Background/Description
The Life Events Checklist for DSM-5 (LEC-5) – Interview Version is a structured interview tool designed to assess exposure to potentially traumatic events. This checklist, like other LEC-5 formats, aligns with DSM-5 trauma definitions and is used by clinicians to help identify events that may contribute to the development of post-traumatic stress disorder (PTSD) and related conditions. While the standard version is self-administered, the Interview Version offers more depth by facilitating a conversational approach, allowing clinicians to clarify and explore responses in real-time.
Developed for use in clinical and research settings, the interview format enables a more nuanced understanding of an individual’s trauma history, promoting accurate assessment of exposure types and the individual’s subjective experiences.

- Consists of Multiple items, covering types of traumatic events (e.g., natural disasters, combat, violence).
- The clinician guides the respondent through each item, asking clarifying questions when needed to determine the level of exposure.
Reliability and Validity
The LEC-5 Interview Version has been validated in numerous studies and is known for its reliability in capturing traumatic experiences relevant to PTSD and other trauma-related conditions. This version’s interactive nature increases the accuracy of reported events, often leading to a more comprehensive trauma history.
