Introduction: The aim of this study was investigating the relation between impulsivity, in attention/ hyperactivity, and Traumatic life events with hoarding symptoms disorder in university students.

Methods: Study method of this research is descriptive-correlational. The sample size of this study was 219 students who were selected in a stratified random sampling method from different faculties of Payam Noor University, Hamedan Branch. The instruments used in this study were Life Events Checklist (LEC), Barratt Impulsivity Scale(BIS), Saving Inventory-Revised(SIR) and attention deficit-hyperactivity disorder Symptom Scale(ADHDSS). Data were analyzed by Pearson correlation coefficient and multivariate regression analysis.

Results: The results showed that there is significant relationship between hyperactivity /inattention symptoms with hoarding symptoms (r = 0.54 p <0.001), impulsivity with hoarding symptoms (r = 0.31, p <0.001), and between Traumatic life events and hoarding symptoms (r = 0.162, p <0.05, and these variables are able to explain 0.29% of the variance in the syndrome of hoarding disorder.

Conclusion: According to this study, it can be concluded that high ADHD, impulsivity, and Traumatic life events are associated with a significant increase in hoarding syndrome.
