When does benign become , a treatable disorder?

The authors pinpoint the fine line between overdiagnosis and underdiagnosis of SAD

ince the appearance of social (SAD) in the DSM-III in 1980, research on its prevalence, charac- Steristics, and treatment have grown (Box 1, page 221,2). In addition to the name, the definition of SAD has changed over the years; as a result, its prevalence has increased in recent cohort studies. This has led to debate over whether the experience of shyness is being over-pathologized, or whether SAD has been underdiagnosed in earlier decades. Those who argue that shyness is being over-pathologized note that it is a normal experience that has evolution- ary functions (eg, preventing engagement in harmful social relationships3). Others argue that a high degree of shyness is not beneficial in terms of evolution because it causes the © IMAGES.COM/CORBIS individual to be shunned, so to speak, by .4 Kristy L.
