The role of attachment style in relation to forgiveness was investigated in 2 betrayal interviews. Blood pressure and heart rate were assessed, along with attachment style, forgiveness, empathy, and emotional expressiveness. Securely attached individuals were more forgiving of the specific offense, had higher levels of trait forgiveness, and expressed more positive emotion. Securely attached tadults had lower interview systolic blood pressure and exhibited greater blood pressure recovery. Attachment style may be an independent antecedent of forgiveness. © 2006 by the American Counseling Association. All rights reserved.
