Document Summary
Introduction: enormous heterogeneity of psychopathology makes a formal system of organization imperative (dsm-5, icd-10) Antisocial personality disorder: disorders are syndromes that cannot be readily explained by other conditions, ex. Ocd can only be diagnosed if its symptoms and signs cannot be accounted for by a specific phobia: diseases are disorders in which pathology and etiology are reasonably well understood, ex. Sickle-cell anemia: alzheimer"s pathology is known while their etiology is unknown, the diagnosis in current psychiatric classifications are almost all syndromes or in rare cases, disorders. In this respect, a psychiatric diagnosis is no different from medical diagnosis. Internal consistency- the extent to which the signs and symptoms comprising a diagnosis hang together (correlate together: assessed using metrics such as coefficient alpha or the mean inter-item correlation. Interrater reliability- the degree to which two or more observers agree on the diagnosis of a set of individuals. Misconception #5: psychiatric diagnoses stigmatize people, and often result in self-fulfilling.
