Étudier l'incidence de la dépendance à l'alcool ou aux drogues chez les étudiants exposés à la fusillade du Collège Dawson dans les 18 mois suivant celle-ci, identifier les précurseurs du développement d'une dépendance à une substance psychoactive en tenant compte de la sévérité d'exposition à l'événement, et examiner si la consommation d'alcool 18 mois après les événements est en lien avec les différents groupes de symptômes d'état de stress post-traumatique (ESPT).
Méthode:
La population à l'étude est composée de l'ensemble des étudiants du Collège Dawson au moment de l'événement. Les analyses ont été faites auprès de 854 étudiants inscrits au Collège au moment de la fusillade.
Résultats:
Cinq pour cent des femmes et 7% des hommes présentent pour la première fois de leur vie un problème de dépendance à une substance suite à la fusillade. Pour les hommes, leur jeune âge, la présence de pensées suicidaires au cours de leur vie, ainsi que le fait d'avoir vu le tireur au moment de la fusillade sont les principaux précurseurs de cas incidents de dépendance. Aucun des précurseurs étudiés n'est significatif pour les femmes. Les hommes et les femmes se distinguent également quant aux symptômes d'ESPT qui prédisent la consommation d'alcool 18 mois après la fusillade.
Conclusion:
La principale retombée de l'étude est de souligner l'importance de considérer le sexe des individus pour étudier leur consommation de substances psychoactives suite à un traumatisme.
