Measuring the benefits of health promotion programmes: application of the contingent valuation method.

Economic evaluation of health promotion programmes presents well documented challenges. These programmes often generate significant non-health benefits which are typically ignored within economic evaluation. This study explored the use of the contingent valuation (CV) method to value the broader benefits of a women's group programme to improve maternal and newborn health in Nepal. Interviews were conducted with 93 women's group members, 70 women non-members and 33 men. Respondents were asked to give reasons for their willingness-to-pay (WTP) in terms of health and/or non-health benefits. WTP was regressed against socio-economic and demographic variables using ordinary least squares. Seventy eight percent of respondents were willing-to-pay for the women's groups. There was no significant difference between the WTP of women's group members compared to female non-members. Men were willing-to-pay significantly more than women. WTP reflected non-health benefits in over 80% of cases. At least 11% of women attending meetings and 38% of those not attending were WTP for altruistic motives. Future research should address the relative value of non-health compared to health benefits; and motivations behind non-user values and their consistency across settings.
