In 2013, the National Alliance for Mental Illness New Hampshire (NAMI NH) was awarded the Garrett Lee Smith (GLS) grant to develop and implement grassroots suicide prevention initiatives in key regions of the State housing high proportions of at-risk youth. I investigated the effectiveness of this work by gathering stories of significant change from key grant affiliates who implemented the interventions and then verifying and enriching those stories with others who had experienced them. Below, I describe the need for suicide prevention interventions in NH youth—both at the time the grant was awarded, as well as at present. I outline the Most Significant Change (MSC) method used to examine the interventions’ effectiveness through the gathering of change stories and describe the application of this method and the consequent data analysis. Finally, I present the results through revised change stories and explore the implications of these results with respect to NH youth and national suicide prevention initiatives.
