From the hidden to the obvious: classification of primary and secondary school student suicides using cluster analysis.

BACKGROUND: Suicide is one of the leading causes of death in children and youth. Using a sample of fatal suicides among school-aged students in Hong Kong, this study aimed to demonstrate how the classification of children and adolescent suicides into distinct subgroups using cluster analysis can alert us to the heterogeneous nature of the student suicide population and increase our understanding of multidimensional underlying causes.  METHODS: Deaths by suicide of Hong Kong primary and secondary school students occurring between 2013-16 were identified. Reports were acquired from the Coroner's Court, Police Force, and Education Bureau in Hong Kong. Information about students' sociodemographic characteristics, suicide circumstances, stressors, and risk factors was extracted and organized for analysis. Based on the indicated stressors (school, family, close relationship, social challenge, finance, risk behaviour, suicide exposure, others) and risk factors (health and mental health, history of self-harm, suicidality, and psychological maladjustment), cluster analysis was conducted to derive distinct profiles of student suicides. RESULTS: A four-cluster solution was found. Patterns of stressors, risk factors, background characteristics and suicide circumstances within each cluster were examined. Four distinct and meaningful profiles of student suicides were characterised as "school distress", "hidden", "family and relationship", and "numerous issues". CONCLUSIONS: Findings highlighted the need to approach student suicides in meaningfully differentiated ways. Gathering suicide report data and generating evidence that advances our knowledge of student suicide profiles are important steps towards early identification and intervention.

A Community-Based Response to a Suicide Cluster.

Background: A 45-month community-based suicide prevention program was launched in response to the emergence of a suicide cluster in 2010 in Hong Kong. Aims: This study aimed to evaluate the effectiveness of the program, document the implementation and outcomes of the project, and identify factors that contribute to the outcomes. Method: The program was delivered following the five key components of the public health approach: (a) community consensus building; (b) surveillance and monitoring; (c) development of coordinated action strategies; (d) interventions development and implementation at the universal, selective, and indicated levels; and (d) program evaluation. Results: A significant decreasing trend of suicide was found in the study site during the intervention period, whereas no changes were found in the three control sites. Spatial analysis also showed that the suicide cluster subsided after the intervention. Three impacts and one challenge of the program were identified from the qualitative feedback of the program stakeholders. Limitations: More investigations should be made to assess the sustainability of this community-based suicide prevention effort in the long run. Conclusion: A community-based suicide prevention program was successfully implemented to address the suicide cluster. A reduction in the suicide rate was observed after the intervention.

A Pilot Study on the Efficacy of Volunteer Mentorship for Young Adults With Self-Harm Behaviors Using a Quasi-Experimental Design.

BACKGROUND: Studies have shown that postdischarge care for self-harm patients is effective in reducing repeated suicidal behaviors. Little is known about whether volunteer support can help reduce self-harm repetition and improve psychosocial well-being. AIM: This study investigated the efficacy of volunteer support in preventing repetition of self-harm. METHOD: This study used a quasi-experimental design by assigning self-harm patients admitted to the emergency departments to an intervention group with volunteer support and treatment as usual (TAU) for 9 months and to a control group of TAU. Outcome measures include repetition of self-harm, suicidal ideation, hopelessness, and level of depressive and anxiety symptoms. RESULTS: A total of 74 cases were recruited (38 participants; 36 controls). There were no significant differences in age, gender, and clinical condition between the two groups at the baseline. The intervention group showed significant improvements in hopelessness and depressive symptoms. However, the number of cases of suicide ideation and of repetition of self-harm episodes was similar for both groups at the postintervention period. CONCLUSION: Postdischarge care provided by volunteers showed significant improvement in hopelessness and depression. Volunteers have been commonly involved in suicide prevention services. Further research using rigorous methods is recommended for improving service quality in the long term.
