Objective: The aim of this study was to examine whether there would he diff
erences in reported versus unreported cases of childhood rape on incident c
haracteristics including life threat, physical injury, identity of the perp
etrator, frequency of assault(s), and rates of posttraumatic stress disorde
r or major depression.
Method: In a telephone interview, a national probability sample of 4,008 (w
eighted) adult women was screened for a history of completed rape in childh
ood. Respondents were also assessed for DSM-III-R diagnoses of major depres
sive episode and/or posttraumatic stress disorder (PTSD). Three hundred for
ty-one (8.5%) of these women were victims of at least one rape prior to the
age of 18, for a total of 437 completed rapes. Of these 437 rape incidents
, 52 (11.9%) were reported to the police or other authorities.
Results: Significant differences were obtained between reported versus nonr
eported cases on incident characteristics, including life threat, physical
injury, identity of the perpetrator. Reported cases were more likely to inv
olve life threat and/or physical injury, and were more likely to have been
committed by a stranger than nonreported cases. No significant differences
between reported and nonreported cases were found concerning whether the ra
pe involved a single incident versus series of events, or rates of PTSD or
major depression.
Conclusions: Findings suggest that different characteristics are associated
with reported versus unreported cases of childhood rape. Since few cases o
f childhood rape are actually reported to the authorities, it appears that
we may be missing valuable information. Implications for research and clini
cal intervention are discussed. (C) 1999 Elsevier Science Ltd.
