Mind Wandering is the conscious experience when an individual's attention shifts from an ongoing task or external environment to an internal thought stream unrelated to tasks and external stimuli. Mind wandering is closely related to attention and emotion. Frequent mental wandering and negative emotions, especially depression and anxiety, are positively correlated (Smallwood et al., 2009). Mindfulness and mind wandering are essentially a state of consciousness. Trait mind wandering is a general tendency of individuals, representing the overall level of individual mind wandering. Mindfulness training can improve the level of mindfulness, and individuals are more involved in the present; This study hopes to explore whether, at the individual level, the improvement of mindfulness ability can promote peace of mind, reduce the frequency of mental wandering, weaken or cut off the cycle between negative mood and mind wandering, and improve the individual's attention monitoring ability and ability to engage in the present.

Some findings suggest that higher levels of mindfulness are associated with relationship outcomes between partners (Barnes, Brown, Krusemark, Campbell \& Rogge, 2007). This paper aims to explore the impact of mindfulness intervention on intimate relationships in the eastern culture under the intimate relationship interaction model. The selected research objects were: emotionally troubled individuals who were not satisfied with the intimate relationship or marriage relationship, usually one of the parties in the intimate relationship, no matter male or female, no matter sexual orientation; The group received a 49-day Mindfulness Intervention for Emotional Distress (MIED), and the effect of detection.

Increasing evidence has demonstrated the positive effects of mindfulness-based interventions on a range of outcomes, including reducing depression and anxiety on a group level. However, rare research has identified who would most likely benefit from such interventions, especially when online mindfulness-based interventions have been popular, such as MIED in China. No consistent moderator has been found in terms of personal characteristics, including personal traits (de Vibe et al., 2015; Giluk, 2009; Hanley, 2016; Nyklíček \& Irrmischer, 2017). While the level of personality functioning has been proposed by DSM-5 AMPD and ICD-11 as a dimensional criterion crossing normal personality and personality disorders (Bender, Morey \& Skodol, 2011; Tyrer, Mulder, Kim, \& Crawford, 2019), the current study proposes that it could be a moderator of outcomes of MIED. The results could help to explore the potential mechanism underlying the beneficial effects of the MIED theoretically and guide adaptations of MIED practically.

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, at present, the measurement of experiential avoidance is limited to self-reported questionnaires, lacking objective measurement tools. Therefore, this study uses the dichotic listening task to measure experiential avoidance and explore the role of experiential avoidance as the effective mechanism of mindfulness intervention.
