Health SMART (Stress Management and Relaxation Training) to Improve Vaccine Immune Response
The proposed investigation will conduct a randomized, clinical trial to test the efficacy of a cognitive behavioral stress management (CBSM) group intervention on immune response to vaccine and distress among women at elevated risk for breast cancer.
Hypothesis 1: Women who participate in the CBSM intervention will have a larger primary and secondary antibody response to vaccines compared to women in the comparison group.
Hypothesis 2: Women who participate in a 10-week CBSM group intervention will report lower levels of distress immediately after and 6 months after the intervention compared to women in the comparison group.

|Study Design:||Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
|Official Title:||Can Stress Management Improve Vaccine Immune Response|
- Independent sample t-test will be used to compare 1) antibody change scores from before to after the first and second dose of vaccine, and 2) distress change scores from before to after the intervention [ Time Frame: length of protocol ]
- Multiple regression analyzes will be used to test changes in cortisol and changes in perceived risk of breast cancer; coping or social support mediate the effects of the intervention on antibody response to vaccine and distress [ Time Frame: length of protocol ]

Behavioral: Cognitive Behavioral Stress Management (CBSM) group intervention
Chronic stress can impair immune function, including immune response to vaccines. This has important implications for cancer control and prevention because tumor vaccines are emerging as tools for cancer treatment and prevention, and the cohort that would benefit from the vaccines is likely to be stressed. Women at elevated risk for breast cancer experience significant levels of distress that have been associated with immune function decrements. Interventions to treat distress-related immune decrements among these women are needed because these women will be among the first candidates for breast cancer vaccines. In theory, stress-management interventions should improve immune function and response to vaccines, but the findings to date are mixed, in part because most intervention studies have been done with medical patients who by nature have immune confounds. Thus, it is unknown how stress management interventions affect immune function in stressed but otherwise healthy people, such as women at elevated risk for breast cancer.
Comparison: Women will be randomly assigned to a 10-week structured, CBSM intervention or a wait-list comparison group with delay participation in the intervention. The comparison group will be offered the full CBSM intervention after all assessment time points have been completed.
