       To help children cope with the effects of trauma, RAND researchers in collaboration with the Los Angeles Unified School District (LAUSD) and UCLA developed the Cognitive Behavioral Intervention for Trauma in Schools, or CBITS, an intervention program designed for mental health professionals to deliver in a school setting.

       CBITS is part of a rich body of RAND work in which researchers have developed and implemented evidence-based public health interventions, evaluated their effectiveness, and used the results to refine the interventions and adapt them for other settings. This work began with Project ALERT (youth smoking cessation) in the mid 1990s and continued with projects such as Community Partners in Care (community-based depression treatment) and Healthy Families (depression care for parents dealing with early childhood developmental delays).

       CBITS consists of group and individual sessions that educate students about the effects of trauma, support them in developing a narrative of the trauma, and help students through cognitive therapy and social problem-solving techniques.

       To assess the effectiveness of CBITS, a team of RAND researchers and colleagues from LAUSD and UCLA conducted a randomized, controlled evaluation in school settings. Students were sorted into two groups. The early intervention group received treatment right after the baseline assessment, while the delayed intervention group received treatment after a three-month lag. In one of numerous analyses, the research team studied 126 Los Angeles-area middle school students who had been exposed to trauma and were experiencing clinically significant symptoms of post-traumatic stress or depression. Researchers assessed the effects of the intervention after three and six months.

       Research Questions How did the intervention affect students' post-traumatic stress and depressive symptoms? How did CBITS affect students' school performance? Was the school-based mental health intervention accepted by students, teachers, and parents?

       CBITS significantly reduced symptoms of post-traumatic stress and depression among students exposed to trauma. Students who received CBITS early performed better in reading and math. The program produced consistent results and was well accepted by students, parents, and teachers.

       Because CBITS can be delivered in group settings, it has expanded children's access to mental health care. A single social worker can screen up to 1,500 students per year and deliver care to more than 200 students per year.

       CBITS is now recognized as a recommended practice by national agencies that assess the quality of mental health interventions, including the U.S. Department of Health and Human Services' Substance Abuse and Mental Health Administration and Centers for Disease Control and Prevention, and the U.S. Department of Justice.

       CBITS has been widely implemented in more than a dozen states and adapted for Spanish-speaking populations, low-literacy groups, and children in foster care. It was also disseminated in New Orleans following Hurricane Katrina for work with children exposed to the storm. CBITS has been implemented in Australia, China, Japan, and Guyana.

       A version of CBITS, known as Support for Students Exposed to Trauma (SSET), has been adapted for delivery by regular school staff with no mental health training.

       RAND investigators teamed up with 3-C Institute for Social Development to create a website that provides training and implementation support for mental health professionals to deliver CBITS, free of charge.
