Although this strategy is effectiveto reduce negative mood immediately, it has been suggested that distraction foravoidance of one’s negative problems prevent from solving or accepting them (e.g.Steil & Ehlers, 2000). Then, we have examined the effect of “divided-attentiondistraction” which encourage one to recall negative memory intentionally whileengaging in distraction task (Ishikawa & Koshikawa, 2018). In this study, we compared the effect of divided-attentiondistraction on mood and aversion to negative event with distraction aiming atsuppressing thoughts about negative event. Participants were required to engagein divided-attention distraction (group A) or distraction for suppression (groupB) or rest (group C) for 8 minutes, following inducing negative ruminationabout previous negative events. Subsequently, all participants took a rest for5 minutes. Thescore of aversion to the event reduced significantly after distraction andafter 5-minute rest in group A. On the other hand, group B and C did not showsignificant reduction after 5-minute rest. This result suggests that divided-attentiondistraction would promote acceptance or emotion processing.
