In Study 1, Japanese-version CERQ was developed and examined its reliability and validity. In Study 2, first, it was revealed that all strategies except positive refocusing were significantly different in the use tendency. Under the low negative emotion condition, positive reappraisal, put into perspective, self-blame, and refocus on planning were frequently used. And then, multiple regression analysis showed that under the low negative emotion condition, positive reappraisal predicted lower anxiety and depression, but catastrophizing predicted higher anxiety and depression. In contrast, under the high negative emotion condition, rumination and catastrophizing predicted higher anxiety, and self-blame predicted higher depression.
