Mindfulness is an individual practice, where one has a heightened awareness of the present moment. An extensive research literature finds links between trait mindfulness and individual-level physical and mental health benefits. A limited but growing amount of research focuses on the association between mindfulness and romantic relationship satisfaction. Though there have been comprehensive reviews, no study has statistically tested the magnitude of the association between mindfulness and relationship satisfaction. Better understanding the value of this practice for relationships can serve to inform community educators and practitioners focused on promoting healthy family relationships. This study used a meta-analytic technique focused on 12 effect sizes from 10 different studies, and found that the relationship between mindfulness and relationship satisfaction was statistically significant with an overall effect size of .27. This finding suggests that higher levels of mindfulness are associated with higher levels of relationship satisfaction; therefore, educators can reasonably consider level of mindfulness as an education target.
