Does the PTSD checklist catch symptom exaggeration across cultures?

115 contractors were evaluated to test whether a common PTSD measure works outside Western populations.

This study looked at whether a common PTSD questionnaire can reliably spot when someone is exaggerating or faking symptoms—not just in Western countries, but in African populations too. Researchers evaluated 115 contractors from Uganda, Kenya, and Zimbabwe who had worked on U.S. military bases and were being assessed for PTSD in a legal/compensation setting. They compared people who gave credible answers with those who didn’t. While the two groups looked the same in terms of background, the PTSD checklist did a good job telling them apart. The cutoffs that worked best were almost identical to those used in North America. Overall, the results show that this PTSD tool works well across cultures and can be trusted in international forensic evaluations.
