Objective:
To investigate predictors of change in the sense of competence of primary caregivers and continuity in home care for dementia patients.
Design:
A prospective longitudinal study with a follow-up period of 10 months.
Setting:
Dementia patients living in the community selected by Dutch general practitioners.
Subjects:
Pairs of demented patients and their primary caregivers (N = 138).
Main Outcome Measures:
Sense of competence: a 27-item scale (alpha = 0.79) based on issues derived from the family crisis model and the Burden Interview. Continuity in home care is determined by the number of patient's admissions to a nursing or retirement home.
Results:
Regression analysis revealed that a change in the caregiver's sense of competence was independently predicted by characteristics of the patient, the primary caregiver and the professional social network. A decreased sense of competence was associated with a longer duration of dementia and the patient's more agitated behaviour, the caregiver's higher initial sense of competence and being a female caregiver sharing a household with the demented patient. A positive influence on the change in the sense of competence was found when these females received a professional intervention consisting of support for the caregiver. Reporting to be a Catholic or a Protestant compared with not being religiously involved positively influenced the change in sense of competence. Logistic regression analysis identified that continuity in home care was predicted by characteristics of the demented patient and the professional social network of the patient. Predictors of continuation of home care were: lower severity of dementia, patient's higher ADL impairment, the intervention and involvement of regular home help. Institutionalization was more likely when the patient's behaviour was more apathetic and a district nurse was involved in the care.
Conclusions:
Caregiver characteristics influenced the change in sense of competence but did not influence the risk for institutionalization. Findings suggest that health professionals should pay attention to the negative consequences of agitated behaviour and to the most vulnerable group, females sharing a household with the demented patient.
