Acceptance lowers stress reactivity: Dismantling mindfulness training in a randomized controlled trial

Objective: Mindfulness interventions, which train practitioners to monitor their present-moment experience with a lens of acceptance, are known to buffer stress reactivity. Little is known about the active mechanisms driving these effects. We theorize that acceptance is a critical emotion regulation mechanism underlying mindfulness stress reduction effects. Method: In this three-arm parallel trial, mindfulness components were dismantled into three structurally equivalent 15-lesson smartphone-based interventions: (1) training in both monitoring and acceptance (Monitor+Accept), (2) training in monitoring only (Monitor Only), or (3) active control training (Coping control). 153 stressed adults (mean age = 32 years; 67% female; 53% white, 21.5% black, 21.5% Asian, 4% other race) were randomly assigned to complete one of three interventions. After the intervention, cortisol, blood pressure, and subjective stress reactivity were assessed using a modified Trier Social Stress Test. Results: As predicted, Monitor+Accept training reduced cortisol and systolic blood pressure reactivity compared to Monitor Only and control trainings. Participants in all three conditions reported moderate levels of subjective stress. Conclusions: This study provides the first experimental evidence that brief smartphone mindfulness training can impact stress biology, and that acceptance training drives these effects. We discuss implications for basic and applied research in contemplative science, emotion regulation, stress and coping, health, and clinical interventions

Facilitating Meditation with Focused Ultrasound Neuromodulation: A First Investigation in Experienced Practitioners

This study aims to assess the validity of focused ultrasound (FUS) stimulation as a method for facilitating meditative development, which may have application for novice or intermediate meditators seeking to improve their practice. A growing body of work suggests profound benefits to health and wellbeing following consistent meditation practice; however, successfully maintaining such a practice proves to be difficult for many who attempt it. By leveraging what is known about the neural correlates of meditation, we investigate the possibility of lowering this barrier of entry via direct neuromodulation using FUS. Specifically, we applied ultrasound for 12 minutes to either the posterior cingulate cortex, bilateral caudate, or bilateral insula in experienced (vipassana) meditators while they engaged in their habitual mindfulness meditation across four separate one-hour sessions. Subjective effects reported during and after each meditation session involving stimulation are compared to a sham stimulation session, with significant differences considered evidence for an effect of FUS. Physiological effects are also reported. Our preliminary data (n=10) suggests a strong, significant improvement in self-reported meditative depth during/after Caudate stimulation while questionnaires taken after the meditation further suggest an augmented state of meditation as well as general mood induced by this condition. Compounding this, reduced heart rate and increased heart rate variability (compared to sham) were observed following FUS, again unique to the Caudate stimulation condition, while these measures were found to strongly correlate with reported depth, suggesting a mechanistic relationship between these adaptive changes in physiological arousal and successful meditation induced by targeting this structure

How mindfulness training promotes positive emotions: Dismantling acceptance skills training in two randomized controlled trials

Mindfulness meditation interventions – which train skills in monitoring present-moment experiences with a lens of acceptance – have shown promise for increasing positive emotions. Using a theory-based approach, we hypothesized that learning acceptance skills in mindfulness interventions helps people notice more positive experiences in daily life, and tested whether removing acceptance training from mindfulness interventions would eliminate intervention- related boosts in positive affect. In two randomized controlled trials (RCTs) of stressed community adults, mindfulness skills were dismantled into two structurally equivalent interventions: (1) training in both monitoring and acceptance (Monitor+Accept) and (2) training in monitoring only (Monitor Only) without acceptance training. Study 1 tested 8-week group- based Monitor+Accept and Monitor Only interventions compared to a no treatment control group. Study 2 tested 2-week smartphone-based Monitor+Accept and Monitor Only interventions compared to an active control training. In both studies, end-of-day and momentary positive affect and negative affect were measured in daily life for three days pre- and post- intervention using ambulatory assessments. As predicted, across two RCTs, Monitor+Accept training increased positive affect compared to both Monitor Only and control groups. In Study 1, this effect was observed in end-of-day positive affect. In Study 2, this effect was found in both end-of-day and momentary positive affect outcomes. In contrast, all active interventions in Studies 1 and 2 decreased negative affect. These studies provide the first experimental evidence that developing an orientation of acceptance toward present-moment experiences is a central mechanism of mindfulness interventions for boosting positive emotions in daily life
