Prediction of end-of-life fears in COPD – hoping for the best but preparing for the worst
Design: A total of 131 COPD patients participated at two time points. Regression and mediation analyses, as well as cross-lagged panel analyses were conducted.
Main outcome measures: The participants completed questionnaires assessing end-of-life fears (Multidimensional Orientation toward Dying and Death Inventory), psychological distress (Hospital Anxiety and Depression Scale), and disease-specific anxieties (COPD Anxiety Questionnaire). Pulmonary function and a 6-min walk test served as measures of illness severity.
Results: Illness severity was not predictive of end-of-life fears. However, gender and psychological distress explained incremental variance. When disease-specific anxieties were included as additional predictors, psychological distress was no longer significant. Cross-lagged panel analyses mostly supported these results. Moreover, disease-specific anxieties mediated the association between psychological distress and end-of-life fears.
Conclusion: Administration and intensity of end-of-life care (especially concerning end-of-life fears) in COPD patients should be based not only on illness severity, but rather on psychological distress and disease-specific anxieties.
