                  The purpose of this cross-sectional study was to test the Rungsang-Chaimongkol Model of Suicidal Ideation among Thai Adolescents. A multi-stage random sampling technique was used to recruit a sample of 437 adolescents attending secondary schools in a central province of Thailand. Research instruments were self-report questionnaires, including the Scale for Suicidal Ideation, the General Health Questionnaire, the Strengths and Difficulties Questionnaire, the Rosenberg Self-Esteem Scale, and the Negative Event Scale. Descriptive statistics and structural equation modeling were used to explore the magnitude of direct and indirect effects on the suicidal ideation among the sample.
                  Results revealed that negative psychological attributes and stressful events had a direct positive effect on suicidal ideation. Overall distress mediated the link between negative psychological attributes and stressful events, and suicidal ideation. The Model accounted for 32% of the overall variance in prediction of suicidal ideation among Thai adolescents. These findings suggested that the intervention program to prevent suicidal ideation aiming at decrease negative psychological attributes, stressful events and overall distress would be beneficial. However, it requires further testing with other groups.
