The validity of self-reported diving experience was assessed among 49 U.S. Navy divers. They were asked to provide frequency estimates for the following four diving categories: total dives, dives to more than 31 m, night dives, and dives at surface temperatures of less than 10 degrees C. These estimates were then correlated with official Navy diving records. The resulting correlations ranged from nonsignificant to moderate across the four diving categories. The sample was then divided into three groups according to the extent to which they overestimated diving experience-Low, Medium, and High. The Low group made more total dives and more dives greater than 31 m than either the Medium or High groups. The High and Medium groups did not differ from each other. The groups were similar in overall health status (as indicated but sick call visits) but varied in previous diving accidents. The High and Medium groups incurred substantially more diving accidents per number of total dives made than the Low group. These results indicate that self-reported diving experience information should not be used for purposes in which accuracy is required. Determining discrepancies between estimated and actual experience may also be useful in diver selection and assignment.
在49名美国海军潜水员中评估了自我报告的潜水经历的有效性。他们被要求提供以下四类潜水的频率估计：总潜水次数、深度超过31米的潜水、夜间潜水以及水面温度低于10摄氏度时的潜水。然后将这些估计值与海军官方潜水记录进行关联。在这四类潜水中，所得的相关性从无显著意义到中等程度不等。然后根据潜水经验高估程度将样本分为三组——低、中、高。低高估组的总潜水次数以及深度超过31米的潜水次数均多于中高估组和高高估组。高高估组和中高估组之间没有差异。这些组在总体健康状况方面相似（通过病号就诊情况体现），但在以往潜水事故方面存在差异。高高估组和中高估组每进行的总潜水次数所发生的潜水事故显著多于低高估组。这些结果表明，自我报告的潜水经历信息不应被用于需要准确性的目的。确定估计经验与实际经验之间的差异在潜水员选拔和分配中可能也有用。
