ABSTRACT
BACKGROUND: Depression is a common problem in the Australian community. It results in considerable disability. Currently screening tools promoted for detection of depression are nonspecific. They are not diagnostic tools. While people identified by screening are, by definition, at higher risk of depression, the diagnosis still needs to be based on interview findings. Screening tools do not substitute for time spent with patients developing rapport and an understanding of the causes of the depression and formulating possible management steps. Screening alone has not been shown to improve outcomes for people with depression. OBJECTIVE: This article examines the current prevalence of depression in Australia and whether screening tools ultimately contribute to a reduction in morbidity. DISCUSSION: Screening instruments have arbitrary cut off points for identifying patients with depression and their findings regarding prevalence should be applied with caution. If the thresholds are low then 'prevalences' are raised. It is unclear whether all 'cases' detected using screening instruments require clinical intervention.
