Crisis intervention is now an accepted form of brief therapy that has become the treatment of choice-for many individuals seeking to cope more effectively with life stresses. Recently, there has been an evolution of several disparate styles of crisis intervention in the direction of one convergent model. The screening/assessment style of crisis intervention, rooted in the medical model, and the problem-solving style, derived from the alternate services, are now converging. This evolution reflects a more uniformly accepted framework of concepts and principles on which to base the practice of crisis intervention.
