Questions and Answers

A patient reports experiencing intense anxiety specifically when anticipating dental procedures involving injections, but remains relatively calm during other medical interventions. According to DSM-5 classifications, which specific phobia subtype most accurately describes this presentation, considering potential co-morbid anxieties?

Blood-injection-injury phobia, demonstrating a conditioned response specific to invasive procedures. (correct)
Other phobia, given the lack of direct trigger from blood or injury but the procedural anticipation.
Situational phobia, complicated by health anxiety related to medical environments.
Comorbid specific phobias, reflecting both situational anxiety and blood-injection-injury related apprehension.

A researcher posits that spontaneous panic attacks are primarily driven by fluctuations in the locus coeruleus's norepinephrine activity, independent of cognitive appraisals. Which experimental design would most rigorously test this hypothesis, isolating the neurological from the psychological?

Performing a double-blind, placebo-controlled trial of a selective norepinephrine reuptake inhibitor (SNRI) in patients with panic disorder and assessing frequency of uncued panic attacks. (correct)
Employing cognitive restructuring techniques to alter interpretations of physiological sensations during induced panic and measuring changes in norepinephrine metabolites.
Administering a beta-blocker to reduce physiological arousal during induced panic in a controlled environment and measuring subjective anxiety levels.
Using fMRI to correlate real-time locus coeruleus activity with self-reported anxiety levels during unpredictable cue exposure.

A patient with severe agoraphobia consistently avoids public transportation. Which cognitive-behavioral therapy (CBT) intervention would most directly address the core maladaptive belief maintaining this avoidance behavior, assuming catastrophic misinterpretations of somatic sensations?

Cognitive restructuring to challenge and modify catastrophic thoughts about the consequences of experiencing panic symptoms on public transportation. (correct)
In-vivo exposure to increasingly challenging public transportation scenarios, coupled with relaxation techniques to manage anxiety.
Interoceptive exposure exercises designed to simulate and habituate the feared somatic sensations associated with panic attacks.
Psychoeducation about the neurobiology of panic disorder to reduce the perceived threat of physiological symptoms.

Given the high comorbidity between specific phobias and other anxiety disorders, which assessment strategy would be most comprehensive in differentiating a primary specific phobia from a phobic avoidance behavior secondary to another underlying condition, such as social anxiety disorder or OCD?

Conducting a thorough differential diagnostic interview encompassing all DSM-5 anxiety disorders and related conditions, including functional impairment analysis. (B) Signup and view all the answers

In the context of DSM-5's classification of panic disorder and agoraphobia, how does the concept of 'situationally predisposed' panic attacks inform differential diagnosis and treatment planning, particularly when distinguishing between panic disorder with and without agoraphobia?

'Situationally predisposed' specifically signifies that the individual is more prone to experience panic attacks in certain situations but does not necessarily meet the full criteria for agoraphobia. (B) Signup and view all the answers
