2. anxiety Flashcards
Achenbach’s model relating to anxiety disorder
3 groupings of disorders (internalising, neither, externalising)
- said that anxiety disorder is under internalising disorder.
- also said that anxiety and depression work together and are almost the same thing
- shared key features of depression and anxiety in children (eg: irritability)
McNaughton & Corr’s model of anxiety disorder (flight, freeze, fight approach)
also known as traditional ‘basic animal’ model –> how animals cope and response to threat to environment
what do you do? fight, flight or freeze?
what is the freeze approach?
response/behaviour to something that is not expected
eg: when you were asked by someone to marry him… you’ll freeze
what is the approach-avoidance conflict?
you feel equally motivated to approach and avoid a threat.
eg: you’re at a party, you wanna go and talk to someone but you are both really wanna do it but also too terrified. so you’re stuck in both.
under McNaughton & Corr’s model of anxiety disorder, what is phobia classified as?
avoidance behaviour from the avoidable stuff
eg: you have snake phobia, you just avoid the high-snake-risk places
what is avoidance behaviour? what anxiety disorders are classified as avoidance behaviour in McNaughton & Corr’s model
goal: individual try to avoid and escape something that is either AVOIDABLE (phobia - snack) or UNAVOIDABLE (panic - you might not know what might trigger the panic attack but it is unavoidable)
what is fear?
feelings that occur when source of harm is IMMEDIATE
what is anxiety?
feelings that occur when source of harm is UNCERTAIN or UNKNOWN or DISTANT (space wise / time wise)
different between fear and anxiety
fear is towards IMMEDIATE harm, anxiety is towards UNCERTAINTY, DISTANT
why people used think fear and anxiety are the same thing???
fear and anxiety roots from amygdala.
what is the role of BNST in processing harm?
BNST encodes the nature of uncertainty of threat
this lead to the changed belief that fear and anxiety are processed in the same brain area
where does conscious processing associated with threat or harm take place?
in the brain, most subjective experience is processed at the cortical medial wall (middle line of your brain)
what is the tripartite model of anxiety and depression?
- picture venn diagram shape
- anxiety and depression share a feature (negative affect)
- anxiety has unique feature: physiological arousal
- depression has unique feature: absence of positive affect
what characterises depression in tripartite model?
- anhedonia
- worthlessness
- rumination (past oriented)
- suicide ideation (but then again, the strongest predictor of suicide in depression is anxiety
what is the main key in negative affect (overlapping feature) in anxiety and depression
repetitive negative thought.
also, even though rumination is unique to depression and worry is unique to anxiety, both might fall under repetitive negative thought.
