Domestic Violence (DV) or Intimate Partner Violence (IPV) includes actual or threatened physical or sexual violence, or psychological and emotional abuse, directed toward a spouse, ex-spouse, current or former boyfriend or girlfriend, or current or former dating partner. DV is a widespread problem that occurs among all ages, genders, races, educational backgrounds, cultures, religions, sexual orientations, and socioeconomic groups. It is the single largest cause of injury to women between the ages of 15 and 44 in the United States, more common than muggings, car accidents, and rapes combined. This presentation will discuss the scope, causes, effects, and effective responses to DV, including what school mental health professionals can do support students affected by this damaging behavior.
