Mental health curriculum interventions using social media have been associated with positive implementation outcomes. This study aimed to investigate whether such an intervention significantly improves adolescent mental health literacy and is associated with positive implementation outcome measures.Methods: This study employed a quasi-experimental design, comparing the before-and-after difference between the intervention group (n1=77) and the control group (n1=76). A mental health literacy module was delivered using social media. Data were collected using validated questionnaires. Effect size and difference-in-differences model calculations (and associated 95% confidence intervals, CI) were conducted alongside other descriptive analyses.Results: The estimated intervention effect size and difference-in-differences estimates were greater than zero. The effect was greater in the intervention than in the control group (p< 0.05) despite sex and age differences. The effect size estimate provided by Cohen’s d and Hedges’ g values was medium-to-large (d/g=0.429– 0.767, p< 0.05). The difference-in-differences reflected a significant effect (DID=0.348, CI: 0.154– 0.542, p< 0.001) in increasing mental health literacy despite differences associated with sex, age, and school grade. The intervention program was acceptable, appropriate, feasible, and satisfactory, and more than 80% of participants said they agree to completely agree with these implementation outcomes. Resources and personal and family-related factors were among the perceived influencing factors determining the effectiveness and implementation outcome measures.Conclusion: The intervention program effectively improved the mental health literacy of adolescents. It has been highlighted that social media interventions for mental health promotion could be practical and scalable; however, there is a need to take into account socio-demographic differences and barriers to inclusion/compliance.Keywords: adolescent mental health, mental health promotion, difference-in-differences, effect size
