abstract="The Life Events Checklist for DSM-5 (LEC-5) is a comprehensive screening instrument used to detect exposure to a range of potentially traumatic events. Despite its widespread use, research assessing the psychometric properties of scores on the LEC-5-and trauma exposure more broadly-is scarce. Using a large sample of undergraduate students (N = 1,013), we sought to evaluate the reliability of trauma exposure reporting on the LEC-5 across 8- (N = 379) and 12-week (N = 343) intervals. Reliability estimates were examined for trauma exposure type (e.g., experiencing, witnessing), traumatic event type (e.g., sexual assault), and index trauma (i.e., &quot;worst event&quot;) reporting. Reliability was more stable for events that were directly experienced, intraclass correlation coefficients (ICCs) =.62-64, than events that were witnessed, ICCs =.47-.52, or learned about, ICCs =.48-.53. Test-retest agreement was fair to good for reports of sexual assault, physical assault, transportation accidents, natural disasters, and other sexual experiences, κs =.49-.72, but only when individuals directly experienced these events. By contrast, across both assessment intervals, the agreement was attenuated, all κs <.40, for events that individuals witnessed or learned about regardless of event type. For index events, only sexual assault and sudden accidental or violent deaths were consistently reported with a fair or better agreement, κs =.42-.64. These findings suggest that reliable trauma reporting varies largely based on the nature of the traumatic event, yielding important implications for the assessment of DSM-5 Criterion A and posttraumatic stress disorder.<p /> <p>Language: en</p>",
