Symptômes dépressifs et consommation problématique de substances psychoactives : effets modérateurs du contexte social
Of adolescents who use drugs, only a minority develops significant problems related to this drug use. It is then relevant to know and understand the processes by which this problematic consumption develops itself in order to be able to prevent it. This study examines the roles of depression symptoms and social relationships in the development of problematic drug use at the adolescence. More precisely, it aims at determining, with the help of a prospective correlational longitudinal design, if peers support, parental support and the quality of the teacher-student relationship have moderator effects on the relationship between depressive symptoms and problematic drug use. The sample used for this study is taken from the Stratégie d’Intervention Agir Autrement and is comprised of 4473 teenagers. Multiple linear regressions were completed and showed that depressive symptoms enhance the risk of a problematic drug use to be developed, whereas peers support impairs it. Contrary to what was expected, results show that parental support enhances the risk of developing a problematic drug use and that the teacher-student relationship has no significant impact. Moreover, peers support has a protective role, parental support intensifies the relationship between depressive symptoms and problematic drug use, whereas the quality of the teacher-student relationship attenuates it.
