Data was collected in five countries from informal carers of older people ( n = 577) via a common protocol. Carers completed: (1) a 17-item version of the Carers of Older People in Europe (COPE) Index, an assessment of carers' perceptions of their role : (2) a questionnaire on demographic and caregiving circumstances : and (3) three instruments included for the criterion validation of the COPE Index (the General Health Questionnaire, the Hospital Anxiety and Depression Scale, and the World Health Organization Quality of Life-BREF).
