Objective: This clinical study was devised to elucidate the behaviors, moti
vations, and psychopathology of stalkers. Method: It concerned 145 stalkers
referred to a forensic psychiatry center for treatment. Results: Most of t
he stalkers were men (79%, N=114), and many were unemployed (39%, N=56); 52
% (N=75) had never had an intimate relationship. Victims included ex-partne
rs (30%, N=44), professional (23%, N=34) or work (11%, N=l6) contacts, and
strangers (14%, N=20). Five types of stalkers were recognized: rejected, in
timacy seeking, incompetent, resentful, and predatory. Delusional disorders
were common (30%, N=43), particularly among intimacy-seeking stalkers, alt
hough those with personality disorders predominated among rejected stalkers
. The duration of stalking was from 4 weeks to 20 years (mean=12 months), l
onger for rejected and intimacy-seeking stalkers. Sixty-three percent of th
e stalkers (N=84) made threats. and 36% (N=52) were assaultive. Threats and
property damage were more frequent with resentful stalkers, but rejected a
nd predatory stalkers committed more assaults. Committing assault was also
predicted by previous convictions, substance-related disorders, and previou
s threats. Conclusions: Stalkers have a range of motivations, from reassert
ing power over a partner who rejected them to the quest for a loving relati
onship. Most stalkers are lonely and socially incompetent, but all have the
capacity to frighten and distress their victims. Bringing stalking to an e
nd requires a mixture of appropriate legal sanctions and therapeutic interv
entions.
