The psychosocial burden on spouses of the elderly with stroke, dementia and Parkinson's disease

Objective To characterize the psychosocial burden on spouses living with the elderly suffering from mild dementia, stroke and Parkinson's disease, and to identify patient characteristics associated with it. Materials and methods Data on patient—spouse couples came from three studies of patients with stroke (36 couples), mild dementia (92 couples) and Parkinson's disease (58 couples). The psychosocial burden was recorded by the 15—item Relatives' Stress Scale (RSS). A factor analysis of this instrument produced a one‐factor solution (CFI = 0.98) consisting of eight items with good face validity and acceptable reliability within each diagnostic group (Cronbach's alpha range 0.66–0.69). Covariates of this factor were identified using structural equation modeling (SEM) by regression on patient's age, gender, cognitive function (MMSE), activities of daily living (ADL) and depressive symptoms (MADRS). Results Disorganization of household routines, difficulties with going away for holidays, restrictions on social life, and the disturbances of sleep were the most frequently reported problems in all three groups. According to the mean sumscore on the RSS, the perceived psychosocial burden was similar across the diagnostic groups. In the final SEM model, a lower cognitive function of the patient was associated with a higher psychosocial burden on the spouses of patients with stroke (β = −1.3, p = 0.01) and Parkinson's disease (β = −0.89, p
