The 3,374 students were systematically drawn from junior high school in 3 districts in Bangkok and 17 provinces across the country. Three kinds of tools were administered: 1. National Youth Risk Behavior Survey 2015 (YRBS) 2. Thai Youth Checklist: Self-Report 3. Thai Diagnostic Interview for Children and Adolescents-Revised (T-DICA-R). Descriptive statistics and univariate correlation analysis were analyzed.
          Results After data weighting, any bullying experience in 1 year of Thai students was 21.0 percent which most of them were male 55.1 percent, average age 14.8 years old. The prevalence of bullying in male and female were 23.4 percent and 18.7 percent respectively. The prevalence of psychiatric disorders in students with any bullying experience was 60.1 percent. The three most common psychiatric disorders were disruptive behavior disorders, anxiety disorders and mood disorders. Students experiencing any bullying have 2.6 times higher chance of psychiatric disorders than students without experiences. In particular, the mixed group has 8.6 times higher.
          Conclusion One year prevalence of any bullying experiences in Thai secondary school students was 21.0 percent and 60.1 percent of them had psychiatric disorders and they have a 2.6 times higher chance of psychiatric disorders. Screening for bullying experiences in school setting was easy and the public health services should be alliance with schools to prevent psychiatric disorders and increase service accessibility.
