PSY240 3. Anxiety Flashcards
Anxiety
Negative affect
– Somatic symptoms of tension
– Apprehensive anticipation of future danger
Anxiety
- anxiety: worrying about something that hasn’t come
e. g. muscle tension
fear: present reaction to threat
normative emotions
Anxiety
-
Fear
Immediate alarm reaction to present danger
– “fight or flight”
Fear
-
Adaptive versus Maladaptive Fear
FEAR
Adaptive ===> Maladaptive
Adaptive versus Maladaptive Fear
realistic concerns => unrealistic concerns
e.g. concern is unfounded - unlikely to happen
proportional => disproportional
the amount of fear experience
excessive distress
subsides upon removal of threat => persists after threat also anticipatory anxiety
worked up agitated state of anticipation
incontrollable and helpless
impairing functioning

Anxiety Disorders
Commonalities
• Basic biological causes
• Basic psychological causes
• Effective treatments
Anxiety Disorders
we all experience it and have similar concerns
same commonalities in DSMV disorders
similar causes and treatments
treatments: behavioural treatments
Anxiety Disorders
-
Anxiety Disorders
-
Anxiety Disorders
- Severe
- Impact quality of life
- Chronicity and frequency
- Interfere with functioning
- Disproportion to real dangers
Anxiety Disorders
not everyone has it - beyond normal experiences
severe: affects life + enjoyment
far more frequent and pervasive
becomes an obstacle: e.g. can’t leave house anymore

Panic Attacks (PAs)
- Not a disorder
- Intense fear/discomfort
- Sudden onset and peaks rapidly (
Panic Attacks (PAs)
-symptoms: sweating, heart rate, muscle tension
cued: suddenly in response to specific stimulus
uncued: out of the blue
suddenly develop all of these symptoms at once
Panic Attacks (PAs)

Panic Disorder (PD)
• Recurrent, unexpected panic attacks (PAs)
• Followed by 1+ month of (at least one): – Persistent concern about having another PA
– Persistent concern about implications of PAs – Significant change in behaviour
Panic Disorder (PD)
important for diagnosing panic disorder: only when there’s at least 2 uncued panic attacks
at least 1 month or longer after - constant fear of having another attack and/or the implications of having a heart attack
change in behaviour: e.g. stop riding the subway because it happened there last time - can’t go to work
uncued becomes cued - come to fear that situation or place - would still be diagnosed as PD
Panic Disorder (PD)
-
Panic Disorder (PD)
-
Agoraphobia
- Anxiety about places / situations where escape might be difficult or help is unavailable
- Situations avoided or endured with distress
Agoraphobia
-condition in itself
fear of wide open space
50% of PD also have agoraphobia
might be able to do it if they had someone with them
Agoraphobia
-
Examples of Agoraphobia
e.g. fear of crowds, lines, on trains, on a bridge, being in a house alone or leaving house alone
Examples of Agoraphobia
-
Separation Anxiety Disorder
Excessive anxiety concerning separation from the home or primary caregiver(s)
previously in developmental disorder => now anxiety disorder
physical symptoms: being sick - can’t go to school
complain so they can stay - can be real
frequent nightmares of separation
Separation Anxiety Disorder
4+ weeks (6 mos in adults): avoid over-pathologizing responses to transitions
Separation Anxiety Disorder
not a lot of evidence of continuity - maybe it doesn’t continue or a measurement artifact
e.g. earlier in life, parent interview, later in life, self-report
generally when child first goes to school
can come up later in life - can’t recall disorder
Separation Anxiety Disorder
e.g. going to college
e.g. over concern of offspring or spouse
we don’t know as much about condition in adulthood
Selective Mutism (DSM-5)
- Consistent failure to speak in social situations
- Interfereswithachievement
- Duration>1month
- Not due to lack of knowledge of language
- Not better accounted for by other disorders
Selective Mutism (DSM-5)
emerges in childhood - likely to manifest in school age
don’t know much about longitudinal course of disorder
rule out other possibilities such as developmental disorder, difficulty in interaction due to anxiety or language problems

Specific Phobia
- Marked and persistent fear
- Exposure almost invariably provokes fear/anxiety* • Situation avoided / endured with distress
- Fear/anxiety ≠ actual danger posed
Specific Phobia
cannot under any circumstance endure situation or stimulus
intense amount of distress
in childhood: fear may be expressed through screaming, not speaking, tantrums
similar symptoms, but tied to specific stimulus or situation

Social Anxiety Disorder (Social Phobia)
Fear of being focus of attention/scrutiny
• Fear of being humiliated
– Capacity for age-appropriate relationships* – Must occur in peer settings*
• Exposure almost invariably provokes anxiety • Fear is persistent (6+ months)
Social Anxiety Disorder (Social Phobia)
specific social situations that evoke fear
common
20% of US college students report fear of public speaking
wording change in DSM-V
fearful of humiliation
early on - other disorders may cause symptoms like Autism
anxiety must be occurring not just with adults, but with peers
primary concern to be judged as stupid or weak
significant impairment: e.g. run out of room screaming during a presentation

Generalized Anxiety Disorder (GAD)
Chronic/exaggerated worry / tension (6+ mos) • Unable to control worry • Physical symptoms (3+)* – Restlessness, keyed up, on edge – Easily fatigued – Difficulty concentrating – Irritability – Muscle tension – Sleep disturbance
Generalized Anxiety Disorder (GAD)
worries about a lot of things
feel like you can’t control the worry
in adults at least 3, in kids (

Epidemiology
Disorder l Age of Onset l Prevalence l Gender
Separation Anxiety l ~ preschool l 0.9%–4.0% l F>M
Selective Mutism l M
Social Anxiety l 8 – 15 years l 7.0–12.0% l F>M
Agoraphobia l 17 years l 1.7% l F>M
Panic Disorder l 20 – 24 years l 2.0–3.0% l F>M
Generalized Anxiety l M
Epidemiology
-some disorders such as social anxiety are more common, while mutism is rare because we are ruling it out
anxiety disorders more common in female
manifestation may be different by gender
boys may show indirect symptom - e.g. boys say they have nightmares instead of I don’t wanna go to school
gender differences emerge depending on specific object of phobia
emerge most frequently in adolescents, but in youth may show remission later on
social phobia: males more often diagnosed with because it is inconsistent with expectations of masculinity

Comorbidity
- Anxiety and anxiety
* Anxiety and depression (i.e., internalizing) • Anxiety and substance use disorders
Comorbidity
-
Comorbidity
internalizing disorders
inwardly directed emotional problems
externalizing: violence, acting out, substance abuse
in children it’s less clear cut the difference between the two than in adults
social anxiety: e.g. have a drink to calm nerves
issue of self-medicate with alcohol
in most cases, anxiety comes first

Biological Approach: Structural Theories
Dual pathway model of fear
Stimulus => Thalamus => Amygdala
Biological Approach: Structural Theories
Stimulus => Thalamus => Cerebral Cortex
Biological Approach: Structural Theories
-understand how brain processes fear
get info from environment that triggers fear response
thalamus: gateway
amydala: registers danger, stores emotional memory
triggers fast reaction
cerebral cortex: to brain for more thoughtful processing of info
Biological Approach: Structural Theories

Biological Approach: Structural Theories
-
Biological Approach: Psychophysiological Theories
- Poorly regulated fight-or-flight responses
* Overreactive autonomic nervous system
Biological Approach: Psychophysiological Theories
-might be sensitive to bodily reactions when exposed to fear stimulus
same experience of hyperventilating can cause more intense reactions in other ppl
might be sensitively attuned to bodily reactions when exposed to fear stimulus
Biological Approach: Genetic Theories
twin studies: genetic transmission more frequent in families with probands of anxiety disorders range of heritability: PD - more narrow confidence intervals SAD - larger range across studies-
Biological Approach: Genetic Theories

Biological Approach: Genetic Theories
Molecular Genetics Studies
• Serotonergicsystem (5-HT;SLC6A4)
• Dopaminergicsystem (DRD4;DRD2)
• Modulation of monoamine metabolism (MAOA; COMT)
Biological Approach: Genetic Theories
-serotonergic: involves negative emotions
dopaminergic: excessive or lack of receptors through generations
degradation of serotonin
proposed to be related
proposed for candidate gene studies
due to expense - not enough replication
Biological Approach: Genetic Theories
-
Biological Approach: Genetic Theories
-
Biological Approach: Neurotransmitter Theories
Poor regulation of NTs – NE (stimulating)
– 5-HT (mood regulation)
– GABA (inhibitory)
• GAD: Deficiency of GABA or GABA receptors
Biological Approach: Neurotransmitter Theories
Norepinephrine - physiological hyperactivity in anxiety disorders
serotonin - insufficient may be implicate in anxiety disorders
GABA: calming effect - regulating emotion
insufficient not being able to habituate to novel stimuli
related to GAD - worrying about everything because we’re not getting used to them

Personality/Temperament Traits & Anxiety
• Neuroticism/Negative Affectivity (Kotov et al., 2010) • Behavioral inhibition (Kagan)
– Risk for social phobia
Personality/Temperament Traits & Anxiety
-more phenotypic, but influenced by heritable genes
high in neuroticism: more prone to anxiety disorder
tendency to display inhibition
high: more likely to be extremely inhibited in new situations
e.g. vulnerable to social phobia
Personality/Temperament Traits & Anxiety
-
Psychological Approach: Cognitive Theories
- High anxiety sensitivity
- Hyper-vigilant to potential threat
- Cognitive self-evaluation model (social phobia)
Psychological Approach: Cognitive Theories
attribution to physical symptoms
catastrophic interpretation of events
misinterpretation of events
people with extremely high standards in social performance situations
assume everyone will judge them harshly
sensitive to misinterpreting social judgement cues
Psychological Approach: Cognitive Theories
-
Triple Vulnerability Model
Biological Vulnerability
Heritable contribution to negative affect
Specific Psychological Vulnerability Catastrophic interpretations (e.g., of physical sensations)
Generalized Psychological Vulnerability External locus of control
Triple Vulnerability Model
possession of all three most at risk to developing a disorder
specific psychological vulnerability: maladaptive interpretations
Triple Vulnerability Model
-
Triple Vulnerability Model
-
Psychological Approach: Behavioural Theories
Acquired through classical conditioning – Can occur via observational learning
• Maintained through operant conditioning
Psychological Approach: Behavioural Theories
e. g. got stung by bee, conditioned to fear them
e. g. or seeing someone get stung by a bee
e. g. running away from bee, anxiety subsides so operantly conditioned to run away
Psychological Approach: Behavioural Theories
-
Psychological Approach: Behavioural Theories
-
Biological Treatments
Tricyclic antidepressants
Increase levels of NTs (e.g., norepinephrine)
Serotonin reuptake (SSRIs) Increase levels of serotonin
Benzodiazepines
Suppress CNS and influence NT functioning
▪ NE, 5-HT, and GABA systems
Biological Treatments
shown to work on certain anxieties
e.g. but don’t give tricyclic to PD, but maybe to GAD
improve regulation of negative disorders
increase GABA - inhibiting physiological responses
addictive, so not given as first treatment
Biological Treatments
-
Biological Treatments

Behavioural Treatments
- Modelling
- Flooding (aka Implosive Therapy)
- Systematic desensitization
Behavioural Treatments
most effective
modelling: therapist models appropriate reaction
flooding: exposing it all at once
e.g. sending them to a bee farm
not preferred approach
bodies can only sustain reaction for so long, then they realize that it’s not so bad
more gradual exposure
Behavioural Treatments
-
Behavioural Treatments
-
Systematic Desensitization
- Develop a fear hierarchy
Behavioural Strategies - Teach relaxation and breathing exercises
- Practice gradual exposure to feared situations
- Practice relaxation while experiencing panic symptoms
Cognitive Strategies
• Identify maladaptive cognitions
• Challenge catastrophizing thoughts
Systematic Desensitization
- least feared to most feared
- teach relaxation, only when they can perform it can they move on to gradual exposure
- start small so they can extinguish fear to smallest fear and show they can manage it
e.g. fear of spider bite, gradual exposure provides evidence that it’s not gonna kill them

What works for Anxiety?
• GAD:
– Treatment > No treatment (Cuijpers et al., 2014)
– Improve in short-term, but not at follow-up (Westen & Morrison, 2001) – Best results for CBT (Dugas et al., 2003)
• Panic:
– Improve and remain improved at follow-up (Westen & Morrison, 2001) – CBT = pharmacotherapy (Mitte, 2005)
What works for Anxiety?
attacking maladaptive thoughts and replacing them
gains are sustained
as effective as medication
cessation of medication, the symptoms return

Obsessive-Compulsive Disorder
Either obsessions OR compulsions
• Time-consuming (>1hr/day) • Cause distress/impairment
Obsessive-Compulsive Disorder
-has to interfere with functioning or distress

Obsessive-Compulsive Disorder
-
Obsessions (DSM-5)
• Recurrent and persistent thoughts, urges, or images
• Intrusive and unwanted, cause anxiety/distress
• Thoughts,impulses,orimagesthat:
– Are not simply excessive worries about real life problems – The person recognizes are a product of own mind
– The person attempts to ignore or suppress or to neutralize with some other thought or action
Obsessions (DSM-5)
thoughts of germs, killing someone, need for symmetry
reality testing
excessive - required that they realized it was out of proportion
with kids you don’t expect this insight
Obsessions (DSM-5)
-
Obsessions (DSM-5)
-
Compulsions (DSM-5)
• Repetitive behaviours or mental acts that the person feels driven to perform in response to an obsession or rigid rules
• Aimed at preventing/reducing distress or preventing some dreaded event or situation
– Unrealistic – Excessive
Compulsions (DSM-5)
-fit well with obsessions
e.g. entire elaborate ritual of handwashing
if not done right causes substantial anxiety
checking
counting up
cleaning or washing
doing things in order
ordering and organizing
neutralize obsessive thought

Biological Theories of OCD
• Brain dysfunction in areas that control primitive behaviour
• Linkedto5-HT
• Evidence for a genetic predisposition (Nestadt et al., 2010) – 7-15% in first-degree relatives of probands
– Limited knowledge of potential candidate genes
Biological Theories of OCD
-e.g. aggression and sex
serotonin function - linked to negative emotions
common within families with OCD
don’t know which genes
