摘要:Although principal investigators [PI] have a variety of design techniques for strengthening the validity of questionnaires, they often lack the tools for interactive judgmental processing needed to verify the logical design relationships between questions that they used in designing the questionnaire. To facilitate this verification process, we use the PI’s judgment of what constitutes a logical response “mismatch” between questions as the catalyst for investigation that often leads to questionnaire redesign. Such logical response mismatches often occur when questions are mistakenly placed within opposing linguistic contextual spaces or simply do not clearly express the intended meaning—i.e., a lack of clarity. We present two simple techniques useful in identifying such mismatches and offer heuristics that may be used to rationalize taking corrective questionnaire redesign actions. We also provide a decision support system (DSS) based on a VBA-Excel macro that facilitates identifying such mismatches. The DSS is available upon request.
