The COVID-19 outbreak has forced countries to introduce severe restrictive measures to contain its spread. In particular, physical distancing and restriction of movement have had important consequences on human behaviour and potentially also on illicit drug use and supply. These changes can be associated with additional risks for users, in particular due to reduced access to prevention and harm reduction activities. Read More

Shyness and susceptibility to social influence: Stronger concordance between norms and drinking among shy individuals.

Addict Behav 2021 Mar 26;119:106922. Epub 2021 Mar 26.

Rowan University, United States. Electronic address:

Despite a large body of work exploring associations between perceived norms and drinking and norms-based interventions for drinking, less work has examined moderators of associations between norms and drinking outcomes to determine potential sub-groups that might benefit most from brief norms-based interventions. The present study investigates shyness as a moderator of associations between drinking norms and alcohol use. We hypothesized that shyness would moderate associations between drinking norms and alcohol use such that individuals who are higher in shyness might be more sensitive to social influence and thus show stronger associations between drinking norms and alcohol use.
