This study analyzed data from the 1995 National College Health Risk Behavio
r Survey (NCHRBS) to assess the prevalence of suicidal ideation among colle
ge students in the United States and to examine the association between sui
cidal ideation and substance use in this population. The NCHRBS used a mail
questionnaire to assess health-risk behaviors in a nationally representati
ve sample of undergraduate students. During the 12 months preceding the sur
vey, 10% of the students had seriously considered attempting suicide. When
controlling for demographic characteristics, the analysis showed that stude
nts who had considered suicide were at increased odds of using tobacco, alc
ohol, and illegal drugs. These results suggest that colleges and universiti
es should establish suicide prevention programs that also address the relat
ed problem of substance use.
