One in four dating teens is abused or harassed online or through texts by their partners, according to the largest survey to date on the subject. Social networking sites, texts, cell phones, and e-mails haven’t pushed abuse rates up, but they have given abusers another way to control, degrade, and frighten their partners, even when apart. Digital harassment also warns of a deeper pattern of abuse offline. Victims are 2 times as likely to be physically abused, 2.5 times as likely to be psychologically abused, and 5 times as likely to be sexually coerced.
