Are family caregivers willing to pay for support interventions?

[...]the measurement of willingness to pay is problematic; respondents are asked about a relatively broad intervention that may or may not have been perceived as being linked to the intervention they just experienced. First and foremost, one would want to know whether willingness to pay is associated with benefits derived from the intervention. In this small sample study (n < 100) recruited from five countries in Europe, the majority of family caregivers (81% on average) were willing to pay for the devices, although the maximum amount they were willing to pay was in most cases below actual cost of the technology (Duff and Dolphin, 2007).
