The Life Events Checklist for DSM-5 (LEC-5) is a self-report measure designed to screen for potentially traumatic events in a respondent's lifetime. The LEC-5 assesses exposure to 16 events known to potentially result in PTSD or distress and includes one additional item assessing any other extraordinarily stressful event not captured in the first 16 items.
The LEC was originally developed concurrently with the Clinician-Administered PTSD Scale for DSM-IV (CAPS) to be administered before the CAPS. The LEC demonstrated adequate psychometric properties as a stand-alone assessment of traumatic exposure, particularly when evaluating consistency of events that actually happened to a respondent.
The original LEC also demonstrated convergent validity with measures assessing varying levels of exposure to potentially traumatic events and psychopathology known to relate to traumatic exposure. However, the LEC did not establish that the respondent has experienced an event with sufficient severity to meet DSM-IV criteria for a traumatic exposure (Criterion A1), nor did it assess peritraumatic emotional experiences (Criterion A2).
Changes between the original LEC and LEC-5 are minimal:
Psychometrics are not currently available for the LEC-5. Given the minimal revisions from the original version of the LEC, few psychometric differences are expected.
Three formats of the LEC-5 are available:
For each item, the respondent checks:
Event: Natural disaster (for example, flood, hurricane, tornado, earthquake)
