To offer a distinctively psychological perspective on these key social and mental health problems.

Scholarly review of the relevant literature.

This article presents a coherent model - the mediating psychological processes model - addressing the complex, interconnected, nature of these problems. The mediating psychological processes model suggests that disruption or dysfunction in psychological processes is a final common pathway in the development of mental disorder and social problems. The model proposes that biological, social and circumstantial factors lead to mental disorder, crime and other social problems through their conjoint effects in influencing or disrupting relevant psychological processes.

The implications for policy, and implementation of policy, are discussed.
