We distinguish between open questions, in which the respondent uses their own words to answer, and closed questions which provide pre-written response categories.
CLOSED QUESTIONS:
|
|
Closed questions should be unidimensional: they ask about one and only one topic at a time. Questions which use more that one dimension are called “double-barreled”.
Rule 1: Avoid double-barreled questions. We cannot disentangle which question embedded in a question the respondent actually answered. Double-barreled questions are usually quickly recognized by their use of “and” or “or”. But any question that simultaneously asks about at least two topics is double-barreled.
TWO BAD DOUBLE-BARRELED EXAMPLES:
Do you agree that we should lower property taxes AND provide more county services?
Do you approve or disapprove of abortion in cases of incest OR threats to the mother’s health?
I have seen questions so convoluted that they were actually quadruple-barreled items, asking FOUR questions in one!
Rule 2: PROVIDE ALL RESPONSES TO A CLOSED QUESTION.
EXAMPLE: For marital status, people are married, widowed, divorced, separated, living together, single (NEVER MARRIED) or something else (you’d be surprised), not just married or single.
Rule 4: Avoid condensing numerical responses into grouped categories.
The exception: income categories. We use grouped categories to provide greater confidentiality in the answers and because people generally only know their incomes around April 15.
Rule 5: Use a mix of question formats to avoid format response sets or response effects.
For example, one of the most popular formats is the Likert item: people are asked whether they strongly agree, agree, are undecided, disagree, or strongly disagree with an attitude statement. Many survey researchers love Likert items because you can administer them quickly (a well-trained interviewer can do five per minute) and they are easy to code. BUT:
Don’t just use Likert agree-disagree
questions. This encourages acquiescence response set. And, acquiescence
response set is negatively related to education. College educated respondents
are "nay-sayers."
|

In acquiescence response set, people tend to generally agree or disagree with nearly every sweeping attitude statement put before them in a questionnaire. Well-educated persons have been taught "never say 'always' or 'never,' " so "nay-saying," or disagreement, rises with education, typically regardless of content. We are less clear about which factors nudge people to gravitate toward extreme responses ("strongly agree" or "strongly disagree") or toward the middle, but we know that it happens too.
The tendency to simply respond "I don't know" is also linked to education. In a recent article, I found that people who had not graduated high school were three times as likely to give "I don't know" responses as people who had graduate school experience. Women were nearly twice as likely as men to say "I don't know." In such cases, you need to reflect on whether a "don't know" response truly represents lack of knowledge or some other factor (e.g., low self-efficacy).
BEWARE: "Standardized tests" which contain long sets of items, all with identical response formats, are especially prone to response sets. This is especially true if all items take a Likert-type format. In addition, "personality inventories" which contain long sets of identically phrased items (e.g., "A lot like me," "Somewhat like me," "A little like me," or "Not at all like me") are also subject to response format effects. Unfortunately, a definite, but unknown, specific amount of "reliability coefficients," such as coefficient alpha, is undoubtedly due to the fact that correlations among the items occur because of response set. Interesting...but probably not what you hoped for.
WHAT YOU CAN DO: Vary the item format that you use. Keep Likert items to a minimum. Try to include reversed items, or the same concept using different formats, in your questionnaire. Pilot test your questionnaire ALOUD even if you plan it to be self-administered. See if you detect respondents consistently falling into response patterns ("yep..." "yep..." "yep..") and "clean up" the problem areas.
Using experimental
"split-ballot"
techniques, survey researchers also assess whether different forms of a
question yield comparable responses and appear to be comparable in meaning.
Subsamples from the total survey are selected at random to receive the
"same item" with different question wording. We check not only to see whether
the univariate frequency distributions are the same, but also whether question
wording changes how one concept relates to other variables, such as educational
level.
Rule 6:
IN GENERAL: don’t use hypothetical situations. Don't ask respondents
to guess how other people “would feel” or even how they would feel under
hypothetical conditions. The answers are generally unreliable because people
have not thought about their responses. Most people would have a hard time
telling you exactly how they would feel “if” they found out their spouse
was unfaithful--except “bad” (and we don’t need a survey to figure that
one out).
Rule 7: Try to keep the number of response alternatives that are read to respondents to a maximum of seven. You cannot use show cards in a telephone survey. The respondent must be able to memorize the alternatives, then select one. The fewer the response categories, the easier this is.
Rule 8: Use specific time frames when you ask about behaviors, particularly regular or habitual behaviors. Don’t leave the time frame vague or undefined if at all possible.
“During
the last month, how many times did you attend religious services?”
“During
the last week, did you smoke any cigarettes at all?”
Rule 9: Similarly, use specific place frames. Do you want to know where someone was born? (In Detroit, in a hospital, in the United States, under the kitchen table.) If you want to know someone's country of birth, ask "In which country were you born?"
Rule 10: Make sure to make the question stem consistent with the provided responses.
EXAMPLE: If the stem reads “how often”, make sure the responses are in a time frame (times per month) or take a relative form such as “All of the time”“Most of the time”“Half the time”“Seldom” or “Never”.
Reserve “yes/no” questions (“...did
you smoke any cigarettes at all?”) for specific actions or dimensions of
an issue.
Rule 11:
If you have a very complicated question stem, break the question into AT
LEAST two questions. The respondent will have an easier time
and the questionnaire will actually go faster.
BAD QUESTION: “What do you think should be done about the environment? Tell me all the actions that you approve: A. Recycling B. Start carpools C. Mandatory thermostat controls (etc.)”
BETTER SET OF QUESTIONS:
REMEMBER! Approve-disapprove response categories rank responses from highest to lowest (approve is more in favor than disapprove) and are ORDINAL-level variables.
Rule 12: Avoid jargon or technical terms. Your respondent probably won't know what "trait anxiety" is, even if she or he has a lot of it. "ET" to most people means a movie about a quaint alien, not Educational Technology.
Rule 13: Avoid "red flag" words, that is, words with emotional connotations or that coincide with strongly-held values.
Everyone wants to be "fair"! NEVER use that word in a question unless you are talking about a civic event or festival such as the North Florida Fair!
"Murder" is another red flag word (as
in "Do you approve of the murder of unborn babies?")

Rule 14:
If the questionnaire will be administered by an interviewer, be sure to
read the entire questionnaire aloud in a pilot test. Many words
sound alike that have different meanings. Consider:
|
|
|
|
|
|
|
|
|
Rule 15: Similarly, beware of words that have multiple meanings, for example: kind; fair; item. Put the Thesaurus in your computer's word processor to use!
Rule 16:
In fact, it is an excellent idea to pilot test
your questionnaire aloud no matter what. This is one of the
best ways to catch any problems with question wording.
|
|
Rule 17:
In an open-ended question, you want respondents to speak their minds.
So ask open-ended
questions in a way that encourages people to give a complete and full answer.
Use phrases
such as “what are”? “how do you feel about”?
Never
ask a “yes/no” open-ended question!
Good: “what
do you like best about high school cafeteria lunches?”
Bad: “do
you like high school cafeteria
lunches?”
Good: “what
do you think is the biggest issue with homeless people in Tallahassee?”
Bad: “is homelessness
a problem in Tallahassee?” (what is “problematic?”)
Rule 18: With
a complex question that could have multi-dimensional answers
(“what do you see as the top priorities for the Florida legislature this
year?”), use an open-ended format.
There will be so many possible responses you will not be able to specify
all the response categories in advance.
