在定量研究中获得严谨结论的一个基本关键涉及调查工具的选择。心理测量学建议可用于量表开发和测试的过程，以及选择已建立的量表的指导。这些过程是必要的，以解决调查中的现象、经验措施以及最终这些与参与者的世界观之间的理论联系之间的有效性联系。最常见的是提供关于研究设计和方案的详细信息，但很少有详细的理论解释来解释为什么选择特定的工具。当特定的文化、民族或种族群体需要量表时，通常很难找到指导选择的指南。本文详细介绍了在一项正在进行的产后拉美妇女研究中选择工具测量主要过程(干预、调节和调节变量、结果变量)的基本原理[Madres parla Salud]。支撑我们选择的理由包括在适当的时候讨论替代方案。这些样本可能会为正在与特定文化、种族或民族群体合作的其他干预研究人员提供指导，或者为其他寻求选择“最佳”工具的调查人员提供指导。深思熟虑地考虑衡量和阐明我们选择背后的理由，有助于在研究设计中保持严谨，并提高我们评估研究结果的能力。
A fundamental linchpin for obtaining rigorous findings in quantitative research involves the selection of survey instruments. Psychometric recommendations are available for the processes for scale development and testing and guidance for selection of established scales. These processes are necessary to address the validity link between the phenomena under investigation, the empirical measures and, ultimately, the theoretical ties between these and the world views of the participants. Detailed information is most often provided about study design and protocols, but far less frequently is a detailed theoretical explanation provided for why specific instruments are chosen. Guidance to inform choices is often difficult to find when scales are needed for specific cultural, ethnic, or racial groups. This paper details the rationale underlying instrument selection for measurement of the major processes (intervention, mediator and moderator variables, outcome variables) in an ongoing study of postpartum Latinas, Madres para la Salud [Mothers for Health]. The rationale underpinning our choices includes a discussion of alternatives, when appropriate. These exemplars may provide direction for other intervention researchers who are working with specific cultural, racial, or ethnic groups or for other investigators who are seeking to select the ‘best’ instrument. Thoughtful consideration of measurement and articulation of the rationale underlying our choices facilitates the maintenance of rigor within the study design and improves our ability to assess study outcomes.
