There is not yet a universal system for describing the status of pressure sores. The purpose of this study was to assess the validity and reliability of an instrument developed by the researchers for evaluation of pressure sores, the Pressure Sore Status Tool (PSST). This study was part of a larger study, which included development of a theoretical model for creation of items for the PSST. A nine-member expert judge panel established content validity of items on the instrument. Data were analyzed using a content of validity index (average index for tool = .91) and judges' comments were used to modify two items on the PSST. Two Enterostomal Therapy (ET) nurses independently used the revised tool to rate 20 pressure sores on ten adult medical-surgical patients, at two observation times. Interrater reliability was established at r = .91 for first observation and r = .92 for the second observation (p < .001). Intrarater reliability was r = .99 for rater one and r = .96 for rater two (p < .001). Future research will focus on refinement and further reliability testing of the instrument.
目前还没有一个通用的系统来描述压疮的状况。本研究的目的是评估研究人员开发的一种用于评估压疮的工具——压疮状况工具（PSST）的有效性和可靠性。本研究是一项更大规模研究的一部分，该研究包括为PSST创建项目开发一个理论模型。一个由九名专家组成的评审小组确定了该工具项目的内容效度。使用内容效度指数（工具的平均指数为0.91）对数据进行分析，并利用评审人员的意见对PSST上的两个项目进行修改。两名造口治疗（ET）护士在两个观察时间点独立使用修订后的工具对十名成年内科-外科患者的20处压疮进行评分。第一次观察时评定者间信度为r = 0.91，第二次观察时为r = 0.92（p < 0.001）。评定者1的评定者内信度为r = 0.99，评定者2的评定者内信度为r = 0.96（p < 0.001）。未来的研究将集中在该工具的完善和进一步的信度测试上。
