Abstract：
Overuse injuries, which have a high prevalence in sport, are suggested to result in different affective responses in comparison to traumatic injuries. Affects may also reciprocally act as risk factors for overuse injury. The aim of this study was to examine the associations between overuse injury and affects within a longitudinal follow-up design. Competitive athletes (N = 149) of various sports and levels of competition completed the Positive and Negative Affect Schedule (PANAS) and the Oslo Sports Trauma Research Centre Overuse injury questionnaire (OSTRC-O) once a week over 10 consecutive weeks. Bivariate unconditional latent curve model analyses with structured residuals were performed to evaluate the associations within and across weeks between OSTRC-O severity score and affects. Results indicated that OSTRC-O severity score and positive affects (PA) had a statistically significant negative within-week relation (r = -24.51, 95% CI = [-33.9, -15.1], p < 0.001). Higher scores of overuse injury were significantly related to lower levels of PA across weeks (ß = -0.02, 95% CI = [-0.04, -0.001], p = 0.044), while the reciprocal effect of PA on overuse injury was not significant (ß = -0.13, 95% CI = [-0.52, 0.26], p = 0.51). No statistically significant association was observed between OSTRC-O severity score and negative affects, neither within nor across weeks. Our findings suggest that overuse injury may have adverse psychological consequences on the long run through lessened PA and address the need for providing sustainable psychological support focusing upon such PA when working with athletes experiencing overuse injury.
摘要：
过度使用伤害,在体育运动中患病率很高，与外伤相比，建议导致不同的情感反应。影响也可能是过度使用伤害的危险因素。这项研究的目的是在纵向随访设计中检查过度使用伤害与影响之间的关联。各种运动和比赛水平的竞技运动员（N=149）连续10周每周完成一次正面和负面影响时间表（PANAS）和奥斯陆运动创伤研究中心过度使用伤害问卷（OSTRC-O）。进行了具有结构化残差的双变量无条件潜在曲线模型分析，以评估OSTRC-O严重程度评分和影响之间的关联。结果表明，OSTRC-O严重程度评分和积极影响（PA）在一周内具有统计学意义的负相关（r=-24.51，95％CI=[-33.9，-15.1]，p<0.001)。过度使用损伤的较高评分与周中PA的较低水平显著相关(β=-0.02,95%CI=[-0.04,-0.001],p=0.044),而PA对过度使用损伤的相互影响不显著(β=-0.13,95%CI=[-0.52,0.26],p=0.51）。在OSTRC-O严重程度评分和负面影响之间没有观察到统计学上的显着关联，无论是在几周内还是跨周。我们的发现表明，从长远来看，过度使用伤害可能会通过减少PA而产生不利的心理后果，并解决了在与遭受过度使用伤害的运动员一起工作时提供针对此类PA的可持续心理支持的需求。
