Current reviews outside of sport indicate that the Life Orientation Test-Revised (LOT-R) items load on two separate factors (optimism and pessimism) and, therefore, should be treated as independent constructs. However, researchers in the sport sciences continue to use the single composite score reflecting a unidimensional definition of optimism. Hence, I sought to explicitly examine the factor structure of the LOT-R with athletes. Results of this study support the two-factor structure, which is consistent with accumulating evidence outside of sport and exercise science. This contribution is an important first step toward continued examination of this instrument and future work on the influence of optimism (versus pessimism) on sport and exercise behavior.
目前,运动领域以外的研究表明,修订后的生活取向测验(LOT-R)项目可分为两个独立的因素(乐观和悲观),因此应被视为独立的结构。然而,运动科学领域的研究人员仍在继续使用反映乐观单维定义的单一综合评分。因此,我试图通过运动员来明确检验 LOT-R 的因子结构。本研究的结果支持双因素结构,这与运动和运动科学领域以外的累积证据一致。这一贡献是对该工具进行进一步检验以及对乐观(与悲观)对运动和锻炼行为影响的未来工作的重要的第一步。
