Abstract

Objective: To assess the prevalence of bipolar I and II disorders in an Australian population.

Method: The Mood Disorder Questionnaire (MDQ) was administered to 3015 respondents in a random and representative sample in South Australia. Health status, quality of life and demographic data were also collected.

Results: There was a 2.5% lifetime prevalence of bipolar I and II disorders delineated by the MDQ. Those people had a significantly greater use of services and a poorer health status and quality of life than those who were MDQ-negative.

Conclusions: These results in an Australian population are consistent with other international studies showing a greater prevalence of bipolar disorders than hitherto appreciated.
