1. THEORY

2. What is theory?  “… a set of interrelated concepts, definitions, and propositions that presents a systematic view of events or situations by specifying relationships among variables in order to explain and predict the events or the situations.”  (Glanz, Rimer, and Lewis, p. 25)

3. Theory  “Effective health promotion and education depends on practitioners’ marshaling the most appropriate theory and practice strategies for a given situation.”  “The gift of theory is that it provides conceptual underpinnings for well-crafted research and practice.” (Glanz, Rimer, & Lewis, pp. 30-31)

4. Theory  Generality  Testability  Shape and boundaries, but not specific topic or content

5. Theories are used to …  Guide the search for why people behave in certain ways  Help pinpoint information needed before developing and organizing an intervention program  Provide insight as to how to shape strategies to reach people  Help identify what should be monitored, measured, and compared

6. Concepts & Constructs  Concepts:  Major components of theory  Constructs:  Concepts that have been developed and defined for use in a particular theory

7. Variables  Variables  The measurable forms of constructs  Variables are a measure of a specific construct in a specific situation.

8. Models  “… draw upon a number of theories to help understand a specific problem in a particular setting or context.”  (Glanz, Rimer, & Lewis, pp. 27)

9. Putting it together  A personal belief is a CONCEPT that has been shown to relate to various health behaviors.  Using a THEORY that includes the concept of personal beliefs helps explain why young men don’t think they will ever get testicular cancer.

10. More theory  “Habit is habit, and not to be flung out of the window, but coaxed downstairs a step at a time.”  Mark Twain

11. Planning Models  Like a road map  Present all possible routes you might take to develop, implement, and evaluate a program.

12. Planning Models  PRECEDE/PROCEED  MATCH  CDCynergy

13. PRECEDE/PROCEED Model

14. Behavior Change Theories  The specific route(s) you will take to reach your destination – they suggest a road to follow.

15. Theories and Levels of Influence  Behavior is very complex  Influenced and supported in multiple ways

16. The Ecological Model  Emphasizes the links and relationships among multiple factors (or determinants) affecting health

17. Ecological Model Individual Interpersonal Institutional or Organizational Community Public Policy

18. Individual / Intrapersonal factors  Knowledge, attitudes, beliefs (KAB)  Skills  Motivation  Self-concept  Age, gender, genetics

19. Interpersonal factors  Social support / social networks  Social norms, cultural environment  Religious affiliation  Access to social and health services

20. Institutional or organization factors  Educational system  Access to health care  Social Interactions

21. Community factors  Living and working conditions  Public safety  Local public health  Housing  Economic development  Environment

22. Public Policy Factors  Federal, State & Local Policy and Law  Zoning  Taxes  Public Health System  Educational System

23. Behavior change theories with individual focus  The Health Belief Model (HBM)  The Transtheoretical Model (TTM)  Theory of Planned Behavior (TPB)

24. Health Belief Model (HBM)  Developed in the early 1950’s by social psychologists in the U.S. Public Health Service.  Hochbaum & Rosenstock  TB screening

25. Constructs of HBM  Perceived threat  Perceived susceptibility Beliefs about one’s chances of getting a condition  Perceived severity Beliefs about how serious the condition might be

26. Constructs of HBM  Outcome Expectations  Perceived Benefits Beliefs that the advised action will reduce risk or seriousness of the condition.  Perceived risks/barriers Beliefs about the “costs” of taking the advised action

27. Constructs of HBM  Cues to Action  Strategies to activate one’s “readiness”  Self-Efficacy  Confidence in one’s ability to take action

28. Health Belief Model Perceived Susceptibility & Perceived Seriousness Perceived Threat Likelihood of taking recommended action Cues to Action Modifying Factors: age, race, ethnicity, SES, personality Outcome Expectations: Perceived Benefits vs. Perceived Risks/Barriers Self-efficacy

29. Theory of Reasoned Action (TRA)  Constructs:  Attitude toward the behavior Beliefs about the behavior Evaluation of behavioral outcomes  Subjective norms What others think about your behavior How motivated you are to comply with the expectations of others

30. TRA Cont.  Beliefs and Subjective Norms help predict Intentions  Your Intentions predict your actual Behavior

31. TRA Attitude toward behavior Subjective Norm IntentionBehavior

32. Theory of Planned Behavior (TPB)  Developed by Fishbein & Ajzen  An extension of the Theory of Reasoned Action (TRA)

33. TPB versus TRA  Adds the construct:  Perceived Behavioral Control Belief about personal control in combination with belief about the one’s ability to do what needs to be done. Actual Behavioral Control: have the skills and resources needed to quit.

34. TPB Cont.  People will perform a behavior if:  They believe the advantages of success outweigh the disadvantages of failure.  They believe that other people with whom they are motivated to comply, think they should perform the behavior.  They have sufficient control over the factors that influence success or ability to perform the behavior.

35. TPB Attitude toward the behavior Subjective Norm IntentionBehavior Perceived Behavioral Control Actual Behavioral Control

36. Transtheoretical Model (TTM)  AKA: Stages of Change  Developed by Prochaska & DiClemente  Major Constructs:  Precontemplation  Contemplation  Preparation  Action  Maintenance  Decisional Balance  Self-Efficacy

37. Precontemplation  “The care is still in the garage!”  Not thinking about changing behavior in the next six months.  May be unaware of risks or problems.  Needs some work “under the hood.”

38. Contemplation  “The engine is started, but we’re not quite in gear!”  Seriously thinking about making a behavior change, but have not yet made a commitment to action

39. Preparation  “We’re in gear and ready for short trips.”  Ready to take action in the very near future (next 30 days)  Have a plan of action  Experimenting with new behaviors

40. Action  “We’re on the road on a regular basis.”  Actively engaged in new behavior(s) for less than six months.  Efforts are sufficient to reduce risk of disease

41. Maintenance  “We’re on cruise control.”  Sustaining the behavior change for over 6 months.

42. Decisional Balance  The costs and benefits of changing.

43. Self-Efficacy  Confidence that one can be successful in the new behavior across different challenging situations.

44. Relapse  More likely when you are stressed, anxious, or feeling depressed.  More likely if you lack social support or are experiencing interpersonal conflicts  More likely if you return to a setting (environment) that “cues” your old behavior(s)

45. Strategies/process to get from one stage to the next.  Precontemplation to Contemplation  Awareness New information Persuasive communications Experiences

46. Strategies  Contemplation to Preparation  Knowledge acquisition Information Persuasive communications Experiences

47. Strategies  Preparation to Action  Deciding How-to information Skill development Attitude change

48. Strategies  Action to Maintenance  Skills  Reinforcement  Support  Self-Management  Attitude and attribution change

49. Strategies  Maintenance  Continuation Relapse prevention skills Self-Management Social and environmental support

50. Precontemplation Contemplation Preparation Action Maintenance Decisional Balance Self-Efficacy Transtheoretical Model (TTM)

51. Pro’s of TTM  Encourages less “labeling” terms.  (Precontemplation rather than “loser” or “lost cause”)  Must accept people “where they are”  Behavior change is not viewed as linear  It is easy to stage clients  It is not based on an instant gratification mentality  Allows for stage-matched interventions

52. Adapted from: Autobiography in Five Short Chapters by Portia Nelson I I walk down the street. There is a deep hole in the sidewalk. I fall in I am lost … I am helpless It takes forever to find a way out.

53. II I walk down the same street. There is a deep hole in the sidewalk. I pretend I don’t see it. I fall in again. I can’t believe I am in the same place. It still takes a long time to get out.

54. III I walk down the same street. There is a deep hole in the sidewalk. I see it is there. I still fall in … it’s a habit. My eyes are open. I know where I am. I get out immediately.

55. IV I walk down the same street. There is a deep hole in the sidewalk. I walk around it. V I walk down another street.

56. Social Cognitive Theory (SCT)  A behavior change theory with an Interpersonal / Social network focus.

57. Reciprocal Determinism Characteristics of the Person Environment in which the behavior is performed Behavior of the person

58. Constructs of SCT  Behavior Capacity  Expectations  Expectancies  Self-Control / Self- Regulation  Self-Efficacy  Reinforcement  Observational Learning  Emotional Coping Responses

59. Principles of Modeling  Attention  Remembering  Repetition  Motivation  Model Similarity  Age  Gender  Status  Competence

60. Reinforcement  Any action or event that increases the desired behavior  Present something positive Money New clothes  Remove something negative Nagging Teasing

61. Punishment  Any action or event that decreases the likelihood that the desired behavior will occur.  Present something negative Criticize Policies or laws  Remove something positive Praise Privilege

62. Framework: Social Determinants of Health Community Social Networks Interpersonal Individual Organizational/Institutional Political Population Level Ecological Model

63. Diffusion of Innovations Theory  Rogers, 1983  A behavior change theory with a community focus

64. Diffusion of Innovations  The progressive adoption by members of a community or society of an idea or practice over time.

65. Categories of Adopters  Innovators (<3%)  Independent, risk-takers, eager to try new ideas  Not necessarily the most respected members of the community  Seek info on their own, rely on their own judgment in making decisions about adoption  Try out new ideas and provide the first tests of the utility of the innovation

66. Categories of Adopters  Early Adopters (14%)  Respected members of the community  Opinion leaders  Powerful influence on other potential adopters  Trendy … like to be up on what is good and new  Seen as opinion leaders

67. Categories of Adopters  Early Majority (34%)  Greatly influenced by mass media and opinion leaders  By virtue of their numbers, they begin to form a new norm  Lots of contact with peers, but don’t hold leadership positions.

68. Categories of Adopters  Late Majority (34%)  Skeptical of change  Tend to wait until an innovation is established as a norm before adopting  Motivation is greatly influenced by peers  Don’t like risk and uncertainty

69. Categories of Adopters  Laggards (16%)  Very traditional and conservative  Tend to have less education and lower SES  Socially and geographically mobile  Narrow and restricted communication networks  Suspicious of innovations and adverse to risk

70. Adoption Curve

71. Determinants of Diffusion’s Speed and Extent  Is the innovation better than what it will replace?  Does the innovation fit with the intended audience?  Is the innovation easy to use?  Can the innovation be tried out before adopting?  Are the results of the innovation observable and easily measured?

72. A few more pieces  Predisposing, Reinforcing, and Enabling Factors  Barriers to change  PRECEDE/PROCEED behavioral diagnosis phase

73. Predisposing Factors  Provide the rationale or motivation for a person or group to act  KAB (knowledge, attitudes, beliefs)  Personal preferences  Existing skills  Self-efficacy beliefs  Individual level theories  Intrapersonal are most appropriate for addressing these factors.

74. Reinforcing Factors  Factors that provide reinforcement and reward for actions and encourage repetition of the action  Social support  Peer influence  Significant others (family, spouse, partner)  Employers, teachers, health providers, community leaders, decision-makers

75. Reinforcing Factors Continued  Interpersonal level theories are most appropriate in addressing these factors  Interpersonal level theories suggest communication channels (e.g. significant others or social networks) and methods (e.g. incentives or social supports).

76. Enabling Factors  Factors that provide the means or make the action possible.  Availability of programs or services or skills training  Accessibility of programs or services or skills training

77. Activity  Pick a theory (Health Belief Model, Theory of Planned Behavior, Transtheoretical Model, Social Cognitive Theory OR Diffusion of Innovation Theory)  Map out the constructs of the theory Where do these constructs fit into the Ecological Model?  Give a brief (at least one sentence) explanation of each construct  Provide examples for each construct that relates to your topic  List as many predisposing, reinforcing, and enabling factors as you can think of for the topic.  Keep this model for Wednesday’s class.
