Effects of a group activity-based motivational enhancement therapy program on social media addictive behaviors among junior high school students in Thailand: a cluster randomized trial.

Purpose: This study aimed to assess the effects of a group activity-based motivational enhancement therapy (GA-MET) program on social media addictive behaviors among junior high school students.

Materials and methods: This cluster randomized trial was performed in 245 junior high school students who used social media in the lower part of northeast Thailand. The GA-MET program group and the control group sessions lasted 8 weeks and were followed up 4 weeks later. The addictive social media behaviors, average duration of social media usage during weekdays and weekends (hours/day), child behaviors, self-esteem, and depression were investigated using a self-reported questionnaire. Multivariable linear regression was used to compare the mean and 95% CIs between two groups.

Results: The GA-MET program significantly decreased the average duration of social media usage during weekdays and weekends (hours/day) (-1.27, 95% CI: -2.18,-0.37 and -1.25, 95% CI: -2.22, -0.29, respectively), emotional behavior (-0.69, 95% CI: -1.18, -0.19), and depression (-4.03, 95% CI: -6.07, -1.99) in the treated group compared to the control group.

Conclusion: The GA-MET program could reduce the risk of social media addictive behaviors in junior high school students in Thailand by decreasing time spent on social media, emotional behaviors, and depression.
