What is motivational interviewing?
Motivational interviewing is a health psych interviewing technique that promotes the patient’s personal autonomy and intrinsic motivation.
Giving people advice to change is often unrewarding and ineffective; invokes a lot of resistance and is unsustainable without intrinsic motivation.
–> decisions are left up to the patient, MI helps them think through what would work for them and what is holding them back. offer expertise to add insight, not tell them what to do.
Discover their own interest in considering and/or making a change in
their life (e.g., diet, exercise, managing symptoms of physical or
mental illness, reducing and eliminating the use of alcohol, tobacco,
and other drugs)
Express in their own words their desire for change (i.e., “change-talk”)
Examine their ambivalence about the change
Plan for and begin the process of change
Elicit and strengthen change-talk
Enhance their confidence in taking action and noticing that even
small, incremental changes are important
Strengthen their commitment to change
Health Action Process Approach
3 predictors of behavior change:
- Risk perception: knowledge of the risks associated with certain behaviors
-Outcome expectancies: “If I stop smoking, I will save money”. Ensure people know the strategies to produce their desired effects. - Perceived self efficacy (this is what facilitates the movement to action): - Individual’s beliefs in their capabilities to exercise control over challenging demands and over their own functioning
- Optimistic self-beliefs (I can make this change even if…)
- Self-doubt (There is no point, I can’t change, I will not succeed).
-health psychologists try to get people to optimistic self beliefs
Stages of change:
- Intention to change
– requires the 3 predictors - Planning
-Implementation interventions: make plans that specify when, where, and how of a desired action. STRUCTURE! This is important because it makes cognitive links between situational circumstances and the goal behavior.
—when planning is done well, prpocrastination is reduced. - Initiative
- actual goal pursuit - Maintenance
Requires self regulatory skills and strategies (attainable goals, incentives, social support). - Recovery
- When people pursue their goal by planning details, trying to act, invest effort and persistence, possibly failing, and recovering or disengaging.- Optimistic sense of control is key
If they feel that they out of control or like their goal is unachievable, they will become disengaged.
How can we invoke behavior change in people?
Behavior change can be approached by two avenues.
Community based
- PSA’s
- Incentives or consequences (policies, taxes)
- Workplace programs (step challenges)
Individual
- Health psychologists or physicians
- Person driven change
Precede/Proceed Model
- Identify health problems
- Identify lifestyle and environment elements that contribute to the targeted behavior
- Analyze background factors that predispose, enable, and reinforce these lifestyle and environmental elements
- Implement a health education program
What are effective health education campaigns?
Campaigns that merely inform people
of the hazards of certain behaviors
(e.g., antismoking messages) are typically ineffective
- fear based, loss frame
Multifaceted campaigns that present information on several fronts are
generally more effective than “single-shot” campaign
combination of activities, gain frame, provide environmental changes
Successful information campaigns…
- use peer role models
- Model saying no and showing other behaviors (normalize saying no)
- Campaigns are less effective among ethnic minorities
Other government tactics are increasing aversive consequences
- increasing cigarette tax, increase punishment associated with underage smoking
- Banning smoking in public area
Health education
any planned intervention involving communication
that promotes the learning of healthier behavior
Why don’t scare tactics work?
People feel invincible→ it won’t happen to me.
Novelty wears off → they get used to the aversive imagery or warnings
Transtheoretical model
- precontemplation
- contemplation
- preparation
- action
- maintenance
- relapse
Premack Principle
More rewarding, higher-frequency behaviors could reinforce the less rewarding, low-frecuency behaviors.
Keys to individual change
- Social support
Small achievable goals
Habit Reversal
Find the motivation
Have to want to do it to overcome lack of willpower
Don’t just add new behaviors to a full plate
E.g., Can’t exercise if you don’t have time to ex
Classical conditioning
Association of contiguous events
Operant conditioning
Role of reinforcement- antecedent, behavior, and consequence
Benefits of exercise
- Improves mood
- Improved CD health
- Promotes neurogenesis
- Functional plasticity
- Increases insulin sensitivity, lowers blood sugar
- Increases sleep
- Decreases cancer risk
- Decreases anxiety and depression
- Improves leukocyte telomere length
Recommended exercise time
Moderate intensity: 150 min/week
Vigorous intensity: 75 min/week
47.9% actually meet the recommended exercise time.
Exercise and weight control
Lower ghrelin during
aerobic and resistance
exercise
*Elevated peptide
tyrosine-tyrosine (PYY)
after aerobic exercise
*Reported reduced
feelings of hunger after
aerobic and resistance
exercise
Exercise and protection against chronic illness
*Increase physical
strength, maintain bone
density with regular
exercise
*Reduction of risk for
chronic adult illnesses:
cardiovascular disease,
certain cancers, diabetes
and metabolic syndrome
*Lowered triglycerides,
lower LDL “bad”
cholesterol levels and
higher HDL ”good”
cholesterol levels
*Delay of some agerelated declines in white
blood cells
Psychological Well-Being
*Improved mood and
well-being
*Increased buffer against
stress, anxiety and
depression
*Predicts better cognitive
functioning and reduced
risk of dementia and
Alzheimer’s disease
Factors positively associated with adult physical activity
- postsecondary education
- higher income
- enjoyment of exercise
- Expectation of benefits
- Self efficacy (belief in ability to exercise)
- Access to facilities
- Social support
- enjoyable scenery (green space)
- safe neighborhoods
Who sticks with exercise?
- People that enjoy
- Formed a habit
- Social support
- Favorable attitude and strong self efficacy
Hunger biological process
Ghrelin: secreted by the stomach wall and triggers feelings of hunger as mealtime approaches. In dieters who lose weight, ghrelin increases.
Leptin, produced by adipose tissue, suppresses appetite as its levels increases. When body fat decreases, leptin levels fall, and appetite increases.
Insulin: A rise in blood sugar levels after a meal stimulates the pancreas to secrete insulin, which suppresses appetite by acting on the brain.
PYY: The hormone PYY, secreted by the small intestine after meals, acts as an appetite suppressant that counters the appetite stimulant ghrelin.
Roles of belief in metabolism
people who had the “indulgent milkshake” felt that they had eaten more and reacted as though they ate something more fattening. Lower levels of ghrelin after eating. Ghrelin levels barely changed in sensi-shake group.
(both grousp had the same shake).
- Approach eating healthy foods with an indulgent mindset??
- Restriction vs indulgence
Obesity in the US
Prevalence of obesity has increased 30.5% to 42.4% from in the past 20 years.
Overall obesity rate in the US is 20%.
This tends to be more of an issue in the South.
Obesity health implications
increases the risks of hypertension, stroke,
myocardial infarction, certain cancers, and,
especially, type 2 diabetes
- liver diease
- dementia
Biopsychosocial model of obesity
Genes: 50% of heritability
Social/cultural eating habits and access
–food deserts and food swamps
–sedentary lifestyles
