Of 106 patients attending a gender-identity clinic, 73% satisfied DSM-III criteria for transsexualism. These DSM-III positives had a significantly younger age of onset and were less likely to experience sexual arousal with cross-dressing than those who did not satisfy DSM-III criteria. They were also significantly more likely to fulfil a definition of 'core transsexualism'. 'Core transsexualism' may represent a subgroup within DSM-III criteria for transsexualism and its defining features in this study were an early age of onset, low sexual activity, lack of sexual arousal with cross-dressing and homosexual orientation. Of the whole sample, 23% were referred for gender reassignment surgery, of whom 100% were DSM-III positive and 60% were 'core transsexuals'.
在前往一家性别认同诊所就诊的106名患者中，73%符合《精神疾病诊断与统计手册》第三版（DSM-III）中关于易性癖的标准。这些符合DSM-III标准的患者发病年龄显著更小，与不符合DSM-III标准的患者相比，他们通过穿着异性服装获得性唤起的可能性更低。他们也更有可能符合“核心易性癖”的定义。“核心易性癖”可能代表了DSM-III易性癖标准中的一个亚组，其在本研究中的定义特征为发病年龄早、性活动少、穿着异性服装时缺乏性唤起以及同性恋取向。在整个样本中，23%的患者被转诊进行性别重置手术，其中100%符合DSM-III标准，60%为“核心易性癖者”。
