• Agreeing with assertions<br />

• Non-differentiation in ratings<br />

Other Issues<br />

• Double-barreled questions<br />

Bad Question:<br />

Compared <strong>to</strong> one year ago,<br />

are you paying more, less, or<br />

about the same for your au<strong>to</strong><br />

and life insurance?<br />

Better Question:<br />

Compared <strong>to</strong> one year ago, are<br />

you now paying more, less, or<br />

about the same for…<br />

a. au<strong>to</strong> insurance?<br />

b. life insurance?<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

16<br />

Other Issues<br />

• Specify who, what, when, where and how.<br />

• For example, whose income? What’s<br />

included? Over what period of time?<br />

• “In 2002, what was your <strong>to</strong>tal household<br />

income, before taxes? Please count income<br />

from all members of your household,<br />

including wages from employment, disability,<br />

social security, and public aid.”<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

17<br />

Other Issues<br />

Specify through cues<br />

• “People drink beer in many places – for<br />

example, at home, at restaurants, at bars,<br />

sporting events, at friends’ homes, etc.<br />

During the past 30 days, did you drink any<br />

beer?”<br />

Other Issues<br />

Use words with singular meanings<br />

Ambiguous:<br />

Clearer:<br />

How would you compare Compared <strong>to</strong> your last<br />

how close you are <strong>to</strong> family neighborhood, do you now<br />

in your current neighborhood live closer <strong>to</strong> your family,<br />

<strong>to</strong> how close you were in are you further from your<br />

your old neighborhood? family, or are you about<br />

Would you say your family is<br />

the same distance?<br />

closer here, further here, or<br />

the same?<br />

Response Options<br />

• Should be consistent with the question<br />

• Should typically be exhaustive, including<br />

every possible answer<br />

• Categories should typically be mutually<br />

exclusive (no overlap)<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

20<br />

Constructing Response Scales<br />

• 5-7 response options<br />

• Using graphic images, such as thermometers<br />

and ladders, and card sorting for complex<br />

ratings is effective<br />

• Number of points in scale should be<br />

determined by how you intend <strong>to</strong> use the<br />

data<br />

Numbering vs. Labeling<br />

• Numbers alone<br />

• Partial labeling<br />

• Full labeling<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

22<br />

Middle Category<br />

• Include or omit?<br />

• Common practice <strong>to</strong> omit<br />

• Few respondents are truly in the middle on<br />

any given issue<br />

• Evidence from empirical studies<br />

• Our usual recommendation is <strong>to</strong> include it<br />

unless there are persuasive reasons <strong>to</strong><br />

exclude<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

23<br />

Open vs. Closed Questions<br />

Open-Ended Questions<br />

• Suggest no alternatives<br />

• Probing<br />

• Extensive interviewer training<br />

• Elaborate coding schemes<br />

• Expensive and time-consuming<br />

• Free exchange of ideas without bias<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

Open vs. Closed Questions<br />

Closed-Ended Questions<br />

• Standardized questions and answers<br />

• Simple interviewer training<br />

• Easy <strong>to</strong> analyze<br />

• May make it <strong>to</strong>o easy <strong>to</strong> answer without thinking<br />

• May limit spontaneity<br />

• Not best when<br />

• asking for frequency of sensitive behaviors<br />

• there are numerous possible responses<br />

– role of initial question development and pretesting<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

25<br />

Good Questions<br />

• Use simple language<br />

• Try <strong>to</strong> use words with only one meaning<br />

• Ask questions about one object at a time<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

26<br />

Good Questions<br />

• Specify details - who, what, where, when<br />

• Use appropriate time frames<br />

• Provide cues <strong>to</strong> aid memory<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

27<br />

Good Questions<br />

• Use widely unders<strong>to</strong>od modifiers in response<br />

options<br />

• Use verbal labels<br />

• Use moderate number of response options (5-7)<br />

• Use evenly spaced response options<br />

• Show cards or repeat response options<br />

• Use pre-testing <strong>to</strong> understand cognitive<br />

processes & determine potential problems<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

28<br />

Good Questions<br />

• Minimize respondent cognitive<br />

burden<br />

• Avoid cues that Rs can use for<br />

satisficing (no opinion response<br />

options; agree-disagree questions)<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

29<br />

Question Order<br />

• Segment by <strong>to</strong>pic<br />

• Ask about related <strong>to</strong>pics <strong>to</strong>gether<br />

• Ask recall backwards in time<br />

• Use transitions when changing <strong>to</strong>pics<br />

• Give a sense of progress through the questionnaire<br />

• Leave objectionable questions (e.g., income) for<br />

the end<br />

• Put demographic questions at the end<br />

Evaluating Questions<br />

• Administration Difficulty<br />

• Reliability<br />

• Validity<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

31<br />

Conventional Pretest<br />

• Small sample of respondents<br />

• Train interviewers thoroughly<br />

• Experience level<br />

• Describe why the study is being done (briefly!)<br />

• Conduct interviews<br />

• Feedback from interviewers<br />

• Overall problems<br />

• Question-by-question problems<br />

• Suggestions for revision<br />

• Interviewer feedback useful even during main<br />

study<br />

<strong>Survey</strong> <strong>Research</strong> Labora<strong>to</strong>ry<br />

32<br />

Cognitive Interviewing<br />

• Think-aloud<br />

• To detect questions worded in problematic ways<br />

• lead respondents <strong>to</strong> infer meanings not intended by<br />

the researchers<br />

• make interpretation difficult and frustrating for a<br />

respondent<br />

• Respondents asked <strong>to</strong>…<br />

• Restate question in own words<br />

• Think aloud as they generate answer<br />

Cognitive Interviewing<br />

• Useful for identifying comprehension,<br />

retrieval, judgment, and mapping<br />

problems<br />

• Practice (with analyzing cognitive<br />

interview transcriptions) makes perfect<br />
