Sexual assault in the US military: A comparison of risk in deployed and non-deployed locations among Operation Enduring Freedom/Operation Iraqi Freedom active component and Reserve/National Guard servicewomen.

BACKGROUND: To determine whether sexual assault in the military (SAIM) among active component and Reserve/National Guard servicewomen is more likely to occur in deployed or non-deployed locations; and which location poses greater risk for SAIM when time spent in-location is considered.

METHODS: A total of 1337 Operation Enduring Freedom/Operation Iraqi Freedom era servicewomen completed telephone interviews eliciting socio-demographics, military and sexual assault histories, including attempted and completed sexual assault.

RESULTS: Half of the sample had been deployed (58%). Overall 16% (N = 245) experienced SAIM; a higher proportion while not deployed (15%; n = 208) than while deployed (4%; n = 52). However, the incidence of SAIM per 100 person-years was higher in deployed than in non-deployed locations: 3.5 vs 2.4. Active component and Reserve/National Guard had similar deployment lengths, but Reserve/National Guard had higher SAIM incidence rates/100 person-years (2.8 vs 4.0).

CONCLUSIONS: A higher proportion of servicewomen experienced SAIM while not deployed; however, adjusting for time in each location, servicewomen were at greater risk during deployment.
