D eath is one of the few guarantees of human existence, and yet is one of the greatest mysteries of life. The unknown aspect of death, combined with its inevitability and universality, results in some measure of death anxiety for much of humanity. Death anxiety, its various aspects, and the factors that contribute to and correlate with it have been the subject of numerous research studies over the past few decades, which have uncovered a number of consistent predictors of death anxiety, including age, gender, and self-esteem. The goal of the present study is to further investigate the impact of these variables on death anxiety and to uncover any interactions that may occur between them. Death Anxiety and Age According to Russac, Gatliff, Reece, and Spottswood (2007), death anxiety literature consistently demonstrates an age effect, which "refers to the fact that young adults often report higher levels of concern over mortality issues than older adults" (p. 549). In their own experiments investigating the relationship between death anxiety and age, using both the Collett-Lester Fear of Death Scale-Revised (CL-R; Lester, 1994, as cited in Russac et al.) and the Revised Death Anxiety Scale (RDAS; Thorson & Powell, 1994), Russac et al. found death anxiety to be highest in the 20's and lowest in old age (65+ years). In his unpublished dissertation investigating the demographic and socio-cultural variables impacting death anxiety, Scovel (1999) also found that older participants reported less fear of death than younger participants. Thorson and Powell (1994) found a negative linear relationship between age and death anxiety during the development of the RDAS, as an ANOVA revealed significant differences between young adults (18-20 years), adults (21-36 years), and the two older age groups combined (37-88 years). In a different study, Thorson and Powell (2000) found that age correlated negatively with death anxiety and depression and positively with religiosity; the young scored lower on the Intrinsic Religious Motivation scale (IRM; Hoge, 1972, as cited in Thorson & Powell, 2000) and higher on the RDAS than the old. Rasmussen and Brems (1996) tried to tease apart the distinction between age and psychosocial maturity in an attempt to better understand the age effects associated with death anxiety.
