Attempting to avoid some of the most common methodological problems involve
d in research on sexual child abuse, we collected data on crimes, perpetrat
ors, and sanctions in all convicted cases of sexual child abuse in a define
d population during a 5-year period. This approach provided amply documente
d and ascertained cases with precise definitions and descriptions of the cr
imes involved, no clinical referral bias, and minimal dependence on memory
effects. The results are valid for the small proportion of cases that lead
to conviction in the context of Swedish legislation. Structured data were c
ollected from the court dossiers in all cases of sexual crimes against mino
rs (less than 15 years of age) tried and sentenced at the courts in the Vas
tra Gotaland region of Sweden between 1993 and 1997. The total number of 49
6 sentences for sexual crimes during the study, period included 203 cases o
f sexual child abuse (40.8%) with 283 victims and 196 perpetrators, all men
. Girls were victims in 85% of the cases, boys in 12%, and boys as well as
girls in 3%. Sexual penetration had occurred in 54.5% of cases and the tota
l proportion of hands-on crimes was 83%. Most perpetrators, 72%, were well
known to the child. The most severe offenses took place within the family.
A wide range of acts were classified as sexual child abuse, but most common
was sexual penetration of a female child by her biological father or a fam
ily friend.
