Inactivity, poor diet, alcohol, and smoking during pregnancy are linked to maternal stress and distress. Mindfulness-based interventions can improve health behaviours and mental health. The purpose of the study was to develop and evaluate the feasibility of a mindfulness-based maternal behaviour change intervention. Materials and methods: The eight-week 'Mind the Bump' intervention integrated mindfulness training with behaviour change techniques. It aimed to improve mindfulness, mental health, and adherence to UK maternal health behaviour guidance. Acceptability, practicability, effectiveness/cost-effectiveness, affordability, safety/side-effects, and equity were evaluated from baseline to post-course and follow-up. Results: Mindfulness, positive affect, and wellbeing improved. Stress, negative affect, depression, anxiety, and adherence to guidance did not improve. The intervention was practicable and safe, but the other implementability criteria were not satisfied. Conclusion: The intervention was not fully feasible; recommendations to address its limitations are discussed. 收起
