The advent of TikTok use over the past couple years by young adults is not a unique phenomena – many different social media platforms pop up from year to year and attract a large userbase before eventually falling into disuse. However, between the addictive, short-form media format and the aggressive algorithm that TikTok employs to hook its users, it seems like TikTok is here to stay. The study that Dr. Benjamin Johnson and I propose to do aims to identify the link between TikTok, interactions with sponsored content (advertisements, brand deals, product placement, etc.) and psychological factors like self-esteem, self-control, boredom, materialism, mental health, and consumer behavior. To provide a picture of cause and effect (e.g., does impulsiveness lead to TikTok use, or does TikTok heighten impulsiveness?), a longitudinal survey will examine user experiences with this popular and unique app. A multi-wave panel study with a convenience sample of young adults will be used to test hypotheses.
