The development of a trait measure of ruminative thought

A 9-item questionnaire was designed to measure rumination. This questionnaire measures three distinct facets of rumination: emotionality, motivation, and distraction. Together, these factors measure the extent to which people engage in thoughts regarding their progress toward their goals. In Study 1, an exploratory factor analysis of an initial 28 items was used to reveal the underlying structure of the rumination construct. In Study 2, a confirmatory factor analysis revealed support for the hypothesized factor structure proposed by Study 1. Following the suggestions of PROC CALIS (SAS) for model modification, an acceptable model was found that retained 9 items (3 on each factor). Studies 3 and 4 demonstrate the predictive validity of the rumination inventory. Study 3 provides evidence of a correlation between distraction by ruminative thoughts and low scores on a statistics examination. Study 4 shows a negative correlation between distraction by ruminative thoughts and time taken to learn to solve a geometric puzzle.
