RemarksAll respondents that were not able to answer self-report questions because of severe cognitive decline were excluded from the sample. The publication reports an analysis using a ' happiness factor' consisting of 2 more measures which do not fit the criteria for inclusion in the WDH. Hence the results obtained with that measure are not included here.
