Web-based treatments have the potential to address low rates of help seeking due to their convenience, accessibility, and capacity to address barriers to health care access (eg, shame, stigma, cost, and access to expert care). However, web-based treatments for online behavioral addictions have not been systematically evaluated.<h4>Objective</h4>This review aimed to systematically describe the content of web-based treatments for online behavioral addictions and describe their therapeutic effectiveness on symptom severity and consumption behavior.<h4>Methods</h4>A database search of MEDLINE, EmbaJMIR mental healthe36662https://www.ebi.ac.uk/biostudies/studies/S-EPMC9508667biostudies-literatureContent and Effectiveness of Web-Based Treatments for Online Behavioral Addictions: Systematic Review.PMC9508667Rodda SNPark JJKing DLWilkinson-Meyers LfalseContent and Effectiveness of Web-Based Treatments for Online Behavioral Addictions: Systematic Review.<h4>Background</h4>Very few people seek in-person treatment for online behavioral addictions including gaming and gambling or problems associated with shopping, pornography use, or social media use.
