The tendency to suicide can be contagious character, especially if we are talking about teenagers aged 12 or 13 years. Those students, one of whom committed suicide, more often begin to think about suicide, or repeat the act of a classmate. The study, conducted by canadian scientists found that this effect persists for 2 or more years, and it is necessary to take into account both parents and school teachers and psychologists.
Staff conducted an analysis of statistical data, which were obtained during a large-scale national survey, which lasted almost ten years, in the period from 1998 to the year 2007. All data was analyzed 22 064 adolescents aged 12-17 years. The obtained results have established that the suicide of a classmate leads to increased risk of suicide among children and adolescents of all ages, but especially it affects the age group of 12-13 years, which, after the tragedy, the frequency of suicidal ideation increases by 5 times.
The older becomes a teenager, the more reduced the frequency of his thoughts about suicide: 14-15 suicidal thoughts became more 3 times and adolescents aged 16-17 years - only 2 times. The authors claim that after the tragedy, the circle of those in need of psychological assistance should be expanded, and it should include not only those who was a close friend of the deceased, but those who learned about suicide.
