Posttraumatic survivor guilt is associated with white matter microstructure alterations.

BACKGROUND: Military veterans with posttraumatic stress disorder (PTSD) commonly experience posttraumatic guilt. Guilt over commission or omission evolves when responsibility is assumed for an unfortunate outcome (e.g., the death of a fellow combatant). Survivor guilt is a state of intense emotional distress experienced by the weight of knowing that one survived while others did not. METHODS: This study of the Translational Research Center for TBI and Stress Disorders (TRACTS) analyzed structural and diffusion-weighted magnetic resonance imaging data from 132 male Iraq/Afghanistan veterans with PTSD. The Clinician-Administered PTSD Scale for DSM-IV (CAPS-IV) was employed to classify guilt. Thirty (22.7 %) veterans experienced guilt over acts of commission or omission, 34 (25.8 %) experienced survivor guilt, and 68 (51.5 %) had no posttraumatic guilt. White matter microstructure (fractional anisotropy, FA), cortical thickness, and cortical volume were compared between veterans with guilt over acts of commission or omission, veterans with survivor guilt, and veterans without guilt. RESULTS: Veterans with survivor guilt had significantly lower white matter FA compared to veterans who did not experience guilt (p < .001), affecting several regions of major white matter fiber bundles. There were no significant differences in white matter FA, cortical thickness, or volumes between veterans with guilt over acts of commission or omission and veterans without guilt (p > .050). LIMITATIONS: This cross-sectional study with exclusively male veterans precludes inferences of causality between the studied variables and generalizability to the larger veteran population that includes women. CONCLUSION: Survivor guilt may be a particularly impactful form of posttraumatic guilt that requires specific treatment efforts targeting brain health.

Intimate Partner Violence-Related Brain Injury: Unmasking and Addressing the Gaps.

Intimate partner violence (IPV) is a significant, global public health concern. Women, individuals with historically underrepresented identities, and disabilities are at high risk for IPV and tend to experience severe injuries. There has been growing concern about the risk of exposure to IPV-related head trauma, resulting in IPV-related brain injury (IPV-BI), and its health consequences. Past work suggests that a significant proportion of women exposed to IPV experience IPV-BI, likely representing a distinct phenotype compared with BI of other etiologies. An IPV-BI often co-occurs with psychological trauma and mental health complaints, leading to unique issues related to identifying, prognosticating, and managing IPV-BI outcomes. The goal of this review is to identify important gaps in research and clinical practice in IPV-BI and suggest potential solutions to address them. We summarize IPV research in five key priority areas: (1) unique considerations for IPV-BI study design; (2) understanding non-fatal strangulation as a form of BI; (3) identifying objective biomarkers of IPV-BI; (4) consideration of the chronicity, cumulative and late effects of IPV-BI; and (5) BI as a risk factor for IPV engagement. Our review concludes with a call to action to help investigators develop ecologically valid research studies addressing the identified clinical-research knowledge gaps and strategies to improve care in individuals exposed to IPV-BI. By reducing the current gaps and answering these calls to action, we will approach IPV-BI in a trauma-informed manner, ultimately improving outcomes and quality of life for those impacted by IPV-BI.

PTSD Symptom Cluster Severity Predicts Momentary Emotion Dynamics During Couple Conversations.

This study investigated the associations between momentary emotion dynamics and posttraumatic stress disorder (PTSD) symptoms. Using a sample of 61 couples (N = 122 individuals) in which all individuals were trauma exposed and at least one partner screened positive for PTSD, we examined the intra- and interpersonal regulation of vocally encoded emotional arousal (fundamental frequency [f0]) and how these momentary emotion regulatory patterns relate to specific PTSD symptoms during two couple conversations: one designed to elicit conflict and one to elicit intimacy. PTSD symptoms were assessed using a gold standard clinical interview. In both conversations, higher reexperiencing symptoms were associated with greater emotional inertia (i.e., more resistance to change in emotional state following deviation from one's emotional equilibrium), and higher avoidance symptoms were associated with less emotional inertia (i.e., quicker return to emotional equilibrium). In the intimacy conversations, individuals also responded to their partners' arousal. Furthermore, individuals whose partners exhibited higher emotional numbing symptoms exhibited more emotional inertia, suggesting that emotion regulation may be a function of both one's own and one's partner's PTSD symptoms. Attending to the interpersonal context of emotion dynamics during PTSD treatment may enhance outcomes.

Development and validation of the Moral Outcomes of Relationship Aggression Scale: A measure of moral distress following intimate partner violence perpetration.

Research with military veterans has established that distress may arise in response to perpetrating violent behaviors that violate individuals' moral beliefs. To date, no studies have similarly examined morally-related cognitive and emotional responses specifically among intimate partner violence (IPV) perpetrators. However, research on moral cognitions and emotions in response to IPV perpetration may inform understanding of the behavior and potential mechanisms for intervention. In the current series of four studies, we used classical test theory to develop a measure of moral distress following IPV perpetration that focuses on thoughts about the actions (assimilated cognitions), thoughts about the self due to one's actions (accommodated cognitions), and emotions experienced due to one's actions (moral emotions). Items were developed and tested among two samples of undergraduate students, and psychometric properties of the final measure were confirmed among two community samples. The final measure consists of three subscales consisting of five items each. Results demonstrate support for internal consistency and test-retest reliability, convergent, discriminant, and incremental validity, and factor structure. This measure can be used in future research designed to examine how individuals respond to their IPV perpetration, and to study the implications this may have for long-term outcomes and behavioral change.

Responsivity to Interviewer during Interview-Based Assessment of Physical Intimate Partner Violence.

Objective: Interview assessments of intimate partner violence (IPV) may provide more accurate behavior frequency estimates than self-report questionnaires. However, concerns have been raised about whether participants underreport IPV during interviews due to an emotional response to the interviewer. Method: Participants were 42 mixed gender community couples (83 individuals) in which at least one partner endorsed physical IPV perpetration or victimization in their relationship. We examined whether participants were emotionally responsive to the interviewer during an interview about physical IPV. Responsivity was defined as the extent to which participants' emotional arousal, indexed by vocal fundamental frequency (f0), was predicted by interviewers' emotional arousal at the previous talk turn on a moment-by-moment basis. We then examined whether participants' responsivity predicted interview-based reporting of IPV relative to their own self-report on an IPV measure and to the highest other available report (including partner report). Results: Repeated measures actor-partner interdependence models conducted in a multi-level modeling framework indicated that, on average, participants were responsive to interviewers' emotional arousal, even when controlling for responsivity to their own arousal, and that responsivity varied across participants. However, participants' responsivity to interviewer arousal did not significantly predict reporting of IPV perpetration or victimization during the interview relative to their own self-report or to the highest other available report. Conclusions: Participants are emotionally responsive to interviewer arousal, but this responsivity does not appear to reduce interview-based reporting of IPV relative to self-report, supporting the utility of IPV interviews in clinical and research settings.

In vivo defensive behaviors, fear, and attention bias to physical and negative evaluation threats.

Aggressive behavior is a major public health issue for which there are few efficacious treatments. Although much of information processing is automatic, there are few studies of early-stage decoding biases (e.g., attention bias to threat) and aggressive behavior, potentially resulting in missed opportunities for identifying targets of intervention. Previous studies are limited by indirect measures of attention bias and little consideration of proximal factors like state fear, which organizes perception and motivates defensive behaviors. We used laboratory methods (i.e., eye-tracking, idiographic mood induction, and the Point Subtraction Aggression Paradigm), to examine the association between attention bias to physical and negative evaluation threat and in vivo defensive responding (i.e., aggression and escape) and the potential moderating role of state fear among 74 undergraduate students. As predicted, attention bias to threat was positively associated with in vivo aggression. Fear did not potentiate aggression or modify the relationship between attentional bias to threat and aggression; however, in the fear condition, greater attentional bias to threat was associated with less escape behavior. Findings add to the sparse literature identifying early-stage decoding processes as possible risk factors of aggression and suggest a need for additional research on freeze behavior in response to threat and provocation.

Parent-to-child aggression, intimate partner aggression, conflict resolution, and children's social-emotional competence in early childhood.

Early childhood is critical to the development of children's social-emotional competence, which predicts peer relations and school adjustment in later periods of childhood. The effects of experiencing or witnessing aggression on children's social-emotional development are well known, yet the role of conflict resolution within the family has not been sufficiently studied. Social information processing models suggests that children who experience positive forms of conflict resolution within the family are likely to generalize these experiences and related skills outside the family, and thus develop greater social-emotional competence. In this longitudinal study, 128 parents (representing 79 families) participated in four quarterly telephone interviews in which they described aggressive conflicts that occurred in their family for which their children were present, including the degree to which each conflict was resolved. They also reported on the frequency of intimate partner aggression (IPA) and parent-to-child aggression (PCA) that occurred while the child was in toddlerhood and preschool as well as children's social-emotional competence at the end of the study. Multi-level models reveal that parents' reports of positive conflict resolution mitigated the concurrent and longitudinal negative effects of children's exposure to both IPA and PCA on their social-emotional competence. These findings reinforce prevention scientists' emphasis on conflict resolution skills as an essential component of parent education programs.

La primera infancia es fundamental para el desarrollo de la competencia socioemocional de los niños, la cual predice las relaciones entre pares y la adaptación escolar en periodos posteriores de la niñez. Se conocen muy bien los efectos que producen el sufrir o ser testigos de agresión en el desarrollo socioemocional de los niños, sin embargo, aún no se ha estudiado de manera suficiente el papel que desempeña la resolución de conflictos dentro de la familia. Los modelos de procesamiento de la información social sugieren que los niños que viven formas positivas de resolución de conflictos dentro de la familia son propensos a generalizar estas experiencias y las habilidades afines fuera de la familia y, por lo tanto, a desarrollar una mayor competencia socioemocional. En este estudio longitudinal, 128 padres (que representaban 79 familias) participaron en cuatro entrevistas telefónicas cada tres meses en las cuales describieron conflictos agresivos que hubo en su familia en los cuales sus hijos estuvieron presentes, incluido el grado en el cual se resolvió cada conflicto. También informaron la frecuencia de agresión en la pareja y de agresión de padres a hijos que tuvo lugar durante sus primeros años de vida y en la etapa del preescolar, así como la competencia socioemocional de los niños al final del estudio. Los modelos multinivel indican que los informes de los padres sobre la resolución positiva de los conflictos mitigaron los efectos negativos longitudinales y simultáneos de la exposición de los niños a la agresión en la pareja y a la agresión de padres a hijos en su competencia socioemocional. Estos resultados refuerzan el énfasis en las habilidades de resolución de conflictos de los científicos de la prevención como componente esencial de los programas de educación para padres.

Relational impacts of capitalization in early parenthood.

Relationship difficulties are common during the transition to parenthood and may persist for years. Strategies that enhance couples' daily relational experiences early in the parenting years may serve a protective role. In general, engaging in a capitalization attempt (i.e., sharing personal good news) with one's romantic partner and perceiving the partner to be responsive are associated with better relationship outcomes among committed couples. However, it is unknown whether these relational benefits extend to the early parenting years or to other relational domains such as coparenting, which plays a central role in family functioning. The current study examined same-day associations between couples' capitalization process and relationship closeness and perceived coparenting support in a dyadic context during the first year of parenthood. A subsample of primarily non-Hispanic White coresident mixed-gender couples who participated in a randomized controlled trial of a transition to parenthood program (N = 141) completed daily diaries at 10 months postpartum for 8 consecutive days. On days when mothers shared, both partners reported greater closeness. On days when fathers shared, mothers reported greater closeness and perceived coparenting support. Furthermore, perceived partner responsiveness was associated with greater closeness for both partners and greater coparenting support for fathers. Fathers also perceived greater closeness and coparenting support on days when mothers shared about the child. Findings highlight the potential benefits of capitalization in early parenthood for both closeness and perceived coparenting support and suggest that capitalization may be a low cost, high yield strategy for enhancing new parents' daily relational experiences.

Intimate partner violence, substance use, and health comorbidities among women: A narrative review.

Exposure to intimate partner violence (IPV), including physical, sexual, and psychological violence, aggression, and/or stalking, impacts overall health and can have lasting mental and physical health consequences. Substance misuse is common among individuals exposed to IPV, and IPV-exposed women (IPV-EW) are at-risk for transitioning from substance misuse to substance use disorder (SUD) and demonstrate greater SUD symptom severity; this too can have lasting mental and physical health consequences. Moreover, brain injury is highly prevalent in IPV-EW and is also associated with risk of substance misuse and SUD. Substance misuse, mental health diagnoses, and brain injury, which are highly comorbid, can increase risk of revictimization. Determining the interaction between these factors on the health outcomes and quality of life of IPV-EW remains a critical need. This narrative review uses a multidisciplinary perspective to foster further discussion and research in this area by examining how substance use patterns can cloud identification of and treatment for brain injury and IPV. We draw on past research and the knowledge of our multidisciplinary team of researchers to provide recommendations to facilitate access to resources and treatment strategies and highlight intervention strategies capable of addressing the varied and complex needs of IPV-EW.

Trauma during Early Adolescence and Boys' Social Behavior: A Focus on Teen Dating Violence.

Although early adolescence is increasingly recognized as commencing a sensitive period for social development, little research exists on the impact of trauma exposure during this juncture. We hypothesized that trauma experienced during early adolescence would be particularly disruptive to the acquisition of social skills necessary for healthy future relationships. Among 1500 boys from the National Comorbidity Study Adolescent Supplement, we examined trauma exposure across developmental periods on interpersonal outcomes in late adolescence. Most (62.3%) participants reported prior exposure to at least one potentially traumatic event, and rates of such exposures generally increased linearly over time with a relative spike in exposure occurring at age 15. Trauma exposure during early adolescence, but not other developmental periods, uniquely predicted boys' perpetration of physical teen dating violence (TDV; OR = 2.2) and broader social problems (B = 2.061, SE = .091) in late adolescence. In contrast, and consistent with existing literature, trauma exposure early in development and during mid-adolescence predicted late adolescence conduct disorder diagnoses. At least in the context of early adolescent exposure, the link between trauma and TDV perpetration may be conceptualized within a broader framework of social competence rather than oft-purported antisociality. Early adolescence may present opportunities for targeted prevention of TDV and broader social problems.

Intimate Partner Aggression During the Early Parenting Years: The Role of Dissatisfaction with Division of Labor and Childcare.

The high rates of intimate partner aggression (IPA) among new parents may be partly due to changes in couples' division of household labor and childcare, which disproportionately negatively impact women. This is the first study to examine the association between division of labor dissatisfaction and IPA perpetration across genders, while also examining whether such dissatisfaction is specifically associated with IPA during conflicts about division of labor issues. Quarterly for one year, 109 women and 94 men from 111 couples with a first-born child approximately 32 months of age at study commencement described each incident of IPA that occurred during the quarter, including conflict topics and number of aggressive acts perpetrated. Division of labor and childcare comprised the largest portion (30%) of IPA conflict topics. Division of labor dissatisfaction at child age 24 months was positively associated with women's, but not men's, IPA perpetration during conflicts about division of labor issues, but not other topics. A similar pattern of results emerged in the examination of division of childcare dissatisfaction and conflicts about childcare vs. other topics. The discovery that the impact of division of labor and childcare dissatisfaction on IPA perpetration is context- and gender-specific suggests that, among women, a history of dissatisfaction may impair appropriate conflict resolution skills specifically when addressing domains of dissatisfaction. These findings support prevention of women's IPA via nonaggressive strategies for addressing division of labor concerns and promotion of equal opportunities for women and men at home and in the workplace during the early parenting years.

A global collaboration to study intimate partner violence-related head trauma: The ENIGMA consortium IPV working group.

Intimate partner violence includes psychological aggression, physical violence, sexual violence, and stalking from a current or former intimate partner. Past research suggests that exposure to intimate partner violence can impact cognitive and psychological functioning, as well as neurological outcomes. These seem to be compounded in those who suffer a brain injury as a result of trauma to the head, neck or body due to physical and/or sexual violence. However, our understanding of the neurobehavioral and neurobiological effects of head trauma in this population is limited due to factors including difficulty in accessing/recruiting participants, heterogeneity of samples, and premorbid and comorbid factors that impact outcomes. Thus, the goal of the Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Consortium Intimate Partner Violence Working Group is to develop a global collaboration that includes researchers, clinicians, and other key community stakeholders. Participation in the working group can include collecting harmonized data, providing data for meta- and mega-analysis across sites, or stakeholder insight on key clinical research questions, promoting safety, participant recruitment and referral to support services. Further, to facilitate the mega-analysis of data across sites within the working group, we provide suggestions for behavioral surveys, cognitive tests, neuroimaging parameters, and genetics that could be used by investigators in the early stages of study design. We anticipate that the harmonization of measures across sites within the working group prior to data collection could increase the statistical power in characterizing how intimate partner violence-related head trauma impacts long-term physical, cognitive, and psychological health.

Concordance of Reports of Intimate Partner Violence Across Partners and Measures: The Impact of Posttraumatic Stress Disorder.

The Revised Conflict Tactics Scales (CTS2) is frequently used to assess intimate partner violence (IPV), but consistently yields low to moderate interpartner concordance of reports. Interpartner concordance on an alternative measure, the Event History Calendar Interview (EHCI), is largely unknown. We observed limited interpartner concordance of IPV reports on the CTS2 and EHCI, with wives generally reporting more IPV than husbands. Compared with the CTS2, the EHCI detected more cases of IPV, but not differential behavior counts. Partners' posttraumatic stress disorder severity, a common respondent characteristic and focus of IPV research, was associated with low interpartner concordance of reports on the CTS2, but not the EHCI. Additionally, husbands' posttraumatic stress disorder severity was associated with wives reporting more husband-perpetrated IPV on the CTS2 than the EHCI. Overall, the EHCI appears to mitigate some of the problems associated with the CTS2 as a measure of IPV, particularly among more highly traumatized samples.

Ctcf haploinsufficiency mediates intron retention in a tissue-specific manner.

CTCF is a master regulator of gene transcription and chromatin organisation with occupancy at thousands of DNA target sites genome-wide. While CTCF is essential for cell survival, CTCF haploinsufficiency is associated with tumour development and hypermethylation. Increasing evidence demonstrates CTCF as a key player in several mechanisms regulating alternative splicing (AS), however, the genome-wide impact of Ctcf dosage on AS has not been investigated. We examined the effect of Ctcf haploinsufficiency on gene expression and AS in five tissues from Ctcf hemizygous (Ctcf+/-) mice. Reduced Ctcf levels caused distinct tissue-specific differences in gene expression and AS in all tissues. An increase in intron retention (IR) was observed in Ctcf+/- liver and kidney. In liver, this specifically impacted genes associated with cytoskeletal organisation, splicing and metabolism. Strikingly, most differentially retained introns were short, with a high GC content and enriched in Ctcf binding sites in their proximal upstream genomic region. This study provides new insights into the effects of CTCF haploinsufficiency on organ transcriptomes and the role of CTCF in AS regulation.

Prospective, dyadic links between posttraumatic stress disorder symptoms and family violence in the early years of parenthood.

Cross-sectional research has suggested that posttraumatic stress disorder (PTSD) symptom severity may be an important predictor of family violence perpetration; however, causal inference is limited by the absence of studies designed to prospectively predict family violence by PTSD symptoms. In the current study, PTSD symptoms were assessed among 250 trauma-exposed heterosexual couples 10 months after having their 1st child. The number of acts of psychological and physical intimate partner aggression (IPA) and parent-to-child aggression (PCA) that occurred during the past year was assessed at 10 and 24 months postpartum to account for stability in family violence perpetration when prospectively predicting perpetration. Longitudinal actor-partner interdependence models revealed that women's and men's PTSD symptoms positively predicted increases in the frequency of their own perpetration of psychological and physical IPA as well as psychological PCA. Additionally, partners' PTSD symptoms prospectively predicted psychological and physical IPA perpetration but not psychological or physical PCA perpetration, suggesting that partners' PTSD symptoms may directly impact dyadic processes during incidents of IPA but may not generally affect the family environment in a way that potentiates all forms of aggression. No significant gender differences were revealed. Overall, results of the current study largely support existing research and theory while clarifying inconsistencies that have emerged when examining cross-sectional associations. Further, the current results highlight the potential utility of PTSD treatment as an avenue for aggression prevention and intervention efforts during the early parenting years.

The impact of negative attributions on the link between observed partner social support and posttraumatic stress disorder symptom severity.

Lack of perceived social support is one of the strongest correlates of the development and maintenance of posttraumatic stress disorder (PTSD). However, little is known about observed social support and PTSD. The stress buffering effect of social support may be partly determined by the subjective experience of support, which is created by attributions regarding support behaviors. We examined negative attributions about partner-provided support as a moderator of the expected relation between observed support during couple discussions and PTSD symptom severity. Participants included 128 individuals from 64 heterosexual married or cohabitating couples. Per clinician-administered interview, 72 (56%) participants met subthreshold or diagnostic criteria for PTSD. Receipt of relatively more partner support was modestly associated with lower PTSD symptom severity. Negative causal attributions about partner support were not associated with the amount of support received, but were associated with higher PTSD severity. Additionally, the frequency and quality of received partner support was associated with lower PTSD symptom severity only among those who did not make strong negative causal attributions about partner support. Thus, negative causal attributions may dampen the positive effects of social support on PTSD symptoms. PTSD treatments may more effectively facilitate recovery from trauma by decreasing negative support attributions.

Children's emotional and behavioral reactions to interparental aggression: The role of exposure to within-incident, cross-dyad aggression spillover.

Despite children's frequent exposure to psychological and physical intimate partner aggression (IPA) and associated long-term consequences, little is known about children's immediate, within-incident reactions to IPA. Additionally, differences in reactions to IPA based on exposure to within-incident "spillover" of aggression across interparental and parent-child dyads have previously remained unexamined. Parents of children age 2.5 years at study commencement (N = 203 from 111 families) reported on incidents of family aggression four times for 1 year. Among select IPA incidents with the child present (n = 163 incidents from 73 families), IPA severity and children's exposure to aggression spillover were uniquely associated with children's expression of greater fear. Moreover, children unexposed to spillover experienced high fear only during relatively severe IPA incidents, whereas spillover-exposed children experienced high fear regardless of IPA severity (supporting observations of fear reactivity in response to low-level threats). Additionally, IPA severity positively predicted, and spillover exposure negatively predicted, children's attempts to make peace or solve the problem for their parents. Further, spillover-exposed children were more likely to withdraw or attempt to make peace during relatively more severe incidents of IPA. Thus, spillover-exposed children may manage their fear during relatively severe IPA incidents by withdrawing and/or engaging in active peacemaking behaviors but not by using other methods that may increase risk of aggression turning toward them. These results extend existing research, illustrate the unique predictive value of within-incident aggression spillover, and provide a foundation for understanding mechanisms through which IPA affects children in a diversity of ways.

Parents' PTSD symptoms and child abuse potential during the perinatal period: Direct associations and mediation via relationship conflict.

BACKGROUND: Posttraumatic stress disorder (PTSD) symptoms are associated with parental aggression towards children, but little is known about the relation between parents' PTSD symptoms and their risk for perpetrating child physical abuse during the early parenting years, when the potential for prevention of abuse may be highest. OBJECTIVE: To examine direct associations between mothers' and fathers' PTSD symptoms and child abuse potential, as well as indirect effects through couple relationship adjustment (i.e., conflict and love) in a high-risk sample of parents during the perinatal period, most of whom were first-time parents. PARTICIPANTS AND SETTING: From March 2013 to August 2016, data were collected from 150 expecting or new parental dyads in which the mother was participating in a home visiting program. METHODS: Data were analyzed using the Actor-Partner Interdependence Mediation Model. RESULTS: For mothers and fathers, there were direct associations between PTSD symptom severity and child abuse potential (ßs = .51, ps <.001), and this association for fathers was stronger at higher levels of mothers' PTSD symptoms (ß = .15, p = .03). In addition, parents' own and their partners' PTSD symptoms were each indirectly associated with parents' own child abuse potential through parents' report of interparental conflict (standardized indirect effects = .052-.069, ps = .004) but not love. CONCLUSIONS: Addressing parents' PTSD symptoms and relationship conflict during the perinatal period using both systemic and developmental perspectives may uniquely serve to decrease the risk of child physical abuse and its myriad adverse consequences.

Interpersonal relationship quality mediates the association between military-related posttraumatic stress and academic dysfunction among student veterans.

OBJECTIVE: Large numbers of United States service members and veterans are enrolling in colleges and universities. Many are experiencing posttraumatic stress symptoms secondary to their military service, and these symptoms are associated with academic dysfunction. However, little is known about the mechanism(s) through which posttraumatic stress increases risk for academic difficulties. The goal of the current study was to evaluate perceived interpersonal relationship quality as a mediator of this association. METHOD: The current study investigated the indirect effect of posttraumatic stress on academic dysfunction through three indices of perceived interpersonal relationship quality (i.e., family distress, family support, and social network support) in a clinical sample of 2,120 student service members and veterans. Participants were further divided into four groups based on relationship status and gender (i.e., partnered women, nonpartnered women, partnered men, and nonpartnered men), and moderation by group was examined. RESULTS: For all four groups, there were significant indirect effects of posttraumatic stress on academic dysfunction through greater family distress and lower social network support. Further, the overall indirect effect of posttraumatic stress on academic dysfunction was stronger for partnered women compared with the three other groups and was attributable to the stronger path from family distress to academic dysfunction for partnered women. CONCLUSIONS: Poor perceived relationship quality may be a modifiable risk factor for academic dysfunction among student service members and veterans experiencing military-related posttraumatic stress. Partnered women may be especially well-suited to interventions that enhance the interpersonal context of posttraumatic stress as a way to optimize academic outcomes.

Observed Emotional Expressivity, Posttraumatic Stress Disorder Symptoms, and Intimate Partner Violence Perpetration Among Community Couples.

Impaired emotional processes are related to posttraumatic stress disorder (PTSD) and are implicated in intimate partner violence (IPV) perpetration. To address the interpersonal context of PTSD, emotion, and IPV, we examined interactions among one's own and one's partner's emotional expressivity and PTSD symptom severity in association with IPV perpetration. Heterosexual couples (N = 56) in which at least one partner met screening criteria for PTSD engaged in two video-recorded discussions about negative and positive aspects of their relationships. Videos were coded for observed emotional expressiveness during moments participants reported experiencing significant emotions. Actor-partner interdependence models revealed few main effects of emotional expressivity, except that women's expressivity of positive emotions was positively associated with men's IPV perpetration, r2adj = .14. Emotional expressivity played a larger role among couples managing PTSD symptoms; that is, the association between one's own PTSD symptom severity and more IPV perpetration was stronger among men who expressed more negative emotions, r2adj = .19, and women who expressed fewer negative emotions, r2adj = .21. Several partner effects suggested the importance of understanding the dyadic nature of these constructs. For example, men's PTSD symptom severity was differentially associated with each partners' IPV perpetration based on women's expressivity of positive emotion, r2adj = .22-.27. Understanding of emotional expressivity in the link between PTSD and IPV must include consideration of gender differences in how these constructs operate interpersonally. Strategies to promote moderate and safe communication of positive and negative emotions may prevent IPV escalation, particularly among couples managing PTSD symptoms.
