Health & Nutrition: Human Health AN EXTENSION SERVICE HEALTH EDUCATION MODEL Contents
The history of Extension
Service has included a vital role in sharing general health information
with clients, especially among rural mothers, children, and agricultural
workers. The major messages of health information have been to promote
good health through nutrition and to prevent injury. With a current focus
on health the Extension system mission has expanded to address health
system problems, health consumerism, as well as statiscally important
individual health concerns.
Health education is
viewed as any combination of learning experiences designed to encourage
people and/or groups to voluntarily practice healthy behaviors. Health
education is an integral strategy to be used in toward realization of
the following goals:
- Citizens will maintain
healthy lifestyles and affordable health care will be available to each
community.
- People will learn
ways to reduce health risks and take an active part in personal health
decisions.
- As informed community
members, people will use commmunity wide planning and decision-making
processes to analyze and take action related to health infrastructure.
A legal mandate to
protect the public health rests with the official public health agencies,
and health providers have professional responsibilities for health care
of their clients. In addition, there are myriad public and private agencies
and private groups operating in the health arena. Each of these health
sectors is involved in the health education and/or health care of consumers,
but the unique role of Extension is to create the learning experiences
that not only provide the information necessary for healthy behaviors,
but also the learning experiences which empower individuals and communities
to use their acquired knowledge in the most effective ways.
While much of the
educational content of Extension health programming is drawn from the
health sciences, Extension aims to carefully target an audience and use
educational methods to create learning experiences. This Health Education
Model is an attempt to link the strengths of Extension community networks
and educational delivery systems with successful methods of health education.
Elements of the model
were found in Extension health programs that have long benefitted clients.
Other elements derive from a review of health education research and the
reported experiences of nurses, physicians, health educators, and public
health professionals. For the information of those who are interested,
a separate review of the literature of behavioral theories, health and
planning models is appended (Appendix A, Parts I
& II). The use of the model does not depend on
an in-depth understanding of the theories involved in changing a health
behavior, but such an understanding can help the educator and program
planner to avoid common sources of difficulty in the delivery of health
education.
The combined elements
of the Health Education Model create a comprehensive process that will
build on existing health education and community organization models,
and allow the Extension professional to be highly effective as a change
agent in the health arena. This comprehensive process of gathering data,
assessing needs and planning a program according to the model is a time
intensive process. The time spent in a community evaluation, however,
can be justified when the process helps to identify effective and efficient
uses of limited resources. It should be emphasized that comprehensive
assessment and planning do not necessarily lead to complicated and expensive
programs...sometimes the process will simplify the end product.
The assumptions integral
to this model are defined here. The assumptions are essentially those
of a behavioral model of healthy acts. It is also assumed that no health
behaviors are not learned or practiced in isolation...that the timing,
content, and people involved are critical to the process.
Specifically, it is
assumed that health promoting actions are a function of awareness,
knowledge, attitudes, skills, culture, opportunities, and/or motivation.
The elements in this behavioral model are both causal and interrelated.
For example, an increase in awareness may lead to health promoting activities
on the part of the individual and/or community. Awareness may also stimulate
curiosity and lead to an increase in knowledge or motivation.
Awareness is
the alerting of the target group or individual to a danger or a positive
factor. Knowledge is more than simple awareness. Knowledge could be described
as awareness with understanding.
Skills are
the specific tools which equip the individual or target group with the
means to solve a problem, take advantage of an opportunity, or otherwise
improve a health situation.
Attitudes may
be positive or negative in regard to their effect on health behaviors.
Attitudes have been viewed as a function of a person's beliefs. If an
individual believes that performing a certain behavior will lead to, on
the whole, positive outcomes, then that person will tend to hold a favorable
attitude toward that behavior. The converse of this idea is that a person
who believes that performing the behavior will have no effect or a negative
effect will view the behavior as having no value for them personally.
Culture is
made up of common sets of symbols, beliefs, rituals, and community norms.
Culture has been included in this model since it can reinforce, limit
or enable the health behaviors necessary for good health. Cultural health
behavior change requires the non-conformist community member to adopt
health behavior changes and to demonstrate a positive effect over time
to many people within his or her sphere of influence.
Lack of Opportunity
to participate in related health activities or services will limit the
effectiveness of any program regardless of the presence of other factors.
The primary limit to opportunity occurs when the health infrastructure
is lacking or inaccessible to the community. Community organization and
development processes may be the most appropriate intervention when community
members identify limited opportunities for health services.
Motivation is included
here as an element specific to the individual. Motivation, an internalized
construct of self-reinforcement, is necessary before an individual can
take responsible actions. A person's health beliefs and attitudes must
be influenced in a positive manner before a person becomes motivated to
change a behavior in the direction of better health. If an individual
is made aware, given relevant knowledge and skills, and has the opportunity
to make necessary changes in attitude and participate in related health
services, it is possible that motivation toward healthy behaviors will
improve. Motivation is also assumed to be a process that involves stages
of change which can be targeted with specific educational methods. However,
it is certain that without motivation, the rest of the elements of health
education will not be effective in changing health behaviors.
The background investigation
is used to determine an overall direction for health education. It includes
an inventory of the health care system and community resources, demographics
of the community, and an examination of the health status of the community
residents. Coupled with the vision behind the effort, this should help
target specific audiences and perhaps identify some broad goals. The overall
strategy should be based upon the existing situation, needs realized on
the part of the planner after careful evaluation of relevant data.
The first step in
conducting a background investigation is to gather and analyze both quantitative
and qualitative data. After analyzing that data, the planner determines
what problems exist and the nature of the target population(s). Some of
this data is readily available as secondary data, but other data must
be primary data and will necessarily be gathered at a local level, usually
by the agent dealing closely with the local community and local organizations.
There is a multitude of data that could be included in the background
investigation, but it must include both local data and data from outside
sources. An index of epidemiological terms, techniques, and resources
for data which may be used in gathering and analyzing data the health
infrastructure is provided in Appendix B.
An essential category
of the data to be gathered includes an inventory of the health infrastructure.
Initially, this inventory might cover the entire state. It will later
be necessary to look more closely at local levels when appropriate target
populations have been established. The inventory should include:
- Doctors per 1,000
population
- Hospitals by category
of care available (primary, secondary, tertiary) within a reasonable
driving distance
- Hospital beds per
1,000 population
- Dentists per 1,000
population
- Mental care facilities
- Clinics
- Low income health
facilities
- Psychological Counseling
facilities
- Wellness Centers
(and Capacity)
- State Public Health
Centers;
- Other agencies
providing information or training (for example, American Heart Association,
American Diabetes Association, American Lung Association, etc.)
Once the health infrastructure
has been inventoried, it is necessary to gather information considering
the health of individuals in the state, county, or community. The data
for this analysis will usually be secondary data which can be gathered
from the Centers for Disease Control, the State Public Health Departments,
and Vital Statistics gathered by national census and health agencies.
Additional data is increasingly being placed on the Internet and is available
on the World Wide Web. When data is gathered with respect to location,
population size, age, gender and other like criteria, there is some basis
for comparison.
Common categories
of health status data include:
- Death by primary
cause (including infant mortality)
- Average age of
death
- Immunization rates
by type of immunization
- Percentage of population
over and under weight
- Percentage of premature
births
- Prevalence and
Incidence of hypertension
- Prevalence and
Incidence of sexually transmitted diseases (and trends)
- Percentage of population
that smokes (within age groups)
- Estimates of prevalence/incidence
of alcoholism and other drug abuse
- Suicide rates
- Percentage of mothers
age 19 and under, and/or unwed
- Estimates of prevalence
and incidence of mental health problems
For examples of background
investigations of health infrastructure and health status indicators (on
natality and mortality factors only) and some demographic assessment using
the Geographic Information System (GIS) see Appendix C, Parts 1 & 2.
This profile should
include the organizations, programs, and the target population that address
the health-related issues and might also be called a directory of services.
Some of the information will be useful later as the target population
identifies needs and programs. In addition, any directory is developed
as a result of the background investigation will be useful to the community.
Categories of populations
should be separated in a community profile and might include age categories.
Examples of age categories include ages in years): Infancy (0-1),Early
Childhood (1-4), School-Age Children (5-18), Young Adults (19-34), Middle
Adults (35-64), Older Adults (65 and over). Special needs programs and
services such as those targeting minorities, the physically disabled,
those living at or below the poverty level, and issue driven programs/services
on chronic diseases, crime, and suicides should also be separate categories
of the profile.
This profile should
become an important resource as the county or community needs are determined
and addressed. Potential issues may be identified in this process, and
possible resources for meeting specific needs of the community will become
more evident to planners.
The demographic characteristics
of the county or community should also help to identify a target population:
- Age Characteristics
(include year of data) Percentage of Population in Various Age Categories
(such as, in years, 0-4, 5-19, 20-34, 35-49, 50-64, and 65 and over)
- Percent Below the
Poverty Level for the total population, for the elderly (age 65 and
over), and for female head of household.
- Life Expectancy
(in years)
- Leading Causes
of Death (Heart Disease, Cancer, Strokes, Motor Vehicle, Other Injuries,
and Poisonings)
Stages of Life characteristics
for the county should include:
- Young Population
Infant (less than 1 year) Death Rate; Early Childhood (1-4 years) Leading
Cause of Death; Later Childhood and Adolescence (5-19 years) Leading
Cause of Death. Include race and sex for each category.
- Early Adulthood
(20-29 years) Leading Cause of Death. If Motor Vehicle Accidents is
the leading cause, include DUI arrests, and other Crimes (violent, property,
and total). Include race and sex for each category.
- Young Adulthood
(30-44 years) Leading Cause of Death which should include information
by race and sex.
Other social characteristics
about the county or community should include:
- Births (Total Number
and Number by Race; Also compare County Rate to State Rate for Total
and by Race)
- Live Births to
Unwed Teenage Mothers (For County and for State include Total Number,
Number by Race, and as a Percentage of the Total)
- Low Birth Weight
Babies (For County and for State, include Total by Race, Percentage
of Total by Race, and as a Percentage of the Total (all races) Live
Births)
- Divorces (Total
Number and Number by Race; Also compare County Rate to State Rate for
Total and by Race)
- Marriages (Total
Number and Number by Race; Also compare County Rate to State Rate for
Total and by Race)
- Educational Level
(Include County and State Data for Categories by Years of Formal Schooling
for Adults as a Percentage of the Total. Categories could include 0-8
years, 9-11 years, H.S. Degree, Some College, College Degree.
- Medical Services
(For Hospitals, include Number of Facilities, Bed Capacity, Admissions/Discharges,
Percent Occupancy, and Average Stay; For Nursing Homes, include Number
of Facilities, Bed Capacity, New Admissions, and Percent Occupancy.)
- Licensed Health
Professionals (Include totals for the following categories: Chiropractors,
Dentists, Osteopaths, Physicians, Public Health Nurses, Veterinarians.)
Once a target population
has been identified, the planner attempts to determine perceived or
felt needs of the audience in the areas of awareness, knowledge, skills
and opportunities (health infrastructure). It is also at this point that
it is crucial for county level agents to initiate meetings with local
groups, companies, and/or individuals in the target population in order
to determine the felt needs.
While validated survey
tools to determine felt needs are available, other effective, simple techniques
can be used. To identify felt needs, interview key natural and official
leaders of the targeted group, asking them to describe the open and hidden
health behaviors of the group, valued and condemned health behaviors,
and how the group defines itself, what the group "knows", and
how it came to know "it". A focus group of the targeted audience,
asking for the same information, may elicit different responses.
A verbal or written
survey of the targeted audience may provide even more information about
felt needs. Sample survey questions are included to illustrate the type
of social information that will limit or enable the success of a health
education project1:
- Identify the level
or levels of the program outcome desired:
- Individual
changes in behavior
- Social changes
in working with other agencies
- Service delivery
changes in the structure of any agencies
- Community changes
in problem-solving ability
- Give any network
intervention strategies which will be used, such as:
- Strengthen
existing networks
- Enhance the
total network
- Organize new
community efforts
- Identify any existing
social structures which will be targeted specifically to begin change:
- Family and
friends
- Neighborhoods
- Religious organizations
- Social organizations
- Civic organizations
- Service organizations
- Businesses
- Other
- Give support functions
and list human and financial resources which are available to reach
the goals and objectives of the program.
- Emotional (Listening,
showing trust or concern)
- Instrumental
(Real help in the form of labor, time, or money)
- Informational
(Providing advice, suggestions, directives, or referrals)
- Appraisal (Affirming
and giving feedback to each other)
1This
list of the social aspects of programs is based upon a planning process
model by Eng and Young (1992) for use in lay health advisor programs.
It has been adapted for use in the Extension Health Education Model. See
Health Education Behavior Models and Theories
for more information.
The felt or perceived
needs are compared with the real or service needs to determine
high priority health education needs. Real/service needs are those which
are determined by health officials and are supported by the available
data already examined. Those needs which are identified by officials,
data and demographics as high priority, high rate of occurrence and
which are perceived as important to the target audience, should be discussed
further.
The task assessing
needs and identifying programs in health can be facilitated through the
use of any available Extension Service Community Development resources
and materials on Community Strategic Health Planning. Examples of Extension
Service Health Strategic Planning materials are listed with contact information
in Appendix D.
Health is part of
the overall quality of life and economic well-being and, should be an
important component in any community development effort. Moreover, community
development professionals are experienced in facilitating local groups
such as task forces, committees, volunteer projects, and coalitions to
accomplish goals. Where such efforts are on-going, it should be fairly
easy to include a health education component in the effort, if such a
component does not already exist.
One way to build local
health groups would be to apply the Community Wellness Model2,
a four-stage model, which uses progressive involvement by members of the
community in a problem-solving approach. An example of the Community Wellness
County Health Profile is included in Appendix C-PART II. The County Health Profile includes some of the elements of the
Health Education Model Background Investigation and Program Identification,
and has been used effectively in many Extension Services efforts.
2Community
Wellness is a process-oriented program designed by Dr. Susan Jenkins during
her employment as a Community Development Specialist with the Georgia
Cooperative Extension Service. Details of this community-based model are
located in APPENDIX A, Part II.
Goals, Objectives,
Impact Indicators, and Evaluation Methods can be developed by the planners
after the process has targeted an audience and identified a potential
health education program/or project.
A goal in health education
can be identified as a desired behavior or health task. It should
be the type of broad goal illustrated by the three major Decisions for
Health goals which are included in the resources section of this model.
Each goal is achieved through an action plan of measurable, quantifiable
objectives which can be accomplished within a specified time frame. Examples
of a set of goals/ objectives might be:
Health Task:
People will stop using tobacco products.
Objectives:
Extension Agents will design and implement lay health advisor training
on tobacco cessation techniques to 24 lay health advisors in the month
of October. Each trained lay health advisor will provide social support
and information about tobacco cessation to 10 tobacco users over the months
of October and November. Local media will collaborate with health organizations
to conduct an intensive tobacco cessation awareness campaign beginning
in November and culminating on November 19th with the Great American Smokeout.
Impact Indicators:
- The percent of
smokers who enroll in stop smoking clinics (within some defined group
or area) will increase by 30 percent by December, and
- Three years after
the end of the program, the percent of individuals who smoke (within
some defined group or area) will be 10 percent lower than before the
program.
- Six month follow-up
contact of tobacco users who have been supported by lay health advisors
will reveal that 10 percent have ceased to use tobacco.
Evaluation Methods:
- Advance contact
and request for participation data of tobacco cessation programs.
- Review of epidemiological
data such as the Health and Human Services survey, BRFFUS.
- Six month follow
up phone call to lay health advisor contacts by an objective third party.
Once goals and objectives
have been identified, along with the criteria and methods for judging
impact (evaluation), the planning group should take a fresh look at the
overall direction. For any given set of objectives, there are numerous
possible programs. For the person(s) attempting to design such programs
and curricula, there are several questions which should be asked and answered
in determining the viability of such a program before work begins on the
actual program. One way of summarizing the work that has been done to
this point and answering these questions is the project brief.
The general format of such a project brief includes the health task or
broad goal,a brief (25 words or less) description of the program/project
which includes relevant data,geographical scope, time frame, and the goals
and assessed needs for awareness/knowledge,skills,and opportunities,a
description of the target population, demographic and supporting data,impact
or outcome indicators with specific criteria and time frame,limiting and
enabling factors such as human and financial resources,attitudes,cultural
factors,available materials, the educational content,and delivery and
evaluation methods.
When project briefs
have been completed, some projects will immediately appear not to be viable
because of constraints, costs, lack of human resources, or other reasons.
The number of projects which survive should then be prioritized based
upon likely effects and cost effectiveness. Prioritization, along with
total available resources, will finally indicate which and how many projects
should be pursued.
Project implementation
follows the project planning phases and has standard elements which are
not enumerated here. Appendix E provides a list of ideas for educational
delivery methods.
Process evaluation, the
first level of evaluation, should be an ongoing part of the "process"
of developing the program. However, once the project has been completed,
it is necessary to evaluate the immediate impacts of the program according
to the established and measurable objectives. These objectives may be evaluated
by an appropriate method, such as a survey of knowledge, the number of people
using a new service,and/or a change in observable behavior. Include any
follow-up that is needed, such as a survey by mail or by telephone. At the
final level, the longer range outcomes of the program should be considered.
At this stage, the data gathered on the health status of the target population
and any other quality-of-life social indicators (eg. illegitimacy, welfare,
self-esteem, discrimination, happiness) obtained early in the planning process
can be compared to the most recent data available. The evaluation of the
program may lead to additional projects, modifications in other programs,
or a modification in the goals or objectives. (For additional information
on evaluation, see the PRECEDE-PROCEED model
or the FORECAST model.
A step-by-step question
approach which might be helpful in impact evaluation could include the
following:
- What specific objectives
did you set for your program?
- What were the means
specified in order to achieve those objectives?
- What criteria were
established to determine whether or not each objective was achieved?
- Overall, what percentage
of your objectives did you achieve? (You may wish to weigh some objectives
as greater in importance than others.)
- Given your successes
and failures, should some of your objectives be considered unattainable,
or should you change the means and/or criteria?
- Given your responses
to #4 and #5, what goals should be or need to be reformulated?
- Given your responses
to the above six questions, how should you modify and revise the program/project?
Evaluation is an ongoing
process that can interact with other elements of planning, assessment
and implementation at several points, as illustrated in the diagrammatic
Extension Health Education Model. Other resources dealing with evaluation
are included in the resource Appendix F.
