Complexity of the Questionnaire
- Although researchers generally attempt to minimize complexity, some subject areas still require relatively complex questionnaires.
- For example, the sequence of number of questions asked often depends on the answer to previous questions.
- A respondent seeing a questionnaire of this type for the first time can easily become confused or discouraged.
- Thus, computer, personal, and telephone interviews are better suited to collect this type of information than are mail interviews.
- Other aspects of complexity also tend to favor the use of personal or computer interviews. Visual cues are necessary for many projective techniques, such as the picture response.
- Multiple-choice questions often require a visual presentation of the alternatives because the respondent cannot remember More than a few when they are presented orally.
- However, most attitude scales can be administered via
- the phone.
- The telephone, and often mail, are inappropriate for studies that require the respondent to react to the actual product, advertising copy, package design, or other physical characteristics.
- Techniques that require relatively complex instructions are best administered by means of personal inter-views.
- Similarly if the response required by the technique is -extensive, such as with many conjoint analysis studies, personal inter-views are better, with computers second.
