Sponsored by the Centers for Disease Control and Prevention (CDC), the third round of NISVS collects valid and reliable information on the magnitude and trends in intimate partner violence, sexual violence, and stalking. The NISVS is a dual-frame national telephone survey of men and women drawn from a list-assisted RDD sample and a cell phone sample stratified by four U.S. Census regions and includes a nonresponse follow-up. In 2016-2017, 12,500 interviews were completed for the base year and 15,000 interviews were completed for the option year. Approximately 12,500 interviews will be conducted each year for option years 2 and 3. The base year (2017) includes a telephone survey of a random sample of 8,500 active-duty personnel (female and male) and 2,300 wives of married male service members.
