Experiences of intimate partner violence (IPV) are associated with a wide range of measures of poor mental health. While there is a body of evidence to suggest that IPV leads to poor mental health, there is some evidence to suggest the association between IPV and mental illness may be bi-directional. We take data from a long running cohort study to test the hypothesis that poor mental health experienced during the adolescent and young adult periods of the life course predict adult occurring IPV. At 14 years respondents were administered the Youth Self Report (YSR), and at 21 years they completed the Young Adult Self Report (YASR) as well as the Composite International Diagnostic Interview. At 30 years, respondents completed the Composite Abuse Scale (CAS), with five measures of IPV; Severe Combined Abuse, Physical Abuse, Emotional Abuse, Harassment and Coercive Control. After adjustment for possible confounding, measures of delinquency and substance use disorder at 21 years predicted all forms of IPV. For example, in the fully adjusted data, substance use disorders to 21 years predict Severe Combined Abuse (2.30:1.15, 4.61), Physical Abuse (1.67:1.11, 2.52), and Coercive Control (1.74:1.14, 2.65) at 30 years. The findings raise the possible benefits of early intervention programs to reduce adult occurring IPV., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Although much available research indicates that intimate partner violence (IPV) is male perpetrated, growing recent evidence suggests a gender symmetry model of family violence. This article examines gender differences in IPV in current and prior relationships reported by young adults. Data comprised 2,060 young adults (62.1% females) who participated in the 30-year follow-up of the Mater Hospital and University of Queensland Study of Pregnancy (MUSP) in Brisbane, Australia. The Composite Abuse Scale was used to measure IPV during the last 12 months in the respondents' most recent relationship. Similar proportions of males and females reported leaving their prior relationships. Both males and females who were not currently in a relationship reported experiencing much higher rates of IPV than those who were in a relationship. There were no differences in the past experience of IPV between males and females who were not currently in a relationship, but males in a current relationship reported they experienced most forms of IPV more often than did females. IPV typically involves both male and female perpetrators and victims. It does appear that the majority of relationships involving higher rates of IPV were dissolved. IPV was more likely to have occurred in relationships that ended than in relationships that persisted. Males more often remain in an abusive relationship and report experiencing higher rates of IPV in their current relationships compared with females.

Poverty and socioeconomic disadvantage place demands on intimate relationships and provide fertile ground for disagreements and conflicts. It is not known whether poverty also leads to intimate partner violence (IPV). This study investigates the association between income and forms of IPV victimization for both males and females. We also examine whether income inequalities are related to IPV and whether the gender balance of household income contributes to IPV victimization. Data are from a cohort of 2,401 young offspring (60.3% females) who participated at the 30-year follow-up of the Mater-University of Queensland Study of Pregnancy in Brisbane, Australia. Participants completed questionnaires including their income details and the Composite Abuse Scale. Within low-income families, both partners experience higher levels of IPV. Females' income is not independently related to experiencing IPV either for females or males. Females and males experience a higher rate of IPV when the husband earns a low income. When considering partners' relative income, families in which both partners earned a low income experienced higher levels of almost all forms of IPV. Income (im)balance in which females earn more or partners both have higher income was less often associated with the experience OF IPV IPV appears to be mutually experienced in the setting of the poverty. Objective economic hardship and scarcity create a context which facilitates IPV for both partners in a relationship.

Purpose: The current longitudinal study examines the temporal association between different types of intimate partner violence (IPV) at early adulthood (21 years) and subsequent depression and anxiety disorders in young adulthood (30 years)., Methods: Participants were from the Mater-University of Queensland Study of Pregnancy. A cohort of 1529 was available for analysis. IPV was measured using the Composite Abuse Scale at 21 years. At the 21 and 30-year follow-ups, major depression disorder and anxiety disorders were measured using the Composite International Diagnostic Interview., Results: We found a temporal relationship between almost all forms of IPV at 21 years and females' new cases of major depression disorder at 30 years. This association was not found for females who had previously been diagnosed with depression disorder. IPV did not predict the onset of new anxiety disorders, but it had a robust association with anxiety disorders in females with a previous anxiety diagnosis. We observed no significant link between IPV and males' subsequent major depression disorder. Interestingly, the experience of emotional abuse was a robust predictor of new cases of anxiety disorders but only for males., Conclusion: Our results suggest the need for sex-specific and integrated interventions addressing both IPV and mental health problems simultaneously. IPV interventions should be informed by the extend to which pre-existing anxiety and depression may lead to different psychological responses to the IPV experience. Increased risk of anxiety disorders predicted by emotional abuse experienced by males challenges beliefs about invulnerability of men in the abusive relationships and demands further attention.

Aims: To examine the temporal association between the experience of different types of intimate partner violence (IPV) in early adulthood (21 years) and substance use disorders in young adulthood (30 years)., Design: Prospective birth cohort study using data from the Mater-University of Queensland Study of Pregnancy (MUSP)., Setting: Brisbane, Australia., Participants: A total of 1353 people (822 females and 531 males)., Measurements: IPV was measured using the Composite Abuse Scale (CAS) and alcohol, substance and nicotine use disorders were assessed using the Composite International Diagnostic Interview (CIDI)., Findings: In females, the experience of different forms of IPV at 21 years remained a robust risk factor for subsequent alcohol use disorder [adjusted odds ratios (aORs) ranged from 1.6 to 2.6 (all P < 0.05)], substance use disorder [aORs ranged from 2.1 to 4.0 (all P < 0.001)] and nicotine use disorder [aORs ranged from 2.0 to 2.4 (all P < 0.05)] at 30 years, even after controlling for antecedent substance disorders. However, in males only physical and emotional abuse (but not harassment) were significant in predicting alcohol use disorder [aORs ranged from 1.4 to 1.8 (all P < 0.05)] and drug use disorder [aORs ranged from 1.6 to 2.0 (all P < 0.05)] in the fully adjusted model., Conclusion: Intimate partner violence (IPV) in early adulthood is robustly associated with alcohol, substance and nicotine use disorders in women, whereas in men the association is clear for only some forms of IPV and types of disorder., (© 2019 Society for the Study of Addiction.)

There is some limited evidence of an association between maternal intimate partner victimization (IPV) and children's experience of maltreatment. Using data from a longitudinal study, we examine whether this relationship is independent of range of potential confounders including socio-economic, familial and psychological factors. Data were taken from the 14 and 30-year follow-ups of the Mater-University of Queensland Study of Pregnancy (MUSP) in Australia. A subsample of 2064 mothers and children (59.0% female) whose data on maternal IPV and child maltreatment was available, were analysed. In families with maternal IPV, two in five children reported being maltreated, compared to one in five children maltreated in families without maternal IPV. Except for sexual maltreatment which was consistently higher in female offspring, there was no gender differences in experiencing different types of maltreatment in families manifesting maternal IPV. Although both males and females were at increased risk of child maltreatment in families where mothers were victimized by their male partners, male children were more likely to be emotionally maltreated. The main associations were substantially independent of measured confounders, except for father's history of mental health problems which attenuated the association of maternal IPV victimization and male offspring's physical abuse. Our findings confirm that there is a robust association between maternal IPV and child maltreatment. Both maternal IPV victimization and child maltreatment co-occur in a household characterized by conflict and violence. Consequences of IPV go beyond the incident and influence all family members. Efforts to reduce child maltreatment may need to address the greater level of IPV associated with the cycle of family violence., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Background: This paper investigates gender differences in persistence of intimate partner violence (IPV), for those remaining or leaving an abusive relationship. We followed a sample of males and females to examine whether leaving an abusive partner may alter the continuity of victimization., Methods: Data were taken from the 21 and 30-year follow-ups of the Mater Hospital and University of Queensland Study of Pregnancy (MUSP) in Australia. A cohort of 1265 respondents, including 874 females and 391 males, completed a 21-item version of the Composite Abuse Scale., Results: We found proportionally similar rates of IPV victimization for males and females at both the 21 and 30 year follow-ups. Females who reported they had an abusive partner at the 21 year follow-up were more likely to subsequently change their partner than did males. Harassment and then emotional abuse appeared to have a stronger association for females leaving a partner. For males, a reported history of IPV was not significantly associated with leaving the partner. There was no significant association between leaving (or not) a previous abusive relationship and later victimization, either for male or female respondents., Conclusion: Changing a partner does not interrupt the continuity of victimization either for male or female respondents, and previous IPV victimization remained a determining factor of re-abuse, despite re-partnering.

Little is known about the associations between various types of childhood maltreatment and multiple forms of intimate partner violence victimization in early adulthood. This study examines the extent to which childhood experiences of maltreatment increase the risk for intimate partner violence victimization in early adulthood. Data for the present study are from 3322 young adults (55 % female) of the Mater Hospital-University of Queensland Study of Pregnancy with the mean age of 20.6 years. The Mater Hospital-University of Queensland Study of Pregnancy is a prospective Australian pre-birth cohort study of mothers consecutively recruited during their first antenatal clinic visit at Brisbane's Mater Hospital from 1981 through to 1983. Participants completed the Composite Abuse Scale at 21-year follow-up and linked this dataset to agency recorded substantiated cases of childhood maltreatment. In adjusted models, the odds of reporting emotional intimate partner violence victimization were 1.84, 2.64 and 3.19 times higher in physically abused, neglected and emotionally abused children, respectively. Similarly, the odds of physical intimate partner violence victimization were 1.76, 2.31, 2.74 and 2.76 times higher in those children who had experienced physical abuse, sexual abuse, neglect and emotional abuse, respectively. Harassment was 1.63 times higher in emotionally abused children. The odds of severe combined abuse were 3.97 and 4.62 times greater for emotionally abused and neglected children, respectively. The strongest associations involved reports of child emotional abuse and neglect and multiple forms of intimate partner violence victimization in young adulthood. Childhood maltreatment is a chronic adversity that is associated with specific and multiple forms of intimate partner violence victimization in adulthood.

Little is known about the extent to which parental conflict and violence differentially impact on offspring mental health and substance use. Using data from a longitudinal birth cohort study this paper examines: whether offspring exposure to parental intimate partner violence (involving physical violence which may include conflicts and/or disagreements) or parental intimate partner conflict (conflicting interactions and disagreements only) are associated with offspring depression, anxiety and substance use in early adulthood (at age 21); and whether these associations are independent of maternal background, depression and anxiety and substance use. Data ( n = 2,126 women and children) were taken from a large-scale Australian birth-cohort study, the Mater University of Queensland Study of Pregnancy (MUSP). IPC and IPV were measured at the 14-year follow-up. Offspring mental health outcomes – depression, anxiety and substance use were assessed at the 21-year follow-up using the Composite International Diagnostic Interview (CIDI). Offspring of women experiencing IPV at the 14-year follow-up were more likely to manifest anxiety, nicotine, alcohol and cannabis disorders by the 21-year follow-up. These associations remained after adjustment for maternal anxiety, depression, and other potential confounders. Unlike males who experience anxiety disorders after exposure to IPV, females experience depressive and alcohol use disorders. IPV predicts offspring increased levels of substance abuse and dependence in young adulthood. Gender differences suggest differential impact. [ABSTRACT FROM AUTHOR]
