Overview
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.

Outcomes
Primary Outcomes
Change in affect
Time Frame: Change from pre (baseline) to post scores (30 minutes later)
Participants are asked to rate adjectives regarding their current mood (positive and negative) at two time points (baseline and after body scan or active control intervention) on a questionnaire. Change scores are calculated (post- minus pre-scores). Instrument: Positive and Negative Affect Scale (PANAS) by Watson, Clark, and Tellegen (1988) is a self-report questionnaire that consists of two 10-item scales to measure both positive and negative affect. Each item is rated on a 5-point scale of 1 (not at all) to 5 (very much). Range for sum score of positive/negative affect: 10-50. For positive affect higher scores are better; for negative affect lower scores are better.
Secondary Outcomes
- Change in interoceptive accuracy(Change from pre (baseline) to post scores (30 minutes later))
- Change in heart rate variability (HRV)(Change from pre (baseline) to post scores (30 minutes later))
- Change in perceived stress(Change from pre (baseline) to post scores (30 minutes later))
- Change in state anxiety and depression(Change from pre (baseline) to post scores (30 minutes later))
