Self-report surveys are a common method of collecting data on protective equipment use in sport. The aim of this study was to assess the validity of self-reported use of appropriate protective eyewear by squash players. Surveys of squash players' appropriate protective eyewear behaviours were conducted over two consecutive years (2002 and 2003) at randomly-selected squash venues in Melbourne, Australia. Over the two years, 1219 adult players were surveyed (response rate of 92%). Trained observers also recorded the actual on-court appropriate protective eyewear behaviours of all players during the survey sessions. Eyewear use rates calculated from both data sources were compared. The self-reported appropriate protective eyewear use rate (9.4%; 95% CI 7.8, 11.0) was significantly higher (1.6 times more) than the observed rate (5.9%; 95%CI 4.6, 7.2). This suggests that players may over-report their use of appropriate protective equipment, though some may have incorrectly classified their eyewear as being appropriate or suitably protective. Studies that rely only on self-report data on protective equipment use need to take into account that this could lead to biased estimates.
自我报告调查是收集体育活动中防护装备使用数据的常用方法。本研究的目的是评估壁球运动员自我报告的适当防护眼镜使用情况的有效性。在澳大利亚墨尔本随机选择的壁球场地，连续两年（2002年和2003年）对壁球运动员的适当防护眼镜使用行为进行了调查。在这两年中，共调查了1219名成年运动员（回复率为92%）。训练有素的观察员还记录了调查期间所有运动员在球场上实际的适当防护眼镜使用行为。对从这两个数据源计算出的眼镜使用率进行了比较。自我报告的适当防护眼镜使用率（9.4%；95%置信区间7.8，11.0）显著高于观察到的使用率（5.9%；95%置信区间4.6，7.2）（高出1.6倍）。这表明运动员可能高估了他们对适当防护装备的使用，尽管有些人可能将他们的眼镜错误地归类为适当或具有足够防护性的。仅依赖防护装备使用自我报告数据的研究需要考虑到这可能导致有偏差的估计。
