Psychosocial problems and suicidal ideation in Chinese adolescents: findings from a longitudinal study.

Background: Few studies have explored the important role of different dimensions of emotional and behavioral problems (EBPs), perceived social support and loneliness in predicting suicidal ideation among Chinese adolescents. Based on a 6-month longitudinal study conducted in Taizhou high schools, we aimed to explore the associations between psychosocial problems and suicidal ideation in Chinese adolescents, and to ascertain whether co-occurring psychosocial problems increase suicidal ideation.
Methods: A total of 3,267 students were eligible for this analysis. Perceived social support was assessed using the Multidimensional Scale of Perceived Social Support. Loneliness and suicidal ideation were assessed using the University of California, Los Angeles (UCLA) 3-Item Loneliness Scale and one item from the Children's Depression Inventory. The Strength and Difficulties Questionnaire assessed EBPs. Multivariable logistic regression models were used to estimate longitudinal associations between each psychosocial problem (lack of perceived social support from family, friends, and significant others, loneliness, emotional, conduct and peer problems, hyperactivity, and poor prosocial behavior) at baseline and suicidal ideation at follow-up. Multinomial logistic regression models were used to examine the association between the number of psychosocial problems at baseline and suicidal ideation at follow-up.
Results: The multivariable logistic regression results showed that after adjusting for baseline suicidal ideation, sociodemographic covariates and depressive symptoms, low level of perceived social support from family (OR =1.78; 95% CI: 1.10-2.87), emotional problems (OR =2.35; 95% CI: 1.41-3.79), and poor prosocial behavior (OR =1.74; 95% CI: 1.08-2.79) were significant predictors of suicidal ideation among the adolescents. The risk of suicidal thoughts increased as the number of psychosocial problems increased. The participants with five or more psychosocial problems had a higher risk of having serious suicidal thoughts than those with no problem (relative risk ratio =4.50; 95% CI: 2.13-9.49).
Conclusions: The study confirmed the predictive role of multiple psychosocial problems on suicidal ideation, and the accumulative effect of co-occurring psychosocial problems in magnifying the risk of suicidal ideation. More integrated and holistic approaches need to be taken to identify high-risk groups and provide interventions of suicidality in adolescents.
