Approaches to Psychological
Disorders

Biological model: Disorders have a biochemical or physiological
basis.

Psychoanalytic model: Disorders result from unconscious internal
conflicts.

Cognitive-behavioral model: Disorders result from learning
maladaptive ways of thinking and behaving.


Diathesis-stress model: People biologically predisposed to a mental
disorder (diathesis) will tend to exhibit that disorder when particularly
affected by stress.
Systems approach: Biological, psychological, and social risk factors
combine to produce disorders.
Psychological Disorders
“For what is it that constitutes a ‘disease entity’ or a ‘new disease’? The
physician is concerned not, like the naturalist, with a wide range of
different organisms theoretically adapted in an average way to an
average environment, but with a single organism, the human
subject, striving to preserve its identity in adverse circumstances.”
—Ivy McKenzie
“By the deficits, we may know the talents, by the exceptions, we may
discern the rules, by studying pathology we may construct a model
of health. And—most important—from this model may evolve that
insights and tools we need to affect our own lives, mold our own
destinies, change ourselves and our society in ways that, as yet, we
can only imagine.”
—Laurence Miller
