This study examines the psychometric properties of the French-Canadian Modified PTSD Symptom Scale (MPSS-FC) in a sample of French-Canadian undergraduates. Findings uncovered a 3-dimensional model for the Frequency and Severity scales, which shared factorial invariance. In addition, the MPSS-FC scales had adequate internal consistency and a satisfactory 5-week test-retest reliability. In view of its satisfactory psychometric properties, the MPSS-FC seems promising as a brief screening measure of PTSD. Indeed, the MPSS-FC as a stand-alone measure could be used with a population known to have been exposed to a traumatic event.
