Most empirical investigations of rape-related symptomatology have focused on either the relationship between the perpetrator and the victim (i.e., Stranger or Acquaintance), the method used by the perpetrator (Forcible or Incapacitated), or whether or not the victim conceptualizes the experience as "rape" (Acknowledged or Unacknowledged victims). Despite the importance of all three factors, little is known about the interaction between these factors on post-traumatic functioning. The goal of the present study was to assess the joint impact of these factors in order to evaluate their influence on the post-traumatic functioning of a national sample of women with rape experiences (N=789). Of particular interest were victims who knew their assailant, were incapacitated, and did not label the act "rape." It was hypothesized that these women would report significantly higher levels of substance use, stigmatization, and revictimization, and significantly fewer disclosures, than women with more traditional rape experiences. Elevated symptoms of PTSD and depression were expected in the whole sample. Though no three-way interactions were found, Method by Conceptualization interactions suggested that Acknowledged-Incapacitated victims were most at risk for symptoms of PTSD and depression, while Unacknowledged-Incapacitated victims were at risk for alcohol abuse. Consistent main effects were found for Conceptualization in which Unacknowledged victims reported fewer mental health symptoms than Acknowledged victims, supporting past research that suggests that not conceptualizing an assault as "rape" may serve a protective function for victims.
