The aim of the study is to evaluate the effectiveness of long-term and short-term app-based self-guided psychological interventions to reduce craving and lapse risk in users with substance use disorder or problematic substance use (alcohol and stimulants). Participants are randomly assigned to thirteen different groups to compare the effectiveness of particular long-term interventions. A questionnaire battery assessment is administered (1) at baseline in the first week following onboarding in; (2) after 5 weeks; (3) after six months. In addition, longitudinal data on several variables related to craving and lapse risk are collected daily using ecological momentary assessment.
