The aim of this study was to investigate the psychological risk factors of attempting suicide among college students. Psychological risk factors included were anxiety, somatoform, bipolar-disturbance, dysthymia, alcohol dependence, drug dependence, delusional disorder, major depression, and paranoid.This was an ex-post facto study which was done by questionnaire. 30 students who were attempting suicide and 30 students who did not attempt suicide were paired with each other based on their age, gender, marital status, field of study and academic year. These students completed MCMI-II questionnaire.Two groups of the subjects, i.e. attempted and non-attempted suicide, were significantly different in terms of symptomalogy of all the clinical disorders including anxiety, somatoform, bipolar-disturbance, dysthymia, alcohol dependence, drug dependence, delusional disorder, major depression, and paranoid. Psychological risk factors and mental disorders played an important part for those who were attempting suicide. Therefore by considering psychological status of students one can identify vulnerability people who are attempting suicide and prevent their attempt to suicide. In addition, by improving mental health of college students the risk of suicidal attempt can be reduced.
