Obsessional following is a ''stalking'' behavior in which a person eng
ages in an abnormal or long-term pattern of threat or harassment direc
ted toward a specific individual. In a review of preliminary research
during the past 20 years, the author finds 10 studies, all nonrandom s
amples of convenience, published between 1978 and 1995 in which obsess
ional followers charged with criminal behavior or investigated by law
enforcement (N = 180) were identified. Aggregate data from these studi
es suggest that obsessional followers were likely to be males in their
mid to late thirties with prior psychiatric and criminal histories. T
here was often a chronic history of failed heterosexual relationships
and unemployment, but on average the subjects were more intelligent th
an other criminal offenders. Axis I mental disorders and Axis II perso
nality disorders were common and varied Approximately one-half of obse
ssional followers threatened the victims, but usually were not physica
lly violent. Frequency of any personal violence, depending on the stud
y, was 3-36%. Incidence of homicide was less than 2%. The author theor
izes that obsessional followers, perhaps a subset of stalkers in gener
al, evidence abnormal, ''preoccupied'' attachment patterns their pursu
it fueled by a disturbance in their narcissistic fantasy linking them
to their victims. Such disruption is usually caused by an acute or chr
onic rejection that stimulates rage as a defense against shame.
