In 2006, following the shooting at Dawson College, the authorities implemented an intervention plan. This provided an opportunity to analyze the responses to services offered, and afforded a learning opportunity, which led to the proposal of an extensive multimodal short-and long-term

Both quantitative and qualitative data were gathered 18 months after the event, involving the participation of 948 students and staff. Mental health problems and the perception of services offered after the shooting were investigated, using standardized measures. Second, focus groups and individual interviews were conducted among a subgroup of participants (support team members; teachers and employees; students and parents) and permitted to gather data on services received and services required. Individual report of events, the extent of psychological impact and services offered and received were analyzed in terms of the following dimensions: intervention philosophy, training, ongoing offer of services and finally, detection and outreach. A significant incidence of disorders and a high rate of exacerbation of preexisting mental disorders were observed within the 18 months following the shooting. Postimmediate and short-term intervention appeared adequate, but the long-term collective vision toward community support and availability of mental health services were lacking. Lessons learned from this evaluation and other school shootings suggest that preparedness and long-term community responses are often overlooked. A multimodal extensive plan is proposed based on a theoretical model from which interventions strategies could be drawn.Keywords posttraumatic intervention; school shooting; trauma; PTSD; mental healthIn the last decade, the psychological intervention plans following disasters, including school emergency plans for a critical incident, have been developed at local, national, and international levels to offer support to survivors. The number of psychological first-aid programs is on the rise and targets specific disasters: disaster-related trauma; complex trauma; exposure to violence; traumatic loss; nonspecific mass trauma; organizational crisis management, and so forth (Jaycox et al., 2006;Hutchins & Wang, 2008 (Vernberg et al., 2008). In Quebec, the 1989 shooting of 22 young women at the Ăcole Polytechnique de MontrĂ©al prompted the development of a psychosocial approach to public security (Martel & Brunet, 2006).Despite the fact that each program has a different and specific emphasis, they share a common foundation: (1) they are based on theories of stress, coping, adaptation, and resilience after exposure to a traumatic event; (2) the programs are applicable and can be implemented in almost any environment (school, community, or other); (3) the programs are adapted to different types of clientele and the different developmental stages of life, even though there are specific indications for children, teenager...
