Recent research suggests that psychologists and counselors are dissatisfied with the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, and open to seeing the development of alternatives to it. Any alternative suitable for psychotherapists must meet certain requirements. A successful alternative must (a) place psychosocial factors on equal footing with biological factors; (b) categorize problems, not people; (c) be scientifically grounded; (d) be collaboratively developed; and (e) be usable across orientations, professions, and constituencies.
