Relationship Between Posttraumatic Stress Disorder, Death Anxiety, and Insomnia in Adults After the Earthquake

Abstract

This study aimed to determine the relationship between posttraumatic stress disorder, death anxiety, and insomnia in adults after the earthquake. This study, designed in a relational-cross-sectional-descriptive model, was conducted with 624 adult individuals living in a province affected by the earthquake that occurred in Turkey on February 6, 2023. The study data were collected using a personal information form, Posttraumatic Stress Disorder Checklist, Turkish Death Anxiety Scale, and Bergen Insomnia Scale. The analysis of the study data was performed by using SPSS 25.0, AMOS 24.0, and G*Power 3.1 Statistical package software. A significant positive correlation was found between posttraumatic stress disorder and Insomnia and Death Anxiety (p < .05). There was a significant positive correlation between Death Anxiety and Insomnia (p < .05). It was determined that Death Anxiety has a mediating role in the impact of posttraumatic stress disorder on insomnia (95% Confidence Interval: 0.572/1.407) (p < .05). It was determined that the model created in line with the hypotheses was compatible and the model fit indices were within the desired limits, with x(2)/df = 1.795, RMSEA = 0.03, CFI = 0.95, GFI = 0.946, AGFI = 0.93, IFI = 0.95. It was determined that posttraumatic stress disorder increased death anxiety and insomnia after the earthquake. Conducting longitudinal studies on the post-earthquake period is recommended.
