NCT03810924

Brief Summary

Long-term aim is the definition of a setup of mobile sensors and their integration in a mobile infrastructure that allows the prediction of stress related alcohol intake in an ambulatory setting. Here, we aim to identify stress- and alcohol cue-related physiological markers in a lab experiment to assess interactions between acute psychological vs. physical stress exposure and alcohol cue-exposure regarding their effects on measures relevant for the development and maintenance of Alcohol Use Disorder (AUD). Further, we aim to identify neural correlates in brain circuits of motivational, cognitive, and affective processing. In addition to applying established stress-related markers, we will integrate innovative sensor-based measures.

Outcome Measures

Primary Outcomes (15)

  • change in heart rate

    heart rate acquired with ear clip (continuous time series)

    at examination day: continuous measurement throughout the whole experiment (except during MRI scanning); duration around 2 hours; starting 1 hour 50 minutes after arrival of the proband

  • change in heart rate variability

    heart rate variability acquired with ear clip (continuous time series)

    at examination day: continuous measurement throughout the whole experiment (except during MRI scanning); duration around 2 hour; starting 1 hour 50 minutes after arrival of the proband

  • change in blood pressure (systolic and diastolic)

    acquired with pressure sleeve

    at examination day: 6 time points measured throughout the whole experiment (except during MRI scanning); at hours:minutes 2:20, 2:50, 3:20, 3:50, 4:50, 5:05 after arrival of the proband

  • change in electrodermal activity

    time series acquired with body sensor

    at examination day: continuous measurement throughout the whole experiment (except during MRI scanning); duration around 2 hour; starting 1h 50min after arrival of the proband

  • neural alcohol-related cue-reactivity

    % signal change, measured with fMRI; paradigm Vollstädt-Klein et al. 2010; \[% signal change is not a change over time; it is measured during one experimental session\]

    at examination day: measured directly after the behavioral tasks at the end of the lab experiment

  • neural inhibition processing

    % signal change, measured with fMRI; stop-signal reaction time task (Fauth-Buhler et al. 2012) \[% signal change is not a change over time; it is measured during one experimental session\]

    at examination day: measured directly after the behavioral tasks at the end of the lab experiment

  • neural emotion processing

    % signal change, measured with fMRI; faces task (Hariri et al. 2002) \[% signal change is not a change over time; it is measured during one experimental session\]

    at examination day: measured directly after the behavioral tasks at the end of the lab experiment

  • resting state activity

    resting state connectivity measured with fMRI

    at examination day: measured directly after the behavioral tasks at the end of the lab experiment

  • fMRI

    neural alcohol-related cue-reactivity, stop-signal reaction time task, emotion processing and resting state fMRI

    at examination day: measured directly after the behavioral tasks at the end of the lab experiment

  • attentional bias to alcohol cues

    measured with reaction time differences (in milliseconds) using the dotprobe-task (Vollstädt-Klein et al. 2009) \[reaction time differences is not a change over time; it is measured during one experimental session\]

    at examination day: measured directly after the stress task / newspaper reading; before "implicit alcohol association" and MRI session

  • implicit alcohol association

    measured with reaction time differences (in milliseconds) using the implicit association task (Wiers et al. 2016) \[reaction time differences is not a change over time; it is measured during one experimental session\]

    at examination day: measured after the stress task / newspaper reading, directly after the "attentional bias to alcohol cues" ; before MRI session

  • change in level of cortisol

    cortisol measured in saliva as a stress marker

    at examination day: 6 time points measured throughout the whole experiment (except during MRI scanning); at hours:minutes 2:20, 2:50, 3:20, 3:50, 4:50, 5:05 after arrival of the proband

  • change in voice stress pattern

    audio file of participants' voice for voice stress pattern analysis will be recorded. From this a multivariate measure (i.e. multivariate vector) will be acquired (including frequency, loudness etc.)
