Objective: This study intended to classify subtypes of Korean adolescents with suicidal ideation based on mental health problems and to explore the relationship between such subtypes and individual-, school- and community-level factors. Method: Data from high school freshmen who participated in the 2013 school-based mental health screening test and data about school and community variables obtained from public sources were combined and analyzed. A multilevel latent profile analysis using mental health issues as class indicators that included several predictors was conducted. Results: Three latent profiles were identified: Group 1 (6.5%) had high scores for both the internalizing and externalizing problems; Group 2 (40.2%) had high scores for internalizing problems, such as depression and mood related symptoms; and Group 3 (53.3%) had lower scores for all mental health problems compared to Groups 1 and 2. Gender, peer conflict, family conflict and academic problems were significant predictors at the individual level; school dropout rate was a significant school-level variable; and percent of youth in the total population, availability of mental health services, number of social welfare facilities and percentage of the total budget devoted to education/welfare were significant community-level variables. Conclusion: The present findings suggest that adolescents with suicidal ideation can be classified into several distinct subtypes based on mental health problems. These profiles and their associated covariates will aid in the establishment of youth suicide prevention policies. [ABSTRACT FROM AUTHOR]

The aim of this study was to investigate the risk factors for suicidal ideation in adolescents by gender and age. This study used 2013 nationwide school-based mental health screening test data from 591,303 seventh grade students and 618,271 tenth grade students in Korea. Suicidal ideation, four psychological problems, and three adverse life events were evaluated using the Adolescents Mental Health and Problem Behavior Screening Questionnaire-II. Of all students, 12.9-14.7% of the boys and 17.1-23.2% of the girls had suicidal ideation. Mood had the greatest impact on the risk for suicidal ideation and other factors also significantly increased the risk of suicidal ideation. Distractibility was positively related to suicidal ideation only in seventh grade students and behavioral problems increased suicidal ideation more in girls than in boys. Violence constituted the most powerful factor for suicidal ideation among the events; however, bullying constituted the most important event that increased suicidal ideation in seventh grade girls. All factors except ‘Distractibility’ increased the risk of severe suicidal ideation. The risk factors for suicidal ideation in adolescents differed by gender and age. Interventions should be made according to these characteristics to reduce suicidal ideation in adolescents. [ABSTRACT FROM AUTHOR]

In the last few decades, changing socioeconomic and family structures have increasingly left children alone without adult supervision. Carefully prepared and limited periods of unsupervised time are not harmful for children. However, long unsupervised periods have harmful effects, particularly for those children at high risk for inattention and problem behaviors. In this study, we examined the influence of unsupervised time on behavior problems by studying a sample of elementary school children at high risk for inattention and problem behaviors. The study analyzed data from the Children's Mental Health Promotion Project, which was conducted in collaboration with education, government, and mental health professionals. The child behavior checklist (CBCL) was administered to assess problem behaviors among first- and fourth-grade children. Multivariate logistic regression analysis was used to evaluate the influence of unsupervised time on children's behavior. A total of 3,270 elementary school children (1,340 first-graders and 1,930 fourth-graders) were available for this study; 1,876 of the 3,270 children (57.4%) reportedly spent a significant amount of time unsupervised during the day. Unsupervised time that exceeded more than 2h per day increased the risk of delinquency, aggressive behaviors, and somatic complaints, as well as externalizing and internalizing problems. Carefully planned afterschool programming and care should be provided to children at high risk for inattention and problem behaviors. Also, a more comprehensive approach is needed to identify the possible mechanisms by which unsupervised time aggravates behavior problems in children predisposed for these behaviors.
