Trial 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. Read more about this study

About this study

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.

Read the 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.

Being tested
Body Scan, Audio-book

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Body ScanBehavioural

    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-bookOther

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

Audio-guided mindfulness-based intervention (body scan)ExperimentalNot described
Receives: Behavioral: Body Scan
Enhanced Audio-guided mindfulness-based intervention (body scan)ExperimentalParticipants 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in affect

    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.

    Measured: Change from pre (baseline) to post scores (30 minutes later)

Secondary outcomes (4)
  1. Change in perceived stress

    Participants are asked to rate how stressed they feel at the moment at two time points (baseline and after body scan or active control intervention) on a questionnaire (VAS: item ranges from 0 (not stressed at all) - 100 (very stressed). Change scores are calculated (post- minus pre-scores). More negative change scores are better since it indicates a stronger stress reduction (maximum reduction: -100). Higher positive change scores are worse since this indicates an increase in perceived stress (maximum increase: +100). Range of change scores: -100 - +100).

    Measured: Change from pre (baseline) to post scores (30 minutes later)

  2. Change in heart rate variability (HRV)

    Heart rate variability (HRV) describes the variations between two successive heart beats and is considered a measure for cardiac adaptation to internal and external stimuli. HRV is considered an important transdiagnostic biomarker of health. HRV is frequently quantified using time- domain measures such as the standard deviation of NN intervals (SDNN) and the root mean square of successive differences between normal heartbeats (RMSSD). For HRV levels higher scores are better

    Measured: Change from pre (baseline) to post scores (30 minutes later)

  3. Change in interoceptive accuracy

    The heartbeat perception task (Schandry, 1981) encompasses several trials in which participants are instructed to silently count their heartbeats and report the number they counted after each trial. Reported and actual number of heart beats (as assessed by ECG) will be used to calculate a heartbeat detection index (error score).

    Measured: Change from pre (baseline) to post scores (30 minutes later)

  4. Change in state anxiety and depression

    The State-Trait-Anxiety-Depression-Inventory (STADI) (Laux, L. Hock, M., Bergner-Köther, R., Hodapp, V. \& Renner, K., 2013) measures participants' state anxiety (10 items) and state depression (10 items) severity. Each item can be answered on a 4-point-scale from 1 (not at all) - 4 (very much). Sum scores are calculated and range from 10-40 for each scale (depression and anxiety). Lower scores indicate lower severity (i.e., less negative mood).

    Measured: Change from pre (baseline) to post scores (30 minutes later)

Questions about this trial

What is this clinical trial studying?

A study testing Body Scan and Audio-book in people with Healthy Participants, run by Philipps University Marburg at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in affect (time frame: Change from pre (baseline) to post scores (30 minutes later)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2024.
