Introduction: The college students have high rates of suicidal ideation often associated with psychosocial factors. The aim of this study was to evaluate whether some of these psychosocial variables are related to the high prevalence of suicidal ideation in a College Spanish. Method: Participants (n = 40), aged between 21 and 34 years, Mean = 23.90 years and Standard Deviation = 3.003) were divided into two groups according to scores on the Inventory of Beck Suicide Ideation (SSI) (greater than 10 points) and, moreover, we applied various psychosocial measures. Results: The results showed that students more likely to have suicidal ideation are less optimistic, have poorer social skills and less social support. Conclusions: Early identification of psychosocial factors related to high ideation may help prevent dangerous situations in this collective suicide.
