Behavior Change Health Promotion Programs

January 31, 2008

In an effort to prevent disease and improve peoples’ health and well being,

we continually ask them to…

do things they have not done before stop doing things they have done for years, and do more of some things and less of other

things.

“In order to change behavior…it is first necessary to understand why people behave as they do. The more one knows about the variables underlying a person’s decision to perform or not to perform a given behavior, the more likely it is that one can develop successful behavioral intervention programs.”

M. Fishbein et al., 1992

Health Behavior Principles

Determinants may vary by Type of behavior Life course stage Whether intent is to initiate versus maintain behaviors Whether goal is to eliminate versus

encourage behaviors

Principles of Behavioral Change*

Behavioral change is best accomplished by taking advantage of the multiple opportunities for change in the environ- ment.

Interventionists should consider why people change (mediators) and evaluate the ability of their intervention (interven- tion quality) to effect change in the mediators of interest

*from Maintaining Healthy Lifestyles: A Lifetime of Choices, The International Longevity Center, USA, Ltd.

Principles of Behavioral Change (cont.) The goals of healthy behavior change

should reflect a partnership between the participant and the provider and be stated in concrete terms.

The goals of behavior change should be conceptualized as moving targets that are influenced by personal/ interpersonal, life situations, the environment, & policy.

The “dynamic” relationship between the individual and his

environment…

Can introduce barriers to healthy lifestyle choices and making changes in behaviors or

Can play a significant role in fostering individual behavior change by making active/ healthy lifestyle choices more available.

Principles of Behavior Change (cont.)

The adoption and maintenance of healthy behavior requires basic skills that can be taught.

The maintenance of healthy behaviors requires planned follow-up.

A cost-benefit ratio is important to behavior change (and not always $$). Consider other potentials.

Levels of Behavioral Change Interventions

Interventions can be aimed at multiple levels:• personal or interpersonal

level• the organizational or

institutional level• the health care level• the environmental level• the policy or legislative level

Designing and Evaluating Social and Behavioral Interventions

Intervention Intensity, Effects, and Reach

Individually based interventions are more intensive, have stronger effects, but have less coverage.

Population-based interventions are less intensive per person, may have weaker individual effects, but reach more people.

Designing and Evaluating Social and Behavioral Interventions

Time frame for expected effects Most interventions are based on acute model

but conditions are typically more chronicShort term effects typically stronger than long-

term effects Lagged effects may occur where psychosocial

interventions teach skills or provide services that can be used at critical times

Designing and Evaluating Social and Behavioral Interventions

Identifying optimal intervention in terms of type,dosage and frequency

Different intervention approaches target specific mediators and outcomes--menu

Some intervention efforts are too weak to initiate and sustain desired changes

What is the threshold point after which there is diminishing returns

Personal or Interpersonal Level

Successful interventionsinclude use of self-regulatoryskill training Realistic goal settingIdentification of barriers

and activation of problem solving skills

Self monitoring of target health behavior

Relapse prevention

Recipe for an Effective, Tailored Intervention

Ingredients– Awareness– Knowledge– Motivation– Readiness to change– A strong personal commitment or intention to perform the desired

behavior*– The skills needed to establish and maintain the desired change*– Strong self-efficacy specific to the desired behavior– Opportunities to practice skills and new behaviors in a safe environment– Strong social support– A supportive environment free of any constraints to change**According to a consensus report by the National Institute of Mental Health (Fishbein et al. 1992), these

three factors are viewed as necessary and sufficient for producing behavior change.Human Kinetics ©1999

Personal or Interpersonal Level

Skill training accompanied by support and guidance from trained staff member.

Staff training and support delivered effectively through either face to face or mediated (e.g., telephone, mail, internet) communication

channels. Lay-led group support programs for coping with chronic illness also having success

Piecing Together an Intervention Puzzle

Promote increased

awareness and knowledge

Foster supportive

social networksEnhance

motivation

Establish and maintain a supportive

physical environment

Enhance readiness to

change

Teach or enhance the

skills needed to establish and maintain the

desired behaviorEstablish and

enforce supportive

policies

Intervention puzzle: Four pieces to this puzzle are related to

enhancing individual self-efficacy and strengthening one’s intention to change.

Remaining three puzzle pieces represent the environmental side of the equation.

Imagine there are many ways to arrange the interchangeable pieces to this puzzle.

Tailoring an intervention=customizing the plan of action to meet the target population and needs.

Components of the Stages of Change Model as Applied to Increasing Physical Activity

Stage of ChangePre-ContemplationNot considering increasing physical

activity levels

ContemplationThinks about increasing physical activity

levels

PreparationConsults doctor and visits local

gymnasium

ActionJoins local gym

MaintenanceHas visited gym three times a week for 6

months

Processes of Change

Elicit positive and negative aspects of target behavior(s) and provide simple information (consciousness-raising, dramatic relief)

Motivate and elicit commitment; Enhance self-efficacy; Identify physical activity classes (social liberation)

Identify goals and plan start date and type of physical activity; Use social support (helping relationships); Use stimulus control

Review goals and suggest coping strategies for fatigue, discomfort, lack of motivation etc.; Praise high self-efficacy; Use reinforcement management, counter-conditioning, and stimulus control

Review coping strategies and reassess goals and physical activity type
