This thesis focuses on topics such as preterm birth, variation in gross motor development, factors that influence (premature) infant gross motor development, and parental beliefs and practices. By gaining insight into these topics, this thesis aims to contribute to clinical decision-making of paediatric physiotherapists together with parents, and with that shape early intervention.
The TOP program is a fully implemented responsive parenting intervention for very preterm born infants. Fidelity monitoring of interventions is important for preserving program adherence, impact outcomes and to make evidence-based adaptations. The aim of this study was to develop a fidelity tool for the TOP program following an iterative and co-creative process and subsequently evaluate the reliability of the tool. Three consecutive phases were carried out. Phase I: Initial development and pilot testing two methods namely self-report and video based observation. Phase II: Adaptations and refinements. Phase III: Evaluation of the psychometric properties of the tool based on 20 intervention videos rated by three experts.The interrater reliability of the adherence and competence subscales was good (ICC.81 to .84) and varied from moderate to excellent for specific items (ICC between .51 and .98). The FITT displayed a high correlation (Spearman’s rho.79 to.82) between the subscales and total impression item. The co-creative and iterative process resulted in a clinical useful and reliable tool for evaluating fidelity in the TOP program. This study offers insights in the practical steps in the development of a fidelity assessment tool which can be used by other intervention developers.

The studies reported on in this thesis addressed the development of suckingpatterns in preterm newborns. Preterm infants often have problems learningto suckle at the breast or to drink from a bottle. It is unclear whether this isdue to their preterm birth or whether it is the consequence of neurologicaldamage. From the literature, as well as from daily practice, we know thatthere is much variation in the time and in the way children start suckingnormally. Factors such as birth weight and gestational age may indeed berisk factors but they do not explain the differences in development. A smallspot-check proved that most hospitals in the Netherlands start infants onoral feeding by 34 weeks’ post-menstrual age (pma). By and large the policyis aimed at getting the infant to rely on oral feeding entirely as soon aspossible. The underlying rationale is to reduce the stay in hospital, and theidea that prolonged tube-feeding delays or even hampers the development ofsucking.
