“内部一致性”常见的英文表达是 "internal consistency"。
例如在心理学、教育学等领域测量工具的信度分析,或者系统、理论、观点等逻辑层面的考察中,都会用到这一表述:
The internal consistency of this psychological scale was assessed using Cronbach's alpha. (使用克朗巴赫α系数评估了该心理量表的内部一致性。)
The theory lacks internal consistency as some of its premises contradict each other. (该理论缺乏内部一致性,因为其部分前提相互矛盾。 )
