Parent-child interaction after home-visiting intervention for children born extremely preterm-A randomised clinical...

To determine whether a strength-based home-visiting program enhances parent-child interaction during the first year at home for children born extremely preterm (gestational age < 28).

A randomised controlled trial of 130 infants born extremely preterm 2018-2021 in Stockholm, allocated to either the Stockholm preterm interaction-based intervention (SPIBI) (n = 66) or an extended follow-up program (n = 64). The intervention group received ten home visits during the first year by a trained interventionist following SPIBI guidelines: an interaction-based intervention supporting sensitive parental responses to infants' signals. The primary outcome of emotional availability was assessed at 12 months corrected age (CA) using the emotional availability scales (EAS).

At 1-year CA, data were collected from 115/130 (89%) of the included children. There were no significant group differences in emotional availability at 12 months CA. A secondary analysis showed an effect modifier in families with mothers self-rated as depressed at discharge, with the outcome favouring intervention in the EAS dimension of child involvement.

The SPIBI had no significant main effect on emotional availability at 12 months CA. Children of self-reported depressed mothers displayed superior involvement behaviour in the intervention group, prompting further research on risk groups and potential modifications of post-discharge interventions.
