Head and neck cancer: validation of a data collection instrument

ABSTRACT Objective: construct and validate the content of an instrument to collect data from patients with head and neck cancer (HNC) served in a specialty clinic. Method: methodological study consisting of four steps. The first step consisted in the preparation of the instrument using databases and the theoretical model of Marjory Gordon. In the second and third steps the content was validated by eight nursing judges. The evaluation used the Content Validity Index (CVI). The fourth step consisted in a pilot test with seventeen HNC patients. Results: of the 88 questions formulated and organized on the dimensions of structure and process submitted to validation, items with CVI lower than 0.80 were excluded. The final instrument was composed of 56 items, with global CVI calculated as 0.87. Conclusion: the final instrument presented content validity for data collection in head and neck clinic.摘要 研究目的：编制并验证一款用于专科门诊收治的头颈癌（head and neck cancer, HNC）患者临床数据收集的研究工具的内容效度。研究方法：本研究为方法学研究，共分为四个阶段。第一阶段：依托数据库及玛杰里·戈登（Marjory Gordon）理论模型完成研究工具的编制。第二、三阶段：邀请8名护理评审专家对工具内容开展效度验证，采用内容效度指数（Content Validity Index, CVI）进行评价。第四阶段：纳入17名头颈癌患者开展预试验。研究结果：本次研究共拟定88个按结构与流程维度组织的条目并提交效度验证，剔除内容效度指数低于0.80的条目后，最终研究工具包含56个条目，整体内容效度指数为0.87。结论：本研究最终编制的工具具备良好的内容效度，可用于头颈肿瘤专科门诊的患者数据收集。
