EPDS
depression
The Chinese version of the EPDS is the most commonly used assessment tool for screening postpartum depression in China, with Cronbach’s α of 0.76 and a validity of 0.93. The scale has a total of 10 items, and each item is evaluated based on the severity of symptoms using a four-level scoring system (0 to 4 points). The presence of a total score ≥ 13 points indicates varying degrees of postpartum depression. Furthermore, a higher score corresponds to a more severe level of depression.
