RAPE TRAUMA
SYNDROME (RTS)
is thepsychological traumaexperienced by a rape
survivor that includes disruptions to normal physical,
emotional, cognitive, and interpersonal behavior.RTS is
generally broken down into three stages based on the
physical occurrence of the sexual assault.
1.Acute: occurs in the moments, days, and weeks after
sexual assault. victims fall into one of three categories
during this stage:
2
•Expressed: The victim is outwardly upset and
emotional
•Controlled:Rather than outwardly upset, they are in
shock and behaving as if everything is OK
•Shocked Disbelief: The victim is disoriented and may
have a hard time recollecting their attack
2.Outward Adjustment: In this stage, which
can last anywhere from weeks to months, or
even longer, the sexual assault victim does
not appear to be as traumatized and shaken
3.Resolution or Integration:thevictim has come
to terms with the fact that the sexual assault
occurred and does their best to move on from it.
