15. Psychological Disorders Flashcards
DSM-5
Commonly used abbreviation for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, published by the American Psychiatric Association, which defines a wide variety of mental disorders and establishes criteria for diagnosing them.
psychological disorder
A disturbance in a person’s emotions, drives, thought processes, or behavior that (a) involves serious and relatively prolonged distress and/or impairment in ability to function, (b) is not simply a normal response to some event or set of events in the person’s environment, and (c) is not explainable as an effect of poverty, prejudice, or other social forces that prevent the person from behaving adaptively, nor as a deliberate decision to act in a way that is contrary to the norms of society.
reliability
Degree to which a measurement system produces similar results each time it is used with a particular subject or set of subjects under a particular set of conditions (p. 47). Regarding diagnoses of disorders, the degree to which different diagnosticians, all trained in the use of the diagnostic system, reach the same conclusions when they independently diagnose the same individuals.
validity
Degree to which a measurement system actually measures the characteristic that it is supposed to measure (p. 48). Regarding diagnoses of psychological disorders, the degree to which the disorders identified are clinically meaningful; that is, the degree to which the diagnostic labels predict real-world behaviors and treatment outcomes.
ADHD
Common acronym for attention-deficit/hyperactivity disorder, a frequently diagnosed disorder in children, characterized by impulsiveness and difficulties in focusing attention on tasks.
