The landscape of mental health care and service delivery is changing, as is our understanding of the underlying causes for mental distress. It is now apparent that biogenic explanations have been overstated and instead experiences of trauma and adversity constitute the main contributor to people’s experiences of mental health challenges. The shortcomings of treatments traditionally used in mental health care are also evident, and with a contemporary focus on person-centred care, the utility of diagnostic labels has been called into question. Taking all this into consideration, this study sought to explore, what should be the future focus of mental health nursing? Three separate focus groups were conducted. One with a sample of senior clinical mental health nurses, one with a sample of consumer representatives and another with allied health professionals. The common theme across all three focus groups was the centrality of the therapeutic role of mental health nurses (MHNs). Consumers and allied health participants, in particular, advocated for a de-emphasis on medications, psychiatric diagnoses, and custodial practices. The MHNs role in health promotion, working collaboratively with consumers, being hopeful, understanding the individual perspective, and appreciating the social determinants of mental health were all highlighted in framing the future focus of MHN practice.
