The first aim of the present study was to examine whether a mindfulness-based emotion regulation intervention(MBERI) would be effective in increasing experiential acceptance and valued action proposed as its mechanisms of action, based on previous studies and literature review. Its second aim was to examine if increases in the two process variables during the MBERI would predict changes in mental health outcome variables. Fifty three participants in the eight-session MBERI demonstrated significant reductions in depression, anxiety, stress symptoms, and negative affect, as well as increases in subjective happiness, life satisfaction, experiential acceptance, and valued action, at both post-intervention and 1-month follow-up. Increase in experiential acceptance during the MBERI showed significant correlations with changes in all of the mental heath outcome variables from pre- to post-intervention in the expected direction. Increase in valued action during the MBERI showed significant positive relationships with improvements in life satisfaction and subjective happiness and a marginal negative association with reduction in negative affect from pre- to post-intervention. Moreover, increase in experiential acceptance during the MBERI showed significant positive correlations with improvements in life satisfaction and subjective happiness from pre-intervention to follow-up, and increase in valued action during the MBERI showed a marginal negative association with improvements in negative affect from pre-intervention to follow-up. Therefore, these results suggest that the MBERI is efficacious in increasing experiential acceptance and valued action in a Korean sample of university students. The findings also suggest that improvements in mental health outcome variables following the MBERI may be due to increase in experiential acceptance, and that reduction in negative affect may be due to increase in valued action.
