A Comprehensive Approach to Suicide Prevention
Suicide Prevention Resource Center
"Effective suicide prevention is comprehensive: it requires a combination of efforts that work together to address different aspects of the problem.
The model above shows nine strategies that form a comprehensive approach to suicide prevention and mental health promotion. Each strategy is a broad goal that can be advanced through an array of possible activities (i.e., programs, policies, practices, and services). This model of a comprehensive approach was adapted from a model developed for campuses by SPRC and the Jed Foundation, drawing on the U.S. Air Force Suicide Prevention Program."
This article from SPRC.org lists several practices to consider when faced with a suicidal loved one.
