The Australian public's beliefs about the harmfulness of antipsychotics: associated factors and change over 16 years.

Negative views of psychiatric medications are common in many countries. Relatively little is known about beliefs about antipsychotic medications. A 2011 national survey of 2024 Australian adults assessed beliefs about their helpfulness or harmfulness for a person with either early or chronic schizophrenia and the associations with sociodemographic characteristics, exposure to schizophrenia, recognition of schizophrenia, and beliefs about other interventions, long-term outcomes, causes, and stigmatising attitudes. Changes since previous surveys (conducted in 1995 and 2003/4) were also assessed. Results showed that 19% of Australian adults believe that antipsychotics would be harmful for a person with early schizophrenia and 14% for chronic schizophrenia. This group was more likely to be male, born overseas, have less exposure to schizophrenia, show poorer schizophrenia recognition, have less positive views about other standard interventions, be less pessimistic about long-term outcomes and have greater stigmatising attitudes. Comparison with previous surveys showed that overall belief in the harmfulness of antipsychotics for schizophrenia decreased between 1995 and 2003/4 and between 1995 and 2011. The higher proportions of males and those from non-English speaking backgrounds believing in harmfulness suggest that education about the role of antipsychotics in the treatment of schizophrenia should focus on these groups.
