Short description

Individuals with substance use disorders challenge the health care system. The Addiction Research Group seeks to contribute to a better understanding of neurophysiological processes in substance use disorders (e.g. alcohol cue reactivity, behavioural inhibition, cortisol levels) and to the improvement of substance use disorder treatment programs by developing add on-interventions designed to lower the risk of relapse. Predictors of treatment outcome such as psychiatric comorbidity (e.g., Attention Deficit/Hyperactivity Disorders, Posttraumatic Stress Disorders) or substance use-related self-efficacy are of particular interest.
