4. Caries:no simple causation pathway

5. Complex: multifactorial • “action of genes, environmental factors and risk-conferring behaviours” • “biology, behaviour and genetics do not completely explain caries.” Fejerskov O. “Changing paradigms in concepts on dental caries: consequences for oral health care.” Caries Res 38: 2004

6. Controlling caries is not just: • Killing one microorganism • Improving tooth resistance • Preventing mutation in one gene • Managing one environmental factor Fejerskov O. “Changing paradigms in concepts on dental caries: consequences for oral health care.”Caries Res 38: 2004

7. The main determinants of health

9. Experience of changing your behaviour?

10. Difficulty of changing an existing or adopting a new behaviour? • not important: what I am doing is okay and I like to do it! • not confident: too hard!

11. Listening to parents whose children had dental treatment under general anesthesia

12. “Well, I have an experience…we talk to a dentist, the rate was $100/hr. They gave us a one-hour long lesson about how to take care of our child’s teeth…” Amin M, Harrison R. Pediatr Dent 29: 2007

13. “At the end, the only thing we got out from it was to chew gum. The things we got out from it could also be found in the newspaper and books, so why do we still have to take that one-hour lesson from the dentist?”

14. Advice-giving Describes or recommends a preferred course of action”“you should”“you ought to…”

15. Advice-giving: two elements • Information • Persuasion • Telling people what to do • undermines autonomy • generates resistance

16. Frustrated!!!

17. The Transtheoretical Model: a framework for understanding the process of change“Stages of change”James Prochaska and Carlo DiClemente • importance of tailoring intervention to individual’s stage of change

18. recovery relapse Action Maintenance Preparation Contemplation Precontemplation Stages of Change Prochaska et al, 1991

19. Pre-contemplationIndividual has problem (may not recognize it) and has no intention of changing • traditional health promotion & health education • not designed for such individuals • doesn’t match their needs

20. ContemplationIndividual recognizes the problem; seriously thinking about changing • more aware of pros; even more aware of cons • balance between costs/benefits of change = ambivalence • stuck here for long time

21. Preparation for changeIndividual recognizes problem and intends to change behaviour soon. Some change efforts reported • intending to take action in immediate future, e.g. consult professional • some significant action in the past year

22. Actionconsistent behaviour change • made specific modifications in practices • risk of relapse

23. Maintenance • working to prevent relapse

24. Termination • change habitual and embedded

25. Stages of change: Remember! • people move backwards & forwards • if you talk to people expecting them to be further along; expect resistance!

26. Stages of change: Remember! • parent may not be ready • likely won’t say • “I want to change” • different stages of “readiness” = be flexible!

27. Applying stages of change to an intervention:Motivational Interviewing“M. I.”William MillerStephen Rollnick

28. Work with problem drinkersMiller 1978 • control group (advice, self-help book) • experimental group (10 sessions) • same improvement • better than wait-list!

29. predictor of success = therapist empathy

30. Motivational Interviewing • directive, patient-centred counseling stylefor • eliciting behaviour change • by helping patients to explore and resolve ambivalence Rollnick and Miller, 1995

31. Directive: practitioner provides some structure Patient-centred: patient has opportunity to identify and resolve behaviour change issues Motivational Interviewing

32. “SPIRIT of MI” • collaborate • negotiate • patient is expert • mechanism to change • respect autonomy

33. First principle of MI:Express empathy • see world through client's eyes • share in client’s experience

34. 2nd principle of MI:Develop discrepancy How client’s current way of being will not fulfill their goal

35. 3rd principle of MI:“Roll with resistance” • skillful deflection of client resistance • define problems, then develop solutions

36. 4th principle of MI:Support “self-efficacy” • you can do this! • no right way • others did it, so can you

37. Parental efficacy “Parents’ belief in their ability to take action and administer parental control.” Swick and Broadway. J of Instructional Psychology 24: 1997

38. Familial and cultural perceptions and beliefs of oral hygiene and dietary practices among ethnically and socio-economically diverse groups. Adair P, Pine C et al. Community Dental Health 2004:21 • 2822 parents of 3-4 year olds • Parental efficacy (self-belief) and attitudes were strongest predictors of • establishing toothbrushing behaviour and • controlling sugar snacking

39. Skills and strategies:more than “being nice!” • Open-ended questions • allow expression of concerns, problems • Affirmations • enhance self-efficacy • Reflective listening • active listening • clarifying not just repeating • Summarizing • reach joint decisions

40. In the dental setting?

41. Practical application • Time • for training and practice • for follow-up • Short time with family • Not our training! • more “action-oriented” • Not easy! • reflective listening • open-ended questions

42. Principle #1: empathyShow concern • Get parent talking about child • open-ended questions • “what is it like to be ...’s Mom?” • “tell me more….” • “it must be hard to…..”

43. Principle #2:Explore discrepancy • Explore discrepancy between • what parent wants for child’s dental health • straight teeth • no toothaches

44. Explore discrepancy between • what parent believes will happen • children have bad teeth • baby teeth not important • too hard to do anything about it

45. Pros Cons Make a “list”

46. Principle #3:“Roll with resistance” • baby teeth not important • don’t argue or disagree • “dentists used to think…” • “do bad teeth run in your family?” • “tell me about other children’s teeth?”

47. Principle #4:Support self-efficacy • you are a really good mother! • you are doing a great job of being a mom • being here today is a good sign

48. Summarize • “Tell me again what you want for ………’s teeth” • Transition to a menu • “I have spoken with other mothers and these are some ideas that they had about good teeth…”

49. Summarize • Using the menu • “worked for other mothers; may not work for you” • focus on the behaviour that parent is most likely to change • Ideas of your own?

50. Identify potential problems and solutions
