Survey Design

The primary objective of cognitive interviewing, also known as cognitive testing, is to understand the cognitive mechanisms underlying the survey-response process. An equally important aim is contributing to the development of best practices for writing survey questions that are well understood and that produce low levels of response error. In particular, an important applied objective is the evaluation of a particularset of questions, items, or other materials under development by questionnaire designers, to determine means for rewording, reordering, or reconceptualizing. Hence, as well as providing an empirical, psychologically oriented framework for the general study of questionnaire design, cognitive interviewing has been adopted as a 'production' mechanism for the improvement of a wide variety of survey questions, whether factual, behavioral, or attitudinal in nature.
