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.

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.
Time frame: At baseline prior to intervention

Maternal postnatal depression
Maternal depression measured by the Edinburgh Postnatal Depression Scale. Possible scores range from 0 to 30. Higher scores indicate higher levels of depression.

Infant's developmental outcomes
Measured by the Cognitive Battery of the Merrill-Palmer-Revised Scales of Development, which includes assessments in the cognitive, receptive language, and fine motor domains. Higher scores denote better performance in the assessments
