Distress in Parkinson's disease: contributions of disease factors and metacognitive style

Abstract

Research has suggested that the high levels of depression and anxiety observed in Parkinson's disease are a primary consequence of its pathophysiology. This study aimed to test the hypothesis that a psychological factor, metacognitive style, is significantly associated with distress, independent of previously identified disease-related risk factors. Distress, metacognitive style and disease factors were assessed in 44 people with a diagnosis of Parkinson's disease. People with a specific metacognitive style had an increased vulnerability to distress over and above previously identified disease factors; this suggests future directions for the development of psychological interventions.
