Reliable and valid measurement of outcomes is a key criterion for assessing the efficacy and effectiveness of nursing interventions. However, measurement in outcomes studies present a special challenge due to the longitudinal nature of such studies as well as the need to operationalize the intervention, specify and select the most relevant contextual and outcome variables, and delineate the influence of other providers on outcomes. This article specifies measurement-related issues and problems that threaten the credibility of outcome studies. Client-related and instrument-related measurement issues which could compromise outcomes measurement are also addressed.
对结果进行可靠且有效的测量是评估护理干预措施有效性和效能的关键标准。然而，结果研究中的测量存在特殊挑战，这是由于此类研究具有纵向性质，以及需要对干预措施进行操作化、明确并选择最相关的背景和结果变量，还要描述其他提供者对结果的影响。本文明确了威胁结果研究可信度的与测量相关的问题和难题。还讨论了可能会损害结果测量的与客户相关和与工具相关的测量问题。
