Psychology in Action (9e) { Chapter 14: Psychological Disorders Studying Psychological Disorders Abnormal Behavior: patterns of emotion, thought, & action considered pathological for one or more of four reasons: • statistical infrequency • disability or dysfunction • personal distress • violation of norms Studying Psychological Disorders: Four Criteria for Abnormal Behavior Page 476 of text Culture-General Symptoms: shared symptoms across cultures Culture-Bound Symptoms: unique symptoms that differ across cultures Studying Psychological Disorders (Continued) Historical perspectives: In ancient times, people believed demons were the cause of abnormal behavior, & boring holes in the skull (trephining) allowed evil spirits to escape. In the 1790s, Pinel & others emphasized disease & physical illness, which led to the medical model & later to modern psychiatry. Studying Psychological Disorders (Continued) Modern psychology includes seven major perspectives on abnormal behavior. Studying Psychological Disorders: Classifying Abnormal Behavior Diagnostic & Statistical Manual of Mental Disorders (DSM-IV-TR): provides detailed symptom descriptions • contains over 200 diagnostic categories grouped into 17 major categories & five dimensions (or axes) • Studying Psychological Disorders: Classifying Abnormal Behavior (Cont.) Five Axes of DSM-V-TR (guidelines for making decisions about symptoms; attempts to address the ‘whole person’ ) • • • • • Axis I (principal disorder needing immediate attention) Axis II (personality disorders contributing to the above disorder) Axis III (general medical information relevant to above disorder) Axis IV (psychosocial & environmental problems contributing to disorder) Axis V (global assessment of level of functioning – how are they coping?) Labelling with the DSM While the DSM is the accepted manual for diagnosing mental disorders, there are many who argue its limitations Biggest argument – definitions are too vague For example: Manic depressive or bipolar Mood Disorders are characterized by dramatic "mood swings" or episodes of Mania or Major Depression. Is there still an advantage to using the guide? Anxiety Disorders Anxiety Disorder: overwhelming apprehension & fear accompanied by autonomic nervous system (ANS) arousal Five Major Types: Generalized Anxiety Disorder Panic Disorder Phobias Obsessive-Compulsive Disorder (OCD) Posttraumatic Stress Disorder (PTSD) (Discussed in Chapter 3) 1. 2. 3. 4. 5. Five Types of Anxiety Disorders 1. Generalized Anxiety Disorder: persistent, uncontrollable, & free-floating anxiety 2. Panic Disorder: sudden & inexplicable panic attacks Anxiety Disorders (Continued) 3. Phobia: intense, irrational fear & avoidance of a specific object or situation Anxiety Disorders (Continued) 4. Obsessive-Compulsive Disorder (OCD): intrusive, repetitive, fearful thoughts (obsessions), with urges to perform repetitive, ritualistic, behaviors (compulsions), or both 5. Posttraumatic Stress Disorder (PTSD): anxiety disorder following extraordinary stress (discussed in Chapter 3) Explanations of Anxiety Disorders Psychological--faulty cognitions, maladaptive learning Biological--evolution, genetics, brain functioning, biochemistry Sociocultural—environmental stressors, cultural socialization Anxiety Disorders (Continued) Mood Disorders Mood Disorders: characterized by extreme disturbances in emotional states Two Main Types of Mood Disorders: • Major Depressive Disorder: long-lasting depressed mood that interferes with the ability to function, feel pleasure, or maintain interest in life • Bipolar Disorder: repeated episodes of mania & depression Mood Disorders (Continued) Note how major depressive disorders differ from bipolar disorders on this hypothetical graph. Explanations of Mood Disorders Biological--brain functioning, neurotransmitter imbalances, genetics, evolution Psychosocial--environmental stressors, disturbed interpersonal relationships, faulty thinking, poor selfconcept, learned helplessness, faulty attributions Mood Disorders (Continued) Gender & Cultural Diversity: Culture-general symptoms for depression (e.g., sad affect, lack of energy) Women more often depressed. Why? Combination of biological, psychological, & social forces (biopsychosocial model) Biological Social Psychological Schizophrenia Schizophrenia: group of psychotic disorders, characterized by a general loss of contact with reality Five areas of major disturbance: Perception (hallucinations) Language (word salad, neologisms) Thoughts (psychosis, delusions) Emotion (exaggerated or flat affect) Behavior [unusual actions (e.g., catalepsy, waxy flexibility)] 1. 2. 3. 4. 5. Subtypes of Schizophrenia Schizophrenia (Continued) Explanations of Schizophrenia: Biological: genetic predisposition, disruptions in neurotransmitters, brain abnormalities Psychosocial: diathesis-stress model, disturbed family communication Genetics & Schizophrenia Disturbed Brain Activity in Schizophrenia Note the differing amounts of brain activity in the normal, schizophrenia, and depressed brains. (Warmer colors = more activity) Schizophrenia (Continued) Gender & Cultural Diversity: Numerous culturally general symptoms, but significant differences exist in: prevalence • form • onset • prognosis • Other Disorders Substance-related disorder (abuse of, or dependence on, a mood- or behavior-altering drug) Two general groups: Substance abuse (interferes with social or occupational functioning) Substance dependence (causes physical reactions, such as tolerance & withdrawal) Other Disorders: Substance-Related Disorder Other Disorders (Continued) People with substance-related disorders also commonly suffer other psychological disorders, a condition known as comorbidity. Other Disorders (Continued) Dissociative Disorders: splitting apart (disassociation) of experience from memory or consciousness Types of Dissociative Disorders: Dissociative Amnesia Dissociative Fugue Depersonalization Disorder Dissociative Identity Disorder (DID) Other Disorders (Continued) Best known dissociative disorder: Dissociative Identity Disorder (DID): presence of two or more distinct personality systems in the same person at different times (previously known as multiple personality disorder) Other Disorders (Continued) Personality Disorder: inflexible, maladaptive personality traits causing significant impairment of social & occupational functioning Two types of personality disorders: Antisocial Personality Disorder Borderline Personality Disorder (BPD) Other Disorders (Continued) Antisocial Personality Disorder: profound disregard for, & violation of, the rights of others Key Traits: egocentrism, lack of conscience, impulsive behavior, & superficial charm Other Disorders (Continued) Explanations of Antisocial Personality Disorder Biological: genetic predisposition, abnormal brain functioning • Psychological: abusive parenting, inappropriate modeling • Other Disorders (Continued) Borderline Personality Disorder (BPD): impulsivity & instability in mood, relationships, & self-image Explanations of BPD: Psychological--childhood history of neglect, emotional deprivation, abuse Biological--genetic inheritance, impaired brain functioning • •
