研究概览
简要总结
The overarching goal of the proposed research is to investigate the role of emotions in facilitating successful lifestyle change, defined as healthy behavioral decisions repeated daily, or near daily.
Participants are asked to make two lab visits during the course of four weeks to complete electronic questionnaires, be monitored for psychophysiological activity (e.g. heart rate, blood pressure, respiration), and listen to a guided meditation audio track. Additionally, between the two visits participants will be asked to complete weekly surveys that ask about daily meditation practice (outside of the lab) and general emotions.

结局指标
主要结局
Change in positive emotions (as measured by the Modified Daily Emotions Scale)
时间窗: Baseline and Weeks 1, 2, and 3
Modified Daily Emotions Scale (mDES) - This measure of explicit positive affect has been successfully used by the PI in multiple studies to detect changes in positive emotion. Previous work by the PI found that Cronbach's alpha coefficient for the mDES positive emotion composite variable was 0.93 in sample of mid-life community adults similar to those anticipated for this study.
Change in nonconscious incentive salience (as measured by the Affect Misattribution Procedure)
时间窗: Baseline and Weeks 1, 2, and 3
Affect Misattribution Procedure (AMP) - This measure of nonconscious incentive salience has acceptable internal consistency for an indirect measure of affect (.69 - .90) and has been found to predict judgments and behavioral outcomes above and beyond self-report measures.
Changes in meditation time
时间窗: Weeks 1, 2, and 3
Self-reported meditation time recorded daily and weekly. In addition, meditation track play times will be recorded from the iPod.
次要结局
- Cardiac Vagal Tone(Baseline)
