To measure the experienced burden by informal carers (N=2.444), a 15-item Mokken scale has been developed. This concerns an extended version of the EDIZ (“Ervaren druk door Informele zorg”); several items refer to the pressure of time brought by the combination of labour and care and the consequences for the health of the informal carers are added to the EDIZ. We call this new scale the EDIZ-plus; it concerns a reliable one-dimensional and hierarchical scale which extends from 0 (no burden) to maximum 15 (severe burden).
