What must be specified in a diagnosis of Fetishistic Disorder?

In the diagnosis of Fetishistic Disorder, it is essential to specify if the individual is attracted to nonliving objects or specific body parts. This is a key criterion within the DSM-5, as it distinguishes Fetishistic Disorder from other paraphilic disorders. Focusing on nonliving objects or body parts helps clarify the nature of the fetish, which is central to this diagnosis. The presence of such fetishistic interests can significantly impact the individual's functioning and relationships, hence the need for specificity in identifying the objects of focus.

The other aspects that are specified in the DSM-5 regarding paraphilic disorders may include the nature of the partner or the duration but are not as central to defining Fetishistic Disorder itself as understanding what the fetish entails. Therefore, the correct specification directly relates to the objects or body parts that evoke sexual arousal and satisfaction in the individual, which is why this answer is paramount in the diagnostic process.
