Earlier this year, along with colleagues Marieke Wichers, Nicole Geschwind, and Frenk Peeters (Maastrict University and University of Groningen), I published a paper on the effects of mindfulness training on the dynamic change trajectories of positive emotions and thoughts over time. This study analyzed data from a randomized controlled study of 110 individuals with histories of depression who were randomly assigned to receive an 8-week Mindfulness-Based Cognitive Therapy intervention or a control condition. Study participants rated their experiences of positive emotions and thoughts on a daily basis using a method called “experience sampling” (also known as ecological momentary assessment, or EMA), in which they were prompted at random times throughout the day to describe their mental state in the midst of everyday life activities. To analyze this data, we employed a sophisticated statistical technique called multivariate autoregressive latent trajectory modeling (see the Figure above). We found that mindfulness training significantly enhanced positive emotions and positive thoughts from moment-to-moment. Importantly, we also found evidence that mindfulness training may stimulate an upward spiral of positivity, such that increasing experiences of positive emotions on one day stimulated positive emotions and thoughts on the following day, and so forth. In other words, it appears as mindfulness training can enhance positive emotion-cognition interactions that may be important to psychological flourishing (and physical health). These data provide support for my new Mindfulness-to-Meaning Theory (see the Figure above), which will be featured on this website in a month or two when my paper about this theory will be published as the target article of the December issue of the esteemed international journal Psychological Inquiry and receive commentary by some of the leading contemplative scientists in the world. Stay tuned!
