Effect of mindfulness group therapy on maternal psychological distress and perinatal outcomes in twin pregnancy: a randomized controlled trial.

An online mindfulness group therapy program for women with twin pregnancies prevented worsening of postpartum depression symptoms, improved mindfulness, and reduced perceived stress. The randomized controlled trial assigned 120 women to either six weekly 120-minute mindfulness sessions or usual care. Among the 109 who completed the intervention, those in the mindfulness group showed lower postpartum depressive symptoms and a lower incidence of low birth weight in their infants. The benefits held even when accounting for participants who did not finish the full study. The findings suggest that group mindfulness interventions integrated into prenatal care can help mitigate depression and stress in women expecting twins.

Abstract

Psychosocial stress, depression, and anxiety are prevalent during pregnancy and can be associated with adverse birth outcomes. This study aimed to evaluate the effectiveness of an online Mindfulness Group Therapy (MGT) program in improving perinatal maternal psychological distress and perinatal outcomes among women with twin pregnancies. In this randomized controlled trial, 120 women carrying twins were assigned to MGT groups (6-week, 120 minutes of mindfulness intervention weekly) or control groups (usual perinatal care and health education). The primary outcomes were maternal psychological distress, including depression, anxiety, stress, and mindfulness measured by the Edinburgh Postnatal Depression Scale, State Anxiety Inventory, Perceived Stress Scale, and Five Facet Mindfulness Questionnaire at three points: baseline, post-intervention and time one month postpartum. Secondary outcomes included maternal pregnancy outcomes and neonatal outcomes. A total of 109 women with twin pregnancies completed the intervention. The intervention significantly and effectively prevented the worsening of postpartum depression symptoms in women with twin pregnancies, improved mindfulness, and reduced perceived stress (P 0.05). Intention-to-treat analysis further revealed that the intervention had a significant effect on reducing postpartum depressive symptoms (P < 0.05), even when considering participants who did not complete the entire study process. In terms of pregnancy outcomes, a significant difference was found between the intervention and control groups in the incidence of low birth weight (P<0.05). MGT proves potentially effective in reducing perinatal stress, preventing prenatal depression, and decreasing the incidence of low-birth-weight infants in twin pregnancies. These findings support the integration of group mindfulness interventions into prenatal mental health care to mitigate prenatal depression among women expecting twins. https://www.chictr.org.cn/showproj.html?proj=131787, identifier ChiCTR2100050091.
