Letter from the Editor

This issue of RAND Health Quarterly includes nine articles.

In military health, Emily Hoch and others reviewed military service–related traumatic brain injury (TBI) studies to map the progress of TBI research from January 2015 through June 2025 and identify overlaps and gaps in specific areas. A team led by Julia Rollison conducted a mixed-methods study of men and women veterans' access to, knowledge of, and use of contraception and contraceptive care.

In mental health, Graham DiGuiseppi led a research team that evaluated Live Beyond, a California public awareness campaign focused on adverse childhood experiences.
