Document Summary
According to psychologists and psychiatrists, psychological disorders. Are marked by a clinically significant disturbance in an individual"s cognition, emotion regulation, or behavior (apa, 2013) Disturbed or dysfunctional thoughts, emotions, or behaviors are maladaptive. Medical model: the concept that diseases, in this case psychological disorders, have physical causes that can be diagnosed, treated, and, in most cases, cured, often through treatment in a hospital. The medical perspective has gained credibility from recent discoveries that genetically influenced abnormalities in brain structure and biochemistry contribute to many disorders. But psychological factors, such as chronic or traumatic stress, also play an important role. Psychologists who reject the sickness idea typically contend that all behavior arises from the interaction of nature (genetic and physiological factors) and nurture (past and present experiences). The biopsychosocial approach assumes that disorders are influenced by genetic predispositions, physiological states, inner psychological dynamics, and social and cultural circumstances.
