Intimate partner violence is a global problem with devastating social and health consequences to individuals and families. While some forms of intimate partner violence such as physical and sexual violence have been explored in depth, there is a lack of clarity on men's perspectives of emotional violence, particularly in low-income countries. Yet it is recognized that incorporating men's perspectives and participation is crucial for addressing intimate partner violence. We draw from in-depth interviews with 30 men and 1, 645 pictures collected through photo voice to explore men's conceptualization and experiences of emotional violence by female partners in Mwanza, Tanzania. A sub-sample of the men (n = 16) were interviewed for a second time about pictures showing different aspects of their lives. The fieldwork was conducted between April and December 2019, and the data were analyzed through a multistage inductive process. Participants described emotional violence through a narrative of 'being hurt' by some actions or words of their partners. These included: verbal complaints about failure to provide for family, partner's infidelity and flirting with other men, accusation of poor sexual performance, and perceived normative deviance characterized by coming home late and not carrying out domestic chores. Threatened masculinities drawing from negative communal normative ideals, and the underlying interpersonal power struggles with their partners for the control of economic provision, sexual intimacy and family matters framed men's definitions of emotional violence. Ongoing changes such as women's ownership and engagement in economic activities and the scarcity of employment opportunities for men challenges their household dominance. Multicomponent interventions should target men, couples and communal ideals reinforcing negative masculinity. Analysis of interpersonal power and structural dynamics influencing relationships must inform the design of interventions instead of the narrow focus on individual demographic attributes.
