50
What is the psychodynamic perspective of the aetiology of anxiety? (x3)
Caused by conflict between unconscious sexual/aggressive wishes/impulses, and corresponding threats from superego i.e. is signal that indicates impulse is about to be acted on – signal triggers defences (e.g. repression) to prevent recognition of impulse and reduce anxiety When impulse is too strong, anxiety overwhelms system = anxiety disorder
51
What is the evolutionary perspective of the aetiology of anxiety? (x2)
Anxiety evolved to enable protective behaviour to be activated - part of an adaptive system Anxiety disorders – problems in regulation of system
52
What biological factors are thought to contribute to the aetiology of anxiety? (x2)
Genetic predisposition | Neurobiology/neurotransmitters
53
What do twin studies reveal about genetic predispositions to anxiety? (x4)
Higher concordance rates MZ vs DZ twins (34 vs 17%) Anxiety disorders are modestly to moderately heritable, varying across disorders, ranging *Social phobia 24-51% to *Agoraphobia 61%
54
What role is neuroanatomy/chemistry posited to play in the aetiology of anxiety? (x4 and x1)
Animal studies show threat/danger pathways: *Subcortical for fight/flight *Slower one to cortex for more detailed info That are thought to play role - e.g. inappropriate triggering Serotonin & GABA dampen stress responses/reduce anxiety
55
Describe the biological model of OCDS (x2)
Higher activity in “cortical-striatal-thalamic” circuit (prefrontal cortex, thalamus, basal ganglia) *Area related to filtering out irrelevant information and repetition of behaviour
56
What social factors are generally associated with anxiety disorders? (x5)
``` Stressful life events Childhood adversity Parenting style Child temperament/behavioural inhibition Attachment relationships separation anxiety ```
57
What does the current psychosocial perspective hold to be psychological factors affecting the aetiology of anxiety? (x6)
Learning theory and processes * Classical conditioning (Little Albert) * Operant conditioning * Vicarious conditioning * Observational learning * Information transmission
58
How does classical conditioning explain the aetiology of anxiety? (x2)
Fear/phobias develop as result of pairing between a neutral stimulus (e.g., a dog) And an aversive experience (e.g., being bitten by the dog) which provokes a fear reaction
59
What are the limitations of classical conditioning in explaining the aetiology of anxiety? (x3)
Model offers insight into development of a fear or phobia; But doesn't explain maintenance of fear response Or why some develop it and others not
60
How does operant conditioning explain the aetiology of anxiety? (x5)
Avoidant behaviours negatively reinforced, maintaining anxiety - Person never has opportunity to *Face fears, *Learn they can tolerate their anxiety, *Challenge maladaptive beliefs about remaining in situation
61
Give an example of developing a fear of snakes through operant conditioning (x5)
``` See snake Become anxious Run away Anxiety decreases Likelihood of avoidance and fear grow ```
62
How does vicarious/observational learning explain the aetiology of anxiety? (x4)
Conditioning doesn't explain why some develop anxiety in absence of aversive experience Learning through modelling *Learn to avoid stimuli if one observes others showing a strong fear response to such stimuli *Adaptive to copy others' fear
63
What is the role of cognitive processes such as perception, memory, attention in developing/maintaining anxiety disorders? (x5)
Misinterpret ambiguous situations as dangerous - physical and cognitive distress Maladaptive thoughts/beliefs can impact memory, attention, information processing Catastrophic misinterpretation - esp in panic disorder Attentional bias to threat - hyper vigilance Thought suppression - causes more intrusions
64
Describe the 'fear of fear' model/cycle of panic attacks (x4)
Catastrophic misinterpretation of physical sensations Panic attack Increased physical arousal/worry about another attack Vigilance of bodily symptoms
65
How does the ACT hexaflex of psychological rigidity relate to the aetiology of anxiety? (x6)
Fusion of thought and awareness – eg no one likes me - fuses with sense of self through our attention, making it 'real' Which makes you avoidant of those situations Focussed on beliefs about our past, and that future will be same Values go, because we're focussed on avoidance Leads to disorganised behaviour No safe place, which should be our awareness
66
What is the take-home message about the aetiology of anxiety? (x1)
It's a complex relationship between genetics, CSN mechanisms, cognitive, behavioural, social and environmental factors
67
What biological treatments are available for anxiety disorders? (x3)
Tricyclics - side-effects too bad SSRIs - combat serotonin depletion associated with anxiety, less harm than tricyclics Benzos - GABA, effective early in TX, but side-effects and addictive
68
What elements of CBT are used to treat anxiety? (x4)
Psychoeducation Relaxation Cognitive Techniques Exposure Therapy
69
What is taught in psychoeducation about anxiety in CBT? (x3)
Anxiety is common, typically short-lived and normal Anxiety can be adaptive and functional Can never eliminate anxiety altogether
70
What role does relaxation play in CBT for anxiety? (x1) | Teaching clients... (x7)
``` Addresses the physiological component of anxiety Variety of relaxation techniques: *Progressive Muscle Relaxation *Imagery/visualisation *Abdominal breathing Relaxation is a skill, pick the right time Make the time, keep it short and simple Create a relaxing environment ```
71
What is involved in cognitive therapy for anxiety? (x4)
``` ABC model (cognitions as mediators) Identification of anxiety-provoking cognitions (thought monitoring) Cognitive restructuring *Target negative, unrealistic interpretations common to anxiety sufferers ```
72
What role does exposure therapy play in treating anxiety? (x1) Involving... (x2)
Addresses the behavioural component – overcome avoidance, facing your fears Gradual and repeated exposure using Exposure Hierarchy (most typical) * Imaginal or In Vivo (real life experiences) * Gradual or Flooding Exposure with Response Prevention (ERP)
73
What evidence supports ACT for treating anxiety? (x3)
Acceptance rationale drawn from ACT seems to increase willingness of clients to complete exposure tasks As effective as CBT in treating anxiety disorders Effective in treating treatment resistant clients
74
How does ACT treat anxiety? (x4)
Defusion – recognise your thoughts as thoughts Get your awareness away from target, back to present moment Trying to move away from avoidance, And experience life, accepting that you might feel bad sometimes
