| Annotation | Cognitive impairment and depression are common and disabling non-motor symptoms of Parkinson's disease (PD). Previous studies have shown associations between them but the nature of the relationship remains unclear. In chronic illness, problem- or task-oriented coping strategies are associated with better outcome, but often require higher level cognitive functioning. This study investigated the relationships between cognitive function, choice of coping strategies, and a broad index of outcome including depression, anxiety, and health-related quality of life (HRQoL). It was hypothesised that the coping strategy used could mediate the association between cognition and outcome. 347 patients with PD completed the Coping Inventory for Stressful Situations, the Hospital Anxiety and Depression Scale (HADS), the Parkinson's Disease Questionnaire-8, the Unified Parkinson's Disease Rating Scale, and the Addenbrooke's Cognitive Examination - Revised. Structural equation modelling was used to test the hypothesised model of cognition, coping, and outcome based on a direct association between cognition and outcome and an indirect association mediated by coping. Overall, poorer cognition predicted less use of task-oriented coping, which predicted worse outcome (a latent variable comprised of higher depression and anxiety and lower QoL). The analyses suggest a small indirect effect of cognition on outcome mediated by coping. (RH). |
