Results revealed similarities between cases of erotomania and other affectionate/amorous complaints and cases involving persecutory/angry forms of harassing behavior. When major differences were noted between all harassers and the clinic population as a whole in terms of ethnicity, age, educational level, and sex. The analysis concluded that although erotomania exists; other psychiatric disorders can also be diagnosed in individuals accused or harassing and menacing behavior. From the perspectives of the victim and the criminal justice system, the similarities in behavior patterns are more important than the different diagnoses.
