It is a 10-item self-report scale that measures maternal depressive symptoms over the past seven days. Higher scores reflect more depressive symptoms. Symptoms are rated on a 4-point Likert scale with scores ranging from 0 to 30. The cut-off score of the scale was determined as ≥13. If the total score of the scale is 12 or less, the participant is not at risk for PPD, but if he scores 13 or more, he is at risk.

The lowest score that can be obtained from the scale is 0 and the highest score is 24. As the score increases, attachment is negatively affected.
