Beschreibung
High impulsivity and low inhibitory control as well as related neural markers are indicated as risk factors for substance use disorders (SUDs). Yet, it has never been tested whether the association of these factors with SUDs may be attributable to differences in the degree of substance use. Thus, this project aims to examine whether these risk factors specifically predict a higher risk to develop substance-related problems when statistically controlling for the degree of use. To achieve this, we will assess impulsivity, inhibitory control, and their neural correlates (deriving individual neural markers) using fMRI and dimensional measures of the degree of substance use and related problems in (poly-)substance users of varying degrees of substance use. To test whether the neural markers of impulsivity and inhibitory control predict prospective changes in substance-related problems, we will assess substance use variables again twelve months after the fMRI session. We expect that impulsivity, inhibitory control, and related neural markers will (cross-sectionally and prospectively) predict substance-related problems above and beyond the degree of substance use.
