Demonic Model: View of mental illness in which odd behavior, hearing voices, or talking to oneself was attributed to evil spirits infesting the body

Question 2

Renaissance (14th-17th Centuries)

Governmental policy in the 1960s and 1970s that focused on releasing hospitalized psychiatric patients into the community and closing mental hospitals.

Question 6

Statistical Rarity

Answer 6

Cannot rely on statistical rarity to define mental disorder because not all infrequent conditions are pathological (caused by physical/mental disease)

Question 7

Subjective Distress

Answer 7

Most mental disorders, including mood and anxiety disorders, produce emotional pain for individuals afflicted with them. But not all psychological disorders generate distress.

Question 8

Impairment

Answer 8

Most mental disorders interfere with people’s ability to function in everyday life (hurt relationships and jobs). Yet the presence of impairment by itself can’t define mental illness because some conditions, like laziness, can produce impairment but aren’t mental disorders.

Question 9

Biological Dysfunction

Answer 9

Mental Disorders probably result from breakdowns or failures of physiological systems.
Mental disorders, appear to be acquired largely through learning experiences and often require only a weak genetic predisposition to trigger them.

Question 10

DSM-5-TR: Definition of a Mental Disorder

Answer 10

2.The consequences of which are clinically significant distress or disability - Distress: Painful symptom; Disability: Impairment in one or more important areas of functioning.
3.Must not be merely an expectable response to common stressors or culturally sanctioned response to an event.
4.Reflects an underlying psychological or mental dysfunction
5.Not solely a result of social deviance or conflict with society, unless it results in individual dysfunction.
6.Has diagnostic validity using one or more sets of diagnostic validators. - Prognostic significance, psychobiological disruption, and response to treatment.
7.Has clinical utility - Contributes to better conceptualization of diagnoses, or to better assessment and treatment

Question 11

Psychiatric diagnoses serve at least two crucial functions

Answer 16

Question 76

Possible explanations for DID Posttraumatic model

a history of childhood abuse leads individuals to "compartmentalize" their identity into alters as a means of coping with intense pain. researchers have not shown that early abuse is specific to DID, as it is present in many other disorders
