This study investigated whether attitudes toward a complainant of sexual assault are affected by the knowledge that the complainant had previously made a similar allegation. This was a 3 (previous allegation; none, child sexual assault or adult sexual assault) × 2 (whether the previous allegation was substantiated) × 2 (the implied mental health status of the complainant; mental health issue vs. none) multifactorial, experimental study, employing independent-measures and hypothetical vignettes depicting stranger rape scenarios. The dependent variables were victim-blame and believability. The participants were 243 female undergraduate students. A multivariate analyses of variance (MANOVA) revealed several main and interactive effects. Allegations of sexual revictimization were associated with different levels of victim-blame and believability depending on when the previous assault occurred. A history of childhood sexual assault reduced the believability of the complainant and when combined with other factors increased the tendency to attribute victim-blame.
