New forms of evidence give a triangulated understanding about the promotion of well-being in mental health services. The academic discipline of positive psychology is developing evidence-based interventions to improve well-being. This complements the results emerging from synthesising narratives about recovery from mental illness, which provide ecologically valid insights into the processes by which people experiencing mental illness can develop a purposeful and meaningful life. The implications for health professionals are explored. In relation to working with individuals, more emphasis on the person's own goals and strengths will be needed, with integration of interventions which promote well-being into routine clinical practice. In addition, a more societally-focussed role for professionals is envisaged, in which a central part of the job is to influence local and national policies and practices that impact on well-being.
