Now also remember that every question after question 14 (the one where the traumatic event that supposedly produced trauma is specified) is self-report. In other words it just asks you, “do you have bad dreams? How bad are they on the scale of 0 to 3.”
The answers that the test-taker reports, are added up and the total is compared to a cutoff point. If they add up to enough, bingo, you have post-traumatic stress disorder. And that’s, Jennifer Willmott’s whole point. She’s saying “hey if the score is high enough, you sure qualify for post-traumatic stress.”
