Hi Catherine
We have used the WEMBS the Warwick Edinburgh Mental Well Being Scale a validated tool developed by Sarah Stewart Brown. Quick and simple to use and can be used by HVs to at the start of an intervention or piece of work and then at the end to show if parental well being has improved. See herehttp://www2.warwick.ac.uk/fac/med/research/platform/wemwbs/ Health Scotland use it and it can be self administered it is on the NHS Choices website see herehttp://www.nhs.uk/Tools/Documents/Wellbeing%20self-assessment.htm. We use it at Family Links before and after a parenting course and it shows a definite shift. I have also use when working with parents on sleep issues. Very useful for commissioners to see evidence of outcome from health visiting input.
