Literature reported PTSD rates in combat exposed veterans, although the Italian Navy military personnel has been frequently involved in no-war activities in most recent years, such as Search and Rescue (SAR) activities of civilians involved in catastrophic events. The study aimed at exploring the prevalence of PTSD and its impact on social and work functioning among divers of the Italian Navy employed in the SAR activities for the Costa Concordia shipwreck (2012), the collapsed control tower of the Genoa harbour (2013), and the "Mare Nostrum" and "Triton" immigrant emergency Operations in the Mediterranean Sea.
