Use of self-report (questionnaires) is often the most realistic means of screening physical fitness in large participant samples because this method is quicker and cheaper than objective testing. Yet, previous studies have reported equivocal validity to reports of self-perceived fitness. A hybrid self-report variant is the use of self-administered/reported objective measurement. I sought to investigate the relative validity of this variant method compared to self-perception reports. In total 26,452 young Norwegian men and women participated in this study. I collected data during obligatory selection for military conscript service. Approximately half of the participants were asked to rate their endurance level on a five-point Likert scale in an online questionnaire. The other half performed a self-administered 3000 m run and reported the result online. Within 18 months, all participants completed an objective maximal treadmill test at a conscript selection center. I used Spearman correlations () and analyses of variance (ANOVAs) to investigate the relationships between these two self-report methods and the observed objective treadmill performance. Self-perceived and self-tested endurance were both identically correlated with the other-observed treadmill run for men ( = 0.59 < .001) and for women ( = 0.50, < .001); and ANOVAs revealed significant effects of self-perceived and self-tested endurance on treadmill run time, with higher self-reported endurance related to higher treadmill run time. In conclusion, self-perceived and self-tested endurance produced the same correlation coefficients with objectively measured treadmill run time. While there was a moderate relationship between self-reported and objectively measured endurance at the group level, there was substantial individual measurement error that should be considered for individual reports.
使用自我报告（问卷）通常是筛选大量参与者样本身体状况的最现实手段，因为这种方法比客观测试更快、更便宜。然而，先前的研究报告表明，自我感知的健康状况与报告的有效性存在差异。混合自我报告变体是使用自我管理/报告的客观测量。我试图研究这种变体方法与自我感知报告的相对有效性。共有 26452 名挪威年轻男性和女性参与了这项研究。我在强制性兵役选拔期间收集了数据。大约一半的参与者被要求在在线问卷上用五点李克特量表评估他们的耐力水平。另一半人则自行进行 3000 米跑步，并在线报告结果。在 18 个月内，所有参与者都在兵役选拔中心完成了一次客观的最大跑步机测试。我使用斯皮尔曼相关系数 () 和方差分析 (ANOVA) 来研究这两种自我报告方法与观察到的客观跑步机表现之间的关系。男性（ = 0.59 <.001）和女性（ = 0.50， <.001）的自我感知和自我测试耐力与其他观察到的跑步机跑步都具有相同的相关性；方差分析显示自我感知和自我测试耐力对跑步机跑步时间有显著影响，自我报告的耐力越高，跑步机跑步时间就越长。总之，自我感知和自我测试的耐力与客观测量的跑步机跑步时间产生相同的相关系数。虽然在群体水平上自我报告和客观测量的耐力之间存在中度关系，但个体报告时应考虑到个体测量误差。
