Examining the validity of test results using specialised methods is still a relatively new venture and many different approaches are taken to the same task. This paper discusses some of the reasons why discrepant results and differing conclusions may be arrived at by clinicians or researchers, depending on their theoretical and practical choices. These choices include whether to test for effort, what methods to use, how to employ effort tests, what failure criteria to apply and how to interpret individual results. Equally important is the decision about whether or not to employ effort testing to remove error from data in group research studies. No concensus has yet been reached on the need for systematic effort testing in group studies but there are indications that it should be a serious consideration because controlling for invalid data can lead to altered conclusions.
使用专业方法检验测试结果的有效性仍是一项相对较新的工作，针对同一任务有许多不同的方法。本文讨论了临床医生或研究人员可能得出不一致结果和不同结论的一些原因，这取决于他们的理论和实际选择。这些选择包括是否进行努力程度测试、使用何种方法、如何应用努力程度测试、采用何种失败标准以及如何解释个体结果。同样重要的是，在群体研究中决定是否采用努力程度测试以去除数据中的误差。对于群体研究中是否需要进行系统的努力程度测试尚未达成共识，但有迹象表明这应是一个严肃的考虑因素，因为控制无效数据可能会导致结论改变。
