简要总结
The present study will investigate the effects of a mindfulness training on emotion regulation and social cognition, using several psychological, behavioral, psychophysiological and neuroimaging methods.
详细描述
The aim of the present study is to evaluate the impact of a mindfulness intervention, particularly the mindfulness-based stress reduction (MBSR), on the capacities of emotion regulation and social cognition, in caring/helping professions which are vulnerable to stress. In the context of a longitudinal intervention study, a randomized controlled trial, the efficacy of the MBSR to increase the capacity for self-emotion regulation, empathic attunement, and compassion capacities will be measured. For doing this, several psychological, behavioral, psychophysiological and neuroimaging brain measurements will be used.

时间窗: first acquisition period during 3 weeks before the intervention, second acquisition period during 3 weeks after the intervention.
次要结局
