Abstract
Miscarriage is one of the most common complications in early pregnancy, occurring in approximately 25% of all pregnancies. It is well-established that women who experiencing miscarriage might suffer from stress, anxiety and depression. Randomised controlled trials (RCT) are a type of study in which a similar group of people are randomly divided into two or more groups to assess the benefits of specific drugs, treatments or other type of interventions. This review systematically looked at the published RCTs that compare the benefits of psychological and support interventions among pregnant women with a history of miscarriage. After screening a total of 4140 titles in the literature, we identified 17 RCTs. None of them met the criterion for participants to be pregnant during the study period, and therefore, this review was what some authors call an 鈥渆mpty鈥 systematic review. In 鈥渆mpty鈥 systematic reviews, the research question defined at the beginning of the study design cannot be answered and conclusions cannot be drawn. The finding of this review was unexpected given that there is a vast amount of evidence that states the need of assessing non-pharmacological interventions to reduce levels of stress, anxiety and depression among pregnant women with a history of miscarriage.
