The purpose of this review was to systematically identify and evaluate the psychosocial interventions used to manage a component of the stress process in competitive sport performers. Inclusion criteria were devised to select research relevant to the topic area. Studies were assessed for inclusion by examination of their title, abstract, and then full text. On the basis of the outcome of this process, 64 studies were included in the review. These studies encompassed a variety of cognitive (n = 11), multimodal (n = 44), and alternative interventions (n = 9). The results indicate that, in general, a variety of stress management interventions are associated with athletes' optimized stress experience and enhanced performance. The findings suggest that the effectiveness of stress management is moderated by a number of diverse design features (e.g., treatment adopted, stress component outcome measured). These design features are important to consider when designing interventions for athletes of various sports, ages, and competitive standards.
