How Daily Mindfulness Predicts Life Satisfaction: From the Perspective of Mindfulness Coping Model

Previous studies have explored the effect of mindfulness on life satisfaction, but the mechanism has not been explored in terms of daily mindfulness. Therefore, based on the mindfulness coping model, this study uses a daily diary method to examine whether individuals' daily mindfulness could predict life satisfaction and whether this relationship was mediated by rumination. In this study, 178 adults who had not received mindfulness training completed the same diary for continuous 14 days, in which their mindfulness and rumination at state level were measured. Besides, mindfulness, rumination, and life satisfaction at dispositional level were measured before and after the daily reporting process. Hierarchical linear models showed that daily mindfulness is a significant predictor of daily rumination. In addition, both the latent growth curve model and structural equation model showed that the change of daily mindfulness can influence life satisfaction through the change of rumination, and this relationship was also confirmed at the dispositional level. These findings are not only valuable for understanding how mindfulness is linked to rumination and life satisfaction according to the mindfulness coping model, but also contribute to the development of psychological intervention programs aimed at improving individual life satisfaction.
