The objective of this study was to examine the effectiveness of a pilot mindfulness program for student athletes by assessing mental health, mindfulness ability, and perceived stress before and after the intervention. The mindfulness program was adapted from a program developed at the University of Southern California. The four-session intervention taught the basics of mindfulness, self-care skills, and guided meditations. Participants completed surveys before and after the intervention. Mindfulness ability was assessed with the Cognitive and Affective Mindfulness Scale, mental health was assessed with a modified Short Form Health Survey, and stress was assessed with the Perceived Stress Scale. After the intervention, participants reported improvement in mindfulness ability, t(28) = −2.61, p = .014, mental health, t(28) = −2.87, p = .008, and a trending improvement in perceived stress, t(28) = 1.86, p = .073. A short mindfulness program may be effective for improving mental health and mindfulness ability in collegiate student athletes.
