Low reliability when determining criterion a for posttraumatic stress disorder from self-report descriptions of traumatic events: The need for transparent methods.

Findings indicate that relying on self-report from the LEC alone and/or single-rater assessment of open-text trauma descriptions is not recommended for determining whether a traumatic event meets Criterion A. We conclude that it is critical when collecting self-reported PTSD symptoms to provide a clear description of how Criterion A was assessed, initial agreement between raters, and how disagreements were resolved.
