The authors examined the psychometric characteristics and factor structure of the Civilian Version of the PTSD Checklist (PCL‐C; F. W. Weathers, B. T. Litz, J. A. Huska, & T. Keane, 1994) in elderly survivors, aged 66–90, of the 2004 Florida hurricane disasters. Confirmatory factor analyses of nine models of PCL‐C structure revealed the strongest support for a 4‐factor model consisting of reexperiencing, avoidance, numbing, and arousal dimensions. Future studies will be facilitated by the knowledge that the PCL‐C 4‐factor model appears to apply across the adult age range and a variety of posttraumatic stress disorder‐producing conditions.
