目的 探讨认知性访谈在经皮冠状动脉介入治疗（percutaneous coronary intervention，PCI）术后患者健康促进行为意向量表编制中的应用效果。方法 2023年12月至2024年1月，采用目的抽样法，以最大差异策略选取大庆市2所三级甲等医院心内科收治的26例PCI术后患者进行3轮认知性访谈，依据问题评估系统（question appraisal system，QAS-99）对访谈结果进行整理、编码，结合编码结果修订量表。结果 第1轮访谈，受访者对10个条目提出疑义，其中7个条目与“澄清”有关，3个条目与“假设”有关，1个条目与“知识/记忆”有关，经讨论后对条目修改；第2轮访谈，1个条目有“措辞”问题，经讨论后修改；第3轮访谈，受访者均能正确理解条目内容且未提出疑义，访谈结束。结论 认知性访谈有效解决了量表编制过程中编制者与受试者、受试者与受试者之间的认知差异，提高了量表的准确性、适用性和科学性。

Objective To explore the effectiveness of cognitive interviews in the development of the Health Promotion Behavior Intention Scale for post-percutaneous coronary intervention(PCI) patients.Methods From December 2023 to January 2024,26 post-PCI patients from two tertiary A hospitals in Daqing were selected using purposive sampling with a maximum variation strategy.Three rounds of cognitive interviews were conducted.The results were organized and coded using the Question Appraisal System (QAS-99)，and the scale was revised accordingly.Results In the first round，respondents raised concerns about 10 items:7 related to “clarity”，3 to “assumptions”，and 1 to “knowledge/memory”.These items were revised after discussion.In the second round,1 item had a “wording” issue and was revised.In the third round，respondents correctly understood all items，and no further concerns were raised，concluding the interviews.Conclusions Cognitive interviews effectively addressed cognitive differences between developers and respondents，improving the scale’s accuracy，applicability and scientific validity.
