Mental Disorders "a clinically significant behavioral or psychological syndrome or pattern that occurs in an individual and that is associated with present distress (e.g., a painful symptom) or disability (i.e., impairment in one or more important areas of functioning) or with a significantly increased risk of suffering death, pain, disability, or an important loss of freedom."--Diagnostic & Statistical Manual of Mental Disorders 4th Ed.

Classifying Psychological Disorders The American Psychiatric Association rendered a Diagnostic and Statistical Manual of Mental Disorders (DSM) to describe psychological disorders. The most recent edition, DSM-IV-TR (Text Revision, 2000), describes 400 psychological disorders compared to 60 in the 1950s. Will be revised in 2013. Working on revisions now and they are available for review online. OBJECTIVE 3| Describe the goals and content of the DSM-IV.

The DSM spells out the specific diagnostic criteria An example of this can be seen in the diagnosis of a major depressive episode. When diagnosing a client the American Psychological Association recommends that the clinician use a multiaxial Assessment System.

Multiaxial Classification Axis I Is a Clinical Syndrome (cognitive, anxiety, mood disorders [16 syndromes]) present? Axis II Is a Personality Disorder or Mental Retardation present? Axis III Is a General Medical Condition (diabetes, hypertension or arthritis etc) also present? Axis IV Are Psychosocial or Environmental Problems (school or housing issues) also present? Axis V What is the Global Assessment of the person’s functioning? (GAF Scale is out of 100 with the lower the school the more limited their functionioning.

Goals of DSM Describe (400) disorders. Determine how prevalent the disorder is. Disorders outlined by DSM-IV are reliable. Therefore, diagnoses by different professionals are similar. Others criticize DSM-IV for “putting any kind of behavior within the compass of psychiatry.”
