Question 3

Prevalence of SAD

Answer 3

• Between 4-13% in Western societies, but rates are significantly lower in South-East Asian countries
• A gender prevalence of 3:2 females to males

Question 4

Genetic Factors of SAD

Answer 4

Constructs related to SAD that have a genetic component are:
* Submissiveness
* Anxiousness
* Social Avoidance
* Behavioral Inhibition

Question 5

Behavioral inhibition

Definition

Answer 5

A construct used to define the characteristics in some children of seeming quiet, isolated and anxious when confronted either with social situations or with novelty

Question 6

Familial and developmental factors of SAD

Answer 6

Parents of children with social anxiety disorder:
* Exert greater control over their children
* Show less warmth
* Are less sociable
* Use shame as a method for discipline

Question 7

Cognitive factors of SAD

Answer 7

• Information processing and interpretation biases
• Overcritical evaluation of their performance in social situations
• Self-focused attention
• Excessive post-event processing

Question 8

Voncken et al.: Social performance deficits in SAD

Answer 8

• Involved two tasks: a speech and a conversation, which were randomly assigned to participants
• Findings: Found that patients with SAD were characterized by both biased estimations and social performance deficits

Question 9

Voncken et al.: Interpretation and judgmental biases

Answer 9

• 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

Question 10

Attention Bias Modification

Answer 10

A therapy for SAD
* Attentional biases toward threatening information are addressed through computer-based ABMT, aiming to redirect attention away from socially threatening stimuli.
* Debate about its viability as a treatment

Question 11

Panic disorder

Definition

Answer 11

An anxiety disorder characterized by repeated panic or anxiety attacks

Question 12

Panic attack

Definition

Answer 12

An abrupt surge of intense fear or discomfort in which four or more of a list of symptoms (DSM-5) develop suddenly

Question 13

DSM-5 Criteria for Panic Disorder

Answer 13

A. Recurrent unexpected panic attacks
B. At least one of the attacks has been followed by 1 month or more of persistent concern about additional panic attacks or maladaptive change iin behavio to avoid panicking
C. Not attributable to substances or medical condition or D. Another mental disorder

Question 14

The role of hyperventilation in Panic Disorder

Answer 14

• 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

Question 15

This evidence has given rise to suffocation alarm theories

Definition

Answer 15

Research in which panic attacks are induced by administering carbon dioxide (CO²) enriched
air or by encouraging hyperventilation

Question 16

Suffocation alarm theories

Concept

Answer 16

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

Question 17

Role of noradrenergic overactivity in Panic Disorder

Answer 17

• 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)

Question 18

Role of classical conditioning in Panic Disorder

Answer 18

• “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

Question 19

Anxiety sensitivity

Definition

Answer 19

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

Question 20

Role of anxiety sensitivity in Panic Disorder

Answer 20

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

Question 21

Catastrophic misinterpretation of bodily sensations

Definition

Answer 21

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

Question 22

Clark’s model of panic disorder

Concept

Answer 22

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

Question 23

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

Answer 23

• 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

Question 24

Safety Behaviors

Definition

Answer 24

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

Question 25

Role of safety behaviors in Panic Disorder

Answer 25

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

Question 26

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

Answer 26

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

Question 27

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

Answer 27

* 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

Question 28

**Sanderson et al.:** Manipulation of perceived control

Answer 28

* 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

Question 29

**Margraf et al.:** Manipulating patients expectations

Answer 29

* 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”

Question 30

**Rapee et al.:** Reassuring observer during BCT

Answer 30

* 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

Question 31

**Clark et al.:** Emphazising normalcy of sensations in BCT

Answer 31

* 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

Question 32

The main cognitive mediators of BCT-induced panic attacks

Answer 32

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

Question 33

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

Answer 33

* 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

Question 34

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

Answer 34

* 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

Question 35

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

Answer 35

* 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

Question 36

Post-event rumination

Answer 36

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

Question 37

Pre-Event rumination

Answer 37

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

Question 38

Agoraphobia | Definition

Answer 38

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
