10-item questionnaire - Score interpretation:

Score Interpretation
0-9 Low risk
10-12 Moderate risk - monitor closely
13+ High risk - further evaluation needed
Any positive response to item 10 Immediate evaluation for self-harm

A score of 13 or above is the most commonly used cutoff for probable depression (Cox et al., 1987; ACOG recommends screening with a validated tool such as the EPDS).

Diagnostic Criteria (DSM-5)

  • Onset during pregnancy or within 4 weeks of delivery
  • Five or more symptoms for at least 2 weeks
