Spoont, M.R., Williams, Jr., J.W., Kehle-Forbes, S., et al. (2015). Does This Patient Have Posttraumatic Stress Disorder? Rational Clinical Examination Systematic Review. Journal of the American Medical Association. 314(5):501-510.
The authors reviewed studies of screening instruments for post-traumatic stress disorder (PTSD) that used gold standard structured clinical diagnostic interviews and had interview samples of at least 50 individuals. They found that two screening instruments, PC-PTSD and the PTSD Checklist, were easy to administer and demonstrated "reasonable performance characteristics for use in primary care clinics or in community settings."
