Chapter 10 - Psychological Disorders and Treatment

psychopathology

psychological or mental disorder

continuum

a spectrum [of behavior] ranging from mild to severe, infrequent to constant, controllable to uncontrollable, with no clear dividing line to indicate when normal becomes abnormal

psychological disorder

classification of pattern of behavior marked by personal distress and/or functional impairment

biopsychosocial approach

viewpoint that considers biological, psychological, and social factors to explain behavior

B = f (P + E + PE)

behavior is best understood as a function of things about the person (inside), things about the environment (outside), and the complex interaction of person and environment

classification

process of describing and categorizing [behavior]

epidemiology

study of the frequency and distribution of disorders within specific populations over a specified period of time

psychosis

loss of contact with reality marked by severe disturbances in thought, language, sensory perception, emotion regulation, and behavior

biological diathesis

predispositions arising from genetic and/or physiological mechanisms

diathesis-stress model

model that explains how psychological disorders can develop; a predisposition (vulnerability) and stress are both necessary elements

sociocultural factors

diatheses and stressors that originate from social and cultural norms, beliefs, and practices

mania

state of unrealistically happy mood, with overactivity, distractibility, racing thoughts, and little need for sleep

depression

an abnormally low mood state characterized by feelings of sadness, emptiness, hopelessness, and guilt

predispositions arising from genetic and/or physiological mechanisms

depression

an abnormally low mood state characterized by feelings of sadness, emptiness, hopelessness, and guilt

diathesis-stress model

model that explains how psychological disorders can develop; a predisposition (vulnerability) and stress are both necessary elements

continuum

a spectrum [of anxiety] ranging from mild to severe, infrequent to constant, controllable to uncontrollable, with no clear dividing line to indicate when normal becomes abnormal

pathological anxiety and fear

irrational, persistent, maladaptive, and uncontrollable, may strike without a specific threat and cause significant personal distress and functional impairment

diathesis-stress model

model that explains how psychological disorders can develop; a predisposition (vulnerability) and stress are both necessary elements

biomedical therapy

treatment approach that attempts to correct specific biological defects that are thought to contribute to psychopathology, in order to alleviate or prevent symptoms (often using drugs)

psychotherapy

treatment process during which a trained clinician interacts with a client to help her/him feel, think, and behave differently in order to alleviate or prevent distress

deviation from social norm

culturally different

personal distress

subjective state characterized by emotional pain and suffering

functional impairment

internal dysfunction

origin of psychological problem is within the person, not an expected response to an event

etiology

the origin or cause (of abnormal behavior)
