Q

Voncken et al.: Social performance deficits in SAD

A

Q

Voncken et al.: Interpretation and judgmental biases

A
  • The Interpretation and Judgmental Questionnaire (IJQ) was used to assess interpretation and judgmental biases in social and non-social events
  • Findings: Social phobic patients interpreted social events as more negative and judged social events as more threatening compared to the normal control group
  • No differences between the two groups in their ratings of non-social events
  • These results confirm the hypothesis that interpretation and judgmental biases in social phobia are content-specific

Q

The role of hyperventilation in Panic Disorder

A
  • Hyperventilation can produce the symptoms of panic attacks that are recognized as anxiety
  • Has been supported by studies using biological challenge tests
  • This evidence has given rise to suffocation alarm theories

Q

This evidence has given rise to suffocation alarm theories

Definition

air or by encouraging hyperventilation

16
Q

Suffocation alarm theories

Concept

A

Models of panic disorder in which a combination of increased CO² intake may activate an
oversensitive suffocation alarm system and give rise to the intense terror and anxiety experienced during a panic attack

17
Q

Role of noradrenergic overactivity in Panic Disorder

A
  • Disorder may be caused by overactivity in the noradrenergic neurotransmitter system
  • Patient with panic disorder are deficient in gamma-aminobutyric (GABA) neurons that inhibit noradrenergic activity (PET studies have supported this view)
18
Q

Role of classical conditioning in Panic Disorder

A
  • “Fear of fear”: Meaning when they detect any sign of a panic attack, they immediately become fearful of the
    possible consequences
  • Leading to interoceptive classical conditioning, with an internal cue (e.g. dizziness), became established as a CS
    predicting a panic attack (US). But it is a circular explanation
19
Q

Anxiety sensitivity

Definition

A

Fears of anxiety symptoms based on beliefs that such symptoms have harmful consequences (e.g.
that a rapid heartbeat predicts an impending heart attack)

20
Q

Role of anxiety sensitivity in Panic Disorder

A

Panic disorder sufferers become extremely anxious when they detect any cues that may be indicative of a panic
attack and this leads to a panic attacks, because they have developed anxiety sensitivity

21
Q

Catastrophic misinterpretation of bodily sensations

Definition

A

A feature of panic disorder where there is a cognitive bias towards accepting the more threatening interpretation of an individual’s own sensation

22
Q

Clark’s model of panic disorder

Concept

A

Perception of a threat triggers
apprehension and then bodily sensations associated with that apprehension are interpreted catastrophically. This causes further anxiety which feeds into a vicious cycle that triggers a full-blown panic
attack

23
Q

Khawaja et al.: Catastrophic cognitions in Panic Disorders and Agoraphobia

A
  • There is empirical support for the concept of catastrophic cognitions in panic disorder and agoraphobia
  • Patients frequently engage in thoughts of dramatic consequences, particularly during elevated anxiety
    and panic
  • Hypervigilance and selective attention are important aspects of the process of catastrophic misinterpretation
24
Q

Safety Behaviors

Definition

A

Activities deployed by sufferers of panic disorder as soon as they think they are having a panic attack, developed in the belief that this activity has saved them from a catastrophic outcome

25
Q

Role of safety behaviors in Panic Disorder

A

Might uphoald fears because people keep thinking the only reason
everything went well is because of their safety behavio

26
Q

Criteria for determining if Biological Challenge test are cognitively mediated (Clark et al.)

A
  1. Panic disorder patients tend to interpret bodily sensations as signs of impending physical or
    mental disorders more than other anxiety disorder patients or normal controls.
  2. Panic attacks induced by CO2 inhalation are accompanied by catastrophic cognitions like “I am
    going to die”
  3. Experimental manipulations of cognitive variables impact an individual’s panic during biological
    challenge tests
27
Q

Rapee et al.: Manipulating interpretations of CO2 inhalation effects via pre-challenge explanations

A
  • Detailed explanation group reported fewer catastrophic cognitions and less panic during inhalation compared to
    the minimal explanation group.
  • Social phobics showed low panic ratings, confirming CO2’s panic-inducing effect is specific to panic disorder
    patients
28
Q

Sanderson et al.: Manipulation of perceived control

A
  • Deceptively manipulated perceived control during a 20-min 5% CO2 inhalation in panic disorder patients (told them they could control the CO2 flow
  • Illusion of control group reported fewer catastrophic cognitions and less panic, despite not having actual control over CO2 flow
29
Q

Margraf et al.: Manipulating patients expectations

A
  • Investigated hyperventilation challenge test, manipulating patients’ expectations before the procedure.
  • Patients expecting a “biological panic attack test” reported more panic symptoms compared to those expecting a “fast-paced breathing task”
30
Q

Rapee et al.: Reassuring observer during BCT

A
  • Explored the impact of a reassuring observer during CO2 inhalation on panic disorder patients with agoraphobia
  • Manipulation of perceived safety levels did not effectively differentiate panic occurrence between groups
31
Q

Clark et al.: Emphazising normalcy of sensations in BCT

A
  • Investigated sodium lactate-induced panic by allocating panic disorder patients to different pre-infusion instructional sets
  • Experimental instructions emphasizing normalcy of sensations resulted in less reported anxiety and fewer instances of panic compared to control instructions
32
Q

The main cognitive mediators of BCT-induced panic attacks

A

Manipulating interpretation of sensation or perceived control affected panic response, while manipulating expected affect didn’t always influence panic frequency

33
Q

Clark & Wells model of cognitive deteminants of anxiety and rumination in SAD

A
  • Dysfunctional beliefs triggering fear of negative evaluation
  • Self-focused attention, anxiety responses, and disregarding
    contradictory social cues
  • Reliance on safety behaviors reinforcing social incompetence beliefs
  • Pre-event rumination on past failures and post-event rumination on negative self-perception
34
Q

Rapee & Heimberg’s model of cognitive deteminants of anxiety and rumination in SAD

A
  • Emphasis on positive appraisals and assumption of inherent criticism by others
  • Anticipating negative evaluation reinforcing negative self-image
  • Focus on the discrepancy between expected performance and perceived standards
35
Q

Hofmann’s model of cognitive deteminants of anxiety and rumination in SAD

A
  • Unrealistic social standards and poorly defined goals contributing to apprehension
  • Inward attention, negative self-image, anticipation of social mishap, and reliance on safety behaviors
  • Post-event rumination and heightened anxiety due to perceived discrepancies
36
Q

Post-event rumination

A

It occurs after a social situation and is characterized by consolidating negative impressions about oneself, negative memories, and assumptions about future social situations.

37
Q

Pre-Event rumination

A

Involves preoccupation with thoughts regarding past failures and predictions of poor performance before encountering a feared social situation

38
Q

Agoraphobia

Definition

A

A fear or anxiety of any place
where the sufferer does not feel safe or feels trapped, and is accompanied by a strong urge to escape to a safe place
