Purpose: The aim of the current study was to investigate the psychopathological symptoms, psycho-emotional state, dream anxiety, and insomnia in healthy, mild and severe preeclamptic postpartum women and their relation to the severity of preeclampsia (PE).Materials and methods: This observational study included 45 healthy, 41 mild preeclamptic and 44 severe preeclamptic postpartum women. The 90-item Symptom Checklist Revised, Hospital Anxiety and Depression Scale, Insomnia Severity Index, and Van Dream Anxiety Scale (VDAS) were used to evaluate the psychopathological symptoms, psycho-emotional state, insomnia, and dream anxiety of the participants after delivery.Results: Severe preeclamptic women had higher VDAS scores than mild preeclamptic and healthy postpartum women (p: 0.001). The psychopathological symptoms were more frequent in preeclamptic women than in healthy controls (p: 0.001). Severe preeclamptic women had the highest scores in Hospital Anxiety-Depression Scale and Insomnia Severity Index (p: 0.001, p: 0.001, respectively).Conclusion: Preeclampsia negatively affects the psycho-emotional state, psychopathological symptoms and sleep patterns. Further, disturbed dreaming was more frequent in PE and also, all of these conditions became worse with the severity of PE. We speculated that the obstetricians should offer their preeclamptic patients an appropriate mental health care at bedside and postpartum period as needed.
