This study examined relationship of depression, life stress and personality with suicidal ideation among college students. Sample for the study consisted of 250 subjects (125 male & 125 female) drawn from different colleges of Haryana by using cluster sampling method. The objectives of the study were (a) to explore the association between suicidal ideation, depression, life stress and personality, and (b) to find out linear combination of different predictors of suicidal ideation. The participants were assessed with Scale for Suicide Ideation (SSI), Beck Depression Inventory (BDI), Eysenck Personality Questionnaire-R (EPQ-R) and Presumptive Stressful Life Events Scale (PSLES). The data were analyzed by using Pearson Product Moment method of correlation and stepwise multiple regression analysis. Results demonstrated that suicidal ideation was positively associated with depression, stressful life events and two dimensions of personality i.e. extraversion and psychoticism. Stepwise Multiple regression analysis found linear combination of three main predictors of suicidal ideation i.e. depression, extraversion, and stressful life events.
