2. In order to comprehend these approaches
E N D
1. 1 Using Theories in Social Work Cognitive-Behavioural Approaches
2. 2 In order to comprehend these approaches – what do we need to know?:
Some necessary background– psychological concepts – about how learning – particularly social learning takes place. First background to behavioural, and then second CBT approaches
Problems with simple behaviourist approaches
Explanation of what CBT is
Some distinctions between different types of understandings of CBT
Some indication of where and with whom these approaches work well – not always traditional social work settings
Strengths and weaknesses of CBT
Some concluding, summative thoughts
Also will help if we use some interesting case studies – I will do this at appropriate junctures
3. 3 a) Background to Behaviourism: Some Psychological Concepts about Social Learning Three main theories of social learning:
Respondent or classical conditioning
Operant, or instrumental, conditioning
Social Learning Theory and modelling – more important for CBT – as it involves focus on cognition
4. 4 1 Respondent Conditioning Presentation

7. 7 2 Operant, or Instrumental, Conditioning Anne cannot control her 7 year old, daughter Jasmine’s behaviour without resorting to physical slaps
She has been referred to you
Anne describes how Jasmine when shopping will scream and shout until she gets what she wants.
She takes Jasmine out of the shops…buys her sweets…doesn’t work…..hits her legs…doesn’t work
Now resorted to buying sweets as a bribe before going out
Why do you think Jasmine’s behaviour is continuing?
8. 8 For Jasmine clearly: Sweets are very desirable….and so the strong desire for them overrides any punishment so far offered
Rewards strong; punishment weak
Jasmine KNOWS she will always get what she wants in the end…….
………let’s diagrammatise an operant understanding of what is happening here
9. 9 Operant conditioning – we don’t just learn through association with stimuli…rather we learn behaviours as a result of the stimuli that immediately follows their expression In other words we learn as a result of the consequences of actions rather than the stimulus that precedes them
Operant conditioning
Expression
of behaviour Stimulus
(response) (consequence)
Crying Demanding
Environmental Cue
(antecedent stimulus)
Shopping
Other example of James and father
10. 10 The different uses and aims of behaviour therapy – note focus on behaviour alone Tackling generalised conditioned responses – going out/get dirty; school phobias; etc
Aim would be extinction of generalised response – taking child to school/park in stages – I used it with various phobias – spider phobia
Some kinds of behaviour are incompatible with others – counter conditioning – associating desirable responses with particular stimuli
Systematic desensitisation common technique – relaxation/personal support – e.g. transvestites/ agoraphobia/sexual therapy – reducing anxiety and therefore premature ejaculation; enuretic children
11. 11 Ethics/politics of behavioural therapy In the 1960s there was a fearful debate about Skinner’s work – the behaviourist – notably in response to his book ‘Beyond Freedom & Dignity’
Principally critics were concerned about:
The absence of concern for ‘the mind’ – the ghost in the machine
The potential power that conditioning gave to the therapist to shape behaviour, and most importantly
The potential power afforded to corporate and political power holders to condition their workforces/populations – cf Orwell’s 1984 and Huxley’s Brave New World
Have any of you seen Stanley Kubrick’s Clockwork Orange or read the novel of the same name by Anthony Burgess?
12. 12 Technical efficiency cannot override moral responsibility Certainly pure behavioural techniques can appear ‘non-human’ or inhumane
There is a real problem as we are aware that some of our fears have been realised in some residential token economy, behavioural modification settings such the Pindown scandal
They can smack of the imposition of values – cf manipulation
Behavioural therapists argue that consent is always vital – and all therapy involves similar issues of limiting user choice – but what when consent is related to gaining privileges?
13. 13 Background to CBT : Social Learning Theory and Modelling Background to these approaches can be found in the work principally, but not exclusively, in work of Bandura (1977)
People’s learning is achieved through their perceptions and thinking about what they experience. They learn by copying the examples of others around them
2 sets of expectations:
Outcome expectations – behaving in a certain way will produce a particular outcome
Efficacy expectations – belief that the person has the capacity to produce successfully the behaviour necessary for achieving the desired outcome
14. 14 Problems with basic learning theory - Bandura
Difficult to always define what a person’s performance expectations are without close observation
May have distorted view of our own efficacy – “I’m just no good at writing essays”
Nevertheless, we can see where the change emphasis needs to be on reinforcement of positive thoughts to achieve desired outcomes
15. 15 What is Cognitive Behavioural Therapy?
Let’s start with a basic observation of an emotive episode that may happen to any of us
Three elements:
A What starts it off? ANTECEDENT/ACTIVATING EVENT
B Beliefs about B BELIEFS
C Reaction CONSEQUENCE
Example
A Friend passes us in street & ignores us
B “I’m not worth acknowledging”; “nobody gives a s…”; “seen as worthless as a friend…therefore as a person”
C Feelings - lonely and depressed Behaviour – withdraw into self
So at root CBT is about:
How you think about yourself, the world and other people
How what you do affects your thoughts and feelings
Self Action
Unhelpful – Go home and avoid this friend and others
Helpful – get in touch and see if they are ok
16. 16 Related and building on learning theory – Cognitive Theory and Behavioural Work - CBT There are a range of related theories here – see Payne pp 121-123 – see also slide 19
Cognitive theory is basically suggesting that as behaviour is affected by perception or interpretation of the environment during learning
Inappropriate behaviour must be a misperception
The interesting issue here is that behavioural therapies or CBT are discussing altering disorders in thinking – in the MIND – when as we saw above initially behaviourism only focussed on behaviour
17. 17 ABCs – Antecedent; Beliefs; Consequence We can see that the basic tool deriving from these approaches for practical work by psychologists & social workers is this use of A, B, Cs
In terms of a basic tool kit that has a hands on utility – then these behaviour therapy approaches are now widespread in contemporary NHS and social care work
Widespread use in work on:
Stress/anxiety; depression; addictions; panic; agoraphobia & other phobias, social phobia, bulimia, obsessive compulsive disorder; post traumatic stress disorder and, now, in some cases schizophrenia
Huge recent investment by NHS – see below
18. 18 Classification…4 types of cognitive-behaviour therapies – according to Scott & Dryden (1996)
Coping Skills – 2 elements self verbalisation (instruction to ourselves) & changes to environment e.g. stress reduction -
Problem solving – cf Perlman’s psycho-analytic work – see life as a process of resolving life issues lock onto a problem generate a no of solutions – get client to choose best for them
Cognitive restructuring – particularly used when people are unreasonably negative – ‘awfulising’ – as Ellis calls it in his rational-emotive beh.therapy technique…..irrational beliefs at the root of people’s problems e.g. lorry driver – see below
Structural cognitive therapy – concerned with 3 ‘structures’ of belief - core beliefs; intermediate beliefs or explicit descriptions of the world; and peripheral beliefs. The later are used as become the immediate target of action but the aim is to alter the other two
19. 19 Ellis’s ABCDE theory of emotions – cognitive re-structuring
A Activating event of situation – wife dies unexpectedly
B Beliefs – self defeating belief – “my fault should have called GP earlier”!
C Consequences – emotional/behavioural - “I deserve to suffer/be depressed/don’t need/deserve help
D Disputation – challenge irrational belief and replace with rational – “you did right and do not have power over life and death.”
E Evaluation – goes alongside D – so that the client reappraises the A, B, C process
20. 20 Effectiveness of CBT Strengths
Evidence based practice - & examples of success in certain contexts i.e.with addictions & stress
Relatively easy to use – but need to know techniques well & have good listening & presentational skills
Widely applicable
Time limited
21. 21 Possible Problems with Use of CBT: Can be a long process – 5 to 20 one hour sessions
Favourable outcomes when compared to no intervention or on subjects who select this therapy through public advertisements – much less so on random clinical selection
Example - used a great deal for depression but in Nat Inst of Mental Health Study of depression – CBT fared less well than interpersonal therapy or GP management with anti-depressants
Can be difficult for some patients to verbalise their feelings
Does not really address the causes of problems
Danger when CBT is used for clients that have more complex underlying psychiatric disturbances e.g. anger management progs in prisons
Increasingly seen as a panacea in treating certain conditions cheaply
22. 22 Conclusion Very wide influence in & around social work – particularly, but not exclusively, in mental health settings
Usually used by social workers in a stripped down form around ABCs
Fits in with task centred, focussed approaches planned, clear agreed goals
Many elements of the practice can show empirical validated success
Continues to generate some concerns due to its overly technical rational scientific nature, certain ethical issues & occasional inappropriate application
