美国心理协会最近做的一项调查发现人们对于心理疾病的知识、征兆、起因和有效的治疗方法方面的知识严重缺乏，如：抑郁症。几乎半数（44％）的人称，对此仅有一点了解或根本不知道。但是当问及是否认为多了解一些心理疾病的征兆是有益的时，84%的人回答：是日语口译。

A recent survey by the American Psychiatric Association (APA), conducted in observance of May as Mental Health Month, found a significant lack of consumer knowledge and understanding about the warning signs, causes, and effective treatments for mental illnesses, such as depression[2]. Almost half the public—44 percent—report knowing only a little or almost nothing at all about mental illnesses. But asked whether they would benefit from knowing more about the warning signs of mental illness, 84 percent said yes.
