title: Measuring the economic costs of discrimination experienced by people with mental health problems: development of the Costs of Discrimination Assessment (CODA).
abstract: OBJECTIVE
  Stigma and discrimination are faced by many with mental health problems and this may affect the uptake of services and engagement in leisure and recreational activities. The aims of this study were to develop a schedule to measure the impact of stigma and discrimination on service use, employment and leisure activities and to estimate the value of such reductions.
  
  
  METHODS
  A questionnaire, the Cost of Discrimination Assessment, was developed and piloted in a sample people with mental health problems. Costs were calculated and test-retest reliability assessed.
  
  
  RESULTS
  Test-retest reliability was good for most items. A substantial proportion of the sample had experienced negative impacts on employment as a result of stigma and discrimination. Around one-fifth had reduced contacts with general practitioners in the previous 6 months due to stigma and discrimination and the leisure activity most affected was visiting pubs/restaurants/café.
  
  
  CONCLUSIONS
  In conclusion, stigma and discrimination result in reduced use of services and reduced engagement in leisure activities. This represents a welfare loss to individuals.
