Impact of Picture Book Reading on Preterm Infant Stability, Parental Anxiety, and Parent-Child Attachment

Background The birth and survival rates of preterm infants in our country have significantly improved. However, due to the immaturity of their autonomic nervous systems, preterm infants are at risk of complications stemming from unstable vital signs. This instability often induces anxiety in parents, which can further impact their psychological adjustment and hinder the establishment of a secure parent-child attachment. Consequently, this study aims to develop a systematic intervention program using picture book reading to improve the cardiopulmonary stability of preterm infants, alleviate parental anxiety, and enhance the parent-child bond. Objective To evaluate the effects of a parent-child picture book reading intervention on the cardiopulmonary stability of preterm infants, parental anxiety during hospitalization, and the parent-child attachment relationship. Methods This study will employ a randomized controlled trial (RCT) design. Participants will include preterm infants and at least one parent from the neonatal intensive care unit (NICU) and neonatal intermediate care unit of a medical center in northern Taiwan. A total of 88 pairs of preterm infants and their parents will be recruited and randomly assigned to either the experimental or control group. The intervention consists of parents reading picture books to their preterm infants, starting at a corrected gestational age of 28 weeks and continuing until 36 weeks and 6 days. Data will be collected at multiple time points, including measurements of heart rate, respiratory rate, oxygen saturation, and heart rate variability. Subjective data will be gathered using the State-Trait Anxiety Inventory (STAI) and the Parent-Child Attachment Scale, while objective data will be recorded via physiological monitors and heart rate variability analyzers. Statistical analyses, including independent samples t-tests, repeated measures ANOVA, and generalized estimating equations (GEE), will be performed to compare the intervention's effectiveness. Project Goal To develop and evaluate the effectiveness of a parent-child picture book reading intervention program for preterm infants. The findings aim to inform pediatric clinical care practices and support the health and well-being of families with preterm infants.
