While many people accept that mental health problems can be effectively treated, prejudice and stigma towards those affected still strongly exists, a new worldwide study has found.

US researchers set out to learn more about the prejudice surrounding mental illnesses. They analysed data from a study which involved almost 20,000 people from 16 different countries worldwide. During that study, people were asked about their attitudes to three conditions - depression, schizophrenia and asthma.

The 16 countries were considered geographically, politically and developmentally diverse.

The researchers from Indiana University identified what they termed a ‘backbone' of stigma. This meant that even in countries where people tended to be more accepting of mental illnesses, stigma was still present. This stigma was particularly strong when it came to people with schizophrenia.

As a result of this ‘backbone' of stigma, those with mental illnesses were seen as people who should not be in positions of authority. They were also seen as people whom others should not have close personal relationships with.

"If the public understands that mental illnesses are medical problems, but still reject individuals with mental illness, then educational campaigns directed toward ensuring inclusion become more salient," the researchers insisted.

They noted that stigma can lead to discrimination in areas such as employment and healthcare and can have a long-term effect on the quality of life of those affected.

"The stereotype of all people with mental illness as 'not able' is just wrong. No data supports this. With the prevalence of mental health problems being so high, no individuals or families will go untouched by these issues. They need to understand that recovery is not only possible but has been documented," they said.

They added that these results challenge policymakers to ‘reconsider efforts to improve population mental health. Efforts should prioritise inclusion and integration'.

Details of these findings are published in the American Journal of Public Health.
