hypothesis for Japanese university students, and its mechanism in relation to
negative life event aversion. Although </span><span>the

Japan</span><span><span>, empirical studies on the
subject are scarce. Further, there are few studies, internationally, on its
mechanism. A questionnaire survey was conducted with university students (</span><i><span>n </span></i><span>=

life event aversion. </span><span>Compared to the
