Not Applicable

Completed

• Conditions: Mindfulness; Working Memory; Stress; Mood

• Registration Number: NCT03148678
• Lead Sponsor: University Hospital, Basel, Switzerland

Brief Summary

The overall goal of the outlined study is to scrutinize and to promote mindfulness via new technologies using a combination of smartphone-based assessment and micro-interventions, fMRI and real-time fMRI-neurofeedback.

Detailed Description

The overall goal of the outlined study is to scrutinize and to promote mindfulness via new technologies using a combination of smartphone-based assessment and micro-interventions, fMRI and real-time fMRI-neurofeedback. More specifically, we aim to i) evaluate whether smartphone-based micro-interventions affect mindfulness, stress, and mood, ii) evaluate whether mindfulness, its neural substrate, and related mental and physiological functions can be modified by training volitional control over brain activity by means of real-time functional magnetic resonance imaging neurofeedback (RT-fMRI-NF), iii) differentiate neural activation patterns during mindfulness vs. mind wandering.

Primary Outcome Measures

Name	Time	Method

Subjective mood assessed by Multidimensional Mood State Questionnaire	Daily, during smartphone-based micro-interventions (duration: 10 days); on 1 day, which is the laboratory assessment day (scheduled 1 day subsequent to the last smartphone-based micro-intervention days)	Subjective mood, assessed via Multidimensional Mood State Questionnaire (MDMQ)
Subjective stress reactivity assessed by Visual Analog Scale	Daily, during smartphone-based micro-interventions (duration: 10 days); on 1 day, which is the laboratory assessment day (scheduled 1 day subsequent to the last smartphone-based micro-intervention days)	Subjective stress reactivity, assessed via Visual Analog Scale (VAS)
State mindfulness assessed by State Mindfulness Scale	Daily, during smartphone-based micro-interventions (duration: 10 days); on 1 day, which is the laboratory assessment day (scheduled 1 day subsequent to the last smartphone-based micro-intervention days)	State mindfulness, assessed via State Mindfulness Scale (SMS)

Secondary Outcome Measures

Name	Time	Method
Working Memory assessed by N-back task test	On 1 day, which is the laboratory assessment day (scheduled 1 day subsequent to the last of the 10 smartphone-based micro-intervention days)	Assessed via N-back task (visual single-3-back with letters as stimuli)
