The descriptive models of self-mutilation fall into three broad categories. The psychodynamic formulation; the second category includes the anxiety reduction model, the hostility model, the behavioral learning model and the appeal model; the third social learning category includes the group-epidemic model and aspects of the violence and punishment model. The three models support the view that there is no single cause or motive responsible for self-mutilating behavior. Having a number of factors in mind allows for flexibility and enables clinicians to test particular hypotheses during management and gives them the opportunity to alter intervention accordingly. The problems faced by self-mutilating patients are so varied that no single form of treatment is likely to be universally appropriate.
