Training Objectives
Participants can explain and apply these concepts:
o A survey is like a conversation o The 1st step of developing a survey is
end-use strategizingo The aim of survey design is to reduce
non-response and measurement error
4
A survey is like a conversation in that…
o Is communication with a purposeo Begins with an introductiono Needs to capture respondent’s interesto Starts with easy-to-answer ?s, builds to more
substantialo Follows logical order, uses transitions to change
topico Finds a delicate way to raise sensitive issueso Winds down with less consequential subjecto Indicates end with a sign off

What Surveys Can Tell You
To inform your project about
o Need for education or outreach
o Community priorities or policy options
o Level of support or opposition among stakeholder groups
o Makeup of local populations
o Extent of any change effected
o Satisfaction with services
7
Thinking about What Information to Collect
8
Using Reverse Logic to Develop Questions
Apply process to evaluation planning and development of data collection instruments
o Purpose of datao Target audience for the datao How information to be usedo Likely criticso Credibility thresholdo Pieces of datao Data sources and formats
9
How It Works
o An example o Try it out – pair activity
o Think of the project you work on and how a survey could inform your efforts
o Discuss with your team what you might want a survey to tell you, how it could be used
o Work together to fill in each of the boxes of the End-use Strategizing worksheet
10
Questions –Information Types
o Attitudes—What one wants or prefers
o Beliefs—What one thinks to be true
o Behavior—What one does or has done
o Attributes—What one is
11
Questions—Structure Types
o Open-ended—No answer choices are offered
o Closed-ended—Answer choices are offered
12
Open-Ended Questions
Examples:o Short Answer
o How long have you lived in this apartment?
o Clarification (as part of skip pattern)o If you answered “yes” to the previous
question, please explain why... o Comments
o Please write any additional comments you may have about the potential smoke-free policy.
13
Open-Ended Questions
Drawbacks:o Respondents may find it difficult to
express their feelingso They take more time o Can yield inadequate answers without
probing, follow-up questionso Analysis is time consuming and
difficult
14
Closed-Ended Questions
Examples:
o Yes/No questions
o Have you used any tobacco products in the last 30 days? Yes No
o Multiple Choiceo How many bedrooms does this apartment have? Zero (Studio) One Two Three Other _________________
15
Closed-Ended Questions
o Likert-type Scaleso To what degree would you favor or oppose a
policy to make at least half of the individual units in this apartment complex non-smoking?
o How often do you attend coalition meetings?
Strongly Favor
Somewhat Favor
Neither Favor nor
Oppose
Somewhat
Oppose
Strongly Oppose
1 2 3 4 5
All of the time
Most of the time

Rarely Never
1 2 3 4 5
16
Closed-Ended Questions
Examples (continued):
o Ranking
o On a scale of 1 to 5, rank the issues that matter most to you with 1 being most important.
___ Health care
___ Environmental protection
___ Safe neighborhoods
___ Quality of education
___ Fair wages

“Survey design is all about motivating people adequately so they complete the cognitive steps necessary for answering
questions accurately and return the questionnaire.”
~ Don Dillman
18
The Dillman Principles
o The aim of survey design is to minimize measurement and non-response error
o Measurement error: poor question wording or formatting leads to inaccurate answers
o Non-response error: people who respond to the survey are different from those who did not
Don A. Dillman. 2007. Mail and Internet Surveys: The Tailored Design Method, 2nd ed. Hoboken, NJ: John Wiley & Sons.
19
Creating Respondent Buy-in
o Motivate people to begin and complete surveyo Use introduction/cover lettero Give compelling reason to participateo Ask interesting first question
o Build trust by demonstrating competenceo Employ good survey designo Make it easy to understand what to do

Example Introductions
1. The Bonanza County Public Health Department is interested in finding out about how tenants feel about being around tobacco smoke. There are no right or wrong answers and they will be kept anonymous. We hope you will share your opinions with us.
2. To help protect Bonanza County multi-unit housing (MUH) residents from the dangers of secondhand smoke, the county Tobacco Prevention Program will be working with MUH owners and managers to adopt and implement a voluntary policy that prohibits smoking in…
3. The Bonanza County Tobacco Education Coalition is seeking public opinion on the effects of exposure to secondhand smoke and possible smoking policies. Your opinions are very important to us.
4. Smoke-Free Apartment Complexes – Tenant Survey
21
Managing Cognitive Energy
o Respondents will devote only a limited amount of mental effort to complete your survey
o Make survey easy to understand, navigate and respond to
o Cluster related topicso Cluster similar response typeso Weigh need for survey length vs.
complexity of questions
22
Keep Population of Interest in Mind
o What cultural characteristics might affect their ability to understand the survey?
o What is their literacy level? o What language do they feel most
comfortable with? o How much time will they be willing to spend
on taking the survey? o Is this a topic that interests them?
23
Dillman #1: Keep It Simple
o Choose simple rather than specialized words
o Use as few words as possibleo (Sometimes these two rules conflict)
Use Rather Than
Customers Patrons
Smoke from other people’s cigarettes
Secondhand smoke
Apartments or condominiums
Multi-unit housing
People who live here Occupants of this household
24

all parks non-smoking?
o Balance scales with equal number of positive and negative choices
o Very likely, somewhat likely, not very likely
o Neutral position is different from undecidedo Neither supportive nor unsupportive vs. don’t
know
Problematic:
27
Balancing Act Example
Good Example:
To what extent do you agree or disagree with the statement “Smokers have a right to smoke”?
Strongly agree Somewhat agree Neither agree nor disagree Somewhat disagree Strongly disagree I don’t know
28
Dillman #5: Pick Me!
o Beware of primacy effects in “mark all that apply” lists
o Lists are OK for factual questions but not attitudes or preferences
o Make each issue a yes/no or scalar question
1. Which type of organization do you represent in the coalition? (mark all that apply)
Local lead agency Service organization Law enforcement Educational institution Other ____________ I don’t represent an
organization
Ok for list
29

32
Framing Sensitive Issues
o Save more sensitive questions towards the endo Once you’ve established a rapporto In case respondents refuse to proceed
o Soften the impact of potentially objectionable questionso Preface personal questions with more
general ones about the issue or ask about other people
33
Problematic:
1. Have you ever shoplifted any tobacco products from a store?
Revised Versions:The questions which follow are being asked to help us understand where young people get tobacco products when they are underage. We really appreciate your help and that of students all over the state who have been asked to complete this survey honestly.

V2. Have you ever obtained tobacco products from…
a friend or relative? yes noa store without paying? yes no

o Avoid excessive specificityo How many cigarettes have you smoked
within the last 30 days?
36
It Doesn’t Add Up continued

______ months
37
Dillman #9: Don’t Be Negative!o Avoid asking respondents to say “yes” in order
to mean “no”
Problematic:
In which areas of the apartment complex should people not be able to smoke?
Revisions:
v1 Which areas of the apartment complex would you like to be non-smoking?v2 In which areas of the apartment complex should smoking be prohibited?
38
Dillman #10: Over a Barrel
o Avoid double-barreled questions where two things are being asked in the same question
o Watch out for “and”o Instead collapse into illustrative
category, split into two questions, use “or”
39
Over a Barrel?
Is either of these double-barreled?o If the downtown area was free of
secondhand smoke and cigarette litter, do you think you would be more or less likely to shop and attend events there?
o Do you think retailers should have to pay for a license to sell tobacco which would earmark a portion of the funds to cover the expense of enforcement?
40
Now You Try it
o Write one question using each of these formats:o Yes/noo Multiple choiceo Scalar o Open-ended
41
Survey Design Considerations
o Create a clear navigational patho Provide signposts to guide respondentso Use graphic elements as clues
START ❶ Circle the response
o Keep format visually uncluttered
42
Survey Design Considerations
o Cluster like topics (e.g., knowledge, preferences, support)
o Also cluster similar response formats (Likert scales, statements of agreement, etc.)
o Use consistent scale directions throughouto Organize choices vertically, not
horizontallyo Beware of response set effecto Use pamphlet layout
43
44
Sequencing Questions
o Remember a survey is like a conversation
o First engage interest, build trust, ensure success
o Move from easy-to-answer to complexo General to more specifico Less personal to more sensitiveo Balance open-ended vs. closed-endedo Save demographic questions for the end
