The interplay between interpersonal stress and psychological intimate partner violence over time for young at-risk couples

Parental relationship satisfaction, symptoms of depression and anger/hostility, and the moderating role of perceived social support-a prospective cohort study in the light of the COVID-19 pandemic

Background

The challenging early parenthood time and the strains of the COVID-19 pandemic negatively affected parental mental health, whereas relationship satisfaction and perceived social support acted protective. Previous research focused on mothers, and little is known about mental health factors besides depression. This study aimed to investigate how relationship satisfaction and perceived social support affected symptoms of depression and anger/hostility in mothers and fathers in the light of the COVID-19 pandemic and whether perceived social support moderated these associations.

Methods

n = 1,414 mothers and n = 885 fathers participating in the prospective cohort DREAM study completed questionnaires 14 months and 2 years postpartum. Hierarchical moderated regression analyses were conducted, controlling for the phase in the COVID-19 pandemic (before, during lockdown, during easements, afterwards) during which mental health was assessed.

Results

Greater relationship satisfaction and perceived social support 14 months postpartum predicted fewer symptoms of depression and anger/hostility 2 years postpartum. Greater perceived social support moderated the association between relationship satisfaction and paternal symptoms of anger/hostility. Mental health symptoms were not significantly associated with the COVID-19 pandemic.

Limitations

Limitations concern the limited representation of the post-pandemic group and the undifferentiated measurement of social support sources.

Conclusion

The importance of relationship satisfaction and perceived social support for parental mental health is highlighted. Perceived social support can enhance the protective effect relationship satisfaction has on paternal symptoms of anger/hostility. Implementing corresponding prevention and education classes could improve parental mental health.

Did the COVID-19 pandemic increase intimate partner aggression among married couples?

Discrepant theoretical perspectives assert that challenges brought on by COVID-19 could either increase or decrease intimate partner aggression (IPA) between spouses. As reliance on retrospective or post-COVID-19 data cannot resolve these competing views, we turn to a sample of established mixed-sex married couples (N = 223) who provided six waves of pre-COVID-19 data and three waves of post-COVID-19 data. We examined whether the onset of COVID-19 affected IPA and whether any such changes were more pronounced for some couples than for others. Replicating prior research, dyadic piecewise regression showed that IPA declined significantly over time prior to COVID-19; these declines continued following the onset of the COVID-19 pandemic. Post-COVID-19 IPA intercepts were reliably lower than pre-COVID-19 intercepts, and the proportion of couples reporting any IPA dropped by 20% after the pandemic onset. Finally, post-COVID-19 IPA intercepts tended to be higher when, prior to the onset of COVID-19, spouses reported more IPA, less relationship satisfaction, and more stress, suggesting continuity rather than disruption in predictors of IPA. Thus, on average, among established mixed-sex married couples, (a) IPA declined over time, including from before to after COVID-19 onset, and (b) post-COVID-19 levels of IPA were predictable from pre-COVID-19 couple functioning.

Relationship dynamics associated with emotional IPV perpetration and victimization: A meta-analysis

Emotional intimate partner violence (IPV) is the most common form of IPV and frequently co-occurs with other forms of IPV. Risk factors of IPV can give insight to potential pathways and consequences associated with IPV, enhancing treatment efforts. This meta-analysis examined relationship dynamics associated with IPV perpetration and victimization. Our study found victimization of controlling behavior, demand/withdrawal relationship pattern, perpetration of controlling behavior, jealousy, relationship distress, perpetrator's power in the relationship, anxious attachment, and traditional gender roles were all significantly associated with IPV perpetration. For IPV victimization, victimization of controlling behaviors, fear of the perpetrator, relationship distress, anxious and avoidant attachment, and traditional gender roles were all found to be significantly associated. Relationship satisfaction was found to be negatively associated with emotional IPV perpetration and victimization. Implications for clinicians are discussed.

Partner Gender and Binegativity Uniquely Impact Relationship Quality among Bisexual Men

Romantic relationships both buffer and exacerbate adverse health outcomes among bisexual individuals, so understanding determinants of their functioning may be key to correcting health inequities affecting this population. Binegativity (i.e., prejudiced attitudes about bisexuality) expressed from one's intimate partner has the potential to be uniquely impactful for bisexuals, but it is presently unknown how this experience might impact the quality (and therefore potential health promotive effects) of their romantic relationships. In addition, gender of one's current romantic partner may shape experiences of binegativity and relationship quality in important ways. The purpose of this report was to examine how binegativity from intimate partners impacts relationship functioning (i.e., relationship satisfaction and intimate partner aggression) among bisexual men (N = 113), and how the gender of one's partner might moderate this effect. Results suggested that binegativity is detrimentally associated with relationship satisfaction, and that bisexual men in relationships with women report more frequent intimate partner aggression. Furthermore, partner gender and binegativity showed novel interactive associations with intimate partner aggression, such that bisexual men in relationships with women tended to perpetrate less intimate partner aggression when experiencing more binegativity. These results are discussed with regard to future avenues for research into the health promotive benefits of relationships for bisexual individuals.

Longitudinal Association Between Intimate Partner Violence and Alcohol Use in a Population Cohort of South African Women

Intimate partner violence (IPV) is a common traumatic stressor for women worldwide, especially for women living in low-and-middle-income countries. One of the most common correlates of IPV victimization is alcohol use, but the dynamics of IPV and drinking among women are not well understood. Although some research suggests that women drink in the aftermath of IPV to cope with distress related to the violence they experienced, other studies imply that higher levels of alcohol use among one or both partners in a relationship make violence more likely. In this study, we examine this question in a secondary analysis of a longitudinal study of a population cohort of pregnant women in South Africa (N = 1238) using a Bayesian approach to latent growth curve structural equation modeling. Results indicate that on average, IPV decreases and alcohol use increases over time and that these trajectories are associated with each other. Further, results suggest that although IPV drives drinking (rather than the other way around), higher average levels of alcohol use are associated with a slower decrease in IPV. Findings have implications for future research on the association between IPV and alcohol use, as well as for clinical intervention for women who experienced IPV.

Unique Effects of Psychological Distress in Victimization and Perpetration of Intimate Partner Violence

Introduction: Intimate partner violence (IPV) reliably co-occurs with psychological distress. However, understanding the precise nature of the association between these two classes of variables, as potential cause or effect, is complicated by the fact that victimization of IPV is not often studied controlling for simultaneous perpetration, and vice versa. It is therefore important to control for one form of IPV when testing predictors of the other to accurately understand the extent to which psychological distress may predispose people to these serious interpersonal problems. Method: Two national survey studies were conducted to test the unique associations between victimization and perpetration of IPV with psychological distress. In the first study, 773 adults completed survey measures of IPV (victimization and perpetration) and psychological distress (depression and stress). In the second study, 389 participants completed the same measures as in Study 1, but at two waves separated by three months (T1-T2 follow-up rate 73%). Results: In study 1, both depression and stress were concurrently associated with perpetrating IPV, when controlling for victimization. However, only depression was associated with victimization, after controlling for perpetration. Results of study 2 showed that both depression and stress are prospectively associated with IPV victimization. However, they are not prospectively associated with IPV perpetration, net the effect of IPV victimization. Discussion: These results are consistent with the interactional model of depression by showing that people with depression, and high levels of stress, are at heightened risk for experiencing IPV, even after controlling for their own propensity to enact IPV.

Intimate partner violence during pregnancy in Vietnam: role of husbands

Intimate partner violence (IPV) perpetrators are often husbands. Understanding factors pertaining to women's male partners is essential for programming interventions against IPV. The objective of the study was to describe husband-related social and behavioural risk factors and assess how they are associated with IPV during pregnancy. Cross-sectional data were collected among 1309 pregnant women with husbands in Dong Anh district, Vietnam. Information on sociodemographic characteristics of husbands, the husband's behaviour and the husband's involvement in pregnancy care was indirectly collected via women's report at first antenatal care visit. Data on exposure to intimate partner violence during pregnancy were collected when the women returned for antenatal care in 30-34 gestational weeks. Logistic regression analyses were used to measure the relationships between IPV during pregnancy and risk factors from the husband. Pregnant women who had husbands who were younger or blue-collar worker/farmer/unemployed had more likelihood to be exposed to IPV. Women with husbands who drank alcohol before sexual intercourse and gambled were more likely to be exposed to IPV repeated times. Those with husbands who had intentions of having a child had over three times increased OR to be exposed to IPV once (AOR = 3.2, 95% CI 1.1-9.7). If the husband had a preference for sons, the woman had 1.5 times increased OR (AOR = 1.5; 95% CI 1.1-1.9) to be exposed to IPV repeated times during pregnancy. This study highlights significant associations between IPV and maternal perceptions of husbands' behaviours and involvement in pregnancy. Findings may help to identify at-risk pregnant women to IPV and guide the development of targeted interventions to prevent IPV from husbands.

Physical and Emotional Sibling Violence in the Time of COVID -19

The COVID-19 pandemic has impacted families in a variety of ways with much being written on the potential impact of sheltering in place and quarantining on intimate partner violence and parent-to-child abuse. One area that has received scant attention is that of physical and emotional sibling violence. While physical and emotional sibling violence is a predominant form of family violence, discussion of violence between siblings in the time of COVID-19 has not received the attention it warrants. This article examines the potential for family stress to place siblings at risk for engaging in physical and emotional sibling violence and how this is exacerbated in the time of COVID-19. Also discussed is the the connection between physical and emotional sibling violence and other forms of family violence including intimate partner violence and parent-to-child abuse and neglect which underwrites the need to place physical and emotional sibling violence on the radar of practitioners, policy makers, and researchers. Finally, implications for practice, policy, and research on physical and emotional sibling violence in the context of COVID-19 are discussed.

Longitudinal Trajectory of Exposure to Psychological Interpersonal Violence

Psychological intimate partner violence (P-IPV) refers to verbal abuse from one partner to another and abuse of power or control from one partner to another. To date, no studies have examined the longitudinal course of P-IPV exposure among mothers or the effect that witnessing P-IPV can have on their children. Using latent class growth analysis, the current study identified five trajectory groups with the following intercept and growth characteristics: low stable, low-increasing, moderate-decreasing, high-decreasing, and consistently elevated. Membership in the four groups characterized by higher P-IPV exposure was predicted by maternal race and exposure to physical abuse. The children of mothers in the low-increasing and consistently elevated groups had elevated scores on the Internalizing and Externalizing scales of the Childhood Behavior Checklist. These findings remained after controlling for child sex, race, cumulative trauma exposure, and maternal depression.

The Interaction of Dopamine Genes and Financial Stressors to Predict Adulthood Intimate Partner Violence Perpetration

Three dopamine genes (DAT1, DRD2, and DRD4) have been associated with interpersonal delinquency, aggression, and violence when individuals experience adverse environmental exposures. Guided by the catalyst model of aggression, risk alleles identified in previous studies were hypothesized to be associated with intimate partner violence (IPV) perpetration in the presence of financial stressors, a possible environmental trigger. This hypothesis was tested using weighted, clustered logistic regression with data from the National Longitudinal Study of Adolescent to Adult Health. The direct effects DAT1, DRD2, and DRD4 on IPV perpetration, and the interaction of DAT1, DRD2, and DRD4 and financial stressors on IPV perpetration were assessed. Due to cell size, only White men and women were included in this analysis. Increasing number of financial stressors was associated with increased odds of IPV perpetration, regardless of DAT1, DRD2, and DRD4 alleles. As predicted, increasing number of financial stressors was more strongly associated with IPV perpetration among individuals with high-risk DAT1 alleles, than individuals with low-risk alleles. However, this relationship was inverted for DRD2. Although there was still a significant interaction between DRD2 and financial stressors, individuals with low-risk alleles had higher odds of IPV perpetration in the presence of financial stressors. A similar, nonsignificant relationship was found for DRD4. These findings indicate that these genes may interact differently with environmental exposures and types of violent behavior. In addition, the findings may, if replicated, suggest dopamine plays a different role in IPV perpetration compared with other forms of aggression and violence.

Research on Marital Satisfaction and Stability in the 2010s: Challenging Conventional Wisdom

Although getting married is no longer a requirement for social acceptance, most people do marry in their lifetimes, and couples across the socioeconomic spectrum wish their marriages to be satisfying and long-lasting. This review evaluates the past decade of research on the determinants of satisfaction and stability in marriage, concluding that the scholarship of the past ten years has undermined three assumptions that were formerly accepted as conventional wisdom. First, research exploiting methods like latent class growth analyses reveal that, for most couples, marital satisfaction does not decline over time but in fact remains relatively stable for long periods. Second, contrary to predictions of behavioral models of marriage, negative communication between spouses can be difficult to change, does not necessarily lead to more satisfying relationships when it is changed, and does not always predict distress in the first place. Third, dyadic processes that are reliably adaptive for middle-class and more affluent couples may operate differently in lower-income couples, suggesting that influential models of marriage may not generalize to couples living in diverse environments. Thus, the accumulated research of the last ten years indicates that the tasks of understanding and promoting marital satisfaction and stability are more complex than we appreciated at the start of the decade, raising important questions that beg to be answered in the years ahead.

Negative Interpersonal Interactions and Dating Abuse Perpetration: The Mediating Role of Dispositional Forgivingness

Theory and research suggest that an individual's negative interactions with his or her parents or romantic partner are associated with the perpetration of dating abuse. Research is beginning to explore the role of forgivingness within abusive romantic relationships, and these preliminary findings suggest that dispositional forgivingness might mediate the relations between negative interpersonal interactions and dating abuse. The current study assessed negative interactions with one's parents and one's romantic partner, the frequency of dating abuse perpetration, and dispositional forgivingness of others and oneself among a sample of emerging adults in college ( n = 421). Dispositional forgivingness of others was negatively associated with the perpetration of emotional/verbal dating abuse and threatening behaviors, and it mediated relations between negative interpersonal interactions and dating abuse perpetration. Our findings suggest that the tendency to forgive others may explain why some individuals who experience negative interpersonal interactions with parents or romantic partners do not escalate to perpetration of abuse within their romantic relationships. Implications for future research and application are discussed.

Longitudinal effects of increases and decreases in intimate partner aggression

Interventions aimed at reducing interpartner aggression assume that within-couple declines in aggression enhance individual and relational outcomes, yet reductions in aggression may fail to yield these benefits when other risk-generating mechanisms remain intact. The present study evaluates this possibility by investigating whether naturally observed within-couple changes in aggression are associated with improved individual and relational outcomes in the manner assumed by intervention programs. Drawing upon 4 waves of data collected at 9-month intervals from a community sample of 431 newlywed couples (76% Hispanic) living in low-income neighborhoods, Actor-Partner-Interdependence Modeling (APIM) and Structural Equation Modeling (SEM) indicated that levels of aggression at the outset of marriage had limited associations with later outcomes. Changes in aggression, however, were associated with subsequent marital outcomes, such that decreases in aggression were beneficial and increases in aggression were costly. Individuals who experienced increases in aggression worsened in their observed communication over time and reported greater increases in stress. Reports of stress early in marriage predicted escalations in aggression over time. Thus, helping couples to contain increases in aggression might be particularly consequential for their well-being.

Financial strain, trajectories of marital processes, and African American newlyweds' marital instability

The present study examined the longitudinal associations among financial strain, trajectories of marital processes, and increases in marital instability concerns among a sample of 280 African American newlywed couples followed over the first 3 years of marriage. Results from dyadic structural equation modeling revealed that financial strain experienced during the early years of marriage was associated with increased marital instability concerns for both husbands and wives. Latent growth curves of marital processes revealed mean declines in appraisals of spousal warmth and increases in appraisals of spousal hostility, with variability between individuals in rates of decline in warmth; further, wives' appraisals of spousal warmth covaried with levels of financial strain, such that high levels of financial strain were associated with steeper declines in spousal warmth appraisals. For both husbands and wives, rates of change in spousal warmth appraisals had a greater influence on increases in marital instability concerns than either starting levels of spousal warmth appraisals or financial strain. Findings highlight the long-term associations between external stress and trajectories of marital appraisals as well as their relative effects on marital distress. (PsycINFO Database Record

Uric acid excretion predicts increased aggression in urban adolescents

Elevated levels of uric acid have been linked with impulsive and disinhibited behavior in clinical and community populations of adults, but no studies have examined uric acid in relation to adolescent aggression. This study examined the prospective role of uric acid in aggressive behavior among urban, low income adolescents, and whether this relationship varies by gender. A total of 84 adolescents (M age 13.36years; 50% male; 95% African American) self-reported on their physical aggression at baseline and 1.5years later. At baseline, the youth also completed a 12-h (overnight) urine collection at home which was used to measure uric acid excretion. After adjusting for baseline aggression and age, greater uric acid excretion predicted more frequent aggressive behavior at follow up, with no significant gender differences. The results suggest that lowering uric acid levels may help reduce youth aggression.

Life Course and Intergenerational Continuity of Intimate Partner Aggression and Physical Injury: A 20-Year Study

The objective of this study is to examine continuity of intimate partner aggression (IPA), which is defined as repeated annual involvement in IPA, across respondents' life course and into the next generation, where it may emerge among adult children. A national, longitudinal, and multigenerational sample of 1,401 individuals and their adult children is analyzed. Annual data on IPA severity and physical injury were collected by the National Youth Survey Family Study across a 20-year period from 1984 to 2004. Three hypotheses and biological sex differences are tested and effect sizes are estimated. First, findings reveal evidence for life course continuity (IPA is a strong predictor of subsequent IPA), but the overall trend decreases over time. Second, intergenerational continuity is documented (parents' IPA predicts adult children's IPA), but the effect is stronger for female than for male adult children. Third, results from combined and separate, more restrictive, measures of victimization and perpetration are nearly identical except in the intergenerational analyses. Fourth, evidence for continuity is not found when assessing physical injury alone. Together, these findings imply that some but not all forms of IPA are common, continuous, and intergenerational. Life course continuity appears stronger than intergenerational continuity.

Associations of financial stressors and physical intimate partner violence perpetration

Background

Contextual factors, such as exposure to stressors, may be antecedents to IPV perpetration. These contextual factors may be amenable to modification through intervention and prevention. However, few studies have examined specific contextual factors. To begin to address this gap, we examined the associations between financial stressors and three types of physical IPV perpetration.

Methods

This analysis used data from Wave IV of The National Longitudinal Study of Adolescent to Adult Health. We used logistic regression to examine the associations of financial stressors and each type of IPV (minor, severe, causing injury), and multinomial logit regression to examine the associations of financial stressors and patterns of co-occurring types of IPV perpetration (only minor; only severe; minor and severe; minor, severe, and causing injury; compared with no perpetration).

Results

Fewer men perpetrated threats/minor physical IPV (6.7 %) or severe physical IPV (3.4 %) compared with women (11.4 % and 8.8 %, respectively). However, among physical IPV perpetrators, a higher percentage of men (32.0 %) than women (21.0 %) reported their partner was injured as a result of the IPV. In logistic regression models of each type of IPV perpetration, both the number of stressors experienced and several types of financial stressors were associated with perpetrating each type of IPV. Utilities nonpayment, housing nonpayment, food insecurity, and no phone service were associated with increased odds of perpetrating each form of IPV in adjusted analysis. Eviction was associated with perpetrating severe physical IPV but not threats/minor IPV or IPV causing injury. In multinomial logit regression comparing patterns of IPV perpetration to perpetrating no physical IPV, the relationships of financial stressors were less consistent. Food insecurity was associated with perpetrating only minor physical IPV. Comparatively, overall number of financial stressors and four types of financial stressors (utilities nonpayment, housing nonpayment, food insecurity, and disconnected phone service) were associated with perpetrating all three forms of physical IPV.

Conclusions

Combined with prior research, our results suggested interventions to improve financial well-being may be a novel way to reduce physical IPV perpetration.

A Questionnaire for the Assessment of Violent Behaviors in Young Couples: The Italian Version of Dating Violence Questionnaire (DVQ)

In the last years, intimate partner violence (IPV) became a relevant problem for community and for social life, particularly in young people. Its correct assessment and evaluation in the population is mandatory. Our objectives were: Confirm factor structure of Dating Violence Questionnaire (DVQ) and investigate its convergent and divergent validity. The DVQ along with other personality measures were filled by a sample of 418 university students (Females = 310) of average age of 23 y.o. (SD = 4.71). A subsample of participants (223 students) consented in being involved also in retest and filled also the Revised Eysenck Personality Questionnaire (short form) and a brief scale for describing the behavior of the (past) partner after the breaking of the relationship (BRS). The 8-factor structure, with respect to the two other competing models, reported better fit indexes and showed significant correlations with other personality measures. Personality traits, both Neuroticism and Psychoticism, correlated with Sexual Violence, while Detachment correlated only with Neuroticism and Coercion, Humiliation and Physical Violence correlated with only Psychoticism. Extraversion did not report significant relationships with any of the 8 DVQ factors. Also the predictive validity of DVQ was satisfactory with the partner violent reaction to the break of relationship predicted positively predicted by Coercion (b = 0.22) and by Humiliation (b = 0.20) and negatively by Emotional Punishment (b = -0.18). The present results indicate a good factor structure of the questionnaire, and interesting correlations with personality traits, allowing to identify psychological aspects with a predisposing role for anti-social aggressive behaviors. Further studies will be aimed at ascertaining other possible determinants of intimate partner violence and the weight of cultural aspects.

Perpetration and Victimization of Intimate Partner Aggression Among Rural Mothers

Intimate partner aggression is a leading cause of injury among women of child-bearing age. Research suggests that pregnancy and the postpartum period are times of increased vulnerability to aggression. Since rural women are at an increased risk of intimate partner aggression, research is needed to examine the role of pregnancy and the presence of children on intimate partner aggression among this vulnerable population. The purpose of this study is to examine the association between young children and intimate partner aggression victimization and perpetration among a rural sample. This analysis utilized data from biologic females of child-bearing age from the Keokuk County Rural Health Study, a cohort study of over 1,000 rural families conducted from 1994 to 2011. Crude and adjusted logistic regression was used to determine the relationship between having a young child and experiencing four forms of intimate partner aggression: verbal aggression perpetration, verbal aggression victimization, physical aggression perpetration, and physical aggression victimization. Having young children was significantly associated with increased odds of perpetrating verbal aggression but not victimization of verbal aggression or perpetration and victimization of physical aggression. This significant relationship persisted after adjustment for education, employment, or location of residence but not age or marital status. The increased odds of perpetrating verbal aggression among mothers in a rural area highlight the need for interventions designed for rural parents. One method of reducing intimate partner aggression may be to incorporate intimate partner aggression prevention activities into existing child abuse intervention activities.

Hostility, flooding, and relationship satisfaction: Predicting trajectories of psychological aggression across the transition to parenthood

Psychological aggression has been shown to have harmful effects on both partners, sometimes above and beyond the effects of physical aggression. However, very little is known about psychological aggression during the transition to parenthood. The transition to parenthood is a time where relationship satisfaction often declines and stress increases, which may put the couples at higher risk for psychological aggression. The purpose of this study was to examine if prenatal risk factors related to interpersonal style (specifically, emotional flooding and hostility) predict changes in psychological aggression from pregnancy to 2 years postpartum. Ninety eight couples took part in this study. The couples completed self-report questionnaires during pregnancy, 1 year postpartum, and 2 years postpartum. Both partners were asked about perpetrating and experiencing psychological aggression in their current relationship. Two level Hierarchical Linear Models (HLMs) were used to examine longitudinal associations between hostility, flooding, and psychological aggression. For women, hostility during pregnancy was a significant longitudinal predictor of psychological aggression. For men, flooding was a significant longitudinal predictor of psychological aggression. For both men and women, relationship satisfaction partially mediated the relationship between flooding/hostility and psychological aggression, indicating that women's hostile attitudes and men's tendency to be flooded tend to erode relationship quality, leading to increases in psychological aggression. This may represent a classic demand-withdraw dynamic in couples. The results indicate hostility for women and flooding for men are potential prenatal risk factors for future psychological aggression. Implications and future research directions are discussed. Aggr. Behav. 42:134-148, 2015. © 2014 Wiley Periodicals, Inc.

Relationship factors and trajectories of intimate partner violence among South African women during pregnancy and the postpartum period

Intimate partner violence (IPV) is a significant public health problem in South Africa. However, there is limited research on whether and how IPV changes during pregnancy and the postpartum period and on the factors that might affect women's risk during this time. In this study, we describe the mean trajectories of physical and psychological IPV during pregnancy and the postpartum period and examine whether relationship power, partner social support, and relationship stress are associated with women's trajectories of IPV. Data come from a longitudinal study with 1,480 women recruited during pregnancy between May 2008 and June 2010 at a public clinic in Durban. Women completed behavioral assessments at their first antenatal visit, at fourteen weeks and at nine months postpartum. Women's experiences of IPV were measured at all three time points and relationship power, partner social support and relationship stress were each measured at the baseline assessment. We used multilevel random coefficients growth modeling to build our models. The mean trajectory for both types of IPV was flat which means that, on average, there was not significant change in levels of IPV over pregnancy and the postpartum period. However, there was significant individual variability in trajectories of IPV over the study period. Women who had higher relationship power had lower levels of physical and psychological IPV over time than women with lower relationship power. Additionally, women with higher relationship stress and lower partner support had higher levels of psychological IPV at pregnancy. Interventions that maximize women's relationship power and partner social support and minimize relationship stress during this transformative time are needed.
