Common data elements for posttraumatic stress disorder research.

Area of Science:

• Psychiatry
• Clinical Psychology
• Public Health

Background:

• Standardization of measurement is crucial for advancing posttraumatic stress disorder (PTSD) research.
• Previous efforts in standardizing PTSD measurement have been reviewed.
• A U.S. federal interagency expert work group was convened.

Purpose of the Study:

• To identify common data elements for PTSD research.
• To establish standardized measurement approaches for PTSD.
• To provide recommendations for core and supplemental data elements.

Main Methods:

• An expert work group with 7 members was formed.
• The group reviewed existing and contemporary measurement standardization efforts for PTSD.
• Discussions were held to define construct domains and assign measures.
• Eight construct domains relevant to PTSD were identified and defined.

Main Results:

• Eight key construct domains for PTSD research were identified: demographics, trauma exposure, moderators, trauma assessment, screening, symptoms/diagnosis, functioning/disability, and mental health history.
• Measures were categorized into 'core' (low cost, broad applicability) and 'supplemental' (higher cost, stronger psychometrics).
• Recommendations were made for using core and supplemental measures based on study resources.

Conclusions:

• The identified common data elements and categorized measures provide a framework for standardized PTSD research.
• The recommendations aim to improve the quality and comparability of PTSD research findings.
• The voluntary nature of standardization and potential limitations were highlighted.
