Design of the study: Baseline and one year follow-up of a prospective-longitudinal community study. Setting of the study: Clinical interviews and behavioural tasks in the laboratory. Participants: 338 individuals between age 20 and 26 were selected from a random sample from the registration office files of Dresden, Germany. Participants fulfilled the criteria for one of three groups: SUD, ND, or healthy controls. After one year, we assessed 313 participants again (93%). Measurements: ND and SUD severity were operationalized with number of DSM-5 symptoms (partly modified for ND) and quantity-frequency indices of use. Four tasks were applied to assess independent facets of impulsive decision-making: 1) delay discounting, 2) risk seeking for gains and 3) for losses, and 4) loss aversion. 2018-01-01T00:00:00Z
