A small group with lived experience of mental health problems runs a consistent campaign in one town to reduce the stigma attached to schizophrenia. Researchers survey adults in that town and in a similar town with no campaign, once just before the campaign starts and again five years later, when the campaign ends.
The table shows the percentage of adults in each town who agreed that a person with schizophrenia is dangerous.
| Survey | Campaign town (%) | Town without the campaign (%) |
|---|---|---|
| Just before the campaign | 46 | 45 |
| Five years later | 34 | 37 |
