Nursing researchers are advised to consider the reliability and validity of psychologic instruments used in research; however, evaluation of physiologic, or clinical, instruments is not always given the same attention. Reliability and validity issues related to physiologic measures will be discussed. Terms commonly used for the evaluation of physiologic instruments, such as "accuracy," "precision," and "sensitivity," will be explained, with parallels drawn to traditional measurement terms. Sources of potential measurement error, such as environment, user, subject, machine, and interpretation error, will be explained and specific examples given from cardiopulmonary nursing research.
建议护理研究人员考虑研究中使用的心理测量工具的信度和效度;然而,对生理测量工具或临床测量工具的评估却并非总能得到同样的重视。本文将讨论与生理测量相关的信度和效度问题。文中将解释常用于评估生理测量工具的术语,如“准确性”“精密度”和“灵敏度”,并与传统测量术语进行对比。还将解释潜在测量误差的来源,如环境、使用者、受试者、仪器及解释误差,并给出心肺护理研究中的具体实例。
