The Effects of a Brief Mindfulness Intervention on Emotional Responses and the Moderating Role of Interoception

The Effects of a Brief Mindfulness Intervention on Emotional Responses and the Moderating Role of Interoception

This study examines the effects of a brief mindfulness intervention (body scan) on emotional responses (e.g., affect, heart rate variability (HRV)) compared to an active control group. Another aim is to assess whether the effects of the mindfulness intervention can be augmented by optimizing positive expectations. The moderating role of interception on the mindfulness intervention's effects will also be examined.

This 3-armed study examines the effects of a brief mindfulness intervention (audio-guided body scan) on emotional responses (e.g., affect, and heart rate variability (HRV)) compared to an active control group (listening to an audio-book). Another aim is to assess whether the effects of the mindfulness intervention can be augmented by optimizing positive expectations. The moderating role of interception (i.e., interoceptive accuracy as assessed by the Schandry task) on the mindfulness intervention's effects will also be examined.
