Yale-Griffin Prevention Research Center www.yalegriffinprc.org

1

Modules for Lifestyle Counseling

• Module 1 provided an overview of the obesity epidemic and explained the importance of lifestyle counseling.

• Module 2 demonstrated how to write an exercise prescription and give basic nutritional advice.

• Module 3 provides an overview of behavior modification constructs that inform lifestyle counseling efforts.

Behavior Modification

• Integrating behavioral modification models into the primary care setting has the potential to facilitate patients’ behavior change.

• Improved health behavior may be achieved by: – Individualizing intervention to patient characteristics & needs– Setting goals & problem solving with patients– Multiple follow-up contacts– Support of patient’s social and physical environment; integration

with community opportunities

The Five As

4

The 5 As

Lifestyle change can be facilitated by:

• Listening to patients• Considering patient priorities • Developing collaboration with patient• Incorporating patient values, preferences and social

environment• The 5 As mnemonic helps to promote patient lifestyle

change: Assess, Advise, Agree, Assist and Arrange

5

The 5 As: Assess

• Assess patient’s current health status.

• Assess patient’s physical abilities and current level of physical activity.

• Assess patient’s current dietary habits.

• Assess patient’s readiness for change

Assessments can be done using a brief questionnaire; office staff can assist.

6

The 5 As: Advise

• Advise patient regarding health risks; relate risks to patient’s recent lab results and/or current symptoms.

• Advise patient on the potential benefits of behavior change.

• Provide guidance for dietary change

• Provide exercise prescription using FITT

(Frequency, Intensity, Type & Time)

7

The 5 As: Agree

• Agree with the patient if he/she is planning a lifestyle improvement.

• Collaboratively develop a personalized action plan.

• Set specific goals for physical activity and nutrition based on patient interest and confidence in the behavior (time, duration, frequency).

8

The 5 As: Assist

• Assist patient to identify personal barriers to adopting lifestyle changes.

• Assist in developing strategies to overcome barriers.

• Assist to locate community opportunities for weight loss and physical activity and social support.

Provide written copy of plan to patient and maintain in office medical record.

9

The 5 As: Arrange

• Arrange a plan for follow-up support and problem solving.

• Telephone calls and mailed reminders

• Ex: “Our office nurse would like to contact you next week to see how things are going.”

13

Locus of ControlA behavior is dependent on the individual’s beliefs regarding the value of the outcome (reinforcement) and the perceived probability of that reinforcement occurring (expectancy).

•Reinforcement can be: – Internal Locus

• Belief in level control and/or responsibility for own health status; events result from one’s own behavior & actions.

– External Locus• Belief that events are determined by the actions of others, fate or

chance (self-efficacy is likely to be low).

Identification of the locus of control (internal/external) will help the clinician choose the most effective lifestyle counseling approach.Gilbert, G.G., Sawyer, R.G., 2000, Health Education, Creating Strategies for School and CommunityHealth.Sudbury, Massachusetts. Jones and Bartlett. 14

Health Belief Model (HBM)

• Focused on attitudes & beliefs of the individual

• An individual will take health-related action if he/she:

– Believes a negative health condition can be avoided

– Expects the health condition can be avoided by taking a recommended action

– Believes in ability to succeed with the recommended health action

Glanz, K., Rimer, B.K., Lewis, F.M., 2002. Health Behavior and Health Education: Theory, Research and Practice. 3rd Ed, San Francisco, Jossey Bass. 15

HBM: Key Concepts

CONCEPT DEFINITION APPLICATION

Perceived Susceptibility

One’s belief regarding the chance of getting a

condition

-Personalize risk based on a characteristic or behavior

-Make perceived susceptibility more consistent with actual risk

Perceived Severity

One’s belief of how serious a condition and its

sequelae are

Specify consequences of the risk and the condition

Perceived Benefits

One’s belief in the efficacy of the advised action to reduce risk of seriousness of impact

Define action to take: how, when; clarify the positive effects to be

expected

16

HBM: Key Concepts, cont’d

Perceived Barriers

One’s belief about the tangible and psychological costs of the advised action

Identify and reduce perceived barriers through reassurance, correction of

misinformation, incentives, assistance

Cues to ActionStrategies to activate one’s

“readiness”Provide how-to information, promote awareness, employ reminder systems

Self-EfficacyOne’s confidence in one’s

ability to take action

-Provide training

-Use goal setting

-Give verbal reinforcement

Glanz, K., Rimer, B.K., Lewis, F.M., 2002. Health Behavior and Health Education: Theory, Research and Practice. 3rd Ed, San Francisco, Jossey Bass Publishers.

17

Social Cognitive Theory

• Based on interactions between behavior, environment, and person forming the basis for action.

• Self-efficacy beliefs influence goals, outcome expectations and perceived environmental impediments.

• Interventions focus on individual’s control of behavior and their environment.

• Goals must be realistic and attainable.

18

Transtheoretical Model (TTM)

• Model was developed for smoking cessation. • Health behavior changes occur in 5 stages (Stages of

Change) reflecting patient motivation.• Individualized intervention is based on readiness to

make lifestyle change. Affected by:– Decisional Balance: reflects the pros and cons of the

behavior– Self-Efficacy: situational confidence with ability to perform

task.

TTM: Stages of Change

CONCEPT DEFINITION APPLICATION

PRECONTEMPLATIONUnaware of the problem and has

not thought about change; perceives cons outweigh pros

Increase awareness of need for change, personalize information on risks and

benefits

CONTEMPLATIONRecognizes problem; considering

change in the near futureMotivate, encourage to make specific plans; highlight advantages of change

PREPARATIONMakes a plan; chooses a start date;

setting goalsAssist in developing concrete action, day-to-day plan; discuss challenges

ACTION Implementing specific action planGive feedback, problem solve, social support, reinforcement; lapses may

occur

MAINTENANCEContinuing desirable actions or

repeating periodic recommended steps

Assist in coping, reminders, finding alternatives, avoiding relapses. Continue to praise and support

Practice. San Francisco, CA: Jossey-Bass Publishers.20

TTM: Self-Efficacy

• Situation-specific confidence; coping with frustration.• Important predictor of weight outcomes.• Enables the individual to perform a behavior change

successfully and deal with times of temptation.• Assists with pursuit of goals despite difficulties & lapses.• Self-efficacy may improve as goals are met as well as

with verbal support from others.

21

TTM: Processes of Change

Ten actions individuals utilize to proceed through the stages of change; serve as guides for designing interventions.

1. Consciousness raising 6. Helping relationships

2. Dramatic relief 7. Counterconditioning

3. Self-reevaluation 8. Reinforcement management

4. Environmental reevaluation 9. Stimulus control

5. Self-liberation 10. Social liberation

22

TTM: Processes of Change

1. Consciousness raising: Increasing awareness and acquiring new knowledge that support behavior change.

2. Dramatic relief: Feeling the unpleasant emotions that accompany ‘unhealthful behavioral risks’.

3. Environmental reevaluation: Seeing the negative or positive affects of one’s healthful or unhealthful behaviors on their social and physical environment.

4. Self-reevaluation: Understanding behavior change is a component of one’s identity.

5. Self-liberation: Diligence in one’s commitment to change behavior.

23

TTM: Processes of Change

6. Helping relationships: Finding and utilizing a social environment supporting behavior change.

7. Counter-conditioning: Replace unhealthy behaviors with healthier alternatives.

8. Reinforcement management: Provide more rewards for healthy behavior change and reduce rewards for unhealthy behavior change.

9. Stimulus control: Eliminate cues to negative behaviors and add new cues to encourage positive behaviors.

10. Social Liberation: Recognizing that opportunities supporting positive behavior change are improving.

24

Pressure System ModelPSM

25

Pressure System Model (PSM)

•Applies stages of change to counseling interventions in primary care environments:• 2-question algorithm identifies patient's counseling focus• Separates the two elemental goals of behavioral counseling:

1. Raising motivation2. Overcoming resistance

• PSM derives its name from meteorology – differences in barometric pressure determine wind direction.

– Movement will go from high to low pressure. As motivation increases, resistance will be overcome- or vice versa.

Katz DL. Behavior Modification in Primary Care: the Pressure System Model. Prev Med. 2001;32:66-7226

Pressure System Model (PSM)

• Behavior change requires the right “MO”:– M = Maximizing Motivation– O = Overcoming Obstacles

• Raising motivation is a standard approach for behavioral counseling in a primary care setting using motivational interviewing

Motivation must exceed resistance for behavior change.

Change will not occur if perception of difficulty is greater than the rewards.

Katz DL. Behavior Modification in Primary Care: the Pressure System Model. Prev Med. 2001;32:66-72

27

Motivational Interviewing• Style of patient-practitioner communication,

specifically designed to resolve ambivalence and build intrinsic motivation for patients’ behavior change.

• Focuses on creating a comfortable atmosphere without pressure, coercion or confrontation.

• Patients are better able to:– Share their concerns about changing– Understand their reasons for or against making changes– Make informed decisions– Feel invested in their choices

• Encourages self-efficacy.

Motivational Interviewing

STANDARD Approach to Behavioral

Counseling

MOTIVATIONAL INTERVIEWING Approach to Behavioral Counseling

Focused on fixing the problem Focused on patient's concerns, goals, values

Authoritarian relationship Egalitarian partnership; client self-direction

Assumes patient is motivated Match intervention to patient level

Advise, warn, persuade Emphasize personal choice; elicits from client

Ambivalence = the patient is in denial Ambivalence = normal part of the change process

Goals are prescribed Goals are collaboratively set

Resistance is met with provider argumentation and correction

Resistance is an interpersonal pattern influenced by provider behavior; provider should shift responses

Miller W, Rollnick S. Motivational Interviewing. The Guilford Press; Second Edition edition (April 12, 2002) 29

Motivational Interviewing

OARS Approach:

- Open-ended questions

- Affirmations

- Reflective listening

- Summaries

Empathy by clinicians using the OARS approach in motivational interviewing promotes an attitude of acceptance, supports collaboration, and builds a solid foundation of practitioner-patient communication.

30

OARS Approach

• Open-ended questions:– Help elicit less “biased” information in comparison to close-ended

questions which put the patient in a passive role.– Usually begin with “Tell me about…”

• “Tell me about how your activity plan is going?”

• Affirmations:– Statements of appreciation and understanding are important for

building and maintaining rapport.– Offer positive affirmations to patients by acknowledging their efforts

to make changes (small and large).• “You took a big step by coming here today.”• “That is great that you were able to be active every day this week.”

31

OARS Approach

• Reflective listening:– Involves trying to better understand what the patient means by

reflecting it back in a short statement.– Helps keep the patient thinking and talking about change.

• Patient: “It is difficult for me to move around.”• Physician: “Sounds like you are finding it difficult to be physically active.”

• Summaries:– Used to transition to another topic (usually mid-consultation).– Involves highlighting both sides of a patients ambivalence.

• “You have several reasons for wanting to be physically active. You say you would like to get more exercise. On the other hand, you say that finding time is a hassle. Is that how you are feeling?”

32

PSM: Five Counseling Scenarios

COUNSELING SCENARIO APPLICATION

Patient is precontemplative and has not attempted behavior

change

Intervention should focus on raising motivation and should focus on what should be changed and how it can be

done

Patient is contemplative or preparative and has not

attempted behavior change

Motivation should be elevated, strategies should be identified to

overcome potential barriers, and focus should be on why changes should

be made and how it can be done

Patient is modifying behavior or is maintaining behavior change

Maintaining motivation should be encouraged, strategies should be

developed for new obstacles, focus should be on how and why to sustain

changes33

PSM: Five Counseling Scenarios

COUNSELING SCENARIO APPLICATION

Patient has a lapse to original behaviors

Intervention should discuss cause(s) of lapse, assuage feelings of remorse,

encourage motivation, and reinstate and maintain internal locus of control

Patient is precontemplative or contemplative and has attempted

to modify behavior

Motivation and self-esteem should be raised, locus of control should once again

be internalized, discuss external influences, and strategies should be

developed to overcome barriers

Summary of Module 3• There is strong evidence associating the risks of

sedentary lifestyle and weight gain to increased morbidity and mortality.

• Lifestyle counseling for weight maintenance or loss may have significant benefits.

• Behavioral change models with Motivational Interviewing (MI) techniques may help facilitate patients’ behavioral changes.

• Module 4 provides a specific strategy for incorporating lifestyle counseling in a primary care setting.
