Abstract
This paper summarizes the topic of well-being as it applies to competitive athletes, with a particular focus on definitional and conceptual issues. Established definitions within research on human happiness and flourishing based on the hedonic and eudaimonic perspectives are contrasted against definitions applied within sport psychology. The majority of the reviewed sport psychology studies either failed to define well-being or used a variety of labels to describe the construct (e.g., subjective well-being, psychological well-being, mental well-being). A large number of assessments have been used to assess well-being among athletes, but most were applied with only a weak theoretical rationale and did not distinguish between well-being at the global and sport levels. It is concluded that well-being studies within sport psychology have been hampered by conceptual ambiguity, which makes it difficult to compare results across studies and generalize findings in order to develop a sound theoretical base of knowledge. Future research needs to more explicitly define the conceptual framework of well-being and the level (global or context-specific) on which the construct is investigated. Toward this goal, an integrated model is presented to provide a conceptual well-being structure in sport studies, and future directions for research are discussed.
