Die Daten entstammen der PRINT-Studie ("Überprüfung einer proaktiven Expertensystemintervention zur Prävention und Beendigung von riskantem Alkoholkonsum"), einer randomisiert-kontrollierten Interventionsstudie. Die Stichprobe aus Alkoholkonsumentinnen aus der Allgemeinbevölkerung (N = 1646) wurde zufällig in Interventions- und Kontrollgruppe aufgeteilt. In die Studie wurden alle Alkoholkonsumentinnen eingeschlossen, unabhängig von der Konsummenge. AlleStudienteilnehmerinnen wurden zu Baseline, nach 3, 6, 12 und 36 Monaten standardisiert befragt. Die Interventionsgruppe erhielt drei individualisierte Feedbackbriefe zu Baseline, nach 3 und 6 Monaten. Die Briefe wurden automatisch von einem computerbasierten Expertensystem nach vorher definierten Entscheidungsregeln zusammengestellt und basierten auf den Selbstberichtsangaben der Studienteilnehmerinnen zu den jeweiligen Messzeitpunkten. Die Briefe enthielten individualisierte Rückmeldungen zum Alkoholkonsum, zum alkoholbezogenen Risiko, zur Veränderungsmotivation sowie zu weiteren psychologischen Variablen (Selbstwirksamkeit, Entscheidungsbalance, Verhaltensänderungsstrategien). Die Intervention basierte auf dem Transtheoretischen Modell der Verhaltensänderung. Die Kontrollgruppe erhielt keinerlei Rückmeldungen. Das Ziel war eine Reduktion der durchschnittlichen Trinkmenge nach 12 bzw. 36 Monaten.

The data come from the PRINT study ("Testing a proactive expert system intervention to prevent and to quit at-risk alcohol use"), a randomized controlled trial. The sample of alcohol consumers from the general population (N = 1646) was randomized into an intervention and control group. All alcohol consumers were included in the study, regardless of the amount consumed. Standardized assessments took place at baseline, 3, 6, 12 and 36 months. The intervention group received three individualized feedback letters at baseline, after 3 and 6 months. The letters were automatically compiled by a computer-based expert system according to predefined decision rules and were based on the self-report data of the study participants at the respective measurement points. The letters contained individualized feedback on alcohol consumption, alcohol-related risk, motivation to change and other psychological variables (self-efficacy, decision balance, behavior change strategies). The intervention was based on the Transtheoretical Model of Behavior Change. The control group did not receive any feedback. The aim was to reduce the average amount of drinking after 12 or 36 months.
