Family Conflict and Suicidal Behaviour in Adolescence: The Mediating Role of the Assertive Interpersonal Schema

Suicidal behaviour in adolescents is a significant problem worldwide. Family plays an important role in this issue, with family conflict associated with a greater likelihood of current suicidal ideation and suicide attempts. It has been suggested that the relationship between these two variables may be mediated by how social information is handled. The assertive interpersonal schema, which helps to understand conflict as a normal experience, may be a relevant variable. The aim of this study was to examine the direct and indirect effects of family conflict on suicidal behaviour through the assertive interpersonal schema in an adolescent sample. The sample comprised 229 participants (52.8% boys, M(SD)age = 15.76 years (1.24)). A total of 29.7% of the participants reported suicidal ideation, and 4.8% indicated having attempted suicide in the previous two weeks. Family conflict was positively related to suicidal ideation and suicide attempts. A multiple mediation analysis showed that both effects were significant in all the dependent variables, with the assertive interpersonal schema explaining a large part of the effect of family conflict, particularly for suicidal ideation. These findings have implications for the prevention and treatment of this problem in adolescents.
