Plain English Summary

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 worsen 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 investigate the effectiveness of this program at reducing psychological distress and preventing future intimate partner violence.

Who can participate?
Women who are refugees from the Democratic Republic of the Congo (DRC) currently living in Nyarugusu Refugee Camp (Tanzania) 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. These villages are randomly allocated to one of two groups. Participants living in villages in the first group take part in the Ngubu program. This 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 second group 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 24 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 April 2017

Study information

Scientific title

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

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

Nyarugusu is divided into 7 zones for Congolese refugees, which are further subdivided into 52 total villages. Staff not working for the project at Johns Hopkins Bloomberg School of Public Health will randomize villages into the intervention and control condition using approximately a 1:1 allocation ratio through a random number generator in the Statistical Package for the Social Science (SPSS). The allocation of villages to intervention and control condition will be concealed from the local research assistants.

Intervention (Nguvu) Arm: Participants will receive 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 24 weeks.
