Descripción detallada
The study will test continued long-term intervention effectiveness into adolescence of very early born US preterm infants, who participated in a randomized Newborn Individualized Developmental Care and Assessment Program (NIDCAP) trial, conducted by the principal investigator, while the infants were cared for in the NICU for the first three months after their very premature births. All adolescents to be studied participated as newborns and were assigned either to control care (standard NICU care available at the time), or to experimental care (NIDCAP developmental care, with weekly bedside observations and with daily NIDCAP developmental specialist support to parents and staff), from NICU admission until 2 weeks (w) after expected full-term due date ('corrected' age [CA]).
The strongly brain-based theory underlying the approach to earliest intervention described here has been tested in several experimental studies, which are designed to investigate the effects of planned purposeful modification of experience for very early born infants, who spend the third trimester of gestation in the NICU. NIDCAP is based on an approach which utilizes close observation of each infant's thresholds of moving from organization to disorganization and stress, as exhibited by the infant's behavior. Care and environment are then continuously dynamically adjusted, with the goal to increase the infant's self-regulation and organization and decrease the infant's stress. This individualized model of NICU care provides an opportunity to investigate the modifiability of very early born infants' brain function and structure and the possibility of reducing or altogether eliminating the disruption and disturbance of fetal brain development in the NICU. The randomized scientific trials to date, conducted by the PI and by independent investigators at other settings after formal training show consistent significant neurobehavioral and neurophysiological improvements for the experimental groups across sites and studies.
All the adolescents to be studied were evaluated comprehensively at 2wCA and 9 months (m) CA in terms of not only the commonly measured demographic, medical background and severity of illness variables, but more importantly in terms of comprehensive neurobehavioral and EEG outcome measures, analogues of later developmental competence and disability.
The design of the current study of adolescents is that of a randomized controlled trial (RCT) with two parallel groups (control and experimental), with the question of the independent variable 'group effect' on two dependent measures (adolescent physical growth and cognitive development). In addition to group status, the contribution of four additional independent measures on outcome will also be evaluated: Parent socioeconomic status, parent cognitive function, adolescent physical function and adolescent psychosocial function. The outcome examiners will be blind to subject group status throughout. The design assures a true experimental test of the NICU intervention effects in adolescence.
The significance and importance of the study lays in the unique opportunity to evaluate comprehensively in adolescents the long-term neurodevelopment, learning and adaptive outcomes due to developmental care intervention received in the earliest stage of development. This will be the first study to test the long-term effectiveness of modification of experience in the NICU in a brain-protective, learning-enhancing model for very high-risk, very early-born preterm infants. The importance of the study lies in its potential to contribute significantly to the understanding of preterm brain development in relationship to long-term mental and adaptive functional outcomes in adolescence for the highly jeopardized and growing group of very preterm children. The results are expected to be of key importance in decision and policy development for the evidence-based targeting of sparse special education resources.

Newborn Individualized Developmental Care and Assessment Program (NIDCAP) utilizes close observation of each infant's thresholds of moving from organization to disorganization and stress, as exhibited by the infant's behavior.
Care and environment are then continuously and dynamically adjusted to increase the infant's self-regulation and organization and decrease the infant's stress.
This individualized model of NICU care provides an opportunity to investigate the modifiability of very early born infants' brain function and structure and the possibility of reducing or altogether eliminating the disruption and disturbance of fetal brain development in the NICU.
