This study examined characteristics of sexual assaults among a communi
ty-based sample of 1,162 women that were committed by unknown and know
n assailants Assailant groups were examined on a continuum of familiar
ity that included strangers (30.6%), acquaintances known for less than
24 hours (13.9%), acquaintances known for more than 24 hours (40.2%),
and current or previous husbands or boyfriends (15.3%). Client backgr
ound, presentation information, and assault characteristics were exami
ned through client self-report as well as clinician observation. The r
esults of the study support the association of some assault characteri
stics and assailant-victim relationship status. In particular variable
s related to coercion, violence, and physical trauma revealed that ass
aults by husbands or boyfriends were more violent and resulted in more
physical trauma to victims than assaults by other known assailants. O
verall, the results indicated that husband/boyfriend assaults were mos
t similar to those committed by strangers.
