The CHILDSPLA project


The primary contribution of this research is to develop an interactive app for iPad, which uses animated characters as a new method to collect children’s views about their health. While there are several measures to estimate adults’ health state preferences, there are currently no measures to elicit the preferences of children themselves.

The underlying hypothesis is that health status information can be directly collected even from children as young as 4 years old by use of animated characters, in part because it will require lower language and literacy competencies than traditional methods.


We expect that the use of animated characters instead of written questions will yield a number of benefits:

  • A greater proportion of sick children will be able to indicate their current health status than can be achieved through self-completion of written questions.
  • A greater proportion of children in any particular age group will be able to report their current health state.
  • There may be advantages in terms of data collection and management.
  • It may be possible to elicit preferences over health states from many more children than would be feasible with current methods.
