ABSTRACT
BACKGROUND: Since its launch in 2017, TikTok has rapidly emerged as a major player in the digital landscape, amassing over a billion active users. Its engaging features have raised concerns about potential problematic use and negative mental health outcomes. Despite increasing scholarly attention, a consolidated understanding of TikTok’s problematic use potential and implications remains elusive This systematic review synthesizes empirical research on problematic TikTok use and its impact on mental health.
METHODS: This review followed PRISMA Statement 2020 guidelines and conducted a comprehensive search across PubMed, Embase, Scopus, Web of Science, and PsycINFO databases until July 10, 2024. Keywords included terms related to TikTok use, addiction, and problematic use. Studies were included based on empirical focus and publication in peer-reviewed journals. Data extraction comprised study characteristics, measures of TikTok problematic use, and related mental health outcomes. Quality assessment used JBI, Cochrane’s RoB 2, MMAT, CASP, and NOS tools. The protocol was registered in OSF: https://osf.io/cjf97.
RESULTS: This review included 26 studies, involving a total of 11 462 participants. The pooled prevalence of TikTok use was estimated at 80.19%, with the highest rates observed among people aged 18 to 29 years, where it reached 85.4%. Frequent use of TikTok was closely linked with an increase in symptoms of anxiety and depression, especially in users aged under 24 years. Female users were more likely to experience problematic TikTok use, with 67.3% of such cases found among female university students. Moreover, higher addiction scores were noted among individuals from lower socioeconomic backgrounds and those who had higher levels of neuroticism.
CONCLUSION: The findings of this review highlight the growing concern surrounding the impact of problematic TikTok use on mental health, particularly among younger and more vulnerable populations. It is imperative for stakeholders to prioritize the integration of digital literacy and media literacy into educational curricula. Moreover, the involvement of caregivers through guided mediation and the establishment of clear usage parameters could play a crucial role in managing screen time, particularly for younger users. To improve the current landscape of empirical research, longitudinal and interventional research is warranted.
