Plain English Summary
Plain English summary as of 07/11/2018:
Background and study aims
Intimate partner violence is a major concern in refugee camps, as well as putting people at risk of mental health issues such as anxiety and depression (psychological distress). Studies have shown that psychological distress and intimate partner violence are directly related, in that intimate partner violence causes worse mental health and in turn mental health issues can increase risk of further intimate partner violence. It can be very difficult to break this cycle, and so an approach that addresses both mental health and the violence is necessary (integrated approach). The Nguvu (Kiswahili for strength and energy) project is an integrated approach designed to address these issues, through a combination of empowerment (providing information, discussing options and helping women make safe and informed choices to reduce violence) and psychological support (reducing emotional difficulties resulting from violence exposure). The aim of this study is to assess the relevance, acceptability and feasibility of a future definitive randomized controlled trial (RCT) evaluating the efficacy of an integrated intervention to reduce psychological distress and intimate partner violence for adult refugee women.
Who can participate?
Women who are refugees from the Democratic Republic of the Congo (DRC) currently living in Nyarugusu Refugee Camp (Tanzania) and participating in local women’s groups who have a history of intimate partner violence and are experiencing psychological distress.
What does the study involve?
The Nyarugusu Refugee Camp is divided into seven zones for Congolese refugees, which are further subdivided into 52 villages. Local women’s groups are organized within these villages and operate as opportunities for women to develop skills and strengthen their social networks. There are 59 women’s groups located in zones two through seven, which are randomly allocated into one of two study conditions: usual care with and without Nguvu. Participants recruited from women’s groups in the first group take part in the Nguvu program. Women’s groups in zone one are not included in the trial as this served as the sampling frame for our recently completed pilot study. The Nguvu program involves weekly sessions over eight weeks. Sessions one and eight focus on developing a safety plan and discussing issues surrounding intimate partner violence and psychological distress. Sessions two-seven focus on learning techniques to help identify stuck thoughts and learn skills to change ways of thinking that lead to psychological distress. Those living in villages in the usual care condition receive access to standard mental health and protection services during the eight week study period. This includes gender-based violence prevention and response services provided by the International Rescue Committee in Nyarugusu camp and mental health services provided by the Tanzania Red Cross. At the start of the study and then after nine and twenty weeks, participants in both groups complete a number of questionnaires to measure psychological distress and to find out if they have experienced any further intimate partner violence.
What are the possible benefits and risks of participating?
Participants who take part in the Nguvu program may benefit from reduced levels of distress and intimate partner violence. Participants who receive the standard care services are also likely to benefit in this way should they choose to use the services that are available. The main risks of this study involve possible discomfort when discussing personal topics related to mental health and intimate partner violence and social/safety risks if the participant’s partner or other community members are aware of their participation.
Where is the study run from?
The study is run from the Muhimbili University of Health and Allied Sciences and takes place in the Nyarugusu Refugee Camp (Tanzania)
When is the study starting and how long is it expected to run for?
October 2014 to October 2017
Who is funding the study?
1. Wellcome Trust (UK) Reference: R2HC initiative
2. Department for International Development (UK)

Nguvu: A randomized controlled trial of an integrated intervention to reduce intimate partner violence and psychological distress in adult, female Congolese refugees in Tanzania
Acronym
Study hypothesis
Study hypothesis as of 07/11/2018:
To assess the relevance, acceptability and feasibility of a future definitive randomized controlled trial (RCT) evaluating the efficacy of an integrated intervention to reduce psychological distress and intimate partner violence for adult refugee women
Previous study hypothesis:
1. Women in the intervention condition (consisting of the 8-session Nguvu intervention and access to intervention as usual) will report fewer incidents of intimate partner violence and experience less psychological distress post-intervention relative to intervention as usual
2. The intervention will increase social support/capital, self-efficacy and adaptive coping skills, which will further reduce recurrent intimate partner violence and psychological distress

Condition
Psychological distress (e.g. depressive, anxiety or post-traumatic stress symptoms) in refugees with a past-year history of intimate partner violence
Intervention
Correct as of 12/06/2017:
Nyarugusu is divided into 7 zones for Congolese refugees, which are further subdivided into 52 total villages.
One of the zones (zone 1) will be excluded from the trial because it was used as the site for the pilot study. In zones 2-7 there are 59 women’s groups organized within the villages, which will serve as the cluster and source of recruitment for the study.
Staff not working for the project at Johns Hopkins Bloomberg School of Public Health will randomize women’s groups in zones 2-7 into the intervention and control condition using approximately a 1:1 allocation ratio through a random number generator in the Stata. The allocation of villages to intervention and control condition will be concealed from the local research assistants.
Intervention (Nguvu) Arm: Participants will have access to the Nguvu intervention, which is an 8-week program that integrates advocacy and empowerment counseling with cognitive processing therapy. The intervention was developed from previous programs evaluated in survivors of sexual and gender-based violence and adapted through formative research conducted in Nyarugusu refugee camp. The intervention consists of weekly sessions over the course of 8 weeks (1 individual session followed by 7 group sessions). Sessions 1 and 8 are the advocacy sessions, which focus on developing a safety plan and discussing issues surrounding intimate partner violence and psychological distress. Sessions 2-7 are the cognitive processing therapy sessions that introduce concepts and the relationship between thoughts and feelings and teach participants skills to identify stuck thoughts and introduce skills to change thinking errors as a means to improve feelings and reduce psychological stress.
Comparison group: Participants will receive standard mental health and protection services during the trial period. Protection services include gender-based violence prevention and response services provided by the International Rescue Committee in Nyarugusu camp. The mental health services are provided primarily through the health sector, primarily provided by the Tanzania Red Cross, and some psychosocial services are offered through the protection sector.
Participants in both groups are followed up after 9 and 20 weeks.
