Background/Description
The Life Events Checklist for DSM-5 (LEC-5) – Standard Version is a self-report screening tool designed to assess exposure to potentially traumatic events that align with DSM-5 trauma criteria. This checklist is widely used in clinical and research contexts to help screen for PTSD-related events or to identify life experiences that may impact mental health. Unlike its Interview Version, the Standard Version is self-administered, providing individuals the flexibility to complete it independently, making it highly accessible for use in various settings.
The LEC-5 Standard Version asks respondents about exposure to a list of 17 potentially traumatic events, such as natural disasters, physical assaults, and life-threatening injuries. Each event can be categorized based on whether it happened directly to the respondent, if they witnessed it, or if it affected someone close to them.
Administration, Scoring and Interpretation
- Suitable for adults and adolescents who may have experienced potentially traumatic events.
- Contains 17 items, each detailing a specific type of event.
- Respondents indicate whether each event has happened to them, was witnessed, affected someone close, or if they are unsure.
Reliability and Validity
The LEC-5 has demonstrated high reliability and is recognized for its utility in accurately identifying trauma exposure across various populations. While it does not diagnose PTSD on its own, it contributes significantly to the comprehensive evaluation of traumatic exposure and potential impact.
