The transition of a pregnant woman's role often causes emotional changes that have an impact on marital satisfaction. We develop MIESRA mHealth and evaluate its impact on satisfaction of husband-wife relationship during pregnancy. A quasi-experimental study was conducted on 82 couples of pregnant women and divided into control, single, and paired group. We implemented MIESRA mHealth for four weeks. In the couple group, the wife did mindfulness based on the information in the MIESRA mHealth together with her husband. In a single group, the wife sees the video as an initial guide to doing mindfulness. In the control group, respondents received programme interventions from hospitals which included education and consultation with obstetricians. Husband-wife relationship is evaluated using Compatibility of Husband-and-Wife Relationships / Kesesuaian Hubungan Suami Istri (KHSI) questionnaire and the generalised estimating equations (GEE) was used to analyse the data. The women's KHSI scores in the couple and single intervention groups (β = -7.46, p = 0.002; β = -9.11, p = 0.001) were better than the control group. The husbands' KHSI scores in the paired and individual intervention groups (β = -7.04, p<0.001; β = -3.74, p = 0.024) were better than the control group. Nursing interventions to build emotional bonds between parents and foetuses based on mHealth can be a promising intervention for marital harmony during the perinatal period. MIESRA m-Health is a promising intervention on marital satisfaction during pregnancy and can be implemented as a part of the antenatal care programme to increase marital satisfaction.
