Death anxiety is defined as the level of anxiety one feels when thinking about death.
The instrument used in this research was self-report questionnaires. The research questionnaire consisted of three parts. The first subscale of the Collett-Lester Fear of Death Scale measures a person's fear of own death. The other three scales either measures one's fear of someone else's dying, someone else's death, or one's own dying. These three scales are outside the scope of this thesis research.
