This monograph attempts to set out the basic framework for suicide prevention strategies. It provides details in formulating and evaluating suicide prevention programs. The public health approaches suggested offer a multilayer intervention model, which has been adopted by a number of developed countries for setting up national prevention strategies. However, there is no single solution in dealing with suicide in a heterogeneous environment. Suicide prevention programs need to be evaluated. Where there is not necessary evidence, novel approaches must be simultaneously implemented and rigorously evaluated.
