This study employed a qualitative case study design to examine the child protection experiences of committed juveniles in Ghana's only juvenile correctional facility. Using purposive sampling, semi-structured interviews were conducted with 19 male juveniles aged 14–17 years who had been in the facility for at least three months. Data was analysed using Braun and Clarke's thematic analysis approach. Findings revealed three major themes: compromised quality of education due to resource constraints, inadequate nutrition stemming from severe under-resourcing, and reduced parental contact exacerbated by the centralized nature of Ghana's juvenile justice system. Through the lens of Bronfenbrenner's ecological systems theory, the study examines how these challenges manifest across different systemic levels.

Among these, obtaining research ethics approval, which is essential for ensuring research integrity and safeguarding participant welfare, stands out as a particularly critical and often arduous hurdle. Access to research ethics approval presents significant challenges for researchers in low- and middle-income countries (LMICs), due to: (1) limited availability and accessibility of appropriate Research Ethics Committees (RECs) at universities, hospitals, or other institutions; (2) difficulties in navigating bureaucratic ethical review systems; (3) limited access to funding for research ethics approval fees, particularly for early-career researchers; (4) fee-for-service ethics review models and associated conflicts of interest; (5) limited expertise of <span>REC</span> members to evaluate and advise on VAW and <span>VAC</span> research; and (6) conflicts between international <span>REC</span> criteria and local mandates or expectations regarding how research should be conducted.
