Clinical and Research Implications
Despite these limitations, we used a relatively convenient and novel technology that allowed participants to easily access the intervention from WeChat on their smartphones or PCs. The digital GSH-MBI, which is accessible, convenient, inexpensive, and requires fewer professionals to operate, brings new prevention and intervention opportunities for mental health problems experienced by pregnant women, especially during the COVID-19 pandemic. We conducted the study in China, as WeChat is the most popular app among the Chinese population; however, our intervention package can be used in other apps. It is important to note that using existing widely used apps to deliver brief psychological interventions is more promising than developing new apps as intervention delivery platforms. In addition, the low dropout rates and high adherence to the intervention in this study support our viewpoint that easy access to information might increase participation and compliance with psychological interventions.The nonsignificant ripple effect of the digital GSH-MBI on infant outcomes at 6 months of age indicates that interventions need to be delivered in the postpartum period. However, our findings of the intervention’s ripple effect on infant temperament at 6 weeks of age are also encouraging. First, women tend to be more motivated to make healthy changes during pregnancy than at any other time in their lives [The authors thank all the participants for their time and effort.
