, p = .022), and resource gain (ß = .158, p = .036). Additionally, more women in HOPE + SSSs were employed at 3- and 6-month follow-up compared to those in SSSs only. Results showed the acceptability and feasibility of adding IPV-related treatment to standard services. They also suggested that HOPE may be a promising treatment for residents of battered women's shelters. Further research with a larger sample, utilizing more diverse shelter settings and a more rigorous control condition, is needed to confirm these findings.

Rapid HIV testing and counseling for residents in domestic violence shelters.

Over one million Americans live with the human immunodeficiency virus (HIV), and roughly 20 percent of those living with HIV are unaware of their status. One way to decrease this epidemic is community-based rapid testing with high-risk populations. One high-risk population that has received limited attention is victims of intimate partner violence who seek shelter. In an effort to gain foundational information to implement rapid HIV testing and counseling services in domestic violence shelters, the current study conducted a series of focus groups with eighteen residents and ten staff of local shelters from October 15 to December 12, 2012. Participants provided valuable insight into how HIV rapid testing and counseling might be best implemented given the resources and constraints of shelter life. Despite identifying some potential barriers, most believed that the promise of quick results, the convenience and support afforded by the shelter venue, and the timing of the intervention at a point when women are making life changes would render the intervention acceptable to residents. Further insights are discussed in the article.

Survival sex among a diverse sample of women with histories of intimate partner violence: Results from a domestic violence shelter.

OBJECTIVE: The current study sought to investigate the prevalence and correlates of survival sex among a diverse sample of women residing in a domestic violence (DV) shelter. METHOD: Two hundred seven women (44% Black, 37.7% White, 10.6% Multiracial, 4.3% Latina, 1% Arab, 1% Asian/Pacific Islander, and 1.4% Indigenous or Aboriginal) residing in a Summit County, Ohio, DV shelter completed a survey assessing their involvement in survival sex, the associated contextual factors (e.g., age at first incidence of survival sex, the reason for engaging in survival sex), and self-report measures assessing substance use, post-traumatic stress disorder (PTSD) symptoms, intimate partner violence (IPV) victimization, adverse childhood experiences (ACEs), and empowerment. RESULTS: More than two-thirds of participants reported engaging in survival sex, and participants who did were more likely to have elevated rates of substance use, PTSD symptoms, ACEs, and IPV victimization, along with lower empowerment. Most commonly, women reported engaging in survival sex for fear that the other person would take away valuable support or things they needed. Participants also reported engaging in survival sex for securing shelter, for money, for food, and to obtain drugs or alcohol. Notably, a sizable minority of women first engaged in survival sex as minors, suggesting overlap with the phenomenon of domestic minor sex trafficking. CONCLUSIONS: Engaging in survival sex may be commonly experienced by women residing in DV shelters and is associated with trauma history and post-traumatic stress symptoms. Despite the small, non-representative sample, results indicate education for providers is necessary to interact effectively with this population.

Computer-based intervention for residents of domestic violence shelters with substance use: A randomized pilot study.

BACKGROUND: Intimate Partner Violence (IPV) is a significant public health problem often associated with serious mental health and physical health implications. Substance use disorders (SUDs) are one of the most common comorbidities among women with IPV, increasing risk of subsequent IPV. METHODS: The current study examined the feasibility, acceptability, and preliminary effectiveness of a brief computerized intervention to reduce alcohol and drug use among women with IPV. Fifty women with recent IPV and alcohol and drug use risk were recruited from domestic violence shelters and randomized to the experimental computerized intervention or to an attention and time control condition. The primary outcome was percent heavy drinking or drug using days in 3 month increments over the 6 months after leaving the shelter. Receipt of substance use services and IPV severity were evaluated as secondary outcomes. RESULTS: The computerized intervention was feasible and acceptable, with high (n = 20, 80%) completion rates, engagement with the intervention, and satisfaction scores. As expected in this pilot trial, there were no significant differences between conditions in percent heavy drinking/drug using days or receipt of substance use services and large individual differences in outcomes. For example, receipt of substance use services decreased by a mean of 0.05 times/day from the baseline to the 6-month time period in the control condition (range -1.00 to +0.55) and increased by a mean of 0.06 times/day in the intervention condition (range -0.13 to +0.89). There were large decreases in IPV severity over time in both conditions, but directions of differences favored the control condition for IPV severity. CONCLUSION: A computerized intervention to reduce the risk of alcohol/drug use and subsequent IPV is feasible and acceptable among residents of a domestic violence shelter. A fully powered trial is needed to conclusively evaluate outcomes.

The Role of Race, Social Support, Empowerment, and Posttraumatic Cognitions in Survivors of Intimate Partner Violence Symptoms of Posttraumatic Stress Disorder.

Black women experience more frequent and severe intimate partner violence (IPV), but there are mixed findings on their posttraumatic stress disorder (PTSD) symptom severity. This may be explained by cultural-salient factors which are associated with fewer posttraumatic cognitions. We hypothesized an indirect effect of race on PTSD symptoms via social support, empowerment, and posttraumatic cognitions, serially. Path analysis revealed Black women reported increased social support, which was associated with higher levels of empowerment, which was associated with lower levels of posttraumatic cognitions. Decreased posttraumatic cognitions were associated with less severe PTSD symptoms. Results increase understanding of culturally-salient factors that may impact PTSD symptoms in Black women.

Associations among Intimate Partner Violence, Posttraumatic Stress Disorder Symptoms, and Disordered Eating among Women Intimate Partner Violence Survivors Residing in Shelter.

Previous research has not assessed the association between intimate partner violence (IPV) and disordered eating (DE), nor the potential indirect effect through posttraumatic stress disorder (PTSD) symptoms, among residents of IPV shelters. Among 212 IPV survivors, this study examined these and the differential associations by PTSD symptom cluster and types of DE. In the current sample, 67.9% met criteria for probable PTSD, 20.3% met criteria for a probable eating disorder, and 18.4% had probable comorbid diagnoses. Consistent with escape theory, there was an indirect effect of IPV on DE through PTSD symptoms. Additionally, there was an indirect effect of IPV on weight/shape concerns and binge symptoms through PTSD symptoms. Although there was a significant total effect of IPV on compensatory behaviors, there was no indirect effect through PTSD symptoms. When PTSD symptom clusters were examined concurrently, the only indirect effect of IPV on weight/shape concerns was via the PTSD symptom cluster of negative alterations in cognition and mood. Although there was an indirect effect of IPV on binge symptoms via PTSD symptoms overall, no specific PTSD symptom cluster drove this association. Implications highlight the need for attention to DE within this population. Consistent with escape theory, survivors' DE might serve to distract from psychological distress.

Increased stability of glycol-terminated self-assembled monolayers for long-term patterned cell culture.

Self-assembled monolayers (SAMs) are widely used to confine proteins and cells to a pattern to study cellular processes and behavior. To fully explore some of these phenomena, it is necessary to control cell growth and confinement for several weeks. Here, we present a simple method by which protein and cellular confinement to a pattern can be maintained for more than 35 days. This represents a significant increase in pattern stability compared to previous monolayer systems and is achieved using an amide-linked glycol monomer on 50 Å titanium/100 Å gold-coated glass coverslips. In addition, this study provides insight into the method of SAM degradation and excludes interfacial mixing of the monomers and blooming of the adlayer as major mechanisms for SAM degradation.

Remission of PTSD after victims of intimate partner violence leave a shelter.

Intimate partner violence (IPV) is a significant public health problem associated with high rates of posttraumatic stress disorder (PTSD). Few longitudinal studies have investigated IPV-related PTSD and we know of only 1 longitudinal study to date that has explored IPV-related PTSD in residents of battered women's shelters. The current report describes a prospective study of IPV-related PTSD in an initial sample of 147 residents of battered women's shelters. Baseline correlates of remission of IPV-related PTSD (i.e., PTSD and IPV severity, loss of personal and social resources, cessation of abuse, reunion with abuser, and length of shelter stay) over a 6-month follow-up period were investigated. Although findings are consistent with prior research suggesting a natural recovery of PTSD in IPV-victims, they also show that a significant number (46.8%) of women exhibit chronic PTSD. Participants whose PTSD remitted over follow-up had at baseline less severe IPV-related PTSD (partial η(2) = .104) and fewer loss of personal and social resources (partial η(2) = .095), and were less likely to reunite with their abuser after leaving the shelter than participants with chronic PTSD (3.3% and 22.4%, respectively). Clinical implications and limitations of findings are discussed.

Encouraging legal help seeking for victims of intimate partner violence: the therapeutic effects of the civil protection order.

Civil protective orders (CPOs) are the most widely used justice system remedy for intimate partner violence (IPV), and were implemented to ensure safety and increase victim participation in the justice system. Limited data exists regarding the effectiveness of CPOs; however, theories of therapeutic jurisprudence argue that legal interventions in and of themselves can improve mental health outcomes. To test this hypothesis, we examined the effectiveness of having a CPO issued against one's abuser at improving the psychological sequelae of exposure to trauma. We used a longitudinal sample of female residents of battered women's shelters who had experienced IPV (N = 106; 55% African American). One-way analyses of variance using gain scores indicated that PTSD symptoms (effect size η(p)(2) = .16) and incidents of sexual revictimization (effect size η(p)(2) = .09) decreased from baseline to 6-months postshelter for women who had a CPO against their most recent abuser compared to women without a CPO. These results support theories of therapeutic jurisprudence, suggesting that having a CPO can improve mental health outcomes. Limitations and clinical implications of our findings are discussed, including arguing for a coordinated service system that incorporates both legal and psychological assistance to improve the mental health of victims of IPV.

Understanding the relationship between interpersonal trauma and disordered eating: An extension of the model of psychological adaptation.

OBJECTIVE: Interpersonal trauma is a nonspecific risk factor for disordered eating (DE). Studies have begun to examine mechanisms that explain the relationship; however, few have tested comprehensive theoretical models. The Model of Psychological Adaptation (McCann, Sakheim, & Abrahamson, 1988) posits that trauma exposure results in core schema disruptions that are associated with varying psychological response patterns, or psychological adaptations, that are also established predictors of DE, such as interpersonal and affective problems. The model has been successfully applied to symptoms of other psychological disorders, such as PTSD and depression, but has not previously been extended to predict DE. The current study addressed this gap in the literature by assessing an extension of the Model of Psychological Adaptation to DE. METHOD: A sample of 371 undergraduate women completed an online survey. RESULTS: Using structural equation modeling, the results of the current study demonstrated positive fit for a model that represents the extension of the Model of Psychological Adaptation to DE. CONCLUSION: These findings corroborate the link between interpersonal trauma and DE, thus demonstrating the potential importance of assessing for DE symptoms among clients who have survived interpersonal trauma and attending to trauma history among clients who have DE. In addition, it highlights mechanisms that may be relevant to the conceptualization and treatment of DE among survivors of interpersonal trauma.

Predicting emotional abuse among a sample of college students.

Objective This study aims to examine factors related to emotional abuse, an understudied type of intimate partner violence (IPV), among a sample of college students. Participants: 601 undergraduates from one large public university in the Midwestern United States (Spring 2017) and 756 undergraduates from one large public university in the Southern United States (Fall 2019) participated in the study. Methods: Participants completed an online survey measuring demographic information, behavioral variables (viewing porn, alcohol consumption, and hooking up), and history of violence (witnessing a father abuse his spouse, emotional abuse history). Descriptive statistics and binary logistic regression analyses predicting emotional abuse victimization were conducted. Results: Results indicate female, white, older students were more likely to report emotional abuse. Also, students witnessing their father abuse his spouse, frequent pornography use, increased alcohol use, and frequent hookups increased odds of emotional abuse. Conclusion: College campuses should consider emphasizing emotional abuse in IPV programing.

The Association Between Demographic, Mental Health, and Intimate Partner Violence Victimization Variables and Undergraduate Women's Intimate Partner Violence Perpetration.

Addressing women's intimate partner violence (IPV) perpetration is essential not only to their partners' safety but also to their own as, for women who are victims of IPV, their IPV perpetration may be a risk factor for their own revictimization. Although many studies have examined risk factors for women's IPV perpetration, results diverge with regard to whether demographic and mental health variables are reliable predictors. Results of several studies have demonstrated that when IPV victimization is examined concurrently with perpetration, demographic and mental health variables are no longer significant correlates. However, this research has been limited in that the type of IPV examined has been restricted to physical, psychological, and sexual abuse. In addition, some demographic variables (e.g., sexual orientation) have yet to be adequately examined. The current study extends this literature by concurrently assessing demographic, mental health, and IPV victimization variables as correlates of IPV perpetration among undergraduate women. Furthermore, the current study examined a wide range of IPV types (i.e., threats of physical abuse, physical abuse, sexual abuse, psychological maltreatment, stalking, cyberstalking). Among a final sample of 398 undergraduate women at a Midwestern public university, results demonstrated that while all variables (i.e., demographic, mental health, IPV victimization) were correlated with at least one type of IPV perpetration, only IPV victimization remained a unique significant correlate of perpetration for each of the six IPV perpetration types when variables were analyzed concurrently in hierarchical regression models. Demographic and mental health variables were nonsignificant correlates for most IPV perpetration types. These results corroborate previous studies and provide additional evidence that targeting women's own victimization, safety planning, and de-escalation may be useful at decreasing violence against women's partners as well as women's own risk for revictimization.

Locomotor-activated neurons of the cat. II. Noradrenergic innervation and colocalization with NEα 1a or NEα 2b receptors in the thoraco-lumbar spinal cord.

Norepinephrine (NE) is a strong modulator and/or activator of spinal locomotor networks. Thus noradrenergic fibers likely contact neurons involved in generating locomotion. The aim of the present study was to investigate the noradrenergic innervation of functionally related, locomotor-activated neurons within the thoraco-lumbar spinal cord. This was accomplished by immunohistochemical colocalization of noradrenergic fibers using dopamine-ß-hydroxylase or NEα(1A) and NEα(2B) receptors with cells expressing the c-fos gene activity-dependent marker Fos. Experiments were performed on paralyzed, precollicular-postmamillary decerebrate cats, in which locomotion was induced by electrical stimulation of the mesencephalic locomotor region. The majority of Fos labeled neurons, especially abundant in laminae VII and VIII throughout the thoraco-lumbar (T13-L7) region of locomotor animals, showed close contacts with multiple noradrenergic boutons. A small percentage (10-40%) of Fos neurons in the T7-L7 segments showed colocalization with NEα(1A) receptors. In contrast, NEα(2B) receptor immunoreactivity was observed in 70-90% of Fos cells, with no obvious rostrocaudal gradient. In comparison with results obtained from our previous study on the same animals, a significantly smaller proportion of Fos labeled neurons were innervated by noradrenergic than serotonergic fibers, with significant differences observed for laminae VII and VIII in some segments. In lamina VII of the lumbar segments, the degree of monoaminergic receptor subtype/Fos colocalization examined statistically generally fell into the following order: NEα(2B) = 5-HT(2A) ≥ 5-HT(7) = 5-HT(1A) > NEα(1A). These results suggest that noradrenergic modulation of locomotion involves NEα(1A)/NEα(2B) receptors on noradrenergic-innervated locomotor-activated neurons within laminae VII and VIII of thoraco-lumbar segments. Further study of the functional role of these receptors in locomotion is warranted.

An Empirical Exploration Into the Measurement of Rape Culture.

Feminist scholars have long argued the presence of a "rape culture" within the United States; however, limited efforts have been made to quantify this construct. A model of rape culture was first proposed in 1980 and expanded in the 1990s in an effort to quantify rape myth acceptance. This model posits that five underlying components make up a rape culture: traditional gender roles, sexism, adversarial sexual beliefs, hostility toward women, and acceptance of violence. Although these components are proposed as cultural phenomenon and thus distinct from individually held beliefs, they have been exclusively explored on an individual level. Thus, to promote exploration of this phenomenon beyond individually held beliefs, the authors adapted a series of well-established measures to assess the perceived peer support of the constructs proposed to underlie rape culture and assess initial reliability and validity in a sample of 314 college students. Following determination of reliability and validity of these adapted measures, a hierarchical confirmatory factor analysis was run to examine the proposed model of rape culture. Results of this study highlight the uniqueness between individual and cultural factors as several items did not translate from an individual (i.e., personal endorsement) to a cultural level (i.e., perceived peer support) and were subsequently removed from the proposed final measurements. Furthermore, initial support for the aforementioned model of rape culture was identified. These findings are crucial given that limited conclusions may be drawn about the existence and in turn eradication of rape culture without an agreed upon definition and source of measurement.

Sexual Victimization and Disordered Eating in Bisexual Women: A Test of Objectification Theory.

The current study (a) ascertained whether there is a relationship between sexual victimization (SV) and disordered eating (DE) among bisexual women, (b) assessed whether objectification theory explains the relationship, and (c) tested for group differences between bisexual and heterosexual women on SV, DE, and other objectification theory variables. Utilizing a sample of 164 undergraduate bisexual women, there was a significant positive relationship between SV and DE that was serially mediated by self-surveillance and body shame. In addition, bisexual participants endorsed more SV, DE, body shame, and interoceptive deficits than a comparison sample of 335 undergraduate heterosexual women. Implications are discussed.

Analysis of a Modification to the Sexual Experiences Survey to Assess Intimate Partner Sexual Violence.

Greater accuracy is needed in the assessment of sexual victimization that occurs in intimate relationships. Existing assessment strategies in the literature often represent two distinct approaches - intimate partner violence specific strategies vs. sexual violence specific strategies. The current study compared multiple distinct strategies for assessing intimate partner sexual victimization (IPSV) and evaluated a modification that optimizes intimate partner and sexual violence specific strategies. Two samples of undergraduate women were recruited. Sample 1 (N = 236) completed the Severity of Violence Against Women Scales (SVAWS) and a modified version Sexual Experiences Survey-Short Form Victimization (SES-SFV) in which participants were cued to respond both for romantic partners and non-partners (referred to as the SES-RP/NP). Sample 2 (N = 206) completed the SVAWS and was randomized to either the traditional SES-SFV or the SES-RP/NP. Across samples, the prevalence of IPSV varied based on the measure used (SVAWS = 11.7%; SES-SFV = 17.0%; SES-RP/NP = 25.4%). The SES-RP/NP identified significantly more IPSV than the SES-SFV, SVAWS, and prior studies. Both the SES-SFV and the SES-RP/NP were positively and significantly associated with the SVAWS. The results suggested that optimal measurement of IPSV would consider both intimate partner and sexual violence strategies.
