Abstract
The purpose of present study is to make Japanese version of the Repetitive Thinking Questionnaire (RTQ; McEvoy et al., 2010), which measures repetitive negative thinking (RNT). RNT is defined as attentive, perseverative, frequent, and relatively uncontrolled cognitive activity that is focused on negative aspects of the self and the world (Ehring & Watkins, 2008; Segerstorm et al., 2003). RNT such as worry, rumination, and post-event processing is seen as trans-diagnostic or trans-emotional phenomenon because it correlates with depression, anxiety, and various negative emotions. 107 undergraduate students completed Japanese version of RTQ and other self-report questionnaires. Exploratory factor analysis yielded one factor structure. RTQ and the short version of RTQ demonstrated high internal reliability and were associated with trait worry, negative mood, and non-adaptive metacognition for problem solving. These results suggest that Japanese version of RTQ and the short version have good psychometric properties.
