Abstract

Purpose. We aimed to address gaps identified in the evidence base and instruments available to measure the quality of life (QOL) of family carers of people with dementia, and develop a new brief, reliable, condition-specific instrument.

Results. C-DEMQOL was received positively by the carers. Factor analysis confirmed that C-DEMQOL sum scores are reliable in measuring overall QOL (omega = 0.97) and its five subdomains: ‘meeting personal needs’ (omega = 0.95); ‘carer wellbeing’ (omega = 0.91); ‘carer-patient relationship’ (omega = 0.82); ‘confidence in the future’ (omega = 0.90), and ‘feeling supported’ (omega = 0.85). The overall QOL and domain scores show the expected pattern of convergent and discriminant relationships with established measures of carer mental health, activities, and dementia severity and symptoms.

Conclusions. The robust psychometric properties support the use of C-DEMQOL in evaluation of overall and domain-specific carer QOL; replications in independent samples and studies of responsiveness would be of value.
