In Hong Kong, student suicides have been a key concern in recent years. Suicidal behaviours among young students are often complicated involving multiple contributing factors and causal pathways. No single stressor could be enough to explain a suicide. Ironically, emotional distress and relational problems often act interactively, on the one hand, as risk factors to increase an individual’s vulnerability to suicidal behaviour, and, on the other hand, as protective factors to increase one’s resilience and connectedness, thus also help in suicidal prevention. In Hong Kong, we now have “one school with two social workers scheme” in secondary schools. School social work service has also been extended to primary and pre-primary schools. When school setting becomes one of the important contexts in social work practice, social workers should be well-equipped with knowledge, skills, and practice competence in understanding and handling emotions and relations of young students.
