The objective of this study was to investigate whether depression and anxiety mediate the relationship between perceived stress and demoralization. The results showed that depression, anxiety, and subjective incompetence were mediators between perceived stress and demoralization, with subjective incompetence having the largest impact on demoralization.
ObjectivesThe objective of this study was to determine whether depression and anxiety are mediators between perceived stress and demoralization via a loss of the cognitive map to get out of the predicament manifesting as subjective incompetence. MethodsNinety-five consecutive outpatients with Parkinson's disease were evaluated for perceived stress, depression, anxiety, subjective incompetence, and demoralization using reliable and valid scales. Inclusion criteria were ages 40-90, intact cognition, and no current history of substance use. The setting was a Movement Disorders Clinic at a university-affiliated hospital. The outcome variable was demoralization, selected a priori. Mediators between perceived stress and demoralization were examined using path analysis. ResultsDepression, anxiety, and subjective incompetence were mediators between perceived stress and demoralization. Among all variables, subjective incompetence was the largest contributor to demoralization. Depression connected to demoralization indirectly via subjective incompetence (beta = 0.25, p < 0.001), whereas anxiety bypassed subjective incompetence (beta = -0.01, p = 0.882), connecting directly to demoralization (beta = 0.37, p = 0.008). ConclusionEarly treatment and reversal of subjective incompetence and anxiety could potentially prevent the escalation of demoralization and the associated disruption in health-related quality of life and eventual suicide.
