There are many identified factors that correlate with whether an individual experiences adverse symptoms following a traumatic event. Research indicates that betrayal, where the victim is betrayed by another individual, may be one of these factors. Betrayal Trauma Theory (BTT) posits that betrayal during trauma increases the likelihood of developing adverse psychological symptoms.
