Lifetime suicide attempt was assessed by the question as "Have you ever tried to kill yourself or have you ever attempt suicide?" Polysubstance use was assessed by the question "How many drug do you use? Results: To find the predictive variable of suicide attempts logistic regression analysis was conducted. The analysis indicate that the best predictors of suicide attempt was having friends with substance use behavior in childhood of adolescent period, having substance users in family members, polysubstance use and aggression; but there was no a significant interaction between polysubstance use and aggression on suicide attempt.
