This differential vulnerability points to specific protective factors that promote coping. The current study investigated the role of fortitude as a potential protective factor among lay trauma counselors in South Africa. Fortitude is derived from positive cognitive appraisals of the self, the family, and external sources of support.

More positive support-appraisals and family appraisals significantly predicted STS (support:
