The Defense Department said it made the survey much more explicit and detailed this year in order to get more accurate results as the military struggles to reduce sexual assaults while also encouraging victims to come forward to get help. Early last year, a report on the 2012 anonymous survey results set off a furor when it estimated that 26,000 military members may have been sexually assaulted or subjected to unwanted sexual contact. Exasperated members of Congress complained that the Defense Department wasn't doing enough to combat sexual assault and tried to force changes in the Pentagon's legal and command procedures. The survey begins with questions about sexual harassment, asking about jokes, "sexual gestures or sexual body movements," requests to take or share sexually suggestive pictures or videos or efforts to establish "an unwanted romantic or sexual relationship." [...] she said, Rand received a "relatively small" number of complaints. "If you don't use precise language to describe different types of sexual assault and harassment, people define those terms for themselves in different ways, which leads to ambiguous results," he said. According to the latest report, the number of reported sexual assaults jumped by 50 percent last year as the military worked to get more victims to come forward. Phone numbers and contact information for sexual assault prevention officers are plastered across military bases, including inside the doors of bathroom stalls.
