Obsessive-Complusive disorder-persistent, uncontrollable intrusions of unwanted thoughts (obsessions) and urges in sense less rituals (compulsions) 5. Post-Traumatic stress disorder-may appear immediately or months or years after a traumatic event -Biological factors:  Concordance rate-the % of twin pairs or other pairs of relatives who exhibit the same disorder  A moderate genetic predisposition to anxiety disorders  Anxiety sensitivity-make pple more vulnerable to anxiety disorders  Neurotransmitter abnormalities -Cognitive factors:  Pple: 1) misinterpret harmless situations as threatening. 2) focus excessive attention on perceived threats. 3) selectively recall info that seems threatening  Stress SOMATOFORM DISORDERS 1. Somatization disorder-marked by a history of diverse physical complaints that appear to be psychological in origin-mainly women 2. Conversion disorder-a sig loss of physical fxn (with no apparent organic basis), usually in a single organ system-ie. Vision/hearing loss, partial paralysis 3. Hypochondria-excessive preoccupation with health concerns and incessant worry about developing physical illness -Personality factors:  Self-centered, suggestible, excitable, overly dramatic/emotional pple  Neuroticism -Cognitive factors:  Think they are „sick‟  Overinterpret every ache or pain DISSOCIATIVE DISORDERS -pple lose contact with portions of their consciousness or memory, resulting in disruptions in their sense of identity -uncommon -3 syndromes: 1. Dissociative amnesia-a sudden loss of memory of important personal info that is too extensice to be due to normal forettting-ie.memory loss of a single traumatic event (ie.rape) 2.
