Analyzing the mediating Role of the Interpersonal Model of Suicide (perceived burdensomeness and thwarted belongingness) in relation between Mattering and Suicide

Suicidal behavior is a major problem worldwide and at the same time has received relatively little empirical attention. Interpersonal Psychological Theory believed that suicidalityy is caused by two risk factors of thwarted belongingness and perceived burdensomeness. The aim of this research was to Analyze the mediating Role of the Interpersonal Model of Suicide (perceived burdensomeness and thwarted belongingness) in relation between Mattering and Suicide in students. For this reason, through descriptive Research in the form of correlation and Structural Equation Model, 333 students of the University of Mohaghegh Ardabili selected by available sampling and Measured in regard to Interpersonal Needs, Mattering, and Suicidal Behavior. Correlation results showed that mattering has a direct correlation with interpersonal needs variable and also Suicide. Interpersonal needs have a direct correlation with Suicide. Indirect relations showed that mattering was correlated with suicide with mediating interpersonal needs. With regard to these findings, we can conclude that the joiner Interpersonal Theory of Suicide has a good fitness for predicting suicide, and Mattering variable can help us in predicting suicide within the scope of this theory and finally we can use it for preventing suicide.
