Anger as a predictor of suicidal ideation in middle-school students in Korea: gender difference in threshold point.
Studies on gender differences in suicidal ideation and anger are limited. Furthermore, these studies focused on linear relationships, which limits the full understanding of the complex relationships and hampers identification of high-risk groups for suicidal tendencies. Hence, this study aims to assess the gender differences in: (1) the level of suicidal ideation and anger; (2) predictors for suicidal ideation; and (3) the varying association between suicidal ideation and anger. The target population for this cross-sectional, correlational study was adolescents aged 13 to 15 years living in South Korea. A total of 258 adolescents (160 boys and 98 girls) completed the Multidimensional Anger Inventory and Suicidal Ideation Questionnaire. Data were analyzed by descriptive statistics, multiple linear, and spline regression analysis. Girls reported significantly higher scores in both anger and suicidal ideation. While anger was a significant predictor for suicidal ideation only in boys, both school life satisfaction and anger were significant predictors of suicidal ideation in girls. After controlling for sociodemographic factors, the spline regression revealed a significant threshold point in the relationship between anger and suicidal ideation, particularly among girls. At the threshold anger point of 117.67, 12.5% of girls belonged to the high-risk group. The gender-specific patterns of the relationship between suicidal ideation and anger and the existence of threshold points confirmed the need for targeted suicidal preventive programs focusing on controlling anger.
