The objective of this research was to assess the extent of nonresponse bias for the estimated rate of unwanted sexual contact (USC rate) in the active duty military. The level of nonresponse bias (NRB) can vary for every question on the survey, but DMDC focused on the USC rate because this is the central question on the survey. Nonresponse bias occurs when survey respondents are systematically different from the nonrespondents. Nonresponse bias can occur with high or low survey response rates, but the decrease in survey response rates in the past decade has resulted in a greater focus on potential NRB. DMDC investigated the presence of nonresponse bias using many different methods, and this paper summarizes various methods and results. 收起
