The Yellow Ribbon Suicide Prevention Program has gained national and international recognition for its school- and community-based activities. After the introduction of Yellow Ribbon to a Denver-area high school, staff and adolescents were surveyed to determine if help-seeking behavior had increased. Using a prepost intervention design, staff at an experimental school and comparison school were surveyed about their experiences with student help-seeking. Additionally, 146 students at the experimental high school were surveyed. Staff did not report any increase in student help-seeking, and students' reports of help-seeking from 11 of 12 different types of helpers did not increase; the exception was help-seeking from a crisis hotline, which increased from 2.1% to 6.9%. Further research with larger, more inclusive samples is needed to determine whether Yellow Ribbon is effective in other locations. (Contains 4 tables.)
