The DSM-II and DSM-III both allow for multiple diagnoses. The DSM-III acknowledges that a patient may have multiple paraphilias but the true nature and extent of the multiplicity has only been documented recently. In order to study the degree of crossover between the various paraphiliac acts, a study of men who admitted to at least one paraphilia was conducted. A proportional index of multiple deviation was obtained. In addition, the mean number of admitted sexually deviant incidents per paraphilic category was computed as an estimate of the extent of deviant acts committed by this population. The results indicated that paraphiliacs tend to have multiple types of sexual aberrations as well as a high frequency of deviant acts per individual.
《精神疾病诊断与统计手册》第二版和第三版都允许进行多种诊断。《精神疾病诊断与统计手册》第三版承认患者可能有多种性偏好障碍，但这种多重性的真实性质和程度直到最近才得到记录。为了研究各种性偏好障碍行为之间的交叉程度，对承认至少有一种性偏好障碍的男性进行了一项研究。获得了多重偏差的比例指数。此外，计算了每个性偏好障碍类别中承认的性变态事件的平均数量，以估计该人群实施的变态行为的程度。结果表明，性偏好障碍者往往有多种类型的性变态，而且每个人的变态行为频率都很高。
