Pathways to reduced physical intimate partner violence among women in north-western Tanzania: Evidence from two cluster randomised trials of the MAISHA intervention.

Intimate partner violence (IPV) affects over one-in-four women globally. Combined economic and social empowerment interventions are a promising IPV prevention model. However, questions remain on the mechanisms through which such interventions prevent IPV, and whether standalone social empowerment interventions can work in the absence of an economic component. This secondary analysis of MAISHA Study data (north-western Tanzania) explores pathways through which a group-based gender-training intervention, delivered to women standalone or alongside microfinance, may impact on physical IPV risk. Two cluster-randomised trials (CRT) assessed the impact of the MAISHA intervention on women's IPV risk; CRT01 among women in 66 pre-existing microfinance groups (n = 919), and CRT02 among 66 newly-formed groups not receiving microfinance (n = 1125). Women were surveyed at baseline and 29 months follow-up. Sub-group analyses explored whether intervention effects on past-year experience of physical IPV varied by participant characteristics. Mediators of intervention effect on physical IPV were explored using mixed-effects logistic regression (disaggregated by trial). In CRT01, MAISHA was associated with reduced past-year physical IPV (adjusted-OR 0.63, 95%CI 0.41-0.98), with stronger effects among those younger, more financially independent, and without prior physical IPV. CRT02 showed no impact on physical IPV, overall or among sub-groups. In CRT01, individual-level reduced acceptability of IPV and group-level confidence to intervene against IPV emerged as potential mediators of intervention effect, while relationship-level indicators of communication were not impacted. In CRT02, positive impacts on individual-level attitudes did not translate into reduced IPV risk. In CRT02, arguments with partners over perceived transgressions of gender roles increased in the intervention-arm. Neither trial resulted in increased separations. Findings illustrate the importance of addressing poverty and women's economic dependence on men, structural factors that may impede the success of socially oriented violence prevention programming. Programming with men is also crucial to ameliorate risks of backlash against attitudinal/behavioural change among women. Trial registration: ClinicalTrials.gov #NCT02592252.

The short and long-term impact of COVID-19 restrictions on women's mental health in Mwanza, Tanzania: A longitudinal study.

The COVID-19 outbreak had a profound impact on all countries in the world, leading governments to impose various forms of restrictions on social interactions and mobility, including complete lockdowns. While the impact of lockdowns on the emerging mental health crisis has been documented in high income countries, little is known whether and how the COVID-19 pandemic also effected mental health in settings with few or no COVID-19 restrictions in place. Our study therefore aimed to explore the impact of few and no COVID19 restrictions on the self-reported mental health of women in Mwanza, Tanzania. The longitudinal study integrated a nested phone survey with two time points into an existing longitudinal study in Mwanza, Tanzania. In total, 415 women who were part of an existing longitudinal study utilizing face-to-face interviews participated in both phone interviews, one conducted during COVID-19 restrictions and once after the restrictions had been lifted about the prior three months of their lives. They also participated in a face-to-face interview for the original longitudinal study three months later. Using a random effects model to assess changes in symptoms of poor mental health, measured through the SRQ20, we found a significant difference between the time during COVID-19 restrictions (20%) and after COVID-19 restrictions were lifted (15%), and after life resumed to pre-COVID-19 times (11%). Covid-19 related factors associated with poor symptoms of mental health during restrictions and after restrictions were lifted related to COVID-19 knowledge, behaviour change, economic livelihoods challenges, increased quarrels and intimate partner violence with partners and stress due to childcare issues. Despite Tanzania only imposing low levels of restrictions, the COVID-19 pandemic still led to an increase in women's reports of symptoms of poor mental health in this study, albeit not as pronounced as in settings with strict restrictions or lockdown. Governments need to be aware that even if no or low levels of restrictions are chosen, adequate support needs to be given to the population to avoid increased anxiety and challenges to economic livelihoods. In particular, attention needs to be given to the triple burden that women face in respect to reduced income generating activities, relationship pressures and increased childcaring responsibilities.

Disability and intimate partner violence: A cross-sectional study from Mwanza, Tanzania.

BACKGROUND: Women with disabilities are at heightened risk of experiencing intimate partner violence [IPV], although the mechanisms through which disability acts as a risk factor for IPV are not clear. OBJECTIVE: We analyzed cross-sectional data (n = 867) from Wave 3 of the MAISHA longitudinal study, conducted in Mwanza, Tanzania, to i) describe the levels of disability and IPV amongst women, and ii) to assess the association between level and type of disability and IPV experience. METHODS: IPV was assessed using the WHO Multi-Country study instrument. Levels of disability (none, mild and severe) were categorized based on responses to the Washington Group Short Set questions. We fitted logistic regression models to determine the risk of experiencing each type of IPV according to disability level and type of disability. RESULTS: We found significant associations between mild and severe disability and different types of IPV. For example, in multivariate analyses controlling for socio-demographic variables, women reporting severe disability were significantly more likely to report physical and/or sexual IPV, sexual IPV. controlling behaviors, economic IPV, and severe IPV, whereas for mild disability compared to no disability, physical and/or sexual IPV, sexual IPV, and economic IPV were significantly more likely to be reported. Cognitive disability was a significant correlate of all forms of IPV apart from physical IPV. CONCLUSIONS: Our findings that specific types of disability and not others were associated with an elevated risk of IPV exposure indicate the need for nuanced measurement and analysis of the association between disability and IPV.

Longitudinal inconsistencies in women's self-reports of lifetime experience of physical and sexual IPV: evidence from the MAISHA trial and follow-on study in North-western Tanzania.

BACKGROUND: Intimate partner violence (IPV) against women is pervasive throughout the world, with profound consequences for women's health. Research to understand the extent, causes and consequences of IPV relies on self-reported data on violence, and yet there is a paucity of research into the consistency with which women report lifetime IPV over time. METHODS: We use data from the control group of the cluster randomised trial and a follow-on longitudinal study in Tanzania to examine discrepancies in women's reported experience of lifetime physical IPV and sexual IPV over three time-points (T0, T29, T53 months). Among those reporting lifetime history of IPV at T0, we calculate the proportion who subsequently report no lifetime history at T29 and/or T53 ('discrepant' reporting). We use logistic regression to explore associations between discrepant reporting and respondent baseline characteristics, the nature of their IPV experiences at baseline, and situational factors at T53. RESULTS: Complete IPV data were available for 301 women. At T0, 154 (51%) women reported lifetime history of physical IPV, of whom 62% gave a discrepant 'never' report in a subsequent round. Among 93 (31%) with lifetime history of sexual IPV at T0, 73% provided a subsequent discrepant report. 73% of women reported lifetime physical IPV, and 55% lifetime sexual IPV in at least one survey round. For both IPV outcomes, women were less likely to provide discrepant reports if they had recent IPV at baseline, poor mental health (T53) and poor communication with partner (T53). For physical IPV only, reduced discrepant reporting was also associated with baseline household-level financial hardship and more severe or extensive experience of IPV. CONCLUSIONS: A large proportion of women provided discrepant reports over the course of the study. Prevalence estimates of lifetime IPV from one-off cross-sectional surveys are likely to be underestimates, biased towards more recent and severe cases. To improve the stability of IPV measures, researchers should explicitly clarify the meaning of reference periods such as 'ever', consider using shorter reference periods (e.g. past-year), and avoid filter questions that use positive reports of lifetime IPV as a gateway to asking about more recent experiences.

A cluster randomised controlled trial to evaluate the impact of a gender transformative intervention on intimate partner violence against women in newly formed neighbourhood groups in Tanzania.

INTRODUCTION: Violence against women is a global public health concern; around a quarter of women will experience intimate partner physical or sexual violence during their lifetime. We assessed the impact of a gender transformative intervention for women designed to prevent intimate partner violence (IPV). METHODS: We conducted a cluster randomised controlled trial in Mwanza city, Tanzania, among women in newly formed neighbourhood groups to evaluate a 10-session participatory intervention that aims to empower women, prevent IPV and promote healthy relationships. Following a baseline interview, groups were randomly assigned (1:1 ratio) to the intervention or control arm. An intention-to-treat analysis was conducted to assess the impact of the intervention on the main outcomes, assessed 24 months postintervention. These included past-year physical IPV and sexual IPV (primary); past-year emotional abuse; and acceptability and tolerance of IPV. RESULTS: Between September 2015 and February 2017, 1265 women were recruited in 66 neighbourhoods and randomly allocated to intervention (n=627 women in 33 neighbourhoods) or control (n=638 women in 33 neighbourhoods). Assessment of outcomes was completed for 551 (88%) intervention and 575 (90%) control women. Among intervention women, 113 (21%) reported physical IPV compared with 117 (20%) control women (adjusted OR (aOR) 0.98, 95% CI 0.72 to 1.33, p=0.892), and 109 (20%) intervention women reported sexual IPV compared with 121 (21%) control women (aOR 0.98, 95% CI 0.72 to 1.32, p=0.881). Intervention women reported less emotional abuse (aOR 0.74, 95% CI 0.56 to 0.98, p=0.035), and were less likely to express attitudes accepting of IPV (aOR 0.49, 95% CI 0.36 to 0.66, p<0.001), and beliefs that IPV is a private matter (aOR 0.54, 95% CI 0.38 to 0.78, p=0.001), or should be tolerated (aOR 0.48, 95% CI 0.34 to 0.66, p<0.001). CONCLUSION: These results indicate that the intervention was effective in reducing emotional abuse and positively impacting attitudes and beliefs condoning IPV, but was not sufficient to reduce physical or sexual IPV.

A social empowerment intervention to prevent intimate partner violence against women in a microfinance scheme in Tanzania: findings from the MAISHA cluster randomised controlled trial.

BACKGROUND: Globally, about 30% of women have experienced physical or sexual violence, or both, from an intimate partner during their lifetime. Associations between poverty and women's increased risk of intimate partner violence have been observed. We therefore aimed to assess the effect of a violence prevention intervention delivered to women participating in a group-based microfinance scheme in Tanzania. METHODS: We did a cluster randomised controlled trial among women taking part in a microfinance loan scheme in Mwanza city, Tanzania. A microfinance loan group was only enrolled if at least 70% of members consented. We randomly assigned the microfinance groups in blocks of six to receive either the intervention (ie, the intervention arm) or be wait-listed for the intervention after the trial (ie, the control arm). Women in both arms of the trial met weekly for loan repayments. Only those in the intervention arm participated in the ten-session MAISHA intervention that aims to empower women and prevent intimate partner violence. Given the nature of the intervention, it was not possible to mask participants or the research team. The primary outcome was a composite of reported past-year physical or sexual intimate partner violence, or both. Secondary outcome measures were past-year physical, sexual, and emotional intimate partner violence; acceptability and tolerance of intimate partner violence; and attitudes and beliefs related to intimate partner violence. These outcomes were assessed 24 months after the intervention. An intention-to-treat analysis was done, adjusting for age, education, and baseline measure of the respective outcome. The study is registered with ClinicalTrials.gov, number NCT02592252. FINDINGS: Between September, 2014, and June, 2015, 66 (65%) of 101 microfinance groups approached in the study area met the trial eligibility criteria and were enrolled, of which 33 (n=544 women) were allocated to the intervention arm and 33 (n=505 women) to the control arm. Overall, 485 (89%) of 544 women in the intervention arm and 434 (86%) of 505 in the control arm completed the outcomes assessment. Among the intervention arm, 112 (23%) of 485 women reported past-year physical or sexual intimate partner violence, or both, compared with 119 (27%) of 434 in the control arm (adjusted odds ratio [aOR] 0·69, 95% CI 0·47-1·01; p=0·056). Women in the intervention arm were less likely to report physical intimate partner violence (aOR 0·64, 95% CI 0·41-0·99; p=0·043) and were less likely to express attitudes accepting of intimate partner violence (0·45, 0·34-0·61; p<0·0001) or beliefs that intimate partner violence is a private matter (0·51, 0·32-0·81; p=0·005) or should be tolerated (0·68, 0·45-1·01; p=0·055). There was no evidence of an effect on reported sexual or emotional intimate partner violence. There were no reports that participation in the trial had led to new episodes of violence or worsening of ongoing violence and abuse. INTERPRETATION: Reported physical or sexual intimate partner violence, or both, was reduced among women who participated in the intervention arm, although the effect was greater for physical intimate partner violence, suggesting that intimate partner violence is preventable in high-risk settings such as Tanzania.
