Questionnaire DesignI. Clarify your study goal— Write down your study goal bef

Questionnaire Design
Good morning, everyone. Today we will continue our lecture on research methodology, particularly on questionnaire design. Most problems with questionnaire analysis can be traced back to the design phase of the project. Well-defined goals are the best way to assure a good questionnaire design. When the goals of a study can be expressed in a few clear and concise sentences, the design of the questionnaire becomes considerably easier. The questionnaire is developed to directly address the goals of the study. And I am going to present to you ten tips, which might help you design better questionnaires.
Let me begin with the first tip. One of the best ways to clarify your study goals is to decide how you intend to use the information.[1]You should do this before you begin designing the study. This sounds obvious, but many researchers neglect this task. Why do we do research if the results will not be used? Be sure to commit the study goals to writing. Whenever you are unsure of a question, refer to the study goals and a solution will become clear. Ask only questions that directly address the study goals. Avoid the temptation to ask questions because it would be "interesting to know".
Tip 2: Keep your questionnaire short. As a general rule, with only a few exceptions, long questionnaires get less response than short questionnaires. Response rate is the single most important indicator of how much confidence you can place in the results. A low response rate can be devastating to a study. Therefore, you must do everything possible to maximize the response rate. One of the most effective methods of maximizing response is to shorten the questionnaire. If your survey is over a few pages, try to eliminate questions. Many people have difficulty knowing which questions could be eliminated. For the elimination round, read each question and ask, "How am I going to use this information?"[2]If the information will be used in a decision-making process, then it’s important to keep the question. If not, throw it out.
Tip 3: Make the envelope unique. We all know how important first impressions are. The same holds true for questionnaires. The respondent’s first impression of the study usually comes from the envelope containing the survey.[3]The best envelopes, i.e., the ones that make you want to see what’s inside, are colored,[4]hand-addressed and use a commemorative postage stamp. Envelopes with bulk mail permits or gummed labels are perceived as unimportant. This will generally be reflected in a lower response rate.
Provide a well-written cover letter. The respondent’s next impression comes from the cover letter. The importance of the cover letter should not be underestimated. It provides your best chance to persuade the respondent to complete the survey.
Tip 4: Include clear and concise instructions on how to complete the questionnaire.[5]These must be very easy to understand, so use short sentences and basic vocabulary.[6]Be sure to print the return address on the questionnaire itself, since questionnaires often get separated from the reply envelopes.
Tip 5: Begin with a few non-threatening and interesting items. If the first items are too threatening or boring, there is little chance that the person will complete the questionnaire. People generally look at the first few questions before deciding whether or not to complete the questionnaire. Make them want to continue by putting interesting questions first.
Tip 6:[7]Use simple and direct language. The questions must be clearly understood by the respondent. The wording of a question should be simple and to the point. Do not use uncommon words or long sentences. Make items as brief as possible. This will reduce misunderstandings and make the questionnaire appear easier to complete.[8]One way to eliminate misunderstandings is to emphasize crucial words in each item by using bold, italics or underlining.
Tip 7: Leave adequate space for respondents to make comments. One criticism of questionnaires is their inability to retain the "flavor" of a response. Leaving space for comments will provide valuable information not captured by the response categories.[9]Leaving white space also makes the questionnaire look easier and this increases response.
Tip 8: Hold the respondent’s interest. We want the respondent to complete our questionnaire. One way to keep a questionnaire interesting is to provide variety in the type of items used.[10]Varying the questioning format will also prevent respondents from falling into "response sets". At the same time,[11]it is important to group items into coherent categories. All items should flow smoothly from one to the next.
Tip 9:[12]Provide incentives as a motivation for a properly completed questionnaire. What does the respondent get for completing your questionnaire? Altruism is rarely an effective motivator. Attaching a dollar bill to the questionnaire works well.[13]If the information you are collecting is of interest to the respondent, offering a free summary report is also an excellent motivator. Whatever you choose, it must make the respondent want to complete the questionnaire.
Tip 10: Pre-test your questionnaire.[14]The final test of a questionnaire is to try it on representatives of the target audience. If there are problems with the questionnaire, they almost always show up here.[15]If possible, be present while a respondent is completing the questionnaire and tell her that it is okay to ask you for clarification of any item. The questions she asks are indicative of problems in the questionnaire i.e., the questions on the questionnaire must be without any ambiguity because there will be no chance to clarify a question when the survey is mailed.
OK. I think I have covered the important tips for designing an effective questionnaire and how to present it to the targeted audience. Next time, we shall discuss how to sort out and classify data collected from the questionnaire.
