In this module you will explore complex social issues that intersect health and criminal justice systems, such as social and economic inequalities, adverse childhood experiences, vulnerability to violence (particularly gender-based violence in domestic settings), mental health crises, substance use and associated harms such as HIV infection, dementia, and commercial sex work and exploitation. You will delve into the multidimensional nature of these issues, comparing public health and criminal justice perspectives and examining a range of interventions, legislation, policy, and strategic responses employed by both sectors. You will critically analyse the synergies and tensions between the disciplinary perspectives of public health and criminology, enhancing your theoretical understanding and evaluation skills. Reflecting on shared and differing occupational cultures, you will explore the facilitators and barriers to service engagement, gaining insight into the implications for health/justice-involved populations.
