Questionnaire development involves rigorous testing to ensure reliability and validity. Due to time and cost constraints of developing new questionnaires, researchers often adapt existing questionnaires to better fit the purpose of their study. However, the effect of such adaptations is unclear. We conducted cognitive interviews as a method to evaluate the understanding of original and adapted questionnaire items to be applied in a future study. The findings revealed that all subjects (a) comprehended the original and adapted items differently, (b) changed their scores after comparing the original to the adapted items, and (c) were unanimous in stating that the adapted items were easier to understand. Cognitive interviewing allowed us to assess the interpretation of adapted items in a useful and efficient manner before use in data collection.
问卷开发需要进行严格测试以确保可靠性和有效性。由于开发新问卷存在时间和成本限制，研究人员通常会对现有问卷进行调整，以更好地符合他们的研究目的。然而，这种调整的效果尚不清楚。我们进行了认知访谈，以此作为一种方法来评估对原始问卷项目和调整后问卷项目的理解，以便应用于未来的研究。研究结果显示，所有受试者（a）对原始项目和调整后项目的理解不同，（b）在将原始项目与调整后项目进行比较后改变了他们的分数，并且（c）一致表示调整后的项目更容易理解。认知访谈使我们能够在将调整后的项目用于数据收集之前，以有用且高效的方式评估其解读情况。
