The grid test for schizophrenic thought disorder was administered to a sample of 149 psychiatric patients. This sample was drawn from a population with a known base rate of schizophrenia and an estimated base rate of thought disorder, thus allowing for the calculation of population specific cutting scores for the grid test. The grid test, using these data along with others from previous grid test studies, was then analysed for diagnostic efficiency using conditional probability formulae. The conclusion reached is that the grid test for schizophrenic thought disorder is unsatisfactory as a diagnostic instrument.
对149名精神科患者进行了精神分裂症思维障碍的网格测试。该样本取自一个已知精神分裂症基础率和估计思维障碍基础率的人群，从而能够计算出该网格测试针对该人群的特定临界分数。然后，利用这些数据以及先前网格测试研究中的其他数据，运用条件概率公式对网格测试的诊断效率进行了分析。得出的结论是，作为一种诊断工具，精神分裂症思维障碍的网格测试并不令人满意。
