The Rorschach protocols of 43 males consecutively admitted to a university outpatient clinic were scored for frequency of the 20 Wheeler signs of homosexuality. Based on case history data, patients were assigned to homosexual, sex-role disturbed, or normal-control groups. In addition to the traditional group comparison the results were analyzed to yield P (Ci/Rj); that is, the probability of criterion group membership given test indicator. Both the homosexual and sex-role disturbed group displayed significantly more Wheeler signs than normals. Furthermore, given a Wheeler sign score of 15%, .75 of the predicted-homosexual group would be correctly classified compared to a .21 baserate prediction. It was suggested that expressing results as P (Ci/Rj) provides information more relevant to the clinician than is provided by the traditional practice of reporting significant differences between groups.
对连续入住大学门诊的43名男性的罗夏墨迹测验记录进行评分，统计20种同性恋惠勒体征的出现频率。根据病例史数据，将患者分为同性恋组、性别角色紊乱组或正常对照组。除了传统的组间比较外，还对结果进行分析以得出P（Ci/Rj）；即根据测试指标判断所属标准组别的概率。同性恋组和性别角色紊乱组表现出的惠勒体征均显著多于正常组。此外，若惠勒体征得分为15%，预测同性恋组中有0.75的人能被正确分类，而基于基础概率的预测准确率为0.21。研究表明，与传统的报告组间显著差异的做法相比，以P（Ci/Rj）形式呈现结果能为临床医生提供更相关的信息。
