The Effect of an Adapted Mindfulness-Based Stress Reduction Program on Mental Health, Maternal Bonding and Birth Outcomes in Psycho-socially Vulnerable Pregnant Women: a Randomized Controlled Trial.

Background A history of psychopathology or psychosocial adversities are risk factors for mental disorders in the perinatal period. Mental disorders in pregnancy can adversely affect the developing fetus, which call for early prevention. Mindfulness-Based-Stress-Reduction (MBSR) is an acceptable intervention for pregnant women and has a growing evidence-base with meta-analyses consistently pointing to reductions in symptoms of stress, anxiety and depression. The aim of this study is to address the need for a wider array of evidence-based and non-pharmacological options to improve mental health in a psychosocially highly vulnerable group of pregnant women.

Methods/design Pregnant women (n = 238) referred to an outpatient clinic at Copenhagen University Hospital, Amager and Hvidovre, Denmark will be recruited for the study. The design is a single-center, parallel group, randomized controlled trial, with an adapted MBSR program as add on to usual care. The primary outcome is mental wellbeing. Secondary and exploratory outcomes include stress, anxiety, depression, mindfulness, compassion, antenatal attachment and childbirth experience. Participants will be randomized in a 1:1 ratio to prenatal MBSR or usual care.

Implications for perinatal mental health Teaching the skills of mindfulness meditation to a psychosocially vulnerable group of pregnant women could prove a viable and non-pharmacological approach to improve mental health during pregnancy, reduce stress and support the transition to parenthood. The MBSR program does not target a particular group, and results from the study is thus of potential relevance for pregnant women in general as a means of reducing stress and improving perinatal mental health.
