Post-Survey Change in Affect by Participants’ Military Trauma Exposures and What They were Told about the Survey’s Content. Box plots of participants’ post-survey change in affect according to their military trauma history and what they were told about the survey’s content. Men’s results are shown in the top 4 panels, and women’s, in the bottom 4. Red dots indicate the mean change and black bars, the median change. Positive numbers indicate more sadness or tenseness post survey compared to pre-survey; negative numbers, less sadness or tenseness. No men with a military sexual trauma history were assigned to the cover letter indicating that the survey asked about unwanted sexual attention while in the military.
