About this study

Official title: Stress-related Predictor Profiles for Craving and Relapse in Human Addiction

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.

Read the detailed description

In patients with Alcohol Use Disorder (AUD) stress exposure is known to affect craving, cue-reactivity and relapse risk. 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 (1) alcohol craving and related markers (attentional bias to alcohol-cues, implicit association task, neural cue-reactivity), (2) their predictive capacity for future alcohol intake, (3) the identification their neural correlates in brain circuits of motivational, cognitive, and affective processing. In addition to applying established stress-related markers (cortisol in saliva, heart-rate variability, systolic blood pressure and electrodermal activity), (4) we will integrate portable sensors (wearables) to allow a future integration in ambulatory assessments and to test innovative measures currently under investigation (e.g. voice stress analysis) to identify whether these additional parameters increase the predictive significance. Our 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.

  11. 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]

  13. 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.)

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 4 inclusion and 9 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 15 Sep 2023. 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 heart rate (time frame: 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). The study lists 15 primary outcomes in all. 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 15 Sep 2023.
