日本語版Experiences Questionnaireの作成と信頼性・妥当性の検討

The Experiences Questionnaire measures decentering, the state of observing thoughts and feelings as temporary events in the mind. This study developed the Japanese version of the Experiences Questionnaire (JEQ). The fit indices in confirmatory factor analysis (n297) suggested an acceptable fit to a model consistent with the original. The correlations (n411) between the J-EQ and the Acceptance and Action Questionnaire-II, the Affective Control Scale, the Ruminative Response Scale, and the Cognitive Control Scale showed adequate construct validity. Internal consistency (n411) and test–retest correlations of factors (n54) indicated good reliability of the J–EQ. The J–EQ can be used to examine the influence of decentering on psychopathology.
