Community mobilisation is a promising new strategy for preventing intimate partner violence (IPV) against women in low-income settings. However, little is known about the contextual factors (e.g. socio-economic, cultural, historical and political conditions) that enable the effective mobilisation of communities for IPV prevention. This paper draws from the theoretical work of Campbell and Cornish (2010) on the relationship between context and community action in addressing HIV/AIDS to propose a framework for situating community mobilisation for IPV prevention in its surrounding symbolic, material and relational contexts. The framework is refined using empirical data from a case study of a gender-based violence (GBV) prevention intervention in Rwanda, including interviews with members of government-mandated GBV Committees and focus group discussions with members of two village communities (n=35). A thematic analysis identifies various contextual factors needed to support community mobilisation for IPV prevention, including: broad symbolic understandings of what constitutes IPV; capacity to economically support women who choose to leave violent relationships; mechanisms for addressing the silence that often surrounds IPV; support from policy and government authorities; and opportunities to effectively challenge inequitable policy and legal frameworks. This framework is useful for policy-makers and programme planners interested in IPV prevention in and by communities. Copyright (c) 2017 John Wiley & Sons, Ltd.
