Adaptation 

Synonyms: Customization and Localization, Program Adaptation

Approach 

A strategy used to address a specific health problem within a particular population. It refers to the "how" of programming choices.

For example, there are many ways to deliver an educational program. These might include using mass media campaigns or educating patients in a clinical setting.

Approach: Insufficient Evidence 

This is a term used in the Guide to Community Preventive Services [link (will open in a new window)]. It indicates a body of evidence that does not give the Task Force [definition] enough information to decide whether or not an intervention is effective. A finding of "insufficient evidence" means that there's a need for more research into how effective the approach is. It does not mean that the approach doesn't work. It means that we aren't able to tell whether or not it works.

Related term: Community Guide

adapted from the Guide to Community Preventive Services

Approach: Recommended 

This is a term used in the Guide to Community Preventive Services [link (will open in a new window)]. It indicates a body of evidence that the systematic review of available studies provides strong or sufficient evidence that the approach is effective. The findings do not directly relate to how well the approach is expected to work.

A finding of "recommended" is based on several things. These include the study design, the number of studies, and how consistent the effects are across the studies.

Approach: Recommended Against 

This is a term used in the Guide to Community Preventive Services [link (will open in a new window)]. It indicates that a systematic review of available studies provides strong or sufficient evidence that the intervention is harmful or not effective.

B

Baseline 

Basic information that is collected before a program starts. The information can be used later to provide a comparison when evaluating the impact of the program. Baseline information can also be used to provide data about a starting point before a policy change or other change in a community.

Related terms: Post-test, Endpoint

Best Practices 

From a clinical perspective, this term can mean best screening or treatment options. From a health education or communication perspective, it can refer to using the best methods for delivering messages that have the greatest impact.

C

Community Guide 

A shortened name for the Guide to Community Preventive Services, a free resource of the Centers for Disease Control and Prevention. The Community Guide web site [link (will open in a new window)] offers reviews of different approaches you can use to influence a population's health. It also tells you which approaches have been most effective.

Community-based Participatory Research 

Community-based participatory research (CBPR) is a collaborative and participatory process that involves all partners and recognizes the strengths that each brings. CBPR starts with a research topic that is important to the community. The community helps with creating the research questions and interpreting the results. The goal is to combine knowledge with action, and to use the results to improve health outcomes and eliminate health disparities.

Core Components 

The key pieces of a program or intervention that make it work. If you change or remove them, you can't be sure that the program is still evidence-based.

Customization and Localization 

The process of changing an existing program for new audiences, conditions, or contexts that it was not originally created for. You can change the program to give it more impact and make it more relevant for your community. But remember, in order to make sure the program stays evidence-based, it's best to keep these changes to a minimum.

Common elements to change include:

  • language of the program
  • cultural references
  • reading level of materials

Synonyms: Adaptation, Program Adaptation, Program Customization/Localization




D

Data 

For program planning, data are numbers and facts that can be used to describe a specific population at a moment in time. Data may be used to assess the needs of a population that a program is targeting. Data may show the impact of a program on a population. Data may also be used to evaluate whether or not a program has met its objectives.

Specific types of data include:

Direct Observation 

Watching people in a natural setting without interacting. An example would be watching shoppers in a grocery store to see if they are reading posted nutritional charts.

E

Endpoint 

Synonym: Post-test

Related term: Baseline

Evaluation 

The systematic collection of information about the activities, characteristics, and outcomes of a program. The evaluation allows those delivering the program to make judgments about the program and improve its effectiveness. It may also help them as they make decisions about future program development.

Related terms: Outcome Evaluation, Process Evaluation

adapted from NCI's Using What Works

Evaluation Plan 

A written document that describes the overall approach or design that will be used to guide an evaluation. It includes what will be done, how it will be done, who will do it, and when it will be done. It also outlines why the evaluation is being conducted and how the findings will likely be used.

adapted from CDC's Evaluation Manual: Glossary and Evaluation Resources [link (will open in a new window)]

Evidence 

Information that helps determine whether or not a belief or statement is true. It is gathered systematically and goes beyond personal beliefs and opinions. It should be up-to-date and accurate.

Evidence-based Medicine 

Evidence-based medicine is the conscientious, explicit, and careful use of current best evidence in making decisions about the care of individual patients. The practice of evidence-based medicine means combining individual clinical expertise with the best available external clinical evidence from systematic research.

adapted from Sackett, D., Rosenberg, W., Muir Gray, J., Haynes, R. Richardson, W.  (1996). Evidence-based medicine: what it is and what it isn't.  British Medical Journal, 312, 71-72

Evidence-based Program 

A program that has been:

  • implemented with a specific group
  • tested and evaluated
  • found to be effective (brings about intended health changes)

For more about EBPs and why to use them, read About Evidence-based Programs [theory].




F

Fidelity 

Synonym: Program Fidelity

Focus Group 

A form of qualitative research in which information is collected from a small group that represents a wider population. The focus group allows researchers to learn about participants' perceptions, attitudes, and opinions on an issue or product. The open discussion format is well-suited to exploring new ideas and questions.

Related term: Qualitative Data

adapted from NCI's Using What Works

Formative Evaluation 

A way to look at a community and understand the interests, attributes, and needs of different populations and people in the community. It is also a way to understand the way these characteristics affect their behavior. This kind of research is done before a program is chosen and delivered, and it serves as the basis for developing effective strategies. For example, a community agency may use this kind of research to identify and understand the biggest needs of community members who are at greatest risk for HIV.

H

Health Disparities 

Differences in health status, health outcomes, health care access, and quality of health care among groups based on attributes like race/ethnicity and socioeconomic status (SES). Typical measures of health disparities include population-specific differences in the presence of disease, health outcomes, or access to health care.

I

Implementation 

Synonym: Program Delivery

In-depth Interviewing 

A method of collecting detailed information through individual interviews. Varies from brief, casual talks to long, formal conversations with members of your audience. In-depth interviewing relies on the interviewing skills of the researcher, including phrasing of questions and how much he or she knows about the subject's culture or frame of reference. Responses gathered in an interview are assumed to be true.

adapted from NCI's Using What Works

Indicator 

A measure of quantifiable data (information that can be captured in a number) related to an issue. This number can then help you decide how to address that specific issue.

For example, a program designed to help people quit smoking will probably ask participants whether they are smokers. The number of people who say yes or no is an indicator of how big the need is to address this issue. Also, comparing the number of yeses at the start to the number at the end is an indicator of the overall success of the program.

Intervention 

Synonym: Program




K

Key Informant Interviewing 

The process of interviewing influential, prominent, and well-informed members of a community. Community leaders are one such example. The social, political, financial, or management position of the interviewees may provide program planners with information they could not otherwise learn. For example, key informants may have a more objective opinion of a health issue if they are not personally affected by the issue.

Related term: Qualitative Data

L

Literacy Level 

Synonym: Readability

Literature Review 

A summary of published information about a particular topic. This type of document summarizes the current research. It can be helpful for gathering background information, writing grants, or planning programs.

Logic Model 

A program logic model is a picture of how a program works.  The model links program activities and processes with outcomes (both short- and long-term) and includes information about the theory and assumptions that drive the program.  A logic model often includes key factors (that support or limit program effectiveness), activities (events, methods, or actions), results of program activities, outcomes (such as changes in knowledge, attitude, or behavior), and impacts (at the organization-, community-, or system-level).

N

Needs Assessment 

The process of collecting and evaluating information about a particular population, organization, or community. This information is focused on specific and measurable problems, challenges, or needs of that group. Some examples of topics for needs assessment include:

  • patient health knowledge
  • community perceptions
  • provider attitudes
  • institution practices

You can use the information from a needs assessment to design health programs that are tailored to the group's needs.

O

Objective 

More specific than a goal, an objective states how much of a goal will be accomplished within a certain time frame. A program objective may describe the actual knowledge, behavior, attitude, or skill changes that result from the program. It may also detail a desired outcome including:

  • who is responsible
  • how much of a particular action they need to demonstrate
  • a time frame in which they must demonstrate it

Objectives should be SMART:

  • Specific
  • Measurable
  • Achievable
  • Realistic
  • Time-framed
adapted from NCI's Using What Works

Outcome Evaluation 

An evaluation to see if the objectives of a program were met. Evaluation measures can include changes in your target audience's knowledge, attitudes, and behaviors. For example, the evaluation may show an increase in physical activity among people who attend a program that promotes exercise.

Related terms: Evaluation, Process Evaluation

adapted from NCI's Using What Works

Outcomes 

Outcomes are events, occurrences, or conditions that show progress toward achieving the purpose of the program. Outcomes reflect the results of a program activity compared to its intended purpose. Outcomes are often expressed in terms of knowledge, skills, or behaviors. They are distinct from measures that reflect the delivery of the program (such as the number of participants).

Related term: Outcome Evaluation

P

Packaging 

Parts of an evidence-based program that can be changed to make the program more relevant to a particular community, population, or situation. Packaging can also be changed to increase the program's impact. As always, these changes must be kept to a minimum to ensure the program stays evidence-based.

Partnership 

A relationship that brings individuals and groups together to serve as resources for each other. Partnerships also allow both parties to better achieve a common goal.

Peer-reviewed Journal 

A publication in which articles on a particular subject are reviewed and edited by a panel of experts on that subject.

adapted from NCI's Using What Works

Pilot Test 

The process of doing a trial run of a program (or program materials) with a small group of people from the target audience. It allows you to confirm that the program or materials work with this group. A pilot test also lets you find problems with the intervention, so you can make changes before you deliver it on a larger scale.

adapted from NCI's Using What Works

Plain Language 

Communicating with an audience using language they can understand the first time they read or hear it. This might include:

  • avoiding specialized terms
  • defining specialized terms that must be used the first time they are mentioned
  • crafting messages with short, direct sentences, and short paragraphs

Post-test 

Basic information that is collected at the end of a program. It is compared to the baseline to show the effect of the program. It can also be used to provide data about the effect of a policy change or other change in a community.

Synonym: Endpoint

Related term: Baseline

Primary Data

Q

Qualitative Data 

Data collected in ways that typically encourage discussion, rather than one- or two-word responses. Qualitative data allow you to identify themes or fundamental concepts that provide a general way to understand the specific experiences of individuals. These data usually do not include numbers. They cannot be easily summarized in a table or graph.

Related terms: Data, Primary Data, Secondary Data, Quantitative Data

adapted from NCI's Using What Works

Quantitative Data
