The goal of this clinical trial is to evaluate the effectiveness of the 4-Step Training Program for Social Media Addiction (4-STEP-TPS) in reducing social media addiction, doomscrolling, cyberchondriac behavior, depressive symptoms, and health anxiety among young adults. The study aims to promote healthier digital habits, psychological well-being, and improved daily functioning. Participants with elevated social media addiction will complete a 4-week intervention with one session per week. They will be randomly assigned to either an intervention group or a waitlist control group. Pre- and post-intervention assessments will be conducted to determine the program's effectiveness.
