Studies have shown meditation to be effective (Gayner, Esplen et al. 2011) (Szanton, Wenzel et al. 2011). The thought behind it is that you are taking your mind off of the past and future by concentrating on your breath. Even though problems will still exist you have given your mind a break from being the fight, flight, or freeze mode. (Goldin & Gross 2010)
An 8-week Mindfulness-Based Stress Reduction study (Shapiro, Schwartz, Bonner et al. 1998) on Medical and Premedical Students at the University of Arizona. The study had a high completion rate of 97% which was consistent with previous studies. The data indicate that participation in a mindfulness-based stress reduction intervention can effectively
1) Reduce self-reports of overall psychological distress including depression
2) Reduce self-reported state and trait anxiety
3) Increase scores on overall empathy levels
4) Increase scores on a measure of spiritual experiences assessed at termination of the intervention
These results replicated in the wait-list control group, held across experimenters were observed during the exam period. Further, analysis demonstrated that one’s compliance with treatment played an important role in the outcome.
