Purpose
This study was done to examine whether depression, self-esteem, and social support influence suicidal ideation among college students.
Methods
Using a correlation study design, participants were recruited from two universities selected by convenience sampling. Data were collected from June 1, to August 31, 2014 from the 206 participants included in the study. The data were analyzed using SPSS/WIN 18.0.
Results
There was a significant correlation between depression, self esteem, social support, and suicidal ideation. Suicidal ideation was negatively correlated with self-esteem (r=-.64, p<.001) and social support (r=-.45, p<.001), while, suicidal ideation showed a positive correlation with depression (r=.69, p<.001). The significant predictors related to suicidal ideation were depression, self-esteem, and social support.
Conclusion
Findings indicate that sensitively assessing depression in college students and efforts to reduce depression can reduce the risk of suicide. Self-esteem and social support of college students are also important resources for suicide prevention.
