This study aims to evaluate the effects of a 6-week mindfulness meditation program in pregnant women, compared with a psychological support control program.

Participants in the mindfulness arm will complete one instructor-led meditation session per week and five guided audio meditation sessions at home each week.

The primary objectives are to determine whether the mindfulness program leads to:

Reduced negative affect, including stress, anxiety, depression, and sleep disturbances during pregnancy.

Increased positive affect, such as mindfulness skills, self-efficacy, happiness, and life satisfaction.

Enhanced maternal-fetal attachment during pregnancy and improved maternal-infant attachment one month postpartum.

Improved mother-infant interaction quality at 3 months postpartum.

More secure infant attachment at 12 months.

Better infant outcomes, including reduced crying intensity/duration at 1 and 3 months, and improved sleep quality at 12 months.

Overall, the study evaluates whether the mindfulness program provides greater benefits than a standard parenting support intervention.

• Pregnant women between 3 and 7.5 months of gestation (12-28 weeks).
