Background: Alcohol is often consumed in social contexts. An emerging social context in which alcohol is becoming increasingly apparent is social media. Young people increasingly display alcohol-related posts ("alcoholposts") on social networking sites such as Facebook and Instagram. Objective: Considering the importance of social aspects for both alcohol consumption as well as social media use, the current study investigated (1) the social content of alcoholposts (i.e., the evaluative social context and presence of people) and (2) social processes (i.e., the posting of and reactions to posts) involved with alcoholposts on social networking sites. Methods: An extensive content analysis of Facebook and Instagram-profiles (N = 192) was conducted. Results: It was shown that the alcoholposts of youth frequently depicted alcohol in a positive social context and displayed people holding drinks. In addition, alcoholposts were more often placed on participants' timelines by others (i.e., by tagging) than they were posted by participants themselves. Furthermore, it was revealed that such social posts received more likes and comments than non-social posts (e.g., in which no people were visible). Conclusions: Thus, both in terms of content as well as processes, alcoholposts on social media are social in nature, and a part of young people's everyday social lives.Interventions aiming to decrease alcoholposts should therefore focus on the broad social context of individuals in which posting about alcohol takes place. Europe and the United States showed that 35% of youth who consume alcohol had at least one binge drinking episode in the past month [5][6][7]. This high prevalence of alcohol use and the multitude of negative related consequences increase the need to gain more insight into the context in which this behavior takes place. Research has shown that alcohol is often consumed in social contexts [8]. Moreover, an emerging social context in which alcohol is becoming increasingly apparent is that of the social media. That is, young people increasingly display alcohol-related posts ("alcoholposts") on social networking sites such as Facebook and Instagram [9]. The current study investigates these alcoholposts on social media, and how social these posts actually are, by conducting a content analysis of alcoholposts on Instagram and Facebook among 192 adolescents and young adults.
The social context of alcoholYoung people often consume alcohol in social contexts, such as dinners and parties, and alcohol consumption is often referred to as a social activity [8,10,11]. Moreover, research has shown that alcohol consumption plays a large part in young peoples' social lives and social identity exploration [12]. Furthermore, many studies have shown that social norms are strongly related to adolescent alcohol use, especially when these norms originate from peers [2]. The importance of the social environment for alcohol consumption is also apparent from the vast amount of research demonstrating the effects of peer influence a...
