Background and Aim: The goal of current study is to assess the relationship between perceived social support, perceived burdensomeness and thwarted belongingness with suicidal behavior in college students.

Materials and Methods: The research design is descriptive in the form of correlation and prediction. The research sample included 295 college students whom studying in University of Mohaghegh Ardabili, which selected by convenience sampling. The participants completed materials of the Interpersonal Needs Questionnaire (INQ), Suicidal Behavior Questionnaire-Revised and perceived social support inventory. Research data were analyzed by descriptive statistics’ indices, Pearson correlation analysis, separation coefficient, and multi-variant regression by using SPSS.

Results: The obtained results suggest that there is a significant relationship between interpersonal needs, especially perceived burdensomeness with suicidal behavior in college students. Also, there is a significant relationship between perceived social support, especially perceived social support from family and friends with suicidal behavior and interpersonal needs, but by controlling interpersonal needs via partial correlation the relationship between perceived social support and suicidal behavior disappeared. Moreover, by controlling perceived social support the relationship between interpersonal needs and suicidal behavior was significant again, which from this construct perceived burdensomeness could explain and predict suicidal behavior better than thwarted belongingness.
