Systematic Bias in Self-Reported Social Media Use in the Age of Platform Swinging: Implications for Studying Social Media Use in Relation to Adolescent Health Behavior.

Public health researchers are increasingly interested in the potential relationships between social media (SM) use, well-being, and health behavior among adolescents. However, most research has assessed daily SM time via self-report survey questions, despite a lack of clarity around the accuracy of such reports given the current tendency of youth to access SM on multiple electronic devices and cycle between multiple SM platforms on a daily basis (i.e.

"Follow my Finsta": Drinking trajectories in relation to auxiliary Instagram accounts.

Objective: This study explored the burgeoning youth practice of possessing a fake, secondary Instagram account known as a "Finsta" in relation to exposure to alcohol-related content and college drinking.

Participants: First-year university students with at least a primary Instagram account ( = 296) completed online surveys.

Method: Surveys assessed whether participants did or did not have a Finsta pre-matriculation (T1), Instagram alcohol content exposure one month into college (T2), and alcohol use at T1 and near the end of the first year (T3).

Integrating social media inspired features into a personalized normative feedback intervention combats social media-based alcohol influence.

Backround: Research suggests that the social media platforms popular on college campuses may reflect, reinforce, and even exacerbate heavy drinking practices among students. The present study was designed to directly examine: (1) whether exposure to alcohol-related content on social media diminishes the efficacy of a traditional web-based personalized normative feedback (PNF) alcohol intervention among first-year drinkers; and (2) if social media inspired features and digital game mechanics can be integrated into a PNF intervention to combat social media-based alcohol influence and increase efficacy.

Method: Alcohol experienced first-year college students (N = 223) completed a pre-survey that assessed exposure to alcohol-related content and social media and were randomized to 1 of 3 web-based alcohol PNF conditions (traditional, gamified only, or social media inspired gamified).
