Brief Summary

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.

Detailed Description

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.

Study Groups

Audio-guided mindfulness-based intervention (body scan)

Group Type: EXPERIMENTAL

Body Scan

Intervention Type: BEHAVIORAL

The body scan intervention aims to raise one's awareness of one's own body. It is considered a relaxation, meditation or mindfulness intervention. During the body scan participants will walk through his or her body by focusing their mind on specific body parts without analyzing, judging or reacting.

Enhanced Audio-guided mindfulness-based intervention (body scan)

Participants undergo the same audio-guided body scan intervention. However, in this arm the instruction focuses on the positive effects of mindfulness-based interventions and body scan aiming to optimize participants' interventions outcome expectations of the intervention. The idea of this arm is to assess whether the effects of the mindfulness-based intervention can be augmented by boosting participants positive expectations prior to the intervention.

Group Type: EXPERIMENTAL

Body Scan

Intervention Type: BEHAVIORAL

The body scan intervention aims to raise one's awareness of one's own body. It is considered a relaxation, meditation or mindfulness intervention. During the body scan participants will walk through his or her body by focusing their mind on specific body parts without analyzing, judging or reacting.

Audio-Book

Participants in this group listen to an audio-book for the same duration as the participants in the two experimental groups.

Group Type: ACTIVE_COMPARATOR

Audio-book

Intervention Type: OTHER

Participants listen to an audio book for the same amount of time as the body scan groups
