1. CBT for chronic pain: state of the art Stephen Morley
Plenary to the British Pain Society
2nd April 2009
2. Outline What is CBT?
How has it been applied to chronic pain?
What’s the evidence?
What needs to happen next?
3. A current usage of the term “The term CBT varies widely and may include self instructions … relaxation or biofeedback, developing coping strategies, changing maladaptive beliefs about pain and goal setting … varying selection of these strategies … embedded in a more comprehensive pain management program that includes functional restoration, pharmacotherapy, and general medical management.”
5. The issue of diagnosis
Does (medical) diagnosis matter
or
can we lump chronic pains together?
6. Cumulative trials over years
8. The effect size
9. CBT vs active treatment
10. Hoffman et al 2007 - back pain
11. Eccleston et al 2009
12. Effectiveness
13. ACT programme at Bath
14. The case of the shrinking effect size Bigger and better trials
less bias, better quality
Poorer treatment implementation
lower doses, less skill, less specific fidelity
More difficult, severe patient problems
Less precise formulation of the problem
vague specification of CBT
15. Trial qualityBigger and better trials less bias, better quality
16. Quality scale for psychological treatment trials
17. Trial quality over time
18. Effect size and quality
19. Methodological quality
20. Size matters
22.
23. Treatment implementationPoorer treatment implementationlower doses, less skill, less specific fidelity
24. Trial quality over time … treatment
25. Is there a model, or, what’s in the tin?
26. Assessing treatment implementation & fidelity
27. Treatment implementationPoorer treatment implementationlower doses, less skill, less specific fidelityFormal evidence is largely absentWe haven’t done the trials with robust methodologyImpressions – therapist training & supervision often not reportedFidelity / competence probably inadequately measured
28. More difficult, severe patient problemsEvidence not fully evaluated
29. Less precise formulation of the problemVague specification of CBT and problem of pain
30. Remember this …. “The term CBT varies widely and may include self instructions … relaxation or biofeedback, developing coping strategies, changing maladaptive beliefs about pain and goal setting … varying selection of these strategies … embedded in a more comprehensive pain management program that includes functional restoration, pharmacotherapy, and general medical management.”
31. General protocol in CBT Principles
Collaborative and consultative engagement
Active practice of skills
Education about chronic pain and its treatment Goals
Improve physical fitness
Reduce disability
(Re) introduction to work
Increase effective /adaptive problem solving
Reduce pain related fear
Reduce pain related depression
32. Principles … Do you use behavioural principles?
Analysis of antecedents, behaviours and consequences
Setting conditions
Discriminative stimuli
Identify reinforcers
Contingency management Do you use cognitive therapy principles?
Identify core non-functional beliefs
e.g. ‘if I move I will harm myself’
Design individualised behavioural experiments to test belief – behaviour links
33. Fear-Avoidance influences on behaviour
35. What’s next?
Improve trial quality
some ‘simple’ changes
Size, implementation
Refine what’s in the tin
develop more focussed and testable models
36. The evidence cycle – not a one-way street Efficacy studies
Randomised
Controlled
Trials
Evidence-based practice
as policy
Practitioners Practice-based
evidence
Effectiveness studies
Routine
Clinical
Treatment
Practitioners
37. Two more issues
Can we develop dichotomous outcomes
- and how much change is required?
Can we use trials to benchmarking clinical programmes?
38. Turning continuous measures into dichotomous ones
39. Turning continuous outcomes into dichotomous ones
40. Outcome categories - efficacy
41. How much change do you want?
42. Effectiveness + benchmark
