The proposed DSM definition offers nothing which would help a clinician understand or treat a patient suffering psychological symptoms.
Makes me happy to be a Jungian.
A proposed revision for the definition of a mental disorder is being addressed by select members of the Anxiety, Obsessive-Compulsive, Posttraumatic, and Dissociative Disorders Work Group, a member of the Mood Disorders Work Group, and additional individuals (see Stein DJ et al: What is a Mental/Psychiatric Disorders? From DSM-IV to DSM-V; Psychological Medicine, 2010; in press)
A. A behavioral or psychological syndrome or pattern that occurs in an individual
B. The consequences of which are clinically significant distress (e.g., a painful symptom) or disability (i.e., impairment in one or more important areas of functioning)
C. Must not be merely an expectable response to common stressors and losses (for example, the loss of a loved one) or a culturally sanctioned response to a particular event (for example, trance states in religious rituals)
D. That reflects an underlying psychobiological dysfunction
E. That is not primarily a result of social deviance or conflicts with society
