Development of Japanese Versions of the Mind Wandering: Deliberate and Mind Wandering: Spontaneous Scales

Abstract

Many studies have been done recently on the topic of mind wandering. The importance of distinguishing between intentional mind wandering and unintentional mind wandering has been emphasized. In the present study, Japanese versions of the Mind Wandering: Deliberate (MW-D) and the Mind Wandering: Spontaneous (MW-S) scales (Carriere et al., 2013 ) were developed, and the reliability and validity of the scales were examined. Undergraduates ( N ＝ 357 ) completed the questionnaire. Analysis of the scores confirmed a 2 -factor structure similar to the original English version. Moreover, the reliability and validity of the scales were confirmed using both questionnaire and experimental data from 60 participants. The present study demonstrated that the Japanese versions of the Mind Wandering: Deliberate and the Mind Wandering: Spontaneous scales had acceptable reliability and validity.
