The paraphilias: a multiplicity of deviant behaviours

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.
