CH 3 Flashcards
Etiology
causal pattern of abnormal behavior ( ALL ABOUT CAUSES)
Necessary cause
characteristic (X) that must exist for a disorder (Y) to occur
Sufficient cause
condition that guarantees the occurrence of a disorder; if X occurs, then Y will also occur
Contributory cause
: increases the probability of a disorder developing but is neither necessary nor sufficient for the disorder to occur
Diathesis-stress models
: describe mental disorders that develop when someone with a preexisting vulnerability for the disorder experiences a major stressor
Diathesis
: vulnerability; a predisposition toward developing a disorder that can derive from biological, psychological, or sociocultural causal factors
**Results from one or more relatively distal necessary or contributory causes but is generally not sufficient to cause the disorder
Stress
: response of individual to taxing demands
Correlate:
a variable (X) that is associated with an outcome of interest (Y)
Risk factor
a factor or characteristic that is associated with an increased risk of developing condition Y
Variable risk factors:
risk factors that can be changed
Fixed markers:
risk factors that cannot be changed
Variable marker:
if changing X does not lead to a change in Y, X is a variable marker of Y
Causal risk factor
: if changing X does lead to a change in Y, X may be a causal risk factor for Y
Distal risk factors
occur early in life but dont show effects for many years
Proximal
Shortly before occurence of symptoms
Reinforcing contributory cause
condition that reinforces/maintains maladaptive behvaior that is alr occuring
Risk factors and causes of abnormal behavior
Diathesis Stress Models: describe mental disorders that develop when a preexisitng vulnerability for the disorder experiences a major stressor
Diathesis: vulnerability, a predispotion toward developing a disorder that can derive from biological, psychological, or sociocultural causal factors
Stress: Response of individual to taxing demands
Developmental psychopathology
concentrates on determining what is abnormal at any point in development, by comparing and contrasting it with the normal and expected changes that occur in the course of development
Perspectives to Understanding the Causes of Abnormal Behavior
Several competing explanations are often offered for the same behavior
Biological, psychological, and sociocultural perspectives are three examples
Biopsychosocial viewpoint acknowledges that biological, psychological, and social factors all interact and play a role in psychopathology and treatment
Cultural context in which each of these factors plays out also influences how we think about behavior, both normal and abnormal
Genes (genetic vulnerability)
very long molecules of D N A present at various locations on chromosomes
Chromosomes (Genetic Vulnerabilty)
the chain-like structures within a cell nucleus that contain the genes
(Every 1 has 23 paris of chromosomes (46 in total)
Abnormalities in the structure or number of chromosomes can be associated with major defects or disorders
