This study hopes to:
Experiential avoidance refers to individuals resisting experiences or trying to eliminate certain experiences (such as emotions, thoughts, physical feelings, memory and behavioral tendencies, etc.), and trying to adopt corresponding strategies to change these experiences and the situations in which the experiences are generated (Hayes, Wilson, Gifford, Follette, & Strosahl, 1996). Experiential avoidance has been proved to be a maintenance factor for many psychological disorders (Boelen & Reijntjes, 2008), and trying to hide or suppress unpleasant thoughts, feelings and physical feelings will increase the frequency and pain of these same experiences (Gross,1998; Gross,2002; Sloan, 2004; Wegner, 1994). According to some reviews, experiential avoidance is one of the beneficial effects of mindfulness (Brown, Bravo, Roos, & Pearson, 2015; Shapiro et al., 2006). However, no study has examined experiential avoidance as mediator in mindfulness intervention whether in the between-subject or in within-subject level . Therefore, this study uses daily diary research explore the role of experiential avoidance as the effective mechanism of mindfulness intervention.
