To help settle this long-standing dispute, I studied why the number of recognized psychiatric disorders has ballooned so dramatically in recent decades. In 1980, the Diagnostic and Statistical Manual of Mental Disorders added 112 new mental disorders to its third edition ( DSM-III ).
为了帮助化解这一长期的争论，我对在过去几十年里被确认的精神疾病数量大幅增加的原因进行了研究。在1980年，《精神疾病诊断及统计手册》第三版( DSM-III )中新增了112种疾病。在其修订版(1987)和第四版(1994)中共又增加了58种。
