Adolescents' Drinking Behavior Off- and Online: Disentangling Exposure Effects and Selective Exposure in Networked Communication Structures.

This article applies a network approach to better understand the often-demonstrated link between adolescents' drinking behavior and their exposure to alcohol-related content on social media. Focusing on social dynamics among adolescents and their peers, we investigate the causes and consequences of exposure to individual peers who share alcohol-related content online. Drawing on social network literature and the perspective of networked communication online, we distinguish between exposure effects and selective exposure as the two core dynamics that can explain the association between drinking behavior and exposure to alcohol-related content online.

COVID-19 vaccination and changes in preventive behaviours: findings from the 2021 vaccine roll-out in Switzerland.

Background: Behavioural, environmental, social and systems interventions (BESSIs) remain important for controlling the COVID-19 pandemic in addition to vaccination. However, people's adoption of BESSIs may decrease as vaccination rates increase due to reductions in the perceived threat of disease, and changes in risk perceptions of behaviours that increase the chance of infection. Thus, we examined predictors of and changes over time in reports of mask wearing and physical distancing and whether changes in mask wearing and physical distancing differed by vaccination status during the main 2021 COVID-19 vaccine roll-out period in Switzerland.

Social Distancing during the COVID-19 Pandemic in Switzerland: Health Protective Behavior in the Context of Communication and Perceptions of Efficacy, Norms, and Threat.

The success of health protection measures depends on public compliance. This paper aims to understand the influence of three different types of communication (i.e.

Social Media Use in the Context of Drinking Onset: The Mutual Influences of Social Media Effects and Selectivity.

The article aims to provide a profound understanding of the multifaceted role of adolescents' social media use in the context of drinking onset. It differentiates between exposure and sharing effects from social media content on drinking behavior and, conversely, exposure to and sharing of alcohol-related content due to drinking in the initiation phase of regular alcohol consumption. We tested our hypotheses based on a two-wave survey among adolescents aged 13 to 17 and focused on those who had not yet been regular drinkers at the first wave of data collection ( = 406).
