Week 2 - Anxiety disorders Flashcards
________ is the immediate alarm reaction triggered by a perceived danger
Fear
Physiological changes in the human body that occur in response to a perceived
threat, including elevated heart
rate, metabolism, blood pressure,
breathing and muscle tension;
these changes prepare the body
for resisting or fleeing from the
source of threat.
fight or flight
response
__________ alarm is fear that occurs in
response to a direct danger, such as the impending attack of a wild animal
True
__________ alarms trigger fight or flight response in situations that do not
represent an immediate physical threat and represent a hallmark of anxiety disorders.
False
Amongst Australian adults aged 16–85 years, _______ % will experience a mental disorder in their lifetime, with __________ disorders being the most common.
45
anxiety
The triple vulnerability includes:
_________ factors, _________ psychological factors and ___________ psychological factors.
biological
generalised
specific
triple vulnerability
Biological vulnerability is a ___________ predisposition of an individual to anxiety and depressive disorders.
genetic
The clustering of emotional disorders around a common genetic vulnerability has been called
‘the ________ ________ syndrome’.
general neurotic
Generalised psychological vulnerability includes beliefs that the
world is generally a dangerous place combined with broad expectations that events are beyond one’s
control. True/False
True
For example, early life experiences of stress and loss have been found to foster a sense within
the individual that s/he has minimal control over life events
Specific psychological vulnerability can be acquired through _____________ (pairing of a conditioned stimulus and aversive event such as being bitten by a dog), and includes factors that are specific to particular objects or situations that influence the expectation of a
negative outcome when confronted with a specific object or event.
conditioning
The relief from anxiety caused by escape and avoidance would increase the
probability that future avoidance would occur through the process of ___________ reinforcement.
negative
(the behaviours of escape and avoidance have been negatively reinforced (i.e., rewarded) as a
result of the reduction in anxiety)
Indirect pathways of conditioning include
_____________and ___________ acquisition.
- information (verbal
transmission of danger-related information from others, e.g. wolf is dangerous or overprotective parenting) - vicarious (acquired through observing others reacting to fear).
- Negative affectivity is subjective distress involving anxiety, disgust
and anger. - Positive affectivity involves feeling enthusiastic, active and alert. Therefore, low positive affectivity describes feelings of sadness and lethargy. These dimensions appear important in identifying
factors that are shared across the anxiety disorders as well as those that are unique.
According to DSM 5, anxiety disorders include: specific phobia, panic disorder, agoraphobia, social anxiety disorder and generalised anxiety disorder. True/False
True
Persistent fear in response to the presence or
anticipation of a specific object or situation, ________ phobia.
specific
Recurrent unexpected panic attacks.
Panic disorder
Anxiety about being in situations in which escape might be
difficult or help may not be available (e.g., public transport,
open spaces, enclosed spaces, crowds, outside home alone).
Agoraphobia
Fear of social situations where the person is exposed
to possible scrutiny by others (e.g., social interactions, being
observed, performing).
Social anxiety disorder
(social phobia)
Excessive anxiety and worry about a number of events or
activities.
Generalised anxiety disorder (GAD)
According to ICD-10,
specific phobias, agoraphobia
and social phobia are considered _________
anxiety disorders and described as those where the anxiety is evoked predominantly in specific situations.
phobic
(e.g. someone with social phobia feels extreme
anxiety only when in social situations, and someone with a dog phobia feels extreme anxiety only
when encountering a dog)
According to the DSM-5 the major feature of a specific phobia are three types of fear that must be out of proportion to the actual danger of the object or situation with respect to the person’s culture.
- intense fear
- consistent fear (almost every time the trigger is encountered) and
- persistent fear (over a period of at least six
months)
4 subtypes of specific phobia are fear of:
- animal
- natural environment (heights, storms and water)
- blood, injection and injury
- situational phobia (e.g., planes, elevators and enclosed places).
Most specific phobias begin in ___________and early ___________. The typical age of onset varies across
the different phobias. For instance, claustrophobia tends to develop after adolescence, whereas animal
phobias develop at about t
childhood, adolescence
The prevalence of phobias is greater among children than among adults, and as
children mature, many phobias tend to remit without treatment. True/False
True
The estimated lifetime prevalence of specific phobias
is ___-____ per cent, with a female-to-male ratio of 2:1.
Less than _____ per cent of individuals with
a specific phobia seek treatment, even though, in adults, phobias tend to be chronic if untreated.
7-9
1
Conditioning and _________ (information or vicarious transmission) learning pathways are likely to be involved in the development of specific phobias.
indirect
According to Seligman, theory of prepared classical
conditioning
has prepared people
to be easily
conditioned to
fear objects or
situations that
were dangerous
in prehistoric
times. True/False
True
Specific phobias are true/false alarms?
False
Behavioural
technique in
which the client
confronts the
feared stimuli that was avoided to reduce anxiety?
exposure therapy
Technique
of behaviour
therapy in
which clients
confront their
feared objects/
situations in real
life (as opposed
to imaginal
exposure).
in vivo exposure
Behavioural
technique in
which the client
is intensively
exposed to a
feared object
until anxiety
diminishes.
flooding
since the highly anxiety-provoking nature of flooding may not be acceptable to individuals, exposure therapy
usually goes from the least to the most feared objects and situations)
Elimination of
a classically
conditioned
response in which the conditioned fear response gradually decrease.
extinction
Lessening of
an organism’s
response with
repetition of the
stimulus.
habituation
Learning that
occurs when
new associations
between
conditioned
stimuli (CS) and
unconditioned
stimuli (US) are
developed during
exposure therapy.
The original
associations
between the CS
and US are not
erased.
inhibitory
learning
Person’s belief
that s/he has the
ability to succeed
in a specific
situation.
self-efficacy
Episode
during which
an individual
experiences a
rapid increase in
the physiological
and cognitive
symptoms of
intense fear and
discomfort.
panic attack
________ disorder is diagnosed when the sufferer is plagued by recurrent
unexpected panic attacks, with at least one month of
1. persistent concern or worry about additional panic attacks or their consequences (e.g., risk of heart attack) or
- significant changes in behaviour related to the attack (e.g., avoiding any exercise because it may
increase heart rate)
Panic
Current DSM describes diagnoses of ‘panic disorder with agoraphobia’ or ‘panic disorder without agoraphobia’? True/False
False
(current DSM describes them as separate diagnoses)
______________ is
diagnosed when the sufferer experiences fear or anxiety about at least two of the following five
situations with avoidance behaviours lasting at least _______ months:
(1) using public transport (e.g. buses, trains)
(2) being in open spaces (e.g. car park)
(3) being in enclosed spaces (e.g. cinemas)
(4) standing in queues or being in a
crowd, and
(5) being outside of home alone.
Agoraphobia
six
The median ages of onset are 30 years for panic, and 22 years for agoraphobia.
As with most other anxiety disorders, panic disorder occurs somewhat more often among females
with the proportion of females to males increasing as the severity of agoraphobia increases. True/False
True

Type of psychological
treatment that
combines both
cognitive and
behavioural
concepts and
techniques.
cognitive
behaviour
therapy (CBT)
The emphasis of exposure task is less on anxiety reduction and more on proving the individuals expectations of the situation wrong (e.g., ‘If I travel
on a bus, I will panic and I will have to jump off or I will go crazy’). True/False
True
Behavioural
technique used for internal phobic avoidance such as fear of bodily sensations that may signal panic attack.
interoceptive

The fear of panic can also be addressed with cognitive techniques such as _____________ that aim to change the false
beliefs a person has about panic and its sensations.
Psychoeducation
(usually the first step in effective treatments)
In addition to common flight or fight sensations, the most troubling sensations that
are visible to others such as sweating, blushing, shaking and fear of negative
evaluation from others is associated with _________ phobia/anxiety.
