Emotion regulation has been the center of the attention for a few decades, contributing to, for example, the understanding of the relation between emotion and well-being. However, criticisms and reconsiderations of self-report scale, which have played an important role in emotion regulation studies, haven't been thoroughly done. Therefore, on the basis of Gross's process-model, the present paper reviewed the existing scales of “attention deployment,” “cognitive change,” and “response modulation,” which are the three points of the emotion regulation process. In particular, the uniqueness and problems of each scale are referred when necessary. The limitation of the present paper and future view of emotion regulation studies in general are discussed in conclusion.
