The main aim of this study is to examine the elderly in terms of some psychological phenomena and help them live better in this period of life. The method was based on descriptions of a non-experimental causal-comparative method. The statistical population consisted of elderly men and women over 65 years of age living in Khorramabad city in 1401. Based on systematic random sampling, given the availability of their names in the Sib system of Lorestan University of Medical Sciences, 200 elderly people were systematically selected from the list of characteristics over a period of nearly two months and, after determining a specific time to administer the tool, they responded in person to the perceived social support and death anxiety questionnaires. The results of multivariate analysis of variance indicate that a difference in social support and death anxiety was observed in the gender variable.The comparison shows that men tend to have social support and elderly men show higher scores in terms of death anxiety. Also, there was a difference between them in terms of marital status. Their comparison showed that elderly people who have a spouse tend to have more of this support. Regarding the interaction of the three variables of gender, marriage, and social class, evidence for death anxiety indicates the existence of an interaction between these three variables, while no interaction was observed for the variable of perceived social support.
