Feasibility of a Dutch post-discharge parenting intervention (TOP program) for moderate preterm born infants

Background and aim: Moderate preterm (MP) birth is associated with an increased risk of developmental problems. However, post-discharge support for this group is scarce. The aim of this study was to evaluate the feasibility of a post-discharge parenting program (TOP program) for MP infants. Three feasibility dimensions were evaluated (1) recruitment capability and compliance, (2) intervention acceptability, and (3) limited efficacy testing. 

Methods: A group of MP infants with a gestational age (GA) between 32^0/7‐34^6/7 weeks and their parents received six home visits by a TOP interventionist until 6 months corrected age (CA). A pre-posttest intervention design with quantitative and qualitative measures was used. Recruitment capability and compliance, acceptability, and satisfaction with the intervention were evaluated using a questionnaire, checklists, interviews, and a focus group. Infant socio-emotional development, parental distress, self-efficacy, and reflective functioning were measured with questionnaires. Observation measurements were used for infant motor development and parental sensitivity. 

Results: Thirty-two families completed the six home visits. The satisfaction rate (scale 0–10) was remarkably high (Mean 9.4, range: 8–10). Parents reported that the program was suitable, enhanced their understanding of their infants' developmental needs, and increased their self-efficacy. The infants showed age-appropriate motor and socio-emotional development post-intervention. Parental self-efficacy, reflective functioning, and sensitivity improved from pre to post intervention, with small to large effect sizes. 

Conclusion: The study demonstrated high compliance, acceptability, and satisfaction with the TOP program for MP infants with promising infant and parent outcomes. This study contributes to the preparatory work prior to a larger scale evaluation and dissemination.
