Abstract

OBJECTIVE:

To investigate the relationship of resilience to disease severity, disability, quality of life (QoL) and non-motor symptoms in Parkinson's disease (PD). A secondary objective was to investigate whether resilience is distinct from other personality domains in PD.

BACKGROUND:

Resilience is the ability to reestablish emotional equilibrium in the face of adversity. It may play a pivotal role in disability and quality of life and has not been studied in PD.

METHODS:

83 PD patients (Age 66.3 ± 10.6, Total Unified Parkinson's Disease Rating Scale (T-UPDRS) 36.9 ± 17.8) completed the Resilience Scale 15 (RS-15). Scales measuring disability, mental and physical health-related QoL, non-motor symptoms (depression, anxiety, somatization, apathy, fatigue), and personality domains were completed. Pearson's correlations were analyzed between these scales and the RS-15.

RESULTS:

Greater resilience correlated with less disability (r = -.30, p = .01), and better physical and mental QoL (r = .31, p < .01; r = .29, p = .01), but not with PD severity (T-UPDRS, r = -.17, p > .05). Among non-motor symptoms and personality domains, resilience strongly correlated with less apathy (r = -.66), less depression (r = -.49), and more optimism (r = .54, all p < .001). Moderate correlations were seen between more resilience, reduced fatigue (r = -.40) and anxiety (r = -.34; both p < .001).

CONCLUSIONS:

Resilience correlated with less disability and better QoL but not with PD severity. Resilience was also highly associated with both non-motor symptoms (less apathy, depression, fatigue) and a personality domain (more optimism). The role of resilience in helping patients adapt to living with symptoms of chronic disease may explain its lack of correlation with PD severity.
