“…These programs use one or more approaches, such as parent education, provision of psychological support, teaching developmental care, and facilitating better communication, to address a variety of domains including parent-infant interaction, parental knowledge and confidence, and parental stress. Most of the trials reported beneficial short and long-term infant and parent outcomes, including shorter hospital stay [55], better cognitive development [48,54,58,61], improved mother-infant interaction and attachment [49,56], reduced parenting stress [54][55][56], less maternal depression and anxiety [55,58], improved maternal confidence in parenting [55,58], better maternal sensitivity/ responsiveness [60], and higher maternal self-efficacy [61]. Two studies of a parent education program failed to find any effect on infant development, maternal stress/anxiety, or maternal-infant interaction [51,63].…”
