The prediction of stress in carers: The role of behaviour, reported self care and dementia in patients with idiopathic Parkinson's disease

Stress scores were elicited from relatives living with Parkinsonian patients and correlated with various aspects of the patients' impairment. The (usually female) relatives looking after male patients reported higher levels of stress than husbands looking after their wives. In general, the best predictor of relatives' stress was the behavioural rating scale of the CAPE and a reported selfcare scale designed for the study. The relative contribution of Parkinsonian motor impairment and cognitive impairment to relatives' stress scores was examined. While motor impairment was still associated with relatives' stress after controlling for sex and cognitive deterioration, both dementia and cognitive impairment measured by the Mini‐Mental State Examination were not associated with relatives' stress if Parkinsonian disability was controlled for.
