The study also used measures for resilience, post-traumatic growth (PTG), identity salience, and psychopathology. We conducted two exploratory factor analyses to examine the construct’s structural validity and its independence from similar constructs. The first was on the measure’s items, and the second was on the combined items of WTELS-F, resilience, and PTG. A confirmatory factor analysis was performed on the second sample. Correlation and structural equation modeling (SEM) analysis were conducted to establish discriminant, convergent, and predictive criterion validity. Multigroup invariance was conducted to check the invariance of the measure and SEM model across genders. Results showed that WTELS-F was independent of resilience and PTG and explained a significantly larger variance. The measure and its short version had high internal consistency, test-retest stability, and adequate discriminant, convergent, divergent, and predictive validity. The measure and the SEM model were strictly invariant between genders. Finally, the study’s potential and limitations were briefly discussed. %K Will to Exist Live Survive and Fight %K Resilience %K Identity Salience %K PTG %K Social Support %K Suicidality %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=138242
