Q44, on Page 21 of the 2015 B60 questionnaire, incorporated the CASP-19 measure of 50+ aged peoples' wellbeing as used in all waves of the English Longitudinal Study of Ageing (ELSA).  The 19 items in CASP are used to indicate the subjective wellbeing of individuals but, because ELSA has a sample of thousands of older people, it can provide an interesting comparator with the B60+ sample's responses.
