Cohort Study on Substance Use Risk Factors (C-SURF)

C-SURF is a 4-wave panel study on substance use and other non-substance related behaviors in a representative sample of 6000 young Swiss men. The first wave started in the years 2010-2012 when men were around 20 years of age and the last assessment was done in 2019-2020 when men were around 28 years. Besides substance use and behavoural addictions a multitude of behavioural, personal and environmental factors were measured (e.g. family background, personality, mental health, physical activity, etc). Measures are based on self-reported questionnaires.
