The primary purpose of the present study is to investigate the relationship between mindfulness and stress habituation. The investigators propose to measure the effect of mindfulness on stress habituation by randomly assigning participants to a 6-week mindfulness-based stress reduction group intervention, a cognitive-behavioral skills group comparison intervention, or a waitlist control condition followed by repeated acute psychosocial stress testing (2 laboratory sessions on 2 separate days). Saliva will be collected from participants throughout both laboratory testing sessions to measure HPA axis activation (an essential stress-responsive system), along with other measures of physiological and psychological stress (e.g., heart rate, blood pressure, emotions). Mediators and moderators of treatment outcome will be examined. The cognitive-behavioral skills group condition is an appropriate comparison group due to the well-documented efficacy of cognitive-behavioral interventions on stress.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| No intervention wait-list | No Intervention | This arm will receive no intervention for approximately the first 4 months. At the conclusion of the 4-month period, this group will receive a 6-week cognitive-behavioral therapy (CBT) group | |
| Mindfulness Based Stress Reduction(MBSR) | Active Comparator | This arm will receive 6 weekly, 2-hour groups that focuses on mindfulness meditation for stress reduction |
|
| Cognitive Behavioral Therapy (CBT) Group | Active Comparator | This are will receive 6 weekly, 2-hour groups that focus on cognitive-behavioral skills for stress |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Mindfulness Based Stress Reduction | Behavioral | A modified version of traditional MBSR. The current study's version of MBSR is shortened to 6-weeks. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Perceived Stress Scale | A 10-item self-report measure that examines perceived stress. The measure produces one total score. The investigators will measure the change in total score from baseline to the 6-week assessment. | Baseline and 6-weeks after baseline. |
| Salivary cortisol response to repeated acute psychosocial stress | 4 saliva samples will be collected before and after a psychosocial stressor task, which will be administered on two separate occasions separated in time by at least 48 hours. All saliva samples will be assayed for salivary cortisol using enzyme-linked immunoassays. The investigators will measure the change in cortisol stress profiles from the first stressor exposure to the second. | Post-intervention (approximately 7-14 weeks after baseline assessment) |
| Measure | Description | Time Frame |
|---|---|---|
| Cardiovascular response to repeated acute psychosocial stress | Heart rate and blood pressure will be assessed non-invasively and periodically before, during, and after non-invasively a psychosocial stressor task, with an Omron Health Care HEM-907XL Professional Blood Pressure Monitor. The investigators will measure the change in heart rate and blood pressure stress profiles from the first stressor exposure to the second. |
