Clinical Trial Summary

To examine whether variation in 'risk-taking' personality and linked genetic variants predicts susceptibility to, and resilience against, stress-induced alcohol misuse.

Description:

Alcohol misuse is a global health issue responsible for over 1 million hospital admissions per annum in the UK with a combined cost of approximately £21 billion. Chronic alcohol misuse in patients who attend hospital for alcohol-related illness/injury is common, with relapse and recidivism almost ubiquitous. Patients often report that 'stress' was a catalyst for their drinking episodes, but we do not know exactly who is most at risk, how stress leads to drinking, or the genetic basis for this risk. This research aims to seek to identify patients at higher risk of stress-induced alcohol misuse, or who are more resilient to stress in this context, using a combination of analyses ranging from genetic variants to personality tests and clinical follow-up. The ultimate goal is that patients engaging with alcohol services can receive personalised and focussed treatment and enhance recovery

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Alcohol misuse	Measured using the alcohol use disorders identification test (AUDIT) (higher the score the worse the outcome)	immediately after the procedure
Primary	Recent stressors	Measured using the 30 item Stress Overload Scale questionnaire (higher the score, the worse the outcome)	Immediately after the study visit
Primary	Life Events	Measured using the Life Events Checklist Questionnaire (the higher the score the worse the outcome)	Immediately after the study visit
Primary	Impulse Behaviour	Measured using the the Urgency, Premeditation (lack of), Perseverance (lack of), Sensation Seeking, Positive Urgency, Impulsive Behavior Scale (UPPS-P) higher values indicate more impulsive behavior.	Immediately after the study visit
Primary	Risk taking behaviour	Measured by the Stop Signal Reaction Time Task (computer task) which measures the ability to inhibit a planned response	Immediately after the study visit
Primary	Molecular Anaylsis	Cheek swabs will be taken from all participant to carry out genomic DNA analysis	Immediately after the study visit
