This thesis explores the ethical and methodological challenges faced in researching intimate partner violence (IPV) against African male migrants, a highly under-researched population. IPV is a critical global health issue, but its impact on men, particularly male migrants, remains largely ignored due to societal biases that typically label men as perpetrators rather than victims. African male migrants are particularly vulnerable due to the intersection of migration stressors, cultural biases and expectations, and the lack of targeted support services. The study employs a Critical Interpretive Synthesis (CIS) approach to review existing literature on IPV in migrants, asylum seekers/applicants for international protection seekers and refugees (MARs), focusing on the ethical and methodological challenges that researchers face when studying this sensitive topic. The thematic findings identified challenges include obtaining informed consent, ensuring anonymity and confidentiality, building trust, balancing non-maleficence and beneficence, and ensuring privacy. It also identified methodological challenges, such as participant selection, language barriers, interviewer characteristics, sample size, reproducibility, transparency, and data collection methods. Social Added Value and Impact The social-added value of this thesis lies in its emphasis on a neglected population—African male migrants—who are often overlooked in IPV research and support services. By highlighting the unique ethical and methodological challenges in researching this group, the study advocates for more inclusive and culturally sensitive research practices. In addition, it contributes to a broader understanding of IPV that transcends gender stereotypes, encouraging a more equitable approach to victim protection and support. The social impact of this work is significant and include: Improved Research Practices: The study recommends ethical and methodological sensitivity to conduct more sensitive and effective studies in similar hard-to-reach populations, ultimately contributing to better health and social outcomes for marginalised communities. Awareness Raising: By focusing on male victimisation, this research challenges the prevailing gender stereotypes and promotes a more balanced discourse on IPV, encouraging society to recognise and support all victims, regardless of gender. Policy Development: The recommendations for policymakers include creating gender-neutral policies and enhancing support services for male victims. These changes will lead to more inclusive support services that cater to both male and female victims of IPV and promote social justice and equity in public health interventions.
