Polyvictimization by dating partners and mental health among U.S. college students.

Studies on mental health effects of partner violence often ignore multiple victimizations or polyvictimization. The current study had several objectives: (a) examine the rate of physical, psychological, and sexual victimization and combinations of them (polyvictimization) among a sample of students at 19 U.S. colleges; (b) examine the association between victimization and depressive symptoms and posttraumatic stress (PTS) symptoms; and (c) examine the relation of polyvictimization to these mental health effects. A substantial number were polyvictims. As predicted, polyvictimization in almost all analyses was the strongest predictor of PTS symptoms for both men and women. Polyvictimization was a significant predictor of depressive symptoms for women. These findings highlight the importance of including polyvictimization in future work on the mental health effects of partner violence.
