What can a leave reform tell us about long-term support for mothers?

Uses a historical six-week leave extension to examine long-term psychiatric diagnoses, adding a stronger policy-design perspective while retaining the outcome’s clinical limits.

Study context

291,152 women giving birth in Denmark in 1981–1987, followed in national registers.

Age / stage: Adult mothers followed for up to 30 years.

Read with three questions

  1. How did the 1984 eligibility cutoff create the policy comparison?
  2. How large were the absolute differences in psychiatric diagnoses over time?
  3. Why does a first inpatient diagnosis miss many forms of distress and support?

Keep the limits in view

The design concerns a historical Danish reform and inpatient diagnoses; assumptions around the cutoff and transfer to today’s employers require scrutiny.
