Quality of life in relation to mood, coping strategies, and dyskinesia in Parkinson's disease

J Geriatr Psychiatry Neurol. 2009 Jun;22(2):95-102. doi: 10.1177/0891988708328219. Epub 2009 Jan 15.


Given the variability of the results found in the literature, the current study is a step toward better clarifying the influence of motor and nonmotor factors on quality of life in Parkinson's disease. A total of 135 participants with Parkinson's disease were selected. Semistructured interviews were carried out, after which their mental and cognitive states were assessed using different scales (MINI, MADRS, EHD, HAMA). Finally, all participants completed 3 self-report questionnaires: 2 assessing coping strategies (WCC, CHIP) and 1, quality of life (Parkinson's disease questionnaire-39). It appears that the presence of dyskinesia, depression, and anxiety were linked to a poor quality of life. Interestingly, some different coping strategies, namely diversion as well as emotional strategies, were associated with a poor quality of life. These results encourage us to develop interventions focused on coping strategies and tailored to the emotional and clinical characteristics of each patient.
