ANSWERS
Question 1:
From day #95
Answer: d
Exposure and Response Prevention Therapy (ERP) is a first-line therapy for OCD.
Explanation:
Exposure and Response Prevention Therapy (ERP) 1
ERP is a specialized form of CBT and is first-line psychotherapy for mild/moderate OCD with minimal co-morbidities.
As the name implies, it includes repeated and prolonged exposures to the thoughts, images, objects, and situations that make them anxious and/or start obsessions. It also includes response prevention training in order to help them not perform compulsive behaviors.
Sessions typically occur weekly and have weekly homework assignments.
Results vary, but randomized control trials have shown improvement in 55-85% of patients and improvement is maintained after completion of treatment.
If poor response after course of ERP alone then add pharmacotherapy.
Wrong Answers
Prolonged Exposure (PE): evidence based treatment for PTSD.
Psychodynamic Therapy: evidence based for many conditions, however no rigorous evidence that a psychodynamic approach is useful in the treatment of OCD. 2
Stimulus Control: one aspect of cognitive behavioral therapy for insomnia (CBT-i).
Question 2:
From day #96
Answer: b
With muscle dysphoria
Explanation:
There are two specifiers for body dysmorphic disorder.
1) level of insight regarding their beliefs (good or fair; poor; absent/dellusional)
2) if they have muscle dysmorphia (belief that their body is too small or insufficiently muscular).
Question 3:
From day #98
Answer: b
12 years old
Explanation 3:
Trichotillomania (Hair-Pulling Disorder)
Lifetime prevalence 1-2% of the adult population. More common in woman than in men (10:1 ratio).
In women, the most common age of onset is near menarche. Keep in mind that some studies suggest that non-cosmetic hair-pulling occurs in greater than 10% of college students, however only 1-3% meet criteria for trichotillomania.
Excoriation (Skin-Picking Disorder)
Lifetime prevalence 1.5-3.5% of the adult population. There is variability among studies regarding gender prevalence, but most estimate that >75% of diagnoses are women.
Mean age of onset is 12 years old, typically coinciding with the onset of puberty.
