Early life stress (ELS) is associated with a number of psychiatric and medical conditions later in life, thought to be caused by subsequent disruptions in biological processes involved in regulation of stress responses. Given that these alterations have long-lasting effects, there is a great need for effective preventative interventions. The long-term goal of this project is to identify early interventions that may most powerfully mitigate risk for psychiatric illness among adolescents with exposure to early life stress (ELS), with a focus on interventions that can be widely and effectively implemented, have the potential for long-lasting benefits, and can effectively engage targeted neurobiological processes and networks. The specific aims of the present study are to 1) examine how ELS impacts biological processes associated with regulation of stress, and 2) identify how MBI impacts affective symptoms and biological processes dysregulated by ELS. This study supports the efforts to reduce the effects of early adversity in children by testing an impact of an effective psychological intervention on disrupted biological processes caused by early adversity. Successful achievement of the proposed aims will contribute to a) the knowledge base needed to reduce the effects of trauma and stress in children and families and b) the development of easily implemented and disseminated preventative interventions. The proposed study will utilize a multi-method design to examine the effect of mindfulness on biological processes (i.e., stress responses) disrupted by exposure to ELS among adolescents age 13 to 15. Adolescents will first complete self-report measures of childhood adverse experiences, trauma, and neglect. Forty eligible adolescents will be next randomly assigned to either an eight session mindfulness-based stress reduction intervention for teens or no treatment. Pre- and post-intervention assessment will include (a) self-report measures of symptoms and emotion regulation, (b) a blood draw for assessment of inflammatory markers and gene expression, and (c) a stress task with saliva cortisol collected before and after this task.

Cortisol Reactivity
Change in level of cortisol in saliva following a social stress test. Subjects completed the Trier Social Stress Test for Children (TSST-C) at baseline and follow-up. The TSST-C consists of public speaking and serial subtraction components in front of two research confederates. The test takes approximately 20 minutes to complete. Salivary cortisol was collected 20 minutes prior to TSST-C, and 20 minutes following the end of the TSST-C, such that the TSST-C task with data collection spanned approximately one hour.
Time frame: Baseline (pre-intervention); Follow-up (post-intervention) at 6-8 weeks from baseline
Immune System Activity
Change in level of interleukin 6 (IL-6) and C-reactive protein (CRP) in blood
Time frame: Baseline (pre-intervention); Follow-up (post-intervention) at 6-8 weeks from baseline
Mood and Feelings Questionnaire
Measure Description: We used the Mood and Feelings Questionnaire - Short Form (MFQ-sf) to characterize symptoms of anxiety and depression. The MFQ-sf is a 13-item questionnaire with a simple sum score for the entire scale. Minimum score = 0, maximum score = 26. Scores of 8 or more indicate moderate depression. Codings reflect whether the phrase was descriptive of the subject most of the time, sometimes, or not at all. Higher scores indicate greater symptoms of anxiety/depression, while lower scores indicate less anxiety/depression.
Time frame: Baseline (pre-intervention); Follow-up (post-intervention) at 6-8 weeks from baseline
