Q

what are some of the questions to think about when clinically assessing anxiety?

Q

describe Clark’s cognitive theory of panic disorder?

that individuals who experience recurrent panic attacks do so because they have an enduring tendency to misinterpret benign bodily sensations as indications of an immediately impending physical or mental catastrophe. e.g. they interpret a pain in the chest as something wrong with the heart

17
Q

what is an example of classical conditioning?

A

Pavlov’s dogs

food poisoning

18
Q

what are examples of operant conditioning?

A

positive reinforcement
negative reinforcement
punishment
extinction

19
Q

what is positive reinforcement?

A

presenting a pleasant stimulus after a desired behaviour has occurred to increase the likelihood of that behaviour again

20
Q

what is negative reinforcement?

A

removing an unpleasant stimulus after a desired behaviour has occurred to increase the likelihood of that behaviour again

21
Q

what is punishment

A

presenting an unpleasant stimulus after an undesired behaviour occurs to decrease the likelihood of the undesired behaviour

22
Q

what is extinction?

A

removing a previously pleasant stimulus to decrease the likelihood of the undesired behaviour

23
Q

what are the 2 types of reinforcement?

A

continuous and partial

24
Q

what is continuous reinforcement?

A

every response is reinforced

25
Q

what is partial reinforcement?

A

reinforcement occurs but not after every response .

e.g. it may depend on the number of responses or a time interval

26
Q

what type of reinforcement do people work the hardest for?

A

partial unpredictable reinforcement e.g. gambling

27
Q

what happens in CBT?

A

you work with a therapist to identify and challenge any negative thinking patterns and behaviour which may be causing you difficulties. In turn this can change the way you feel about situations, and enable you to change your behaviour in future.

28
Q

what is a phobia?

A

A marked and persistent fear triggered by a specific object/situation. It leads to avoidance of that situation

29
Q

what is agoraphobia?

A

fear of crowds and public places

30
Q

what maintains a phobia?

A

negative reinforcement

  1. phobic stimulus
  2. anxiety
  3. avoidance
  4. anxiety reduced
31
Q

what is the treatment of phobias?

A

CBT, mindfulness, graded exposure

32
Q

what is graded exposure?

A

deliberate confrontation of a feared object or situation until the anxiety reduces

33
Q

what are problems with punishment?

A

Physical or emotional harm or injury
Paradoxical attention: can act as positve reinforcer of negative behaviour (any attention better than none)
Teaches aggression as model to solve difficulties
Leads to fear/dislike of person = classical conditioning

34
Q

how do we recognise depression?

A
D = Depressed Mood 
E = Energy Loss
P = Pleasure Lost (Anhedonia)
R = Retardation or Agitation 
E = Eating Changed (Appetite /Weight) 
S = Sleep Changed
S = Suicidal Thoughts (or Future bleak)
 I = I’m A Failure (Loss Of Confidence/Self Esteem) 
0 = Only Me To Blame (Guilt) 
N = No Concentration (Not able to function)
35
Q

how is depression graded?

A

by the number of symptoms…
4= mild depression
5/6= moderate depression
7+= severe depression

36
Q

what must be taken into account when considering a diagnosis of depression?

A

the number of symptoms
have the symptoms been there for over 2 weeks?
how is functioning of daily life?

37
Q

what are the treatment options for depression?

A

CBT or medication

38
Q

describe the cycle of depression and negative thinking?

A

low mood leads to negative thoughts which leads to an even lower mood. it spirals!

39
Q

What is Beck’s cognitive triad?

A

Depression is caused and maintained by negative views of:
The Self
The World/others
The Future

40
Q

what is the cognitive model of depression?

A

the presence of negative life events in addition to one’s perception of or reaction to those events may impact the development and maintenance of depressive symptoms

e.g. early life experiences lead to core beliefs which can cause unhelpful assumptions later on in life which can then cause depression when triggered by an incidence that resonates with the early experience

41
Q

describe the cycle of depression and inactivity?

A

low mood means no pleasure so we do less which means we achieve less and confidence falls so we get no rewards and therefore more time thinking negative thoughts

42
Q

what is Seligman’s theory of learned helplessness?

A

a mental state in which an organism forced to bear aversive stimuli, or stimuli that are painful or otherwise unpleasant, becomes unable or unwilling to avoid subsequent encounters with those stimuli, even if they are “escapable,” presumably because it has learned that it cannot control the situation.
