Developing a questionnaire seems easy, right? Decide what you need to know, write a bunch of questions and get people to answer them. What you need to know, is that the responses people give are affected by the way you word each item or question. Many problems arise and much information is rendered useless because of inattention to the way items are worded during questionnaire design.

Item writing is affected by item wording (the term item is used because not all items on a questionnaire are questions). Questionnaire designers must consider the following: Does the item elicit information related to the topic of interest? Is wording clear and unambiguous? Will the item mean the same thing to everyone?

Does the item demand knowledge and information the respondent has (or not)? Does the item contain personal or potentially threatening issues the respondent might resist? Are items loaded with social (un)desirability? Often the approach to items and questions will differ depending on how the survey is administered.

Survey means ‘to look at in a comprehensive way’. There are numerous ways to look at issues in the world of survey research, including in-person and telephone interviews, mailed and online questionnaires.

In-Person Interviews

Getting information in person may be the most personal approach and most effective way of gaining trust and cooperation from the respondent. It is easier to react to puzzled facial expressions, answer questions, probe for clarification or redirect responses. Face to face contact is particularly useful to detect respondent discomfort when discussing sensitive issues or attempts to respond in a socially desirable way.

The in-person interview is usually more costly than any other method. Interviewers must be trained and flown to geographic areas or found and trained within the area of study. It may be unrealistic to send interviewers into areas of high density housing or high crime which may result in an important demographic left out of the study.
