Purpose: The Carer Experience Scale (CES) is an index measure of the caring experience, focusing on six domains: activities outside caring, support from family and friends, assistance from the government and other organizations, fulfilment from caring, control over caring and getting on with the care recipient. This is an initial study of the construct validity of the CES focusing on validity in a heterogeneous group of carers in the UK.
Methods: The CES was included in a cross-sectional quality of life survey conducted in a UK city in 2010. The survey included a number of questions about the characteristics of the carer, care recipient, caring situation and motivation for caring. Hypotheses regarding the anticipated associations between these contextual variables and the caring experience were developed and statistically tested.
Results: Seven hundred and thirty carers fully completed the CES questionnaire. Associations between variables hypothesised to relate to the caring experience (such as recipient health and intensity of caring) and the CES were largely as expected, providing evidence that the CES captures the caring experience in a valid way. Most hypothesised associations were statistically significant in both carers of older and younger adults.
Conclusions: This study provides early encouraging evidence for the construct validity of the CES instrument. Further investigation is required to examine the validity of the CES in specific clinical subgroups and to examine the responsiveness of the CES in detecting changes in the carer's outcomes over time.
