A randomized controlled trial of Koru: a mindfulness program for college students and other emerging adults.
OBJECTIVE
To evaluate the effectiveness of Koru, a mindfulness training program for college students and other emerging adults.


PARTICIPANTS
Ninety students (66% female, 62% white, 71% graduate students) participated between Fall 2012 and Spring 2013.


METHODS
Randomized controlled trial. It was hypothesized that Koru, compared with a wait-list control group, would reduce perceived stress and sleep problems, and increase mindfulness, self-compassion, and gratitude.


RESULTS
As hypothesized, results showed significant Group (Koru, Wait-List)×Time (Pre, Post) interactions for improvements in perceived stress (F[1, 76.40]=4.50, p=.037, d=.45), sleep problems (F [1, 79.49]=4.71, p=.033, d=.52), mindfulness (F [1, 79.09]=26.80, p<.001, d=95), and self-compassion (F[1, 74.77]=18.08, p<.001, d=.75). All significant effects were replicated in the wait-list group. Significant correlations were observed among changes in perceived stress, sleep problems, mindfulness, and self-compassion.


CONCLUSIONS
Results support the effectiveness of the Koru program for emerging adults in the university setting.
