This study evaluated the effectiveness of a culturally adapted version of the Mother-Infant Transaction Program (MITP) among Chinese mothers with premature infants in public hospitals in Hong Kong.
Potential participants at two public hospitals in Hong Kong were identified by ward nurses. Mother-infant dyads with infants born at 36 weeks or earlier were assessed for eligibility. Data collection was conducted after obtaining written consent from the mothers. Mother-infant dyads who met the inclusion criteria were randomly allocated to either the intervention or the treatment-as-usual control group. Each dyad was assessed at six time points, i.e., baseline, immediately after intervention/TAU, and when the infants were at the gestation-corrected ages of 3, 6, 9, and 12 months.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Mother-Infant Transaction Program | Experimental | Four sessions were delivered to the mothers one-on-one based on a manualized protocol while the infants were still in the neonatal intensive care units. These coaching sessions included psychological care for the mother and topics on recognizing premature infant's characteristics, understanding and recognizing signs of infant stress and infant's engagement and disengagement cues, principles of graded stimulation, and how to optimize interactions and avoid over-stimulating the infant. |
|
| Treatment as usual | Active Comparator | For this group, infants and mothers received standard hospital care following the initial baseline assessment; these mothers were invited to ask questions about recommended ways to take care of their infants, but no specific knowledge or skills targeted by the adapted MITP program were taught |

| Behavioral observation of mother-infant interactions | Maternal sensitivity and quality of mother-infant interaction measured by coding a 5-min video of mother-infant interaction. The coded variables are rated on a 5-point scale, and higher scores indicate higher maternal sensitivity and better interaction quality. | At baseline prior to intervention |
