The results suggested that the higher the ego integrity, the lower is the death anxiety
. Similarly, other researches on ego integrity and death anxiety

Some researchers have aimed to explain death anxiety
, and others have attempted to determine if any relationships exist between death anxiety
and different personality factors (Buzzanga, Miller, Perne, Sander, & Davis, 1989).
Clear and compelling reasons exist for the translation of the ASDA into the Farsi language and the study of its psychometric properties in order to investigate the cultural, ethnic, and sociodemographic factors that can influence the intensity of death anxiety
Over the years, there has been a considerable amount of psychological research focussed on death anxiety
Tools such as Templer's Death Anxiety
Scale(TDAS),  the Collett Lester Fear of Death Scale(CLFOD),  the Spanish Death Anxiety
Inventory(SDAI),  and the Arabic Scale of Death Anxiety(ASDA),  have been developed and demonstrate adequate reliability and validity.

Arabic Death Anxiety

Caregivers who experience death anxiety
have anxious thoughts or feelings when thinking about or talking about death and/or the dying process, or when interacting with someone who is dying (Lehto & Stein, 2009; Mallet, Jurs, Price, & Slenker, 1991; Tomer, 1994).
There were studies of death anxiety
in Iranian nurses for example [13-16], one study of reasons for fearing death using Reasons for Death Fear Scale (RDFS), one study of death concern and death obsession using Death Concerns Scale (DCS), and Death Obsession Scale (DOS) in Iranian nurses [17-18], but there has been no study using the Death Depression Scale (DDS) in Iran amongst nurses.
