Chapter 9 (Biopsychosocial Model For Phobia) Flashcards
specific phobia
is an anxiety disorder that is characterised by marked fear about a specific object or situation leading to avoidance behaviours
phobia categories
- animal
-situational - natural environmental
- blood, injection, injury
- other (death, vomiting, clowns)
response to phobia
- F-F-F response triggered
- can take form in a panic attack, feeling of impending doom
- panic attacks has both psychological and physiological symptoms
psychological factors
CONTRIBUTING FACTORS
- classical and operant conditioning
- cognitive bias (memory bias, catastrophic thinking)
INTERVENTION
- CBT
- systematic desensitisation
biological factors
CONTRIBUTING FACTORS
- GABA neurotransmitter dysfunction
- role of stress response
- long-term potentiation
INTERVENTION
- short term GABA agonists
- breathing retraining
- exercise
social factors
CONTRIBUTING FACTORS
- specific environmental triggers
- stigma around treatment
INTERVENTION
- psychoeducation for supporters (challenging unrealistic thoughts, not encourage avoidance behaviours)
GABA dysfunction
- inhibitory neurotransmitter
- acts as a calming agent to reduce anxiety by slowing down neural transmission
- individuals with anxiety disorders may have GABA dysfunctions
role of the stress response
- people with phobia tend to activate stress response when not needed
- could be the result of other factors
long-term potentiation
- strengthening of regularly used neural connection
- fear responses strengthened by repeat activation
- more pathway is activated the stronger the response
- LTP likely to occur in the amygdala
biological interventions
target the workings of the body that contribute to the phobia
medication - benzodiazepine
- group of drugs that work to target GABA receptors
- increases GABA affects on the postsynaptic neurons
- can be highly addictive, not recommended for long term use
- known as GABA agonists
- usually first treatment option for phobias
breathing retraining
- people when experiencing a phobia tend to over breath
- respiration rate increases, can increase fear and anxiety
- excessive breathing can disrupt balance of oxygen and carbon dioxide in the bloodstream
exercise
- reduces anxiety by releasing endorphins
- provides distraction from the phobic stimulus
- copes with physical aspects (using up stress)
- increases tolerance to stress response
psychological contributing factors
we acquire and maintain phobias psychologically via behavioural and cognitive
behavioural models
phobias are learnt through experience, and could be from environmental consequences
