The evolving nature of disaster mental health services.

It may be said that the field of emergency/disaster mental health is a mental health subspecialization that continues, even today, to quantitatively expand and qualitatively evolve. For this evolutionary process to continue successfully, greater sophistication must be realized both tactically, as well as strategically. This paper reviews the evolving nature of crisis intervention and emergency/disaster mental health. Three areas will be reviewed herein: the evolving goals of early intervention, tactical evolution, and the evolving nature of training in emergency/disaster mental health.
