The research literature indicates an association between the development of suicidal behaviours of young people and parental suicide behaviours. However, we lack empirical data on what children and adolescents know about their parent's suicidal behaviours and how they cope with the stress of living in a family where a parent has attempted suicide and may be at risk of attempting. We present the results of a qualitative exploratory study to understand what young adolescents know about the suicidality of a suicidal parent, what they thought and felt about it and how they coped with the situation. We conducted semi-structured interviews with eight adolescents between 12 and 15 years old living in a family where a parent had attempted suicide in the past 3 years, in order to obtain information on the perception of the adolescents themselves. In most cases we did not know if they knew or what they knew about their parent being suicidal. A significant number of the adolescents knew or suspected that their parent was suicidal. They used coping strategies like talking to their best friend or listening to music, but were inclined not to confide in adults and not to bring up the subject in the family. All the parents had contacted a community crisis centre for help, the adolescents were generally not offered any support . Support was generally only provided to the suicidal parent who contacted the crisis centre and to other adults involved in the intervention. Support should also be systematically offered proactively to the children and adolescents when their parent has suicidal behaviours in order to help them find efficient strategies to cope with the stresses associated with living with a suicidal parent. Specific approaches to helping children learn to cope better will be presented and discussed.
