Session Description
Our symposium presents the latest evidence on the relationship between mental health and intimate partner violence (IPV). ROXANNE KEYNEJAD presents a meta-analysis investigating whether IPV victimisation moderates the effectiveness of brief psychological interventions for common mental disorders in low and middle-income countries. Data from 15 randomised controlled trials were meta-analysed. Anxiety symptoms of women experiencing IPV (five interventions, n=728) reduced more following intervention than in women not experiencing IPV. Similar but non-significant effects were found for post-traumatic stress (eight interventions, n=1436), depressive symptoms (12 interventions, n=2940), and psychological distress (four interventions, n=1591). KATHERINE SAUNDERS presents an individual participant data meta-mediation analysis of four datasets (n=12,679) investigating the association between depression and past-year physical IPV perpetration and whether the association is mediated by alcohol misuse or past year IPV victimisation. There was a 7.4% and 4.8% proportion increase in IPV perpetration among women and men with depression compared to those without, respectively. Among women, past-year IPV victimisation mediated 45% of the effect of depression on past-year IPV perpetration. There was no mediation by alcohol misuse in either sex. GERI McLEOD presents data from a New Zealand birth cohort of 1265 babies (630 females) born in 1977, the Christchurch Health and Development Study. IPV (victimization, perpetration, combined) and mental health information was gathered for approximately 1000 cohort members from ages 25-40 years. Trajectory models identified IPV patterns; regression methods described the people who clustered onto each trajectory. Regression analyses focused on mental health as both a predictor and an outcome of IPV.

Abstract Body

Background

The evidence base for psychological interventions among women experiencing common mental disorders (CMDs) and intimate partner violence (IPV) in low and middle-income countries (LMICs) is limited.

Methods

For this systematic review and meta-analysis (PROSPERO: CRD42017078611), we searched MEDLINE, Embase, PsycINFO, Web of Knowledge, Scopus, CINAHL, LILACS, ScieELO, Cochrane, PubMed databases, trials registries, 3ie, Google Scholar, forward and backward citations up to 16/08/2019. Eligible studies were randomised controlled trials (RCTs) of psychological interventions for CMDs in LMICs which measured IPV; there were no language/date restrictions. We obtained unpublished aggregate sub-group data for women who did and did not report IPV from study authors, enabling separate random-effects meta-analyses for anxiety, depression, post-traumatic stress disorder (PTSD) and psychological distress outcomes.

Findings

Out of 8122 records identified, 21 were eligible and we obtained data for 15 RCTs (all were at low-moderate risk of bias). Anxiety (n=5 RCTs; N=728 participants) showed a greater response to intervention among women reporting IPV than those who did not (difference in standardised mean differences: dSMD=0.31, 95% confidence interval: CI=0.04, 0.57, I2=49.4%). Consistent but smaller directions of effect favoured women reporting IPV for improvements in PTSD (n=8/N=1436; dSMD=0.14, CI=-0.06, 0.33, I2=42.6%), depression (n=12/N=2940; dSMD=0.10, CI=-0.04, 0.25, I2=49.3%) and psychological distress (n=4/N=1591; dSMD=0.07, CI=-.05, 0.18, I2=0%).

Interpretation

Women with current/recent experience of IPV can benefit from psychological interventions for CMDs and should be offered them, where available, in LMICs.

Abstract

Abstract Body

KATHERINE SAUNDERS presents an individual participant data meta-mediation analysis of four datasets (n=12,679) investigating the association between depression and past-year physical IPV perpetration and whether the association is mediated by alcohol misuse or past year IPV victimisation. This study was an individual participant data meta-analysis. Results showed a 7.4% and 4.8% proportion increase in IPV perpetration among women and men with depression compared to those without, respectively. Among women, past-year IPV victimisation mediated 45% of the effect of depression on past-year IPV perpetration. There was no mediation by alcohol misuse in either sex. Clinicians and staff working in mental health services, criminal justice services and domestic violence perpetrator programmes should be aware i) of the association between depression and IPV perpetration and ii) that, among women, efforts to reduce IPV victimisation may also help to also reduce IPV perpetration. Future research should aim to improve data collection on mental disorder and IPV perpetration, with a particular focus on consistency across population-based surveys.

Abstract

Abstract Body

Aims and Objectives. Previous research has examined the prevalence and lifecourse trajectories of Intimate Partner Violence (IPV) among male and females. The aim of this study is to present lifecourse trajectories of IPV from young to mid-adulthood and examine the contribution of mental health disorder to this problem.

Methods. Data were gathered from the Christchurch Health and Development Study (CHDS), a birth cohort of 1265 babies (630 females) born in 1977 in Christchurch, New Zealand. Measures of IPV (victimization, perpetration, combined) and mental health information were gathered for approximately 1000 cohort members at ages 25, 30, 35 and 40 years.

Results. Tabular analyses showed that for both male and female participants, IPV perpetration and victimization was common, reflecting gender symmetry. That is, there was no evidence to suggest that males were more violent in their relationships than females. Trajectory models identified IPV patterns from young to mid-adulthood which showed that, in general, rates of IPV perpetration and victimisation reduced with maturity of the cohort. However, a small proportion of the cohort continued to be violent in their partner relationships. Regression methods describe the cohort members who clustered onto each trajectory. These regression analyses controlled for a series of childhood background factors and IPV experienced concurrently with mental disorder.

Discussion. Many partner relationships have IPV perpetration and victimisation which is not restricted to male-on-female violence only. Over time, many couples will mature out of violence. Mental disorder makes a small but significant contribution to the perpetuation of violence over the lifecourse.
