Three hundred and seventy-five Rorschach protocols were scored blind and then divided into three groups: psychiatric controls, suicide attempts, and suicide effectors. Using the stepwise procedure of multiple discriminant analysis a trio of formulas, composed of six weighted variables each, and a constant, were constructed to apply to each of the three groups based on a test sample of 100 subjects in each group. Cross validation results on a new sample of 25 subjects in each group predicted classification with 52% overall accuracy at step six (chance .33). Internal reliability tests showed all values significant beyond .001. Discussion integrates the test data into the literature on suicide, and attends to the problem of overlap of predictability which occurs with most prediction scales.
对375份罗夏墨迹测验记录进行了盲态评分，然后分为三组：精神科对照、自杀未遂者和自杀成功者。使用多重判别分析的逐步程序，基于每组100名受试者的测试样本，构建了由六个加权变量和一个常数组成的三个公式，分别应用于这三组。在每组25名受试者的新样本上进行交叉验证，结果显示在第六步时总体预测准确率为52%（随机概率为0.33）。内部信度测试表明所有值在0.001水平上显著。讨论将测试数据整合到关于自杀的文献中，并关注大多数预测量表中出现的可预测性重叠问题。
