Optimism is important in enhancing human psychological and physical well-being; however, the association of optimism with burnout has received little attention in sport psychology. This study recruited 139 young volleyball players (M = 16.3 yr., SD = 0.8) to examine this relation. Athletes completed the Chinese version of the Life Orientation Test at Time 1 and 4 mo. later (Time 2). The Chinese version of the Athlete Burnout Questionnaire was also administered. Analysis showed scores on optimism were negatively related to athletes' burnout scores.
