Family-Centered Intervention for Preterm Children: Effects at School Age and Biosocial Mediators

Study Overview
=================
Brief Summary
-----------------
This study is to extend our previous research to longitudinally examine the effectiveness of intervention programs (FCIP and UCP) for VLBW preterm children in Taiwan at seven years of age. Gender and maternal education level matched term children will also be included to serve as the reference group for comparison of developmental outcomes. The intervention had been delivered from birth to one year of corrected age in the previous study. Effectiveness examined will include child and parent outcomes. Primary outcome refers to measures of child neurobehavioral and neurophysiological functions. Neurobehavioral assessment includes cognitive, motor and behavioral measurement. Neurophysiological assessment refers to electroencephalogram/event-related potential examination and cognition/motor dual tasks that will be used to investigate the neurological pathways underlying the effective intervention. Secondary outcomes refer to child growth and health, and the quality of parenting measures.

Detailed Description
-----------------
Preterm children present more cognitive impairments, psychological and behavioral problems, motor and coordination impairments than their term counterparts. These impairments may cause the difficulties of learning and adaptation at the school age when facing multiple and complicate environmental stimulations in preterm children. Accumulating data on early intervention for preterm infants in Eastern and Western countries have demonstrated short- to medium-term benefits on enhancing child neurodevelopment outcomes. However, rare studies have examined the effectiveness of early intervention for preterm infants and its underlying neural mechanism. To meet the contemporary concept of family centered care, we have developed a family-centered intervention program (FCIP) for preterm infants with very low birth weight (VLBW, birth weight <1,500 g) in Taiwan and have found short-term developmental benefit with respect to a usual care program (UCP) via a multi-centered, randomized controlled trial. Therefore, this three-year project is aimed to continuously follow-up the effectiveness of FCIP on child and parent outcomes in VLBW preterm infants at school age. A total of 275 VLBW preterm children (269 participants and 6 pilots) who had participated in our previous randomized controlled study and 45 term children will be assessed growth, health, neurobehavioral functions (cognition, language, motor and behaviors), electroencephalography and event-related potentials (in the resting state, cognitive inhibitory control and working memory procedures) and cognition/motor dual tasks at 7 years of age. Parents will be assessed for stress using the Parenting Stress Index/Long Form and quality of life with the World Health Organization Quality of Life- Brief Taiwan Version. The effect of early intervention for preterm children from the neonatal period to school age will provide important information to help medical professionals and public policy makers design effective intervention for Taiwanese preterm children. The continuous neurophysiological and neurobehavioral data are crucial for understanding the neurophysiological mechanisms underlying neurobehavioral changes following intervention.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Term infants<br>Healthy term infants | |
| No Intervention: Usual care program (UCP)<br>In-hospital and after-discharge intervention (telephone calls) | |
| Experimental: Family-centered intervention program (FCIP)<br>In-hospital and after-discharge intervention (clinic and home visits) | Other: Family-centered intervention program (FCIP)<br>* This program included in-hospital intervention, after-discharge intervention and neonatal follow-up. Five sessions of in-hospital intervention emphasized modulation of the NICU, teaching of child developmental skills, feeding support, massage, interactional activities and parent support and education. The 7-session after-discharge intervention consisted of 4 clinic visits and 3 home visits with specific care in modulation of home environment, teaching of child developmental skills, feeding support, teaching of interactional activities, and parent support and education.<br>* Other names: early intervention program;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Child: Neurodevelopment- The Wechsler Preschool and Primary Scale of Intelligence-Fourth Edition | The Wechsler Preschool and Primary Scale of Intelligence-Fourth Edition (WPPSIR-IV) measures cognitive development of children aged from 6 years to 16 years and 11 months old. The test structure of WPPSIR-IV includes 14 subscales and several levels of interpretation: verbal comprehension index, perceptual reasoning index, working memory index, processing speed index and full scale intelligence quotient. The scaled score of each subscale ranges from 1 to 19. The total scaled score is the sum of the subscale scores ranging from 10 to 190. The full scale intelligence quotient will be converted from the total scaled score with a higher value indicating a better performance. | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Child: Past medical history | Past 1-year medical history is recorded by parental interview. | up to 2 years | 
| Child: Academic performance | Parent interview | up to 2 years | 
| Child: Neurodevelopment - Movement Assessment Battery for Children- 2nd Edition | The Movement Assessment Battery for Children- 2nd Edition examines the motor performance in children aged 3 years to 16 years and 11 months. The assessment contains eight items that measure a child's performance of age-appropriate tasks in the aspects of manual dexterity, aiming and catching, and balance. The scaled score of each subscale ranges from 1 to 19. The total score is the sum of the raw scores of the subscales and can be converted to scaled score, ranging from 10 to 190, and percentile. A higher score indicates a better performance. | 2 years |

| Child: Event-related potential (ERP) | Event-related potential (ERP) will be measured in the cognitive inhibitory control and working memory procedures and cognition/motor dual tasks with ERP technique for the participating children at 7 years of age. | 2 years | 
| Parent function-pressure | Parenting Stress Index measures stress of parents of children aged 1 month to 12 years. The total score ranges from 94 to 486, with a higher score indicating a higher stress. | 2 years | 
| Parent function-quality of Life | World Health Organization Quality of Life- Brief Taiwan version has a total score ranging from 34 to 170. A higher score indicates a better quality of life. | 2 years | 
| Child: Behavior - Child Behavior Check List/ 4-18 | The Child Behavior Check List/ 4-18 is a parent-report questionnaire designed to assess the behavior problems in children at 4 to 18 years of age.
