First Comes Substance Use, Then Comes Social Media Posts? Examining the Temporal Ordering and Relative Strength of Relations Across Alcohol, Tobacco and Marijuana Use and Posting Behavior

Social media posts represent a major route by which youth share their substance use cognitions and experiences with others. Extant research has primarily examined relations between alcohol-related posts and posters' own alcohol use, yet little is known about the role of social media in the use of less socially accepted substances, namely tobacco and marijuana. Our study represents the first to examine the relative strength of this relation across alcohol, tobacco, and marijuana. The current research used a one-month time lag to tease apart the temporal ordering of substance-use-posting and participants' own substance use. A sample of 282 15-20-year-olds (Mage = 18.4, SD = 1.3, 52.9% female) in the United States completed two self-report surveys, one month apart. Results of a cross-lagged panel model revealed significant effects of alcohol and marijuana consumption on subsequent alcohol- and marijuana-related posting, respectively (i.e., selection effects). However, reverse relations (i.e., self-effects) were not significant. Further, we found no differences in the strength of selection effects across substances, suggesting they are similar for both more (alcohol) and less (marijuana and tobacco) socially acceptable substances. Results point to the importance of using young people's social media posts as a way to help identify individuals at risk for heightened substance use and social media as a mechanism for targeted prevention programming.

A game of persuasion: influencing persuasive game appraisals through presentation frames and recommendation sources

Introduction

As games made with the explicit or implicit purpose of influencing players' attitudes, persuasive games afford a new way for individuals to reflect and elaborate on real-world issues or topics. While research points to effects of these games on their players, little is known about their practical impact. The current study focuses on the decision-making process that takes place between first hearing about a game and deciding to play it. Three elements in a game's presentation to potential players were explored: (1) the way it is framed as an entertaining experience, (2) the way it is framed as intending to persuade its players, and (3) whether it comes recommended by automated systems or through electronic word-of-mouth. These factors were chosen in line with theoretical arguments around framing, eudaimonia, and source credibility.

Methods

A two (entertainment frame: hedonic versus eudaimonic) by two (persuasive intent frame: obfuscated versus explicit) by two (source of recommendation: system- versus peer-based) between-subjects experimental design was performed across (N = 310) randomly distributed participants. Measures were adapted from previous research and included selection and play behavior, attitudes, and obtrusiveness of persuasive intent, among others.

Results and Discussion

Results show that frames need to be congruent to be effective, with the most effective stimuli being those where persuasive intent was clear and players could expect to engage meaningfully. Peer recommendations led to greater play intention than system-based varieties. While intention to play positively related to actual play behavior, this relationship was likely the result of avid game players displaying more interest in the game regardless of the study's manipulations. Implications are drawn from the advantages of being open about persuasive intent and the composition and drivers of a persuasive game's target audience.
