Objectives: Digital game addiction and cyberbullying are two common and significant public health issues among adolescents. The present study was conducted to measure the effect of motivational interviewing-supported health education in reducing digital game addiction and cyberbullying behaviors in adolescents. Study design: A parallel-group randomized controlled trial was adopted. Methods: The study population consisted of ninth-grade adolescents studying in a single high school in the capital city of T & uuml;rkiye. The study included 52 adolescents (experiment: 26; control: 26). Data were collected using the Personal Information Form, the Digital Game Addiction Scale (DGAS-7), and the Renewed Cyberbullying Inventory-II. Motivational interviewing-supported health education program, including six sessions, was implemented for the experiment group to reduce digital game addiction and cyberbullying behaviors. Instruments were given to the experiment and control groups at baseline (before the intervention) and post-test (after the intervention). A chi-square test, a two-way mixed-design variance analysis, and a Bonferroni test were used to analyze the data. Results: There was no statistically significant difference between the experiment and the control groups regarding digital game addiction, cyberbullying, and cyber victimization baseline mean scores (p > 0.05). After the intervention, digital game addiction, cyberbullying, and cyber victimization post-test mean scores in the experiment group decreased significantly compared to the control group (p < 0.005), highlighting the short-term outcomes. The intervention revealed large effect sizes, with partial eta-squared values of 0.339, 0.428, and 0.161, respectively. Conclusions: The study concluded that health education-supported motivational interviewing was effective in reducing digital game addiction and cyberbullying behaviors in adolescents.
