This study introduces the basic concepts of observational research by defining the terms and discussing some of the critical issues specific to observational research. Observational methods signify a systematic approach to quantifying behavior. A discussion of the major concerns in observational research is presented. These concerns include defining the coding categories; identifying the unit of measurement, the method of recording the observation, and deciding on a sampling strategy; training of observers; and interrater and intrarater reliability.
本研究通过定义术语和讨论观察性研究特有的一些关键问题，介绍了观察性研究的基本概念。观察方法意味着一种量化行为的系统方法。文中对观察性研究中的主要问题进行了讨论。这些问题包括定义编码类别；确定测量单位、记录观察结果的方法以及决定抽样策略；培训观察者；以及评分者间信度和评分者内信度。
