This article offers a preliminary analysis of psychiatric treatment during the Chinese Cultural Revolution on the basis of interviews and rare case records obtained from 'F Hospital' in southern China. In contrast to the prevailing view of psychiatry during this time, which highlights either rampant patient abuse or revolutionary ideology, we show that psychiatric treatment at this facility was not radically altered by the politics of the Maoist period. Instead, treatments were informed by a predominantly biomedical understanding of mental illness, one that derived from the prior training of the facility's lead physicians. Although political education was nominally incorporated into patient rehabilitation and outpatient care, it was not a constitutive element of inpatient treatment during the acute phase of illness.
