Abstract
World health reports highlight the increasing prevalence of mental health problems and the need to recognize that mental well‐being is a fundamental aspect of any health policy. The scale and cost of mental health problems mean that appropriate policies and strategies must be developed and implemented. In Ireland this is a period of substantial review and reflection on mental health policy and practice, but to date little consideration has been given to the development of a cross‐border strategy. Cooperation and collaboration has been largely dependent on the leadership of a number of individuals supported by short‐term European Union funding. This paper is informed by a study which was concerned with examining the issues associated with promoting mental health across the Irish border. Insights were provided by 38 individuals who were involved in the delivery of cross‐border mental health services in the North West region. The article argues that there is substantial support for working across borders and developing sustainable cross‐border health strategies. In the absence of a statutory all‐Ireland coordinated policy overseeing the development of mental health promotion, the sustainability of projects emerged as a key issue. The results suggest that whilst much innovative and creative work has been undertaken by committed individuals, what is now required is a strategic response from both the British and Irish governments which will ensure the needs of service users in these deprived border regions can be effectively addressed. Also, at a policy level this strategic development would be seen as a reflection of the value placed on promoting mental health and well‐being.
