The menu was developed using the WHO-CHOICE methodology to prepare and update, as appropriate, WHO estimates of the cost-effectiveness of a range of mental health interventions, in line with the development of Appendix 3 to the global action plan for the prevention and control of noncommunicable diseases 2013–2020. WHO-CHOICE is a programme that helps countries to identify priorities based on health impact and cost-effectiveness. It can be applied to a wide range of strategies relevant to policies affecting health outcomes. All options are compared to a common comparator, a null scenario in which the impacts of currently implemented interventions are removed, thereby enabling comparison of interventions across geographical areas and aspects of health.
