Q

What is the major psychological approach for OCD, BDD, and hoarding disorder?

A

exposure and response prevention (ERP)

23
Q

Why is some caution warranted when treating OCD with SSRIs?

A

SSRIs require more time and higher doses to treat OCD (compared w/ depression)

24
Q

Why is caution warranted when treating hoarding disorder with antidepressant treatment?

A

-much research focuses on hoarding symptoms among OCD patients

25
Q

What is exposure and response prevention (ERP)?

A

sufferer is prevented from engaging in compulsive ritual activity and instead faces the anxiety provoked by the stimulus - leads to eventual extinction of the conditioned response (anxiety)

26
Q

What is the reasoning behind exposure and response prevention (ERP)?

A
  1. not performing the ritual exposes the person to the full force of the anxiety provoked by the stimulus
  2. the exposure promotes the extinction of the conditioned response (the anxiety)
27
Q

What does the exposure element of ERP focus on for those w/ hoarding disorder?

A

getting rid of their objects

28
Q

What is deep brain stimulation?

A

used for OCD patients who do not respond to medication - involves implanting electrodes into the brain (one of several regions of basal ganglia)

29
Q

How do trauma-related diagnoses differ from other major DSM diagnoses?

A

only diagnosed when a person develops symptoms after a traumatic event

30
Q

What is posttraumatic stress disorder (PTSD)?

A

an anxiety disorder in which a particularly stressful event, such as military combat, rape, or a natural disaster, brings in its aftermath intrusive re experiencing of the trauma, a desire to avoid reminders of the event, changes in emotions and thought patterns, and indicators of heightened arousal

  • avoidance of stimuli associated w/ the event
  • other signs of negative mood and thought that developed post trauma
  • symptoms of increased arousal and reactivity
35
Q

What is acute stress disorder (ASD)?

A

a short-lived anxiety reaction to a traumatic event; if it lasts more than a month, it is diagnosed as posttraumatic stress disorder

36
Q

What are two major concerns about the ASD diagnosis?

A
  1. the diagnosis could stigmatize very common short-term reactions to serious traumas
  2. the diagnosis of ASD is not very predictive of who will develop PTSD
37
Q

What proportion of people who develop ASD will develop PTSD within 2 years?

A

less than half

38
Q

What are some benefits to an ASD diagnosis?

A

may encourage providers to identify people who could use more support after a trauma

39
Q

What percentage of people who developed PTSD by age 26 had been diagnosed w/ another psychological disorder before age 21?

A

93%

40
Q

What fraction of people who develop PTSD have a history of anxiety disorders?

A

2/3

41
Q

What percentage of American fighters wounded in Vietnam developed PTSD?

20%

42
Q

What percent of prisoners of war in Vietnam developed PTSD?

A

heightened activity in hippocampus

45
Q

What is dissociation?

A

a symptom in which a group of mental processes is split off from consciousness

46
Q

What are some factors that affect how likely someone will develop/recover from PTSD?

A
  • dissociation (higher dissociation, more likely to develop PTSD)
  • social support
  • intelligence (to make sense of horrifying events)
47
Q

How is trauma beneficial to some people?

A

awakens an increased appreciation of life, renews a focus on life priorities, and provides an opportunity to understand one’s strengths in overcoming adversity

48
Q

What is the primary psychological approach to treating PTSD?

A

exposure treatment

49
Q

What is eye movement desensitization and reprocessing (EMDR)?

A

approach to PTSD in which client recalls a scene and visually tracks therapist’s fingers

A

claims that the eye movement component isn’t necessary (just regular old exposure)

51
Q

What is imaginal exposure?

A

treatment for anxiety disorders that involves visualizing feared scenes for extended periods of time (esp when in vivo exposure can’t be conducted)

52
Q
