ABNORMAL PSYCHOLOGY Chapter 3 Classification & Diagnosis Brief History of Classification th th In earlier times, (19 early 20 century), there was great inconsistency in the classification of abnormal psychology; different systems were used in different parts of the world The DSM (Diagnosis Statistic Manuel) was first published in 1959, then updated in 68 (DSM-II), and again in 87 (DSM-III), and finally in 94 (DSM-IV) The Diagnostic system of the American Psychiatric Association (DSM-IV and DSM-IV-TR) Mental Disorder is defined as a clinically significant behavioural or psychological syndrome or pattern that occurs in and individual and that is associated with present distress (i.e. painful symptoms) or disability (impairment in one or more areas of functioning) or with significantly increased risked of death, pain, disability, or an important loss of freedom. In addition, the syndrome cant be an expected response or culturally sanctioned response, must be a manifestation of a behaviour, psychological, or biological dysfunction Five Dimensions of Classification With the introduction of the DSM-III, came the mulitaxial classification where people are rated on 5 separate dimensions: Axis I: All diagnostic categories except for mental retardation and personality disorders Axis II: Personality disorders and mental retardation Axis III: General Medical Condition Axis IV: Psychosocial & Environmental problem (ex. occupational problems, economic problems, interpersonal difficulties with family members, etc.) Axis V: Current level of Functioning These five axes are for a diagnostician to consider a broad range of information Although there are 5 axes, all abnormal behaviour is placed within the first 2 axes, the rest are to provide additional information for the psychiatrist Most people come to be treated for Axis I disorders, however sometimes they previously had Axis II disorders, which is why they are separated from each other Disorders www.notesolution.com
