Personalized normative feedback (PFI). The PFI was a single-session intervention; it was displayed in a single screenshot and addressed the participant by name. It consisted of a summary of the participant's weekly consumption, a comparison with maximum drinking limits and a graphical comparison of the participant's consumption to the average level in the municipality (gender-specific), followed by information about health and social risks of heavy drinking as well as links for further self-help material and a local alcohol treatment facility.
Self-help material (SHM). The SHM was a single-session intervention and was displayed in a single screenshot. It consisted of information about maximum drinking limits, followed by information about health and social risks of heavy drinking as well as links for further standardized self-help material and a local alcohol treatment facility.
