Study characteristics
Methods Study design: randomised controlled trial
Study grouping: parallel group
Duration of study: October 2010 to August 2012 (intervention ran from April 2011 to April 2012)
Location of study: 9 communities in South Kivu, Democratic Republic of the Congo
Randomisation method: 66 VSLA groups with 301 study women were available for randomisation in March 2011. The 66 groups were randomised into immediate start (intervention; 33 groups) and delayed start (control; 33 groups). The control groups did not receive VSLA training until year 2, when follow‐up data collection was completed.
Ethics approvals: study protocols were reviewed and approved by IRBs at the Johns Hopkins School of Public Health and Kinshasa School of Public Health.

Inclusion criteria
  • Women aged 18 years of age or older

  • Personally experienced or witnessed sexual violence (defined as rape locally)

  • A score of at least 10 on the function assessment (i.e. some dysfunction on at least half of the tasks questions)

Pretreatment: women in the control group reported more types of traumatic events, were more ethnically diverse, worked more hours, had more people they could rely on, expressed greater group membership and spent more money on food for the household.
Interventions Intervention characteristics
Other psychosocial interventions (VSLAs)
  • Intensity of intervention: 10 months

  • Mode of delivery (face‐to‐face, online, video, telephone, blend, with explanation): face‐to‐face

  • Format (group, individual, blend): group

  • Therapist qualifications and training appropriate (yes, no, unclear, with explanation): yes, the IRC is experienced at delivering the intervention.

  • Research allegiance or conflict of interest (yes, no, unclear, with explanation): no, none declared

  • Treatment fidelity (yes, no, unclear, with explanation): no, although the programme is described in detail in supplementary materials, there is no information on fidelity to the protocol.

  • Intervention aim and theoretical basis: VSLA model was developed by CARE International, based on indigenous savings and loans groups in Africa. VSLAs provide a community‐managed mechanism for savings, loans and insurance for people who cannot access banks or microfinance institutions. It was hypothesised that participation in VSLAs would provide women who lacked access to financial services access to savings and loans in the safety of a trusted group. It was also hypothesised that for women who had experienced sexual violence, participation in the group‐based economic programme would improve their ability to care for themselves and contribute to their family's well‐being, resulting in improved self‐efficacy and a reduction in mental health symptoms; it was hypothesised that women who had experienced sexual violence would improve their social connectedness through being part of the economic group and that this, together with increased economic benefits, would reduce their experience of stigma.
