The impact of malignancy on death anxiety and psychological well-being in middle-aged and older patients undergoing abdominal surgery: a quasi-experimental study.

Background: Malignancy is a critical factor affecting death anxiety and psychological well-being. This study examined the impact of malignancy on death anxiety and psychological well-being in middle-aged and older adult patients undergoing abdominal surgery and projected it along with sociodemographic profiles.

Methods: This study is quasi-experimental in design. It was conducted with patients undergoing abdominal surgery at a university hospital due to suspected malignancy. A total of 93 patients participated in the study: 57 patients diagnosed with malignancy were included in the experimental group, while 36 patients without a malignancy diagnosis were included in the control group. Data were collected using a questionnaire developed by the researchers based on the literature, the 'Turkish Death Anxiety Scale', and the 'Psychological Well-being Scale'. The analyses revealed that the data were normally distributed, and parametric tests were used to analyze differences between demographic variables and groups. Cohen's d and r values were examined to assess the effect size in the tests.

Results: The study found a significant difference in death anxiety between the experimental and control groups (P < 0.05), with higher mean scores in the experimental group. Malignancy had a large effect on death anxiety (d = 1.42). Additionally, the control group had significantly higher mean psychological well-being scores compared to the experimental group (P < 0.05).

Conclusions: The study found that malignancy significantly affects death anxiety and psychological well-being. Increased death anxiety in patients with malignancy was associated with reduced psychological well-being. Thus, assessing death anxiety and providing targeted nursing care are essential for supporting the psychological well-being of these patients.
