…Until relatively recently, mindfulness was studied in the context of the individual’s own well-being as a stress-reducing psychological mechanism. Researchers now are coming to recognize that some people are better at being mindful, and that those who are have not only less stress but better relationships. According to the theory behind a new study by Auburn University’s Julianne McGill and Francesca Adler-Baeder (2019), it may very well be this ability to focus on the present moment that leads you to set stress aside and be more loving with your partner. Indeed, the authors make the observation that such “positive relationship behaviors are associated with higher relationship quality and in fact, may be one of the most potent predictors of relationship functioning determined by individual studies and meta-analytic procedures” (p. 1).
