The purpose of this study was to examine the relationships between death anxiety and mental health in adolescents, with a focus on coping strategies for death anxiety. The result indicated that participants who do not cope at all with death anxiety have low death anxiety, but are in bad mental health. Moreover, it was indicated that participants who tried to be careful about their health and have a lifestyle in which every day was fulfilling showed lower scores for depression than those who frequently thought about death and talked about it with others. Furthermore, we found a significant positive collation between mental health and anxiety about dying with goals left unmet. We conclude that death anxiety has both negative and positive correlations with mental health, depending on coping strategies.
