Usually providers of mental-health care help make the diagnosis of paraphilias, including licensed mental-health therapists, psychiatrists, psychologists, psychiatric nurses, and social workers. One of these professionals will likely conduct or refer the person with paraphilia for an extensive medical interview and physical examination as part of establishing the diagnosis. To ensure that the paraphilic individual does not suffer from a medical condition that could complicate the assessment or treatment of their mental-health condition, routine laboratory tests are often performed during the initial evaluation.As part of this examination, the sufferer may be asked a series of questions from a standardized questionnaire or self-test to help assess the presence of paraphilic symptoms. Thorough exploration for any history or presence of all mental-health symptoms will be conducted such that paraphilia can be distinguished from other types of mental disorders. People with pedophilia may also suffer from a personality disorder or mood disorder, and about 60% have an additional paraphilia, like exhibitionism, voyeurism, or sadism.In order to qualify for the diagnosis of a paraphilia, the individual has to experience recurrent, significant sexual arousal by the object of their attraction; act on that attraction in urges, fantasies, or actions; and experience the symptoms for at least six months to the point that the individual suffers significant levels of distress or interference with his or her work, social function, or other important aspects of life.
