Development of instruments to measure psychosocial variables is a complex process that begins with concept analysis and concludes with pilot testing to establish initial reliability and validity properties. Although the instrument development process is lengthy. PACU nurses are encouraged to follow all steps; if they do not, they will be unsure of what is measured or the meaning of the finding. Discussed here is the final phase of the instrument development process; calculating and analyzing construct validity and internal consistency reliability. An example is given that applies reliability and validity methods to a hypothetical instrument.
开发用于测量心理社会变量的工具是一个复杂的过程，始于概念分析，终于进行预试验以确定初始的信度和效度特性。尽管工具开发过程漫长，但鼓励麻醉后护理单元的护士遵循所有步骤；如果不这样做，他们将不确定所测量的内容或研究结果的意义。这里讨论的是工具开发过程的最后阶段；计算和分析结构效度与内部一致性信度。给出了一个将信度和效度方法应用于一个假设工具的示例。
