The Care-Related Quality of Life (CarerQoL-7D) instrument assesses carer quality of life in terms of burden and happiness (Visual Analog Scale [VAS]). For the 7D, carers choose from 3 responses to 7 different questions, their overall score aggregating to a total out of 100, with 100 representing the least carer burden. For the VAS, carers rate their happiness on a visual analog scale from 0 to 10, with 10 representing the greatest happiness.
