Reliability assessments are appropriate for each research instrument in a study. Measures of internal consistency are a popular set of assessments with Cronbach's alpha being the most favored. Two other measures of internal consistency, theta and omega, have particular characteristics that make their use desirable under certain circumstances. Each of these three measures and its computation is described and examples provided.
可靠性评估适用于研究中的每一种研究工具。内部一致性测量是一组常用的评估方法，其中Cronbach's alpha最为常用。另外两种内部一致性测量方法，theta和omega，具有特定的特征，使得它们在某些情况下的使用是可取的。本文描述了这三种测量方法及其计算方式，并提供了示例。
