Endless Scrolling: Predictors of Procrastinatory Short-Form Video Use and Its Effects on Stress and Sleep

Unhealthy social media habits may foster procrastination, leading to negative psychological and behavioral outcomes. The rising prevalence of procrastinatory short-form video (SFV) use (e.g., on TikTok, Instagram Reels, YouTube Shorts) highlights the need to better understand how established predictors of problematic media use operate in this emerging media environment. To address this gap, this study investigated the motivational factors underlying procrastinatory SFV use and its relationship with user well-being. Using an online survey of college students ( N = 549) from two U.S. universities, structural equation modeling revealed that individuals with lower self-control, stronger habitual SFV use, and greater involvement (enjoyment, escapism, and social connectedness) were more prone to procrastinatory SFV use, which in turn was associated with higher stress levels, poorer overall sleep quality, longer sleep latency, more sleep disturbances, and greater daytime dysfunction, but not with academic performance. This study contributes to the understanding of motivational factors underlying procrastinatory SFV use and its associations with user well-being. Theoretical contributions to the study of irrational media use, practical recommendations for mitigating procrastinatory SFV engagement, and directions for longitudinal and context-sensitive future research are discussed.
