The increased popularity of social media has brought clinicians and researchers to question the potential problematic outcomes of such Internet-based applications. Over the past two decades, an increasing number of studies identified the so-called problematic use of social media (PUSM), which led to the development of various assessment tools requiring constant revisions because of the ever-evolving nature of the Internet. This review summarizes the most frequently used measurement tools in PUSM research while suggesting best practices and directions for future research based on the most recent evidence in the field.
