Jane,
The recent ACE 'study' of english speaking Nigerian prisoners (298 spoke/read and/or understood english, and participated in the study), also cross-checked the validity of another trauma screening tool, and may have also explored 'resilience' as well--I don't recall for certain about the resilience part. It basically validated both trauma screening tools, though.
Thank You for posting the link to the Resilience Score, for Vistoria, too!
