Which of the following is a risk factor for postpartum psychosis?

The correct answer highlights that having a first pregnancy is a notable risk factor for postpartum psychosis. Research indicates that women who are experiencing their first pregnancy may face a greater likelihood of developing psychiatric disorders after childbirth, including postpartum psychosis. The psychological stress associated with the transition into motherhood for the first time can contribute to this increased vulnerability.

While a history of anxiety disorders can also raise the risk for postpartum mood disorders, it is not as specifically linked to postpartum psychosis as the factor of being a first-time mother. Additionally, having a healthy baby or strong family support generally serves as protective factors against developing postpartum mental health issues rather than risk factors. A supportive environment and a healthy outcome can help mitigate stress and resources, ultimately lowering the risk.
