To better define the boundaries of conceptually overlapping constructs of intrapersonal emotion knowledge (EK), we examined meta-analytic correlations among five intrapersonal EK-related constructs (affect labelling, alexithymia, emotional awareness, emotional clarity, emotion differentiation) and attention to emotion. Affect labelling, alexithymia, and emotional clarity were strongly associated, and they were moderately associated with attention to emotion. Alexithymia and emotional awareness were weakly associated, and emotion differentiation was unrelated with emotional clarity. Sample characteristics and measures moderated some of the associations. Publication bias was not found, except for the alexithymia-emotional awareness association. This study helped to clarify the extent to which similarly defined constructs overlap or are distinct, which can inform our decision to adequately label important constructs and employ corresponding measures.

为了更好地定义个人内在情感知识 (EK) 概念上重叠结构的边界，我们检查了五种个人内在 EK 相关结构（情感标签、述情障碍、情感意识、情感清晰度、情感分化）和对情感的关注之间的元分析相关性。情感标签、述情障碍和情绪清晰度密切相关，并且与对情绪的关注中度相关。述情障碍和情绪意识的相关性较弱，情绪分化与情绪清晰度无关。样本特征和测量调节了一些关联。除了述情障碍-情绪意识关联之外，没有发现发表偏倚。这项研究有助于阐明类似定义的结构重叠或不同的程度，
