Although a marked decrease is observed in recent years, suicide is the second cause of mortality for 15-19 year olds, and the first cause for 20-34 year olds. Juvenile offenders have a higher risk of suicidal behaviours, but risk factors in this population are not well studied. This paper presents the principal risk and protection factors associated with juvenile offender suicide risk by integrating them in an interactive model. Among the factors taken into account in the model are factors related to life events, individual factors (psychopathology, substance abuse, individual and personality characteristics), social factors (family, social network) and living factors (life environment and neighbourhood, school, residential facilities for young offenders). The case study of a teenage young offender – Olivier – is presented in order to support the interactive model.
