Abstract
Background Existential anxiety is a significant concern for patients with life-threatening illnesses like brain tumors. This study explores the prevalence and impact of existential anxiety among brain tumor patients in Saudi Arabia, examining relationships between demographic, clinical, and psychological variables and death anxiety. Methods A cross-sectional study was conducted with 120 brain tumor patients from inpatient and outpatient settings at King Abdulaziz University Hospital, King Fahad Hospital, and King Abdullah Medical Complex in Saudi Arabia. Data were collected using the Death Anxiety Scale (DAS), Spiritual Well-Being Scale (SWBS), Meaning in Life Questionnaire (MLQ), and the 12-item Short Form Survey (SF-12). Descriptive and inferential statistics analyzed the relationships between variables. Results Females exhibited significantly higher DAS scores (77.9 ± 14.2) compared to males (48.5 ± 19.4) (p < 0.001). Educational attainment was inversely related to DAS, with illiterate patients scoring highest (83 ± 13.5) and those with higher education scoring lowest (47.3 ± 18.2) (p < 0.001). Widowed patients had higher anxiety (68.5 ± 22.1) compared to married (51.4 ± 21.5) and single patients (50 ± 12) (p < 0.001). Monthly income showed an inverse relationship with DAS. Patients with chronic medical conditions reported lower DAS scores compared to those without (p = 0.004). The tumor stage significantly influenced DAS, with third-stage patients showing lower anxiety than those in the first and second stages (p < 0.001). Longer duration since diagnosis was associated with lower DAS scores (p = 0.03). Conclusion This study highlights the significant psychosocial impact of brain tumors on Saudi Arabian patients, emphasizing the need to address demographic factors in managing death anxiety. Findings indicate that chronic medical conditions and advanced tumor stages might be associated with lower anxiety, revealing potential resilience factors. The positive influence of spiritual well-being and meaning in life on quality of life underscores the importance of holistic care approaches. Integrating psychological and spiritual support tailored to individual patient demographics could enhance management strategies and improve patient outcomes. Future research should explore longitudinal changes in existential anxiety, the role of cultural factors, and the effectiveness of holistic interventions in reducing anxiety and improving quality of life.
