To assess whether willingness to disclose experience of a mental disorder and treatment, and awareness of others’ experiences have changed over a 16-year period.

In 2011, telephone interviews were carried out with 6019 Australians aged 15+. The survey interview used the same questions as those of the 1995 and 2003/4 national mental health literacy surveys, in which participants were presented with a case vignette describing either depression, depression with suicidal thoughts (2003/4 only), early schizophrenia or chronic schizophrenia (2003/4 only). Participants were asked whether they had a close friend or family member who had experienced a problem similar to that described in the vignette and whether the person received professional help. They were also asked whether they had experienced such a problem and whether they received professional help.

The numbers of those disclosing experiences of depression and early schizophrenia, and of having received professional help for depression, have increased since 1995. Awareness of a family member or close friend with experiences of depression and early schizophrenia also increased between these years, as did awareness that the person received professional help.

The numbers of those disclosing experiences of and treatment for mental disorders has increased in the last 16 years. This is likely to be due to increased willingness to disclose rather than increased prevalence of disorders or increased rates of help-seeking.
